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. Like many precision components careful attention to the initial setup can yield dividends in higher performance and trouble-free use. "Operation" covers the controls and features of the amplifiers and how to use them to get the best effect. The "Technical Reference" section contains field service information. In addition to the schematic and parts list there are block diagrams and an explanation of circuit operation useful for technicians. We strongly urge reading over the Installation and Operation portions of this manual before putting the amplifier into service. The circuitry used in the P1500 and P3000 is the latest refinement of our trans·nova (TRANSconductance NOdal Voltage Amplifier, US Patent 4, 467, 288) circuit. It has been proven to offer sound quality to satisfy the most analytic audiophile or the most demanding professional. The natural sound and realistic reproduction have made trans·nova amplifiers preferred in many critical installations. Since our pioneering use of MOSFETs in the DH200 amplifier, they have proven extremely fault tolerant even in abusive situations. This sturdiness enables the amplifier to drive reactive speaker loads without the performance and sound penalties imposed by elaborate protection schemes. Specialized circuits prevent damage to the amplifiers and speakers without affecting the audio signal. A soft start circuit prevents sending potentially destructive turn-on and turn-off transients to the speakers. A thermal sensing network monitors the heatsink temperature and shuts down the amplifier to protect from excessive operating heat. [. . . ] Remove the two 9/64 Allen screws located between the heatsink fins along the top edge on each side, which fasten the cover. Three more screws hold the heatsink to the chassis; remove these screws and the level control knob. Unplug the gray cable which connects the mono input signal to Channel 2. Tilt the rear of the heatsink up and disengage the assembly from the chassis. [. . . ]
