Rolls RM67 Quick Start Manual

DIP SWITCH SETTINGS
- 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.
- Talkover switch 1 (T.O. 1), when in the down position, all program material on all
source inputs will be "ducked" or muted when a signal is present at Mic 1. NOTE: MIC
ONE WILL NOT TALK OVER MIC2 OR MIC3. ONLY THE SOURCE INPUTS WILL BE TALKED
OVER. This function is used for paging.
- Talkover switch 2 (T.O. 2), when in the down position, Source 1,2, and 3 will be
"ducked" or muted by the signals at Source 4.
This function is for jukebox priority. With a jukebox connected to Source input 4, 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.
- 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.
