Barbeck from After Later Audio is an expansion module for the 4-channel Stereo mixer Bartender. The two Barbeck channel strips have the same features as the main module and are equally suitable for Stereo and mono signals. Gain, FX send, panorama and volume can be adjusted for each channel. A toggle switch can also be used to select whether the FX send control works pre-fader or post-fader and refers to send 1 or 2. Switches for mute and cue (pre-listening) round off the channel configuration. As volume and pan can be modulated via control voltage, each channel can function as a stereo VCA with VC panning if required. Bartender is absolutely necessary to operate Barbeck, otherwise the expander will not work.
