[. . . ] Products returned to us or to an authorized Service Center must be accompanied by a copy of the purchase receipt. In the absence of such purchase receipt, the warranty period shall be one (1) year from the date of manufacture. This warranty shall be invalid if the product is damaged as a result of defacement, misuse, abuse, neglect, accident, destruction or alteration of the serial number, improper electrical voltages or currents, repair, alteration or maintenance by any person or party other than our own service facility or an authorized Service Center, or any use violative of instructions furnished by us. This one-year warranty is in lieu of all expressed warranties, obligations 1 or liabilities. [. . . ] RATIO: This control sets the signal to compression ratio. 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. GAIN REDUCTION: VU Meter indicating the amount of compression in dB. NOTE: THIS METER DOES NOT INDICATE INPUT OR OUTPUT LEVEL. 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. This sweepable filter has a Q or width of 1. 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. OUTPUT LEVEL: Adjusts the overall volume from the RP503 main outputs. 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. Side Chain 1. 75" x 6" x 19" (90mm X 162mm X 482mm) 3. 5 lbs. (1. 75 Kg) 120VAC (230VAC) 15VA Input/Output jacks Dimensions Weight Power 5 2 DESCRIPTION CONT. 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. Connect to an audio recorder line input or mixer line input. Note: Do not connect the RP503 XLR Output to a mixer's Mic Input - it will overload that input. SIDE CHAIN: 1/4" Tip-Ring-Sleeve Send\Return jack. Connect an Insert cable to this jack and to a signal processor or other device to alter the action of the RP503 compressor. [. . . ] The 1/4" SEND plug connects to the Input of a signal processor such as an equalizer, the 1/4" RETURN plug connects to the signal processor Output. The signal in the SIDE CHAIN is not heard on the Output of the RP503, it only effects the action of the compressor. 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. [. . . ]
