A. LINE CORD - the Roc Pro 1000 is equipped with a grounding type supply cord to reduce the possibility
of shock hazard. Be sure to connect it to a grounded AC receptacle. DO NOT ALTER THE AC PLUG.
B. 8 OHM SPEAKER JACK (COMBO & HEAD MODELS) - Plug-in connection on rear panel for 8 ohm
speakers only.
C. 4-OHM ADDITIONAL SPEAKER JACK (HEAD MODEL ONLY) - Plug-in connection on rear panel for
4 ohm speakers or a second 8 Ohm speaker enclosure. The combined minimum impedance for all speaker
enclosures should be 4 ohms (i.e. two 8 ohm enclosures in parallel).
D. LINE OUT - This jack provides an output signal taken directly off the amplifier output and speaker and is
used for direct connection to recording and sound reinforcement equipment. Using a stereo cord in this
jack will provide a quasi-balanced signal. A mono cord will provide an unbalanced signal.
E. SEND - This unbalanced jack provides an output signal from the preamp and pre-reverb. It may be used
to drive effects units in an effects loop, to drive additional amplifiers in a multi-amp set up or as a preamp
send to a mixing console.
F. LEVEL SWITCH - This switch directly effects the Send (item E) jack by boosting or attenuating the signal
sent to the effects. External rack effects usually require -7dB or +4dB settings. Effects pedals usually
require a -16dB setting.
G. RETURN - This jack provides a return from your effects units and is pre-reverb. Plugging into this jack
activates the effects mix control (item Q). This jack can also be used as a power amp input.
