Rolls RM70 User 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.
