NOTE: Descriptions for Channels 1 - 8 are identical.

TRIM: Adjusts the sensitivity of the XLR Microphone Inputs.

LEVEL: Adjusts the level of signal in the channel from off to +20 dB of gain. TONE:Cuts the signal up to 12 dB, below 200 Hz when turned clockwise, or above 6 kHz when turned counter-clockwise.

MASTER LEVEL: Adjusts the Main Output signal level.

pwr: LED indicating power is applied to the RM82.

Power Switch: Applies power to the unit. Please ensure the power cable is con- nected to a properly grounded AC outlet.

MAIN OUTPUT: XLR balanced jack containing the RM82 main output signal.

PRE-FADE OUTPUT: RCA jack for connection to another RM81 Aux/Bus Input or to another device such as a recorder.

AUX INPUT: RCA jack which connects directly to the RM81 mix bus. The jack may be connected to another RM81 Pre-Fade Output - making this unit the “Master”.

PHANTOM POWER SWITCHES: 8 individual DIP switches for applying 48 Volts of phantom power to the indicated channel’s XLR Input. The phantom power is for powering condenser microphones. The Phantom Power switches are in the OFF position when the RM82 is shipped from the factory.

CHANNEL INPUTS 1 - 8: 1/4” TS unbalanced, and XLR balanced input jacks. The eight 1/4” jacks come from the factory configured as line inputs and are electrically mixed with the XLR jacks. They may be used together if desired. These inputs may be reconfigured as either Direct Outputs, or Inserts. See page 4 for details.

A NOTE ABOUT ROLLS MICROPHONE PREAMPLIFIER CIRCUITS

The Rolls servo-balanced Microphone Preamps feature many advantages over other mic preamps. Among these are simplicity of design, 40db or higher CMRR (common mode rejection ratio) than transistor input mic preamps. This means much lower noise on long input lines, and very low distortion at high gain. Discrete transistor preamps are non-linear at high gains, but not our design. We feature a higher signal swing, which means our preamps have more headroom before clipping.
