  • Page 10: Introduction

    Introduction The Hafler GX2800 amplifiers are two rack height, two channel, fan-cooled professional power amplifiers suitable for use in the most demanding sound reinforcement and commercial sound installations. These amplifiers offer outstanding effi- ciency by means of three technologies: high-efficiency TRANS•nova Class-G circuitry, high-frequency switching power supplies, and constant power output/load impedance selection switches.

  • Page 11: Universal Line Voltage Input

    UNIVERSAL LINE VOLTAGE INPUT Voltage selection is provided in two bands: 100-140 volts and 200-265 volts, (both 50-60 Hz) via two quick-connect termi- nals located on the EMI filter board, accessed by removing the top cover. The current-mode control system automatically corrects for the bulk of power line variation with each band.

  • Page 14: Installation

    Installation The GX2800 is a standard 2U (2 rack height) 19" rack-mount unit, with both front and rear rack mounting ears. In portable systems, the amplifier must be supported at both the front and rear. COOLING The GX2800 uses forced-air cooling (fan cooling) to remove the heat produced during normal operation. Free air flow at the mounting location is a critical factor in accomplishing long-term reliable operation of the amplifier.

  • Page 15: Audio Ground Chassis/Float Switch

    • The chassis is permanently conected to the earth (safety) ground pin of the Mains power connector. • The Audio Ground of each GX2800 is permanently connected to the black terminals of both output binding posts, to pin 1 of each XLR input, and to the sleeve of each 1/4" input.

  • Page 16: Operation

    INPUT The input jacks used on the GX2800 are dual function connectors which accept 1/4" TRS (Tip Ring Sleeve) or male XLR plugs. The amplifier will operate with either a balanced or unbalanced signal, from earth ground or floated source equip- ment.

  • Page 17: Floated Source Equipment

    FLOATED EQUIPMENT Units with a 2-pin mains power cord have no means to connect the audio output ground to earth ground, so usually the audio output ground is floated from earth ground. However, this does not insure that when installed in a system, the audio output ground will remain floated from earth ground.

    Minimum gain position is marked as “Off” and represents over 100dB of attenuation relative to the maximum gain position. The CH B level control is used for all Bridged Mono configurations, and 100V and 70V modes (Except for GX2800 Dual 70V mode).each channel. See diagrams The Stereo/Biamp switch is defeated whenever the front panel Stereo/Mono switch is in the Mono position.

    70V and 100V Mono mode also use the CH B input connector and level control only. The 70V or 100V speaker array load should be connected across the red terminals of the output connectors. Set both load switches to the appropriate 70V or 100V value.
