Audio Mixer
DESCRIPTION
A simple 3 channel AC Coupled (Can be modified for DC Coupled see below) mixer is a must for any 4U Modular system! Channel 1 has a dedicated phase invert w/ mute toggle.
DETAILS
3 AC coupled inputs
3 unipolar attenuated inputs (one with invert/mute switch)
Current: TBD
PCB Size: 6” x 1”

** 4U Modular is a term used for the format most commonly known as “Serge Format” or “Loudest Warning Format”. Out of respect for the ever growing format, 4U Modular is the easiest way to refer to it. More Specifically it refers to the panel height and mounting hole style. 4U Modular will patch up just fine with other 4U "Serge" formats such as "Random Source", but it will not mount in RS boats or Buchla Boats (or power off Buchla power for that matter). An info page about this will be added to the website soon to make this a lot more easy to understand.
