User manual ROLLS RP503

[. . . ] FEATURES · Warm tube mic preamp with +48 volt phantom power and CLIP indication · Smooth and natural optical compression with VU gain reduction meter · Side Chain I/O for detector circuit access · Three-band EQ with sweepable mids INSPECTION 1. If obvious physical damage is noticed, contact the carrier immediately to make a damage claim. We suggest saving the shipping carton and packing materials for safely transporting the unit in the future. Please complete the Warranty Registration Card and return it to the factory. [. . . ] PHASE REVERSE: When pressed in, the output signal will be 180 degrees out of phase with the input signal. PHANTOM POWER: When pressed in, and the LED above this switch is lit, +48 volts of phantom power is applied to the XLR Mic input. CLIP: LED for indicating clipping or possible distortion in the mic preamp circuits. Compressor controls IN/OUT: Switch for engaging the compressor circuits. THRESHOLD: Sets the point that the input signal must reach for compression to begin. This ratio relates to the amount of increase of input compared to output signal. Thus, at a 1:1 ratio, a 1 dB increase of input signal will result in a 1 dB increase of output signal. At 2:1, a 2 dB increase of input signal will result in only 1 dB increase of output signal. At 8:1, an 8 dB increase of input signal will result in a 1dB increase of output signal. Equalizer controls LOW LEVEL: Adjusts level of low frequencies, from 20Hz to 150Hz. MID LEVEL: Adjusts the level of mid frequencies, as selected by the MID FREQUENCY control. MID FREQUENCY: Selects the frequency to be boost/cut by the MID LEVEL control. HIGH LEVEL: Adjusts the level of high frequencies, from 10kHz to 20kHz. PWR LED: Indicates power is applied to the RP503. -30 dB to +20 dB 2:1 to 8:1 Phantom Power LED, Clip LED, Power LED Analog VU Meter XLR balanced 1/4" unbalanced 1/4" TRS unbal.

OPERATION When the RP503 has been properly connected, ensure the power switch is on and the Power LED is lit. REAR PANEL 120 VAC 50/60 Hz: OUTPUT: 1/4" unbalanced and XLR balanced output. Note: Do not connect the RP503 XLR Output to a mixer's Mic Input - it will overload that input. Connect an Insert cable to this jack and to a signal processor or other device to alter the action of the RP503 compressor. Connect balanced microphones to the XLR input, and unbalanced instruments to the 1/4" input. CONNECTION Make sure the RP503 power cord is properly connected to a grounded AC outlet. [. . . ] The higher the level of signal in the SIDE CHAIN, the more compression will occur. EQUALIZER SETTINGS Begin with all controls set at 0 or center detente position. Adjusting the LEVEL controls will increase or decrease the amount of the indicated frequency range. The MID FREQUENCY control adjusts the actual frequency that the MID LEVEL control will adjust.
