When to Give Up
If you’ve followed my microphone reviews and opinions, you might know that I am a big fan of Electrovoice’s RE-18 Variable-D hand-held vocal mic. I bought my first RE18 in the 70’s, new, and I’ve owned a dozen or so since. In experiments with a variety of vocalists, I’ve found this microphone to be superior to almost every other live vocal I’ve ever used. In every area (except one), the RE18 excels: handling noise, off-axis rejection and frequency response, proximity effect control (Variable-D), max SPL, distortion, clarity, humbucking noise-rejection, and durability. The one negative, repairability, is the focus of this article.
At one time, Electrovoice offered a “lifetime warranty” on all RE series microphones. After a few years of downsizing, being aquired by a variety of conglomerates, and lowered expectations, that “lifetime” is currently being defined as a "limited lifetime warranty on the acoustic element (due to defect in materials or workmanship), defined as ten years from the last date of the products manufacture." EV seems to have “lost” all of the technical information regarding many of the company’s most respected products, including the RE18, but I suspect that mic went out of production in the late 80’s when EV had all but disappeared from professional audio. Even getting an EV tech support person to admit that the RE18 ever existed requires arm-twisting.
One of the best features of the RE18 was it’s amazing lack of handling noise. That capability as created by incorporating shock-isolation between the element and steel outer case that used butyl-rubber doughnuts and viscous damping fluid. The foam breath and pop filtering was pretty sophisticated, too. To this date, I have not been able to find anything resembling a description of the parts required to repair this shock isolation system and it’s clear that 30+ years of use or improper storage will turn all of those parts into an unrecognizable mess of disolving chemicals. The shock isolation system for my RE18 remains incapacited.
With the assistance of the one helpful tech service person at EV, I was able to obtain a replacement foam filter and Variable-D baffle for their current version of the RE16, but that is a long way from anything used in the original RE18 design. The RE18 used a 3-layer pop filter system, but the RE16 is just typical low density foam. The once-impervious to vocal plosives and sibilance distortion RE18 is rendered passable with the RE16 replacement material.
After decades of recommending this microphone to vocalists of all sorts, I have to give in to the facts and admit that without some sort of support from the manufacturer or someone who was once involved in the design and/or production of this wonderful microphone repairing the RE18 is no longer practical. And, except in incredibly rare instances, I think you will find that upon removing the metal screen that every RE18 is likely in desperate need of serious repair. Typically, the foam has turned to a nasty combination of dust and sticky adhesive and the rubber shock mounts are likely totally deteriorated and there is no evidence that the viscous damping fluid ever existed or any way to determine what it once looked like for the purposes of fabricating a replacement system.
The RE18 shows up often on eBay and Reverb.com; often with an asking price of $200-or-more. Knowing that the microphone is likely in an unrepairable and deteriorating condition, it makes no sense to invest that kind of money in a once-terrific instrument. I would not, under any conditions, pay more than $100 for an excellent condition RE18 and sight-unseen (and before disassembly and inspection) no more than $20 for an on-line sale. At the absolute least, ask the seller to remove the metal screen and take a picture of the foam being distorted with a finger or blunt object to determine if that material is in a state of extreme decay. Usually, when the screen is unscrewed and removed the foam will fall out in pieces and clumps of dust.

Product Review: DiGiCo SD9 Digital Console
When I decided to write up my experience with and opinion of the DiGiCo SD9 console, I suspected my less-than-positive opinion might be in the minority on this piece of expensive equipment. Often, people who spend a fortune on gear convince themselves it’s the best thing since sliced fingers. Most of my experience with live and studio consoles has been on analog equipment, but I was not only an early user of the Yamaha PM1D and did a fair amount of upgrade and warranty service for Yamaha between 2001 and 2007 on their PM1D and PM5D consoles. I have had an opportunity to mix on the AVID Venue and Midas M32 consoles a few times, also. I’m not digital-hostile, but I am not particularly fond of engineers who thing the world needs to revise how it spins because those engineers want it to. For starters, there are a variety of opinions from equally talented and experienced mixers regarding the DiGiCo design and ergonomic concepts. For my money (which, happily, isn’t involved here) it’s a no-brainer: the DiGiCo costs about $30,000 without I/O and the Avid Venue is about half that cost with many times the customer base. Even the new Midas digital consoles are considerably cheaper than the DiGiCo consoles and they have a 10 year warranty, vs DiGiCo’s 1 year coverage. The Midas M32 costs less than $6k and would more than do the job this small facility needs done. 96 input channels for a 450 seat facility is gross overkill.
I did some searching on the Web for other opinions of DiGiCo and found a few technical sites where the subject was discussed. For example, when asked for “general opinions about DiGiCo,” an obviously knowledgeable user said, “You probably don't hear much about them because they are rather pricey and usually only the top level companies/venues can afford them, but they are worth it. I think they are more prevalent in Europe along with Midas digitals than here in the states.” Another opinion from a tech clearly familiar with a variety of digital consoles was, “I'm sure that the UI could be learned with a fair amount of time and effort but it's not particularly user friendly especially when coming from experience with the more widely encountered Yamaha's and Avid's.” A tech who has “been touring with Digico consoles since 2007” said, “Users who complain that they are ‘hard to walk up to’ just need to take a moment to give it a chance, as we had to give all the digital consoles a chance that we have learned. With an on-screen layout that mimics an analog channel strip, operating a Digico console is quite easy. I have trained many users ranging from digital console newbies (a couple months ago I gave a training session to a company who bought an SD9 after only owning simple analog consoles) to seasoned touring pros on how to operate Digico consoles and I find that once a few workflow items are explained, people catch on quickly.” “Catching on” isn’t the problem. DiGiCo’s complete ignorance of or disdain for modern design and ergonomic concepts means catching on is about 1/10th of the battle. The problem is that the design lends itself to inefficient and simplistic work flow. I hope this review details some of the reasons why I found the SD9 to be one of the most user-hostile electronic devices I’ve used in years.
NOTE: When it comes to how seriously you take the points made in this review, please take into account that I have 50 years of analog console experience, failing eyesight, and almost zero interest in listening to live guys babble about “sound quality”; a concept so rarely heard in live music performances that I doubt few “professionals” in live music would recognize their own name if it were shouted at them by their mother in close quarters. There is a lot of audiophile fascination with fidelity from the clinically deaf crowd, in my opinion. However, I’m going to assume the sound quality is a given, because it is, and worry about the ergonomics and function of the console.
For starters, DiGiCo’s conceit is that there is something intuitive about a small screen in the middle of the console that describes the functions of 12 of 96 potential channels with no direct physical relationship to channel faders. The only controls lined up with the faders are mute and solo buttons, ID scribble pads, and LED VUs. That does not work for me. The large, asymmetrical physical and visual leap from the constantly in-use faders to the awkward miniature virtual channels on the screen in the upper middle of the console, and the continuous rotation controls at the right of that screen, the function selection buttons on the left of the screen, and another set of continuous rotation faders at the bottom of the screen (plus an alternative function selection button) pushes the limits of my eyesight and long-established habits. My motivation to adapt my lifetime of habits to the DiGiCo world is tempered by the knowledge that I won’t be working on this equipment often and would not choose to ever do so.
There is no labeling on the two channel buttons: solo and mute. The 100mm faders are pretty much the same as everyone else’s. At the channel input screen, the tiny and upper-most positioned channel VU meters are labeled and scaled in 15dB steps, so determining input signal precisely is difficult. If you select the input screen, the VU meters do not come with it. There are larger LED meters just above the channel ID LCD scratch pads. Those meters are more typically scaled, but since there is no correlation between the LCD screen channels and the physical channel location, using those more precise VUs is very counter-intuitive and, honestly, I was never convinced the two meters gave the same information because the scales are so different. Not having taken test equipment to the console, I’m not sure what headroom is available over the VU meter’s clip indication. The preamp has the typical 60dB of gain and the output is capable of +22dBu max output. Distortion is a fairly typical THD >0.05% at 1kHz, which is barely information in today’s far more useful multi-tone IMD measurement world.
DiGiCo’s SD9 touch screen is pressure sensitive, functionally, that an odd feature in today’s world of capacitive touch screens. As if that isn’t odd and off-putting enough, the screen is not particularly consistent in the amount of pressure required or where each button and control’s pressure points are located on the screen. I resorted to using the back end of a BIC pen for screen entry to minimize misses and false control selection. That helped, but didn’t consistently solve that problem. Not being able to use my fingers to make function selections and open and close screens meant making adjustments to practically any function was cumbersome.
A lot of the features I take for granted in a digital console are not available in the SD9: color-coded groups, individual channel automation, (Avid’s “Auto-Off”, for example), grouped faders and mutes, I/O naming, and probably a whole collection of other useful features I have yet to discover aren’t there. DiGiCo’s Snapshot feature allows you to automate the setup for scenes/songs and is useful for a lot of things, however automating several channels for a variety of things can get messy and, once again, the tiny buttons on the “global scope” touch screen make every change . . . challenging. The facility where I used the SD9 has a keyboard stored on a sliding shelf under the console, but every time I slid it back under the desk, the bump at the end of the shelf jogged something that caused a loud “snap” in the mains; probably a fiber optic connection issue, but it could be almost anything related to the console and its complicated connections. In the end, I mostly did my text entry on the cobbly virtual QWERTY keyboard on the screen. The automation capabilities of the SD9 are very 1990’s capability-wise. You can automate pretty much any of the SD9’s functions, but it’s all or nothing. Unlike Avid, Yamaha, or even Presonus channels that can be individually selected to track or record automation or not, when you select the input channel faders, mutes, pans, sends, or any other function to be automated with Snapshot changes, it’s all or nothing. “Mostly useful” is the nicest thing I can say about the Snapshot feature. If you use the console’s left side Snapshot “next” button to pre-arm the next Snapshot and try to trigger that move with the console’s right side Snapshot “next” button (instead of the left side’s “Fire” button), the selected Snapshot will be one past the one you pre-armed. I can’t guess what the British logic behind that would be.
The built-in plug-ins are fine and there are a few typical Waves plug-ins that can be inserted almost anywhere there is an insert in the signal chain. The problem is that DiGiCo works a lot harder than most console manufacturers to make it hard to figure out where the input and output connections actually are. Relabeling their obtuse equipment identification terminology isn’t an option. Like it or leave it, DiGiCo knows better than you how your I/O should be identified.
From reputation only, I understand the SD9 is a pretty durable console. It seems pretty tough, just based on the chassis construction. I haven’t seen the inside of the console and I wouldn’t pass judgment, one way or the other, on it’s durability until I have seen how the boards are mounted, what kind of connectors are used and how they are secured, and how the wiring harnesses are secured. In the past, Euro-designs have rarely impressed me in this regard, so I have my doubts. Based on the Sheldon Theater’s experience, there is no chance that I would consider using DiGiCo’s fiber-optic system on a road tour. In fact, I’d want to see a CAT5 connection to all equipment, looped and returned redundantly. In my experience, British equipment isn’t particularly durable or well-constructed and that would be one more reason I’d never consider a DiGiCo console for a touring rig. Your mileage may vary.
The SD9’s price tag puts it well into the most-expensive-in-class category; more like SSL than Midas or Avid. That makes choosing a DiGiCo console risky business. Like it or not, digital electronics should be expected to have a 3-5 year lifetime before regular maintenance becomes necessary. The DiGiCo’s 1 year warranty is a statement in the company’s product reliability expectation, in itself. I suspect that a majority of SD9 owners are unfamiliar with Return on Investment (ROI) calculations. Before you spend this kind of money on digital audio equipment, you should correct that deficiency. When this kind of gear is discontinued or the company bellies-up, or the gear just stays in use beyond that 3-5 year expectation, you will be regretting that big purchase decision unless you also received big earnings from the investment. The more complicated and sophisticated gear becomes, the harder it is to repair and the more likely it becomes that repair will be necessary. The SD9’s modular assembly makes doing big section repairs fairly easy, but when the warranty expires that design tactic will make repairs expensive. When the company stops supporting the product, it won’t be long before you can get great deals on used SD9’s. In fact, you can already buy a used “refurbished” (whatever that means) SD9 for about $0.30 on the original purchase dollar. No digital equipment holds value well, though, which should always be considered when you are counting up the dollars you plan to spend on equipment.
I’ve heard mention of fader glitches from other DiGiCo users, particularly on unused third and fourth layer faders. I experienced a master group fader suddenly dropping to “–inf” just before a show started, after 45 minutes of signal passing through the mains before the show. I have to admit that unexplained fader moves on group levels that are not part of any area I ever use is a deal-breaker for me. That sort of occurrence is completely outside of anything I have experienced with any other digital console, other than a first generation Soundcrap I was forced to use on a television remote truck for about a year. Some consoles have a function select that allows you to prevent any fader from moving unless there is a human finger on that fader, but that isn’t a DiGiCo option. It should be.
The console’s power supply noise probably isn’t a problem for most pop music acts, but it is a pain in the ass for the small theater production I was involved with. For example, when the theater was empty the FOH work position noise level was 69dBC and 46dBA while the majority of the audience seats were 56dBC and 44dBA, indicating that there is a lot of low frequency noise produced by the console and a fair amount of low-to-mid frequency energy; 10dB or more, in fact. Honestly, in this day of high efficiency, low noise computer power supplies, I think this much noise from audio equipment is intolerable. Since I was working for an average sound system level of 6-8dB over ambient, all that console noise made my job a lot harder than it needed to be.
I’ve written before about my bitch with DiGiCo’s bullshit WAVE drivers, but it’s worth mentioning here. DiGiCo is arrogant enough to believe that they are “special” enough to make obtaining their drivers for recording apps harder to buy than actual programs. You have to be a registered DiGiCo owner to obtain their damn drivers. When you do get them, good luck. Way back when Avid’s Venue came out, in 2005, my Location Recording class went to Duluth to record that city’s High School Battle of the Bands. We had our location Digidesign HD rack, a MacBook Pro, and absolutely no experience with the Venue console. We were able to get a session up and going in a few minutes. After a brief discussion with the FOH engineer about who would control what in the sessions, we were up and ready to record our first band within an hour of arriving. Three years after my local theater bought their SD9, the console has yet to be successfully used as a recording interface. The four events I’ve been asked to record were handled by using the DiGiCo D-Rack splitter and my own mic pres and recording interface. The local rep, other sound techs who were supposedly familiar with the SD9, along with the characters who sold this rig to the theater have been unable to make any sort of useful connection between all that “sophisticated British gear” and any recording program. In the meantime, I’ve managed to do location recordings on Behringer, Midas, and Yamaha digital consoles with damn near no serious issues. I’m sure DiGiCo sells their Waves-mismanaged drivers as some sort of “feature,” but I am generally disgusted.
Simply put, I’m not impressed. Between the poor ergonomic design, the high price, and the mediocre post-sale support, I think choosing the DiGiCo SD9 is more about status and conspicuous consumption than any functional or aural values.
