INTRODUCTION The Hafler P1500 and P3000 are two channel professional power amplifiers. Passive cooling with large heatsinks is used for low mechanical noise. Our patented trans•nova circuit topology and MOSFET output stage ensures trouble free, long term operation and is backed by our five year warranty. 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.

INSTALLATION 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. The amplifiers can also produce considerable heat in normal operation so the primary consideration when determining a location for the amplifiers is to allow for adequate ventilation.
INPUT The input jacks located on the back of the amplifier are dual function connectors which accept 1/4" Phone (Tip Ring Sleeve) or XLR plugs. The 1/4" Phone jack is connected according to conventional usage. The XLR jack is connected according to the IEC and AES standard.
SCHEMATIC DIAGRAM P3000 shown. Ground switch in Chassis position, Mono switch in 2-Channel position. P1500 differences shown on parts list.
Removable Center Spread
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. To bridge the amplifier, set the rear panel Mono/2 Channel switch to the Mono position.
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.

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.

Output Short Protection Drive Signal Clip Detector U3A Shut Down Switch Q5, Q4 Comparator U3B Clip Detector U4A Short Latch U4C, CR14 Short Indicator CR1 Comparator U4A 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.
Clipping Indicator Drive Signal Clipping Detector U5A LED Driver U5C CLIP Indicator CR3 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. The reference voltage scales the output of U5A to indicate when the Drive Signal at pin 6 demands in excess of the available voltage or current of the output stage.
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. Turn the amplifier level controls full down and turn the amplifier on. Turn up the level control until you hear a signal through the speaker. Alternate adjusting R8 and the input control until you have the level control full.
