Randall RG-60 2 RB-60 — OWNERS MANUAL ©) RB-60 © OO DUAL FUNCTION INPUT JACKS: INPUT No.l 6dB greater than Input No.2 INPUT No.2 Reduced gain to accomodate extra-strong signals VOLUME CONTROL To regulate input gain REVERB CONTROL To regulate built-in circuitry. Reverb can be turned on and off by means of a footswitch. (See rear panel highlights). TREBLE CONTROL MIDDLE CONTROL (On RB-60 only--to provide added tonal control for bass instruments.) BASS CONTROL Note: Since no one can determine exactly what sound will be desired in all instances, it is best to experiment with the tone controls to produce the desired response, If all tone controls are set at O there will be no sound! MASTER SUSTAIN A Master Sustain Control is provided for added flexibility. For a clean sound the Master Sustain Control should be set at 10 while using the Volume Control to achieve the desired volume level. For an overload-like sustain sound, the Master Sustain Control should be at a relatively low setting such as "5". The Volume Control should then be set for the desired sound. The Master Sustain can then be used to raise or lower the overall volume level. By experimenting with both settings you should be able to achieve any sound from studio clean to rock and roll dirty. PILOT LIGHT - POWER POLARITY SWITCH Three position switch provides a means of turning amplifier on and also reversing poxer potarity. CIRCUIT BREAXER The Circuit Breaker 1s actually a mechanical fuse and protects the amplifier from extreme overload conditions. Pushing in on the Red Circuit Breaker Button will set it. If the Circuit Breaker does trip and cannot be reset, refer to a qualified technician. FOOTSWITCH JACK ON RG-60 ror hands-free, on-off operation of Reverb. EXTERNAL SPEAKER JACK Provided to connect an external speaker of 8 ohms. PRE-AMP OUTPUT JACK Provided to supply signal for driving additional amplifiers or for direct recording. SERIAL NUMBER Be sure to send in your Warranty Card.
