Precautions 1. Power Supply Unit (RPS-7) The RPS-7 is separate from the console. If the power switch on the RPS-7 is turned "on" without a connection between the RPS-7 and the board using the accessory cable packed in the RPS-7, power is not supplied to the board. The power switch must be "on" after the connection is made. 2. Power Supply The RPS-7 is designed to operate on local AC (50/60Hz) mains, ±10%. 3. Fuse Replacement The front panel of the RPS-7 is provided with a fuse holder for the AC

Features INPUT MODULE 1. Phantom Power ON/OFF switch. 2. TRIM gain control offers extremely convenient operation when used in conjunction with INPUT LEVEL switch. 3. MID-EQ is peaking equalization, and its center frequency can be set by a continuously variable frequency control knob. 4. Two foldback control knobs for the 2 foldback busses. One is Pre-fader and the other is associated with the PRE-POST selector switch for additional effects. 5. Two echo control knobs for the 2 echo busses. One is

PROGRAM MODULE 1. Group 1, 2, 3 and 4 controls pick up the signal from the four group out busses and assign them to the program output. The program output is therefore suitable for feeding the signal to the house sound system. 2. Program On/Off pushbutton determines whether the individual program output signal is to be fed to the rest of the sound system or other equipment. 3. Peak indicator for detecting overload condition. 4. Program channel mixed signal can be monitored through headphones by

Input Module (IPM-7) 1. XLR type INPUT connector is balanced, transformer-isolated and accepts low impedance sources from -60dB to +10dB. Proper adjustment of both the INPUT LEVEL Switch and TRIM Knob make it possible to provide the optimum setting for each input. 2. GROUND (GND) LIFT Switch is for Pin 1, which makes it easy to avoid ground loops that are often caused in connection with other equipment and that may induce hum noise. Sliding the ground lift switch from the NORMAL position to the

13. Echo knobs provide for two independent echo mixes. The No. 1 echo knob mixes the signal post-fader, but the No. 2 echo knob is associated with the Pre-Post fader selector switch. 14. PAN POT adjusts the relative output level (balance) to the four mixing busses. It is operated in conjunction with the group assign pushbuttons to put the desired level of output signal adjusted by the pan pot onto the mixing busses selected by the group assign pushbuttons. Any selection of the four group assign

Group/Foldback Module (GFM-7) 1. AUX INPUT connector (XLR type) is balanced, transformer-isolated. The nominal level and impedance are +4dB and 600 ohms respectively. 2. GROUND (GND) LIFT switch is for pin 1, which is used to avoid ground loops that are often caused in connection with other equipment and that may induce hum. Sliding the ground lift switch from the NORMAL position to the LIFT position cuts ground loops and may reduce hum. For most applications it should be set to the NORMAL posit

Group/Echo Module (GEM-7) 1. ECHO IN connector (XLR type) is balanced, transformer-isolated. The nominal level and impedance are +4dB and 600 ohms, respectively. 2. GROUND (GND) LIFT Switch is for pin 1, which is used to avoid ground loops that are often caused in connection with other equipment and that may induce hum. Sliding the ground lift switch from the NORMAL position to the LIFT position cuts ground loops and may reduce hum. For most applications it should be set to the NORMAL position.

Program Module (PGM-7) Each program module incorporates two program output channels (programs A and B) and each program channel can be controlled independently. 1. PROGRAM OUTPUT B connector (XLR type) is balanced, transformer-isolated. The nominal level and impedance are +4dB and 600 ohms, respectively. The program output B signal is derived from one of the four group out busses. 2. GROUND (GND) LIFT switch is for pin 1, which is used to avoid ground loops that are often caused in connection wi
