[. . . ] CIRCUIT BREAKER: The SVT-4 PRO employs an AC line circuit breaker to help protect against damages due to excessive current demands. If the amplifier stops working, check the circuit breaker. NOTE: When the circuit breaker opens, the button will be protruding and showing a contrasting color. You can reset the circuit breaker by pushing 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 with no signal input, have the amplifier checked by a qualified service person. AC LINE IN: Firmly insert the supplied AC power cord into this socket until it is fully seated. Plug the male end of the cord into a grounded AC outlet. DO NOT DEFEAT THE GROUND PRONG OF THE AC PLUG!AC OUTLET (Domestic units only): This unswitched outlet lets you connect any AC powered device (such as an effects unit or an electronic tuner) up to a maximum of 300 watts. The jack is "hot" whenever the amplifier is plugged into a live AC outlet, regardless of the setting of the amplifier's Power switch. SPEAKER OUTPUTS: The Speakon® Jacks: Use of these heavy-duty connectors is recommended when playing at full output levels. Connect the amplifier to your speaker cabinet(s) using heavy gauge speaker cables terminated with the appropriate connectors. (See text to left of jacks for pinout information. ) The 1/4" Jacks: These mono 1/4" jacks (two per channel, wired in parallel) offer you a convenient method of connecting the amplifier to your speaker(s) using cables terminated with 1/4" plugs. (Whenever playing at full output levels, it is recommended that you use the Speakon® jacks). 29 31 32. STEREO/MONO BRIDGE SWITCH: This switch sets the operating mode of the amplifier. In the "out" position the amplifier is in the Stereo Mode; with the switch in the "in" position the amplifier is in the Mono Bridged Mode. POWER AMP INPUTS: These jacks connect directly to the internal power amp for use with external preamps. When using external sources, connect the OUTPUT of the sources to these jacks using shielded instrument cables to feed the signals into the power amp sections. The internal signal is disconnected when a plug is inserted. In the Biamp Mode, Channel A = Low (frequency) Input, Channel B = High (frequency) Input. PREAMP OUTPUTS: These jacks are direct preamp outputs for use with external power amplifiers, mixing boards, external effects, etc. [. . . ] Asecond amplifier will be used to power the high frequency cabinet(s). The crossover point for the cabinets is determined by the Crossover Frequency control (#21). Depress the Stereo/Mono Bridge switch (Mono Bridge position) and connect the system as follows: SVT-4 PRO BIAMP HI OUT BIAMP LO OUT 2 POWER AMP A P. A.
