Description
This optional, compact circuit card installs internally in Millenium consoles and may be connected to any console audio
output(s) to distribute signal to multiple sources. The card features bridging inputs, low impedance outputs, and indepen-
dent level adjusts for each output.
Installation
Use the plastic pins supplied to mount the circuit card on any free slot on the console inside rear wall. Supply DC power via
the three wire cable from any auxiliary DC output connector on any lower console circuit board. The second DC connecter
can be used to supply DC to power additional console option boards.
Applications
Use the DA/MIXER to distribute program or audition audio, create a mono program blend or a “mix-minus” feed of multiple
signals. On analog Millenium consoles, the DA/MIXER may also be wired to loop through channel patch points (while
leaving the loop-through jumpers in place) to “pick-off” and distribute individual channel audio. The DA/MIXER, used in this
application, will balance and buffer the audio, maintaining the integrity of channel audio as it exits the console.
Each of the 8 outputs can be jumper programmed to deliver one or any mix of the 4 inputs. Thereby, multiple stereo outputs
can be created by jumpering one input to multiple outputs. A mono mix of stereo inputs can be created by jumpering a
signal output to multiple inputs. A “mix-minus” output can be created by jumpering one input to multiple outputs with
additional inputs to the same outputs.
When ordered with the console, this optional board will normally be factory installed and operational. For field installa-
tion, use the four plastic standoffs provided to mount the board on the inside rear console wall near the associated input
or output. Connect the 3-pin power connector to any available 3-pin power port (+/-15v DC & Ground), on any lower
console circuit board.
