MIX1
INSTALLATION SHEET
AND OPERATORS MANUAL
MIX1 General Description:
The MIX1 is a mixer/preamplifier that includes 6 channels that each include a microphone input at screw terminals
and an aux input at an RCA jack. A seventh aux-only channel has a front panel switch to select one of two rear
panel aux input jacks. A mute-select switch allows either for channel 1 (Mic input or Aux input) to mute all other
channels, or for channels 1 through 6 to all mute the channel 7 aux-only input. The post-master-volume-control
outputs include a balanced line level output at screw terminals, a balanced mic level output at screw terminals, and
an unbalanced main output at an RCA jack. A pre-master-volume-control tape output is provided at an RCA jack.
An RCA jack is also provided to link the mix bus of one MIX1 to another MIX1 so that all inputs appear at all outputs.
A low cut filter switch is included which can reduce the bass response for use in reverberant spaces (like
gymnasiums) and act as a horn protection filter (trumpet protect) when paging horns are being used.
