REFER SERVICING TO QUALIFIED SERVICE PERSONNEL RISQUE DE CHOC - NE PAS ENLEVER 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. 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 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. These inputs may be reconfigured as either Direct Outputs, or Inserts. See page 4 for details. 5 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. 2 CONNECTION 1. MICROPHONE AND MAIN OUTPUT CONNECTION Connect microphones to the XLR Inputs as shown here. [. . . ] Connect a 1/4" unbalanced TipSleeve cable to the channel's 1/4" jack and to the next device you want the signal sent to. Note, the channel's signal will still be present at the RM82 Main Output. SERIAL NUMBER 82PREFADE OUT CHANNEL 8 CHANNEL 7 MODEL RM82 PHANTOM POWER CONFIGURING THE OUTPUT FOR MIC OR LINE LEVEL The RM82 ships from the factory with the XLR Main Output configured as Line Level (+4 dB). To change this to Mic Level (-10 dB), carefully remove the lid, locate the Mic/Line header which is near the Main Output jack. Move the two jumpers from the Line Level position (shown below on the right), to the Mic Level position (shown on the left). 120 VAC 50/60 Hz 15 VA MADE IN U. S.
