Praga

A 20 HP four-channel voltage-controlled stereo mixer. Each channel has a VOL attenuator on its graduated dial, an illuminated ACTIVE | MODE button that mutes it without clicks and chooses how its VOL CV acts (unipolar, green, or bipolar, red), a PAN knob with its CV input, a bipolar AUX knob sending post-fader to aux A or B, a five-LED level meter and a direct VCA OUT. A stereo sum, two aux sends and two stereo aux returns complete it; the Hrad expander and further Pragas chain on the back.
