After Later Audio Barback Eurorack Mixer Expander Module (Bartender)

Two channel expander for Bartender that can be cascaded to add as many channels as you like (but we’ve only tested up to 16ch).

Mixer section
Each channel has the following:

• Stereo or mono – Each channel can be treated as a stereo channel or a mono channel with two summed inputs.
• CV inputs for both panning and level control
• Two send buses – You can route each channel to one of two send buses.  Each send bus is stereo.  You can choose if you want the send to come before or after the level/panning controls.
• Mute – The mute has both latching mute (up) and a momentary mute (down).  The mute uses a capacitor to slow the turn off and on of the mute action.  So it is mostly click-less, but you may find an occasional pop.
• Cue bus – You can route each channel to the cue bus.

Expandable Mixer Series

• Bartenders can be cascaded to create 8ch, 12ch, or 16ch mixer.  The main level is what is sent the main level control can act as a group control.
• Barbacks can be added to add 2ch to your mix.  Barbacks can also be cascaded enabling up to a 16ch mixer configuration.
• Send-VCA can be added for CV control of the level of the send.
• DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules.  Connecting the in and out pins will send/receive the audio into the next module.
