Page 10: Introduction
This manual contains information on using the P1500 and P3000 amplifiers. It is organized into three main sections. “Installation” covers the location and connection of the amplifier in the system. Like many precision components careful attention to the initial setup can yield dividends in higher performance and trouble-free use. -

Page 12: Installation
N S T A L L A T I O N 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. -
Page 13: Input
Pin 2 = (+) Pin 3 = (–) Many popular mixers use unbalanced outputs and can be used with the Hafler amplifier. To minimize residual ground noise, we recommend using twisted pair cable or short cable lengths in this type of configuration. - Page 14 C H E M A T I C I A G R A M P3000 shown.

Page 16: Output Connections
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. -
Page 17: Short Circuit Protection
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. In the event of a short in the speaker load or cables, the speaker detection circuit will shut down that channel and light the front panel SHORT indicator. -

Page 21: Technical Reference
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 use of lateral MOSFET output transistors and the low voltage trans• nova input stage combined with careful component selection for the circuit assembly made the reliability goals achievable. -

Page 23: Output Short Protection
Output Short Protection Drive Signal Output Signal The Short detector monitors the Drive Signal and Output Signal levels and shuts down that channel when a shorted output condition is detected. Recovering from the Short protection requires turning the amplifier off to reset. The comparator U4B monitors the Drive Signal and goes low when the drive level is sufficient to clip the output stage. -
Page 24: Clipping Indicator
To adjust the bias, disconnect the input and speakers and remove the jumper JW7. Connect an amp meter across the exposed pins. Adjust R136 to get a current reading of 100 mA for the P1500, 200 mA for the P3000. WARNING: Only a competent technician should attempt the following procedure. -
