A group of engineers may not agree on much and that's a good thing. But one thing they all like is options. That's why Warm created the WA76 Revision D compressor. The WA76-D is a faithful recreation of a 76-style compressor with a revised preamp stage. It leans on premium ceramic & electrolytic capacitors and metal film resistors to offer cleaner, low-noise gain on the front end while retaining the punch, warmth, and character of the analog circuitry it shares with the original Rev-A version. The trademark "grabby" compression is there along with the familiar attack, release, ratio, input, output, and meter display to make it feel like your working with an old friend. But "getting the band back together" doesn't mean you need to live in the past, so Warm added some "I wish" features to the WA76-D. You get stereo linking, dry/wet mix for parallel compression, an external sidechain, selectable input impedance, active & true bypass, plus a variable sidechain high-pass filter to make sure the low end behaves. Each unit is hand-tested and inspected by Warm Audio's dedicated team in Austin, TX, guaranteeing superior quality and performance. Can't decide on which WA76 to get? Try one of each. It's all about options after all.Warm Audio WA76-D ApplicationsAdd Polish & Dynamic Control To VocalsPerfect Drum Room/Overhead Mic CompressionTight Acoustic Guitar Rhythms For Dense Track CountsDynamic Control For Heavy Electric GuitarsWarm Audio WA76-D Features100% Analog Discrete FET CompressorFaithful Recreation Of The Vintage “Rev D” FET Compressor With Added Recording FeaturesVU Meter Options: Gain Reduction +8dB Output +4dB Output “Off” Powers off unit100-230v IEC Inlet Universal Power SupplyClass-A Line-Level Output Amplifier100% Discrete Audio Signal Path Using 600Ω Input Impedance AttenuatorSelectable 10kΩ Input Impedance To Better Match Modern Audio Interface Specifications100% Dry-Wet Mix ControlVariable Sidechain High Pass Filter: 30 - 300Hz, 12dB/Octave ¼” Stereo Link & External Sidechain AccessActive Bypass For Running Unit As Line Amplifier & True Bypass Option For A/B Comparisons2U 19″ Rackmount ChassisUtilizes Premium O-12 Input & 5002 Output Transformers From CineMag USAVintage-Spec Attack & Release: Attack = 20 µS - 800 Release: 50 mS - 1.1 Second“All-Buttons-In” Setting For Experimental & Hard-Limiter TonesFrequency Response: ± 1 dB 20 Hz - 20 kHzBalanced XLR & TRS Inputs & OutputsTotal Amplifier Gain: 53dB Signal-To-Noise Ratio (SNR): 86dB Total Harmonic Distortion (THD): -64dB (at -8dBu) Warm Audio WA76-D Single Channel Clean Gain Discrete FET Compressor.
