CONNECTION
Inputs
Connect low impedance microphones to the Mic XLR inputs. If a paging microphone is be-
ing used, connect it to Mic Input 1 so it may be used with the Talk Over function. Connect
source signals such as CD players, cassette players or video players to the RCA Source
Inputs. If a jukebox is being connected, and you want its signal to mute the other source
signals, connect it to Source input 3.
Output
Connect a stereo RCA cabe to the main Output jack, and to an amplifi er or the next device
in your signal chain.
Shown here is a connection
example for the MX152.
OPERATION
DIP SWITCH SETTINGS (From left to right)
• The Mono/Stereo switch selects the output mode. When the switch is up, the unit is in
stereo mode. When the switch is down, the stereo signals are mixed to mono and sent to
both the Right and Left Main output jacks. Either jack can be used as a mono output.
• Source 3 Priority: when in the down position, Source 1,and 2 will be “ducked” or muted
by the signals at Source 3.
This function is for jukebox priority. With a jukebox connected to Source input 3, and the
Talkover switch 2 on (down), the other Source input signals such as background music,
will be muted and only the jukebox will be heard.
• Mic 1 Priority; when in the down position, all program material on Mic 2, Source 1 and
2 inputs will be “ducked” or muted when a signal is present at Mic 1. Source 3 is left un-
muted. This function is used for paging.
• Source 3 Mono; this switch sums the Right and Left inputs of Source 3 to a mono signal.
• If a microphone requires phantom power, move the Mic channel’s corresponding PHAN
DIP switch to the down position. This applies 12 volts dc phantom power to the indicated
microphone.
