IS-MIX1
Issued: 6-1-14
The MIX1 “MAIN” output connection is an RCA phono jack. The connecting output cable should
be wired with the pin “hot” or “+” and with the sleeve “common” or “-”. The main output jack is
fed after the master volume control and low cut filter.

PHANTOM POWER
The microphone inputs on the MIX1 do not provide phantom power for condenser microphones. An external
phantom power supply (sold by others) may be used to provide phantom power to a condenser microphone before
feeding the signal to the MIX1 microphone input.
Microphones may be connected to the three (3) screw terminals for the “MIC” input of channel 1 through channel 6.
Note: the input channel chosen will depend on the muting scheme chosen. For example: If the microphone will
have the highest priority and will mute all other channels, connect to the channel 1
“MIC” input and set the “MUTE”
switch to “2-8”. If the microphone will be a lower level priority and will be muted by an input fed to channel 1,
choose the microphone input on channel 2-6.

If the 600
W balanced page port output is a line level output and is not adjustable, it is best to use the Lowell
TLM-600 matching transformer (or any other 600
W balanced to high impedance unbalanced telephone
transformer adaptor) and feed the telephone page input to the channel 1 Aux input RCA jack (as shown below).
Note: The MIX1 muting priority for channel 1 is still functional when using the Aux input RCA jack to feed the
paging input to channel 1.

TELEPHONE INPUT WIRING
The page port output from a telephone system will be a 600
W balanced line level output. If the telephone page
port output can be reduced to a microphone level, it is possible to connect the telephone page feed to the
channel 1
“MIC” input of the MIX1 (as shown below) .
