2U rack-mount unit. The two channels are suitable for mono, stereo or independent operation, with the option to link to other units for multi-channel use. At its core, the 33609/N retains the same basic circuitry as earlier discrete models, now with extra control options and a classic appearance.
Front Panel Description power switch: Switches the unit on or off. The switch is illuminated when the unit is ON gain reduction meters: Show the amount of gain reduction occurring on each channel, in decibels external / internal: In internal mode all front panel toggle switches operate normally and the adjacent LEDs light red.

(COMPRESS) recovery ms: Sets how slowly the gain reduction subsides after a loud passage has ended. In the a1 and a2 positions the recovery time is self- adjusting; recovery is rapid for transient peaks but slower for persistent high levels, so the impression of normal dynamic range is better preserved (COMPRESS) gain: Sets the amount of make-up gain applied to the compressed audio.
*Note: EITHER a “L+R bypass” switch (Pin#2 as in older 33609s) OR the separate left and right bypass switches (Pins#10 & #11 -33609/N only) should be implemented, but not all three at once which will lead to confusion because of the way the latching logic works.
Rack Mount Instructions Elevated Operating Ambient- If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (50°C) specified by the manufacturer.
