And to maintain the optimum operating temperature, WP-1200 and WP-1400 features the newly developed servo cooling system which is constantly adjusted the fan speed regardless of output level. Speaker safety is further assured by CROW-BAR circuitry which operates when DC voltage is generated at the output terminals due to amplifier malfunction. FEATURES • The WP-1200, WP-1400 are 2-channel power amplifiers providing continuous outputs of 200W (RMS) + 200W (RMS) [WP-1200), 400W (RMS) + 400W [RMS] [WP-1400] (THD 0.3*/. or less with 4-ohm load, 40 Hz to 20 KHz). At 0-ohm load : 120W (RMS) + 120W (RMS) [WP-1200], 240W (RMS) + 240W (RMS) [WP-1400] continuous output (THD 0.3’/, or less with 0-ohm load, 20 Hz to 20 KHz) can be obtained. • In bridge mono mode the power amplifier provides a 400W (RMS) [WP-1200], 0OOW (RMS) [WP-1400] output (THD 0.3/. or less for 8-ohm load, 20 Hz to 20 KHz). • The input circuit is electronically balanced employing an operational amplifier of excellent transient response and wide bandwidth. As a result, deterioration of response caused by the transformer and the effects of induction noise are minimized. • Two types of input connectors are provided XLR type connectors (female) and 1/4’ TRS phone jacks. • The amplifier is protected by a Vl-type energy limiter (voltage/current sensing protection circuit) that limits the current in the event of a short circuit and cuts off the output in the event of malfunction such as overheating or DC. • The muting circuit prevents switching noise caused by turning the amplifier on or off. • Input level adjustment controls are provided on each channel. • 5 way binding posts are provided as output terminals. These posts are evenly-spaced, enabling the use of dual-banana plugs for either individual channel output, or bridge mode. • A ventilation fan prevents the amplifier from overheating when properly installed. • These amplifiers are power efficient due to the Class H power output circuit. • Output terminal CROW-BAR DC detection circuit protects the speakers. • Front-panel LED's indicate peak signal and protect mode. • The automatic fan control circuit varies the fan speed as needed by sensing the temperature of the heat sink and the power transformer. PRECAUTIONS • Do not stand the amplifier vertically on its back. • Due to the muting circuit, no sound is produced for 4 to 6 seconds after turning on the power supply. • Always use a power source of adequate capacity. • Do not turn on the power of multiple power amplifiers at the same time. Never allow the ventilation holes on the Front and Rear of the amplifier to get obstructed in any way. • To clean the amplifier, wipe it with a dry cloth. If the case is very dirty, disconnect the AC cord from the power source, then wipe it with a cloth dampened in water or mild soapy water, then wipe dry thoroughly. Never use solvents or chemical cloth, similarly, never spray insecticides as they may cause discoloration or peeling. • If any trouble is found, disconnect the power cord and contact your dealer. - 2 - MAJOR OPERATING CONTROLS AND THEIR FUNCTIONS ■ WP-1200 • Front Panel: ■ WP-1400 • Front Panel: 1. Power ON/OFF switch [POWER] • The power amplifier reaches the operating conditions 4 to 6 seconds after turning on the power ON/OFF switch due to a muting circuit which prevents switching noise at power-up. CAUTION : When using the WP-1200/1400 in a system with other equipment such as a mixer, equalizer, and other signal processor, always turn the amplifier on last as switching noise from the other equipment can damage the speakers. Similarly, at system power-down always turn the amplifier off first. • Rear Panel: 2. Peak level Indicator [PEAK (r...
