  • Page 5: Introduction

    This manual contains information on using the 9505 amplifier and 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.

    Fan center approximately in line with edge of unit and starting of heatsink fins AC LINE The 9505 amplifier operates from a 120 volt, 60Hz AC power line. Connection is made by a 16 gauge, IEC Type 320, grounded line cord. For safety considerations only a properly grounded (earthed) receptacle should be used.

    UNBALANCED INPUT The unbalanced inputs use conventional RCA phone jacks. Set the BALANCED/UNBALANCED switch to the UNBALANCED position to use these jacks. BALANCED 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.

    When the amplifier is bridged the output is floating. Any speaker which requires a common ground from the amplifier output cannot be used in this application. Cuando el amplificador esté en modo puente (bridge), la salida del mismo es flotante (sin neutro). Cualquier parlante que necesite una tierra común de la salida del amplificador, no puede ser usado cuando el modo puente esté...

    LOAD FAULT PROTECTION Because of the self-protecting properties and fault tolerance of the lateral MOSFETs used in the 9505, elaborate voltage and current limiting protection schemes are not necessary.

    (voltage-to-current converter). The 9505 is the most sophisticated amplifier we have yet developed utilizing the basic trans• nova principle. And, although the measured specifications are very good, the numbers do not describe the realistic sound of the amplifiers.

  • Page 18: Calibration

    The final output stage utilizes lateral MOSFETs; four pairs are used for each channel in the 9505. These devices, unlike conventional bipolar transistors do not exhibit “thermal runaway.” Thermal runaway is a phenomenon whereby a transistor heats up as it draws more current, which causes it to get hotter, and conduct more current, and so on until the device self destructs.
