Rolls RM70 - Manual

The RM70 is a single rack space mixer designed for the install/contractor market. It
is ideal for small clubs, restaurants, churches, or schools. The unit mixes three bal-
anced microphones with five stereo sources to mono or stereo balanced Main Out-
puts.
The XLR Microphone Inputs have Mic/Line level switches, a Mic/Loop Insert jack,
and individually switchable +12 VDC phantom power. Priority talkover is available
on one microphone for paging. When this function is engaged, the signal at Mic One
temporarily mutes the source signals - the other two mic signals are still present.
A Music-On-Hold function has been included for connection to an telephone
system. The signal present at Source 3 Input will be sent to the Music On Hold screw
terminal outputs. A Music On Hold level control has been provided to adjust the
volume of this function.
Each Microphone input has a level and tone control, and Bass and Treble controls
have been provided for all the sources. A Master Output Level control adjusts the level
of all mixed signals.
A Remote Volume output jack is provided for connection to a 100K ohm linear
taper potentiometer and used as an external master level control.
