The WA76-A accurately reproduces one of the fastest and most powerful studio compressors of all time known for its extra grabby attack, powerful dynamic control, and vintage analog grit. Using premium and custom components like O-12 (input) and 5002 (output) transformers from CineMag, WA76-A achieves authentic 76 blue stripe-style compression, known for its gritty preamp stage with unmistakably analog character. Added modern controls to achieve parallel compression, active & true bypass, selectable input impedance, and sidechain flexibility make WA76-A an ideal choice for modern recording workflows that require vintage tone shaping. WA76-A recreates the legendary tone & control of the vintage 76-style compression used in studios by artists like Jack White, The Beatles, David Bowie, Led Zeppelin and many more.Main Features:100% Analog Discrete FET CompressorFaithful Recreation Of The Vintage Blue Stripe 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 600 Input Impedance AttenuatorSelectable 10k Input Impedance To Better Match Modern Audio Interface Specifications100% Dry-Wet Mix ControlVariable Sidechain High Pass Filter: 30 – 300Hz, 12dB/Octave 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 S – 800 | Release: 50 mS – 1.1 SecondAll-Buttons-In Setting For Experimental & Hard-Limiter TonesFrequency Response: 1 dB 20 Hz – 20 kHzBalanced XLR & TRS Inputs & OutputsTotal Amplifier Gain: 58dBSignal-To-Noise Ratio (SNR): 86dB (a-weighted)Total Harmonic Distortion Ratio (THD+N): -62dB (at -13dBu)Specifications:Product Description & External Specs (Per Channel):100% Analog Discrete FET CompressorFaithful Recreation Of The Vintage Blue Stripe FET Compressor With Added Recording FeaturesVU Meter Options: Gain Reduction | +8dB Output | +4dB Output | Off Powers off unit100-230v IEC Inlet Universal Power SupplySelectable 10k Input Impedance To Better Match Modern Audio Interface Specifications100% Dry-Wet Mix ControlVariable Sidechain High Pass Filter: 30 – 300Hz, 12dB/Octave Stereo Link & External Sidechain AccessActive Bypass For Running Unit As Line Amplifier & True Bypass Option For A/B Comparisons2U 19 Rackmount ChassisAll-Buttons-In Setting For Experimental & Hard-Limiter TonesBalanced XLR & TRS Inputs & OutputsComponents & Internal Specs (Per Channel):Class-A Line-Level Output Amplifier100% Discrete Audio Signal Path Using 600 Input Impedance AttenuatorUtilizes Premium O-12 Input & 5002 Output Transformers From CineMag USAPerformance Specs (Per Channel):Vintage-Spec Attack & Release: Attack = 20 S – 800 | Release: 50 mS – 1.1 SecondFrequency Response: 1 dB 20 Hz – 20 kHzTotal Amplifier Gain: 58dBSignal-To-Noise Ratio (SNR): 86dB (a-weighted)Total Harmonic Distortion Ratio (THD+N): -62dB (at -13dBu)
