[. . . ] (20) MASTER Master volume that controls output level to speakers. (21) POWER SWITCH (22) PROTECT LED indicator that lights on power up, power down, or whenever the FAULT DETECTION CIRCUITRY relays have disconnected the 1000RB from your speakers. (23) CLIP LED indicator that lights when the output is clipping. (24) POWER LED indicator that lights during normal operation. 4 Rear Panel Features Note : The block diagram of the 1000RB is printed on the rear panel and describes the signal flow from input to output. Many of your questions about the use and functions of the 1000RB are explained in this diagram. (25) FOOTSWITCH RF2 1/4'' stereo phone jack that connects to RF2, two button footswitch, via stereo cable. This jack is wired so that TUNING MUTE is controlled by the "tip", BOOST 2 is controlled by the "ring", and the "sleeve" is ground. (26) AUX IN 1/4'' phone jack that accepts a line level input. Can be used as an effects return in a "parallel" effects loop. (27) RETURN Accepts line level return from external effects that are connected in a "series loop" (such as limiters, enhancers, etc. ). Plugging into RETURN opens the connection between the 1000RB preamp and power amp stages. (28) SEND Line level output that is post EQ and pre BOOST. Used when sending a full range mono signal to an external device (effects or slave amp). (29) PRE/POST Select the source for the XLR balanced output(32). In the "out" position, the direct output is PRE meaning that it comes right off the input stage, (after TUNING MUTE, before VOLUME), and is unaffected by any front panel controls except the -10dB PAD switch. The PRE position is used to take a balanced direct output to the house PA in a live situation where the soundman wants a signal unaffected by your VOLUME and EQ controls. In the "in" position the balanced output is POST (comes from the last point in the preamp, just before the master volumes) and is affected by all the front panel controls. A POST balanced output can be used for recording. LEVEL Adjusts signal level of balanced output (32). (31) GND LIFT Ground lift switch that disconnects ground on balanced output (32) to eliminate hum. Out XLR connector with electronically balanced, low impedance output, used to send signal to P. A. Wiring for the XLR is "American Standard" : Pin 1 is ground, pin 2 is +, and pin 3 is-. [. . . ] MASTER Now that you have your basic tone, use the MASTER control to set your loudness(stage volume). A note regarding speaker cable: The 1000RB is capable of delivering more power than typical speaker cables can handle. We therefore recommend Speakon speaker cables. Choose cables that are compatible with the connectors on your speaker cabinets. These can be purchased through your G-K dealer. [. . . ]
