Manufactured by Q2 Audio in close collaboration with Audio & Design, the F765 is a remake of the F760-N module and has now been adapted to the 500 series modular rack system
It is authentic in every detail and reproduces the exact sonic qualities of the original product.
Using the original discrete analogue circuit design employing a feedback FET technique and maintaining the use of the same components that give this product such a distinctive sound, the new F765 compressor/limiter will add dynamic punch to your sound as well as controlling peak excursions.
The original F760-N module was used by major recording artists worldwide throughout the 60s, 70s, and 80s. This famous, iconic processor was instrumental in shaping the sounds of that era. Now as the F765 it returns to take a worthy place in the ever-popular 500 series rack system with it's unique signature on the sounds of today.
Features
Single channel level control offering simultaneous compression gain reduction with peak limitingPrecision calibrated compressor/limiter threshold control which allows the user to "dial up" the amount of compression required before peak limiting occursSwitched Compression values from 1:1 (amplifier), 2:1, 3:1, 5:1, 10:1 & 20:1 (limiter)Auto dual platform release function - allows fast transient recovery on a "build-up" slow release
Specifications
Input: 10K ohms Unbalanced
Output: Transformer Balanced (Cinemag CMOB-3L) Max output: 20dBu, 18.5dBm
Metering: Sifam Fast Responding analog meter
Stereo Linking: Must order as stereo pair
Power requirements: +/-16V DC @ 70mA per rail (brief 400mA turn-on surge).
System Gain: 34dB with input/output attenuators fully open. Unity gain in Bypass mode
Thresholds
Peak Limiter: +14dBu maximum with unattenuated output. Referred to unattenuated input level 20dBu
Compressor: Calibrated with reference to Peak Limiter thresholds and marked 0 - 20dB in 2dB steps. (Reference to unattenuated input level this is -20dBu to -40dBu)
Release
Peak Limiter: 250mS,Compressor: 25mS, 50mS, 100mS, 200mS, 400mS, 800mS, 1.6 secs, 3.2 secs + Auto release function
Attack
Peak Limiter: < 250uS for 100% control of overshoot - without any over limiting. (measured at 1KHz for 10dB gain reduction)Compressor: 250uS, 2.5mS, 25mS
Distortion: Measured at 1KHz for 10dB compression & 3.2 secs release time.
Compressor: at +10dBu threshold <0.1% (typically 0.04%)
Peak Limiter: at +14dBu threshold <0.3%
Frequency Response:
Balanced: < -0.5dB at 20Hz & < -0.75dB at 20KHz
Signal - Noise Ratio:
Referred to Peak Limiter threshold level as set by output attenuator: better than -80dB (Measured with low pass filter -3dB at 25HKz)
Stereo Matching
Control volts matching on compressor to within ±1dB of each other, consequently no image shift during operationSelectable Peak Limiter operationPeak Limiter on - off or Pre-emph (50uS time constant)
Indicators
