DRIVE - turning it clock wise increases compression, which is way more sensible than counter clock wise!
MAKEUP - variable control that adds up to 15dB gain after the compressor section to correct for lost level.
MIX - variable control that allows you to mix between the input signal and the compressor output (post the makeup control).
COMP IN - Push button switch to bypass or engage the compressor, (hard wire bypass).
BASS - Push button switch that engages a high pass filter into the side chain to reduce the sensitivity of the compressor at low frequencies.
METER G.R./O.P. - Push button switch to select the display on the VU meter of the amount of gain reduction or the output level.
ATTACK - rotary switch with FAST (1mS) 25mS, 50mS selections plus our excellent AUTO mode.
RELEASE - rotary switch selects recovery time of 100mS, 200mS, 400mS, 800mS, 1600mS and a superb AUTO mode.
RATIO - rotary switch with 4 settings for depth of compression, 2:1, 5:1, 10:1, 20:1.
There is also a handy power ON/OFF switch and a channel A/B LINK switch which soft links the sidechain circuit which is useful when the Velox is used on stereo mixes.
