15.CIRCUIT BREAKER: The B500DR employs an AC line cir- cuit breaker to help protect against damage due to excessive current demands. If the amplifier stops working, check the circuit breaker. If it has opened, the button will be protruding and show- ing a contrasting color. You can reset the circuit breaker by push- ing it in until it latches. The breaker must cool down for a short time before the button will latch. If the circuit breaker opens repeatedly, have the amplifier checked by a qualified service per- son.
16.AC LINE IN: Firmly insert the supplied AC power cord into this socket until it is fully seated. This grounded power cord is to be plugged into a grounded power outlet, wired to current elec- tric codes and compatible with voltage, power, and frequency requirements stated on the rear panel. Do no attempt to defeat the safety ground connection.
17.SPEAKER OUTPUTS: The 1/4” jacks offer a convenient method of connecting to speaker cabinets using cables terminat- ed with 1/4” plugs. However, when using the amplifier at or near its full output power, using the Speakon® jack is recommended.
18.FOOTSWITCH: Use this jack to connect the Ampeg AFP4BD four button footswitch to the amplifier for remote selection of the four presets.
19.BALANCED LINE OUT: Use this jack to send a
20.LEVEL: Use this control to adjust the level of the signal at the Balanced Line Out jack (#19).
21.POWER AMP INPUT: Use this jack to connect the output of an external preamp directly into the power amp circuitry of the B500DR by means of a shielded signal cable. The preamp sig- nal is disengaged when this jack is used.
22.PREAMP OUTPUT: Use this jack to send a preamp signal to an external power amplifier, mixing board, external effects, etc. by means of a shielded instrument cable. Using this output does not break the connection to the internal power amplifier.
23.PRE/POST: This switch, when depressed, sends a
24.EFFECTS LOOP RETURN: Use this jack to connect the B500DR to the output of an external effects device by means of a shielded signal cable.
27.EFFECTS LOOP SEND: Use this jack to connect the B500DR to the input of an external effects device by means of a shielded signal cable.
