Accessory 28-volt DC: To convert to dc operation, this jack is used as a power input when using the Model A68B Battery Power Supply (Accessory). When not using the mixer turn off the switch to conserve battery life (pilot light does not operate when using A68B). Grounding If there should be objectionable hum, connect the metal chassis of the mixer to a good ground such as a metal frame of a wall outlet or a water or steam pipe. This is normally accomplished automatically through the ground wire of the power cord. Reverberation The red control knob (on front panel) marked RE- VERBERATION is used to adjust the amount of rever- beration to the desired effect. The standard phone jack (on back panel marked REVERBERATION REMOTE SWITCH) is used to con- nect an On-Off switch which can be operated through a single-conductor shielded cable at a remote location to turn reverberation on and off. See Figure B for switch connections. CONDUCTOR o TIP r SLEEVE 1 SHIELD PHONE PLUG SWITCH REMOTE REVERBERATION SWITCH FIGURE B CAUTION: The PE70RM Reverberation Mixer should not be set on or mounted against a loudspeaker, as vibrations from the speaker cabinet may cause im- proper operation of reverb. Avoid accidental jarring during operation. Interconnecting Two Units 1. A PE70RM Reverberation Mixer and a Shure PE68M five-channel Mixer may be combined to give a total of eight microphone/instrument channels. In this case, four channels could have reverberation and four channels would NOT have reverberation. Unit 1 is the PE70RM, and Unit 2 is the PE68M. A. Connect GUITAR AMP. OUTPUT on Unit 1 to fifth MICROPHONE/INSTRUMENT INPUT on Unit 2. B. Connect microphones or instruments to mixers and set each input control to #O position. C. Take output signal for desired application from appropriate output jack on Unit 2. D. Set Master Control on Unit 1 to position #4. E. Set fifth MICROPHONE/INSTRUMENT INPUT Control on Unit 2 to position #lo. F. Master Control on Unit 2 is now Master for all inputs. G. Advance Master Control (Unit 2) to about #5 position and adjust individual microphone con- trols for proper level. If overall gain is too low or too high, Master Control (Unit 2) may be adjusted. A PE70RM Reverberation Mixer and a Shure PE68M five-channel Mixer may, also, be combined to permit reverberation in all eight microphone/instrument channels. In this case, Unit 1 is the PE68M, and Unit 2 is the PE70RM. A. Connect GUITAR AMP. OUTPUT on Unit 1 to the fourth MICROPHONE/INSTRUMENT INPUT on Unit 2. B. Connect microphones or instruments to mixers and set each input control to #O position. C. Take output signal for desired application from appropriate output jack on Unit 2. D. Set Master Control on Unit 1 to position #4. E. Set fourth MICROPHONE/INSTRUMENT INPUT Control on Unit 2 to position #lo. F. Master Control on Unit 2 is now Master for all inputs. G. Advance Master Control (Unit 2) to about #5 position and adjust individual microphone con- trols for proper level. If overall gain is too low or too high, Master Control (Unit 2) may be adjusted.
