LOCATION The P1500 and P3000 power transformer can generate a substantial magnetic field, so caution should be exercised in the placement of low level components such as a tape deck, mixer or mic preamp to avoid inducing noise in the low level circuitry.

– 7 – OUTPUT CONNECTIONS The speaker output connectors are dual binding posts. These binding posts will directly accept 12 AWG wire or banana plugs and are spaced on 3/4" centers to accept dual banana plugs. MONOPHONIC USE For systems with high power requirements, the amplifiers can be configured for single channel bridged mono operation.
SHORT CIRCUIT PROTECTION Due to the self-protecting properties of the output power MOSFETs, there is no need for sonically degrading voltage and current limiting circuits. To protect the amplifier from problems which may occur in the speaker line there is an overload detection circuit.

T ECHNICAL R EFERENCE FIELD SERVICE CONSIDERATIONS A primary focus during the design and development of the P1500 and P3000 was to ensure the dependability of the amplifiers.
The transistor Q1 is configured to operate as a switch which controls the current source, Q103, of the input differential amp, Q6 and Q7. When Q1 is off, the emitter voltage is low turning off Q103. Timing of the Soft Start function is controlled by the charging time of C29.
Output Short Protection The Short detector monitors the Drive Signal and Output Signal levels and shuts down that channel when a shorted output condition is detected.
CLIP Indicator CR3 LED Driver U5C Clipping Detector U5A Drive Signal Clipping Indicator The CLIP indicator is driven by the buffer U5C which is controlled by the comparator U5A. The voltage divider R56 and R57 establishes the reference voltage for the Clipping detector at pin 7 of U5A.
amplifier. For a temporary adjustment when a signal generator and voltmeter are not available, use an FM tuner and tune it to an unused station as your signal source, and connect the output to the amplifier as described above. Connect the amplifier output to a small full range speaker.
