Fink Analog Audio CS1-FA Mono Channel Strip

The CS1-FA is a complete Channel Strip - featuring a tube Preamp, a passive Parametric EQ, and a FET attenuator Limiter. The limiter has a single band of parametric EQ in the sidechain circuitry that lets the limiter be used for De-essing or De-Splosing. There is also a headphone amplifier with Level control, that monitors whatever the VU meter displays ( Preamp output, Limiter output, and Gain Reduction). When the Meter Switch is in the GR position, the phones monitor the output of the sidechain filer so you can tune the De-ees or De-plos by ear.

The Preamp section is a three tube design in the vintage Putnam console style, with continuous Gain and Level controls. The Equalizer is a passive parametric three-band EQ in the classic Pultec style,

with all the familiar frequencies and curves of the EQP-1A. The Limiter section is a unique two tube implementation of the UREI 1176, preserving the FET attenuator character and controls of the original, while delivering a smooth vacuum tube sound of it’s own.

Our products are designed by veteran UREI, Crest Audio, and Universal Audio design engineer, Dennis Fink. Manufactured in the USA (we outsource to New Jersey), each is tested and final assembled by the designer. We use the best electronic components for professional audio signal processing.

 

Preamp Controls Input - select and pad

(MIC 0dB, -10,-20,-30, LINE, switch to DI) Direct Input - Hi Impedance Instrument Gain - preamp trim (-10dB to +10dB) Output - pre output level to EQ (0 to 11) +48 - phantom supply to mic

PEQ Controls EQ Bypass - EQ in or out MID BOOST - midband boost (0dB to +10dB) MID BW - mid bandwidth (wide to narrow) MID FREQ- midband frequency

(3k, 4k, 5k, 8k, 10k, 12k, 16k) HI CUT - highband attenuation (0dB to -10dB)

HF - highband frequency (5k, 20k, 15k) LO BOOST - lowband boost (0dB to +10dB) LF - lowband frquency (20,120, 60Hz) LO CUT - lowband attenuation (0dB to -10dB)

LIMITER Controls BYPASS - limiter in/out, bypass controls INPUT - input to FET attenuator, sets threshold (0 to 11) OUTPUT - output make-up gain (0 to 11) ATTACK- dynamics attack time (20 to 400uS) RELEASE - dynamics release time ( 2 to 200mS) RATIO - compression slope

(1:1, SOFT, 2:1, 4:1, 8:1, 12:1, 20:1, ALL) METER - (PRE output, Gain Reduction, LIM output)

De-Ess / De-Splos Controls BYPASS - SC EQ in/out, bypass controls BOOST/CUT - bandpass filter gain (-12 to +12 dB) x1 / x!0 - 50 to 500Hz or 1k to 10kHz frequency range FREQ- sweeps filter over tune range
