Drawmer 1976

Stereo 3-band Saturation & Width Processor
By JG Harding

The input section gives you an indication of the ideal input level. The yellow LED on most of the time with occasional flickers of the red gives great results on many sources.

Could this be the ultimate analogue 'vibe box'?

Many largely in-the-box producers like to turn to a hardware vibe box on occasion — something to add real 'analogue mojo' to their projects. But as they can already access pretty much any effect they could want in the DAW, the hassle of routing signals out of the box is only really justifiable if it achieves something that can't be done in said box. Having started off working entirely in the box, I amassed a fair amount of outboard over the years, but as time has passed my justifications for owning all this outboard have grown increasingly esoteric.

Now, despite owning some nice reverbs and EQs, pretty much all my reverb and EQ moves are once again done with software. Yet, for saturation, compression and distortion I use a combination of software and hardware, and when hoping to inject some analogue vibe I think that hardware generally still has the edge. I tend to look for something a bit 'different', and while I'll often turn to my three Rupert Neve Designs 5042 'tape effect' saturators, an old transformer-laden Alice desk, and various compressors, including a Drawmer 1968 MkII, I'm always on the lookout for new 'flavours'. So when I learned of Drawmer's new 1976 multiband saturation and stereo-width processor, I had to give it a try!

One man's 'saturation' is another's 'distortion', but the name of the game with 'saturators' is to add aesthetically pleasing harmonics. In the analogue domain, this can be achieved in many ways, from overloading transformers and valves, to pushing transistors and analogue tape beyond their specifications. Like the 1974 EQ that Bob Thomas reviewed last month (https://sosm.ag/drawmer-1974), Drawmer's 1976 aims to deliver a broadly '70s sound — essentially, they're going for the vibe you can achieve by pushing the channels of a transistor-filled 1970s mixing console. But Drawmer also see the 1976 as a sort of analogue interpretation of the tube section of their old, all-digital DC2476 mastering processor, and a glance at the facilities on offer certainly hints at 'controllable vibe'.

Controls & Construction

The 1976, with its yellow and black knobs and simple, bold layout, is unmistakably modern Drawmer. Connectivity is easy, with XLR ins and outs and an IEC mains inlet. The internal layout is also neat and pleasing, including ±15V power-rail indicator LEDs that let you know the hefty centre-tapped toroidal transformer is doing its job. While there's a lot to commend the design, there are also a couple of mildly curious decisions.

Connectivity to your interface or other gear is via balanced three-pin XLR connectors with the mains power switch on the far left.

First, the power switch is on the back, next to the IEC inlet, where it's of little practical use when bolted into a rack. Second, while I definitely have no complaints about the mains power being stepped down via a toroidal transformer, I'd have preferred the 230V/115V mains voltage selector to be on the rear panel than inside the box. Not only would that mean you didn't have to open the unit to change the setting (a minor gripe, since you'd do that very rarely) but it would ensure there was an external indication of the current setting.

This is a stereo processor rather than a dual-mono one (a single set of controls applies to both channels), so it naturally lends itself to bus processing, whether for a whole mix or an instrument group within the mix, and to work with stereo sources such as drum loops. You could alternatively use a single channel for mono processing, and you can also hit the mono button to check the effect of any stereo processing on the mono mix. Still, the 1976 aims to shine on stereo sources.

There are three bands (low, mid and high), and the crossover frequencies are continuously variable: the low-mid crossover ranges from 70Hz to 1.5kHz; the mid-high from 800Hz to 15kHz. These generous ranges allow some crossover in the crossovers, if you will. There's a master input level, with a yellow LED indicating ideal level and a master output control for taming the onward signal. Lastly there's a master bypass for quick A/B comparison of your settings with the dry signal. There's no master mix or wet/dry control, so if that facility is important to you, you'd have to achieve it in your DAW or with traditional parallel analogue techniques.

Each band has the same control set (Saturate, Width and Level), each control simply increasing/decreasing the strength of the effect in question. The manual is great. It gives the user a rundown of the effects and their intended uses, and the signal flow, and it includes recall sheets and even a frequency chart with suggested crossover points. So beginners won't be intimidated. Above all else, Drawmer say to "use your ears" — universally good advice, but especially useful when it comes to saturation and distortion.

The neat internal layout includes ±15V power-rail indicator LEDs to let you know all is well. A voltage selector, just below the two earth lugs at the top right, allows the unit to be set to work with 115 or 230 Volt mains power.

Peaky Blinder

The first thing to note when you start using this thing is that the input control and its associated lights are really helpful. If your source is peaking at the yellow light, you'll get saturation across the whole range of each saturation knob. If it's peaking above this, you'll get more distortion as you turn up the saturation knob. In a way, this means that the 1976 has a couple of roles: you can achieve a subtle effect by feeding it lower levels, or choose to blow things out entirely, much like when using a real mixing desk. An easy way to establish a rough operating level is to set the input so the signal you want to process lights the yellow LEDs all the time but its peaks tickle the red ones. This will get you in the right ballpark very quickly, but you should feel free to vary the levels for subtler/more aggressive results — I found that setting the level so the red light flickered on and off just a little typically made everything sound that bit more 'exciting'.

Starting with a full stereo mix, I dialled in some saturation and used the mutes to listen to each band in isolation. Interestingly, when trying to listen to the low band alone, muting the mid and high bands doesn't appear to completely remove them — some signal gets through, probably due to the use of fairly gentle filters — but the other two bands seem to interact with the mutes as expected.

The saturation side of things made for a nice mastering tool. I found that setting the low band to control below 100Hz and the high band around 10kHz and up allowed a modern, lean tone to be dialled in, with thick bass and a little glitter on the highs. As I increased the saturation, the level also increased, so balancing your main input, the saturation for each band and the output for each band is important to controlling the sound. As with all saturation, I found it very easy to overdo things, but with subtle settings the results were pleasing.

The saturation character is great for thickening up group busses, and since it's multiband you can focus the processing on a specific frequency range, which can be really useful. The bands aren't super surgical, and the roll-offs on the crossover filters are nicely balanced, and this has the effect of separating the bands without making them feel disconnected. For me, a favourite target for the 1976 saturation was the drum bus — I can definitely see it being normalled into a patchbay, ready to deploy on the drum bus each and every time. In this role, when using similar crossover frequencies to those I've just described, but with the low crossover set just a touch higher and applying more assertive saturation, I was rewarded with a nice, solid thickening of the sound. It's an effect similar to that of pushing channels on a nice desk quite hard. Couple it with a nice compressor and you'd be addicted in no time!

For individual instruments, fine-tuning the crossover settings is vital if you're to achieve the best sound. By way of example, with acoustic guitar I found that a thinner-sounding instrument could be beefed up using hefty saturation below 250Hz and a little push in the mid-range, while leaving higher frequencies alone. A thin vocal can easily be given some richness and push with a tight mid-range band saturating just where the recorded voice is lacking. As you might imagine, distorted guitar loves the mid-range control too; it can deliver some lovely '70s-style crunch and thickness.

Wide Load?

The stereo width control in each band is an M-S balance control. The source is encoded (after any saturation) to Mid-Sides stereo, the knob adjusts the balance of the Mid and Sides channels to increase or decrease the stereo width in that band, and the signal is then decoded back to L-R stereo.

Though a great idea in theory, I found the implementation on the review unit less convincing, as although narrowing the stage was easy, the widening effect ventured too quickly into special-effect territory. Figuring that something might be amiss, I asked Drawmer about this, and they tell me that only the review unit and a few early production units exhibit this behaviour, largely because the third-party testers seemed to have very different preferences. Happily, Drawmer say that these pots will have a much more useful degree of control (without reducing the maximum amount of effect that can be applied) in all production units by the time you read this review.

It's worth noting that altering the Mid/Sides balance affects the perceived level, so you need to juggle the band's width and level controls to achieve the desired result.

For me, a favourite target for the 1976 saturation was the drum bus — I can definitely see it being normalled into a patchbay, ready to use on the drum bus each and every time.

Because You're Worth It

I judge whether a piece of hardware is 'worth it' when compared with the many low-cost or free software alternatives in a couple of ways: first, I ask whether I miss it when I have to use software; and second, I consider whether it offers a special vibe that my software and other processors can't. The 1976 ticks both boxes. Once you become familiar with the need to set your crossovers to suit the source material, and balance the makeup gain with the saturation and width controls, it doesn't take long at all to enhance a sound in a lovely way.

I can think of a handful of potential improvements that a MkII version might deliver in the future. Wet/dry mix and master stereo-width controls would extend the versatility, and a power switch on the front would be welcome. I could imagine a useful facility to apply automatic makeup gain for the saturation and level controls too, leaving the Level control as just a final overall level control for the band. That would facilitate faster A/B checking of the added effects.

But none of that takes away from what the 1976 already offers. It really does shine in giving the user access to a '70s analogue vibe using only a few knobs and the minimum of effort — it's all so quick and easy. And all the while, the 1976 adds that extra sparkle that only the 'real thing' provides.

The multiband nature of this thing makes it really versatile too, since it means that you can tailor the effect to suit various sounds: it's easy to dial up massive drums, crunchy guitars and sparkling vocal tones, without the hassle of setting up dedicated crossovers and using multiple units or plug-ins. The 1976 also complements other hardware and plug-ins well, especially tape simulators and units that lean more on smoother even-order harmonics.

All in all, then, despite a quirk or two, it's a really addictive unit that could prove a great addition to any in- or out-of-the-box studio. And it's available at an attractive price to boot.

Alternatives

There are plenty of pure saturation hardware options out there and a few stereo wideners, but the Drawmer doing it all in one is quite rare — and in hardware the multiband facility is rarer still. The Empirical Labs EL‑7 Fatso is a studio-stalwart saturator, while Rupert Neve Designs have their 5042 and 542 (500-series version) tape simulators, while selling a separate 5014 Stereo Field Editor.

Looptrotter's Sa2rate offer's simple saturation while Overstayer's NT‑02A saturator costs more but can push harder into distortion. At the subtler end of things Roger Mayer's 456 500-series unit emulates Ampex 456 tape on a Studer A80 tape machine. The most costly, and to my ears the subtlest, is the Anamod ATS‑1 tape emulator, though that's now only available second-hand and commanding several thousand dollars. When it comes to software, there are countless alternatives, but you probably already know that.

Harmonics & Overtones

The result of a -12dBFS 100Hz sine wave delivered to the Drawmer via an RME interface. The yellow input light representing ideal signal level is on, and low-band saturation is set to 3 out of 10. Here we can see the strong odd-order harmonics (300Hz, 500Hz and 700Hz etc.), with weaker even order harmonics (200Hz, 400Hz and 600Hz etc).
Here we see a -18dB 100Hz sine wave with saturation at 10.
Here a 100Hz sine wave at -12dB and saturation at 10, all other controls to 12 o'clock. At this point the third harmonic is nearly as strong as the fundamental frequency.
Here is a setting using 100Hz sine wave at -24dB input level and saturation at 10. Here the harmonics are quite subtle. The box interacts well with differing input levels, as a low input with a high saturation creates a slightly different result to a high input with a low saturation setting.

A sine wave is a mathematically pure tone oscillating at only one frequency. All other forms of instrument have some kind of harmonic overtone, noise or other distortion that make up their timbre. If we take a 100Hz sine wave as the starting point, and add sine waves at multiples of this frequency, each would be an overtone and harmonic. 200Hz is the second harmonic or first overtone, and is an even-order harmonic. 300Hz is the third harmonic or second overtone, and is an odd-order harmonic. 400Hz is the fourth harmonic or third overtone and is an even harmonic... and so on.

Musically speaking, even overtones are octaves and fifths, while odd overtones are thirds. But when applying harmonics as a saturation process for things like drums and vocals, it's easier to think of even harmonics as warm, soft and smooth saturation, and odd order harmonics as bolder, overdrive-like saturation. The 1976 blends both orders of harmonics together, but since its loosely emulating of a 1970s transistor console, the odd-order harmonics are a little stronger.

The harmonics themselves can be analysed by sending a 100Hz sine wave into the unit and monitoring the returned signal in a frequency analyser — here I've used the one in FabFilter's Pro‑Q equaliser (shown above).

Pros

  • Offers great, vibey saturation with a distinctly '70s edge.
  • Multiband processing makes the saturation so versatile.
  • Easy to use.
  • Particularly powerful on drums and guitars.
  • Unique, and complements other hardware and plug-ins well.

Cons

  • Power switch would be of more use if it were on the front!

Summary

The 1976 is a unique and, it has to be said, somewhat addictive multiband saturation processor, with some multiband stereo-widening facilities thrown in.
