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 commer cial sound installations.
– 9 – UNIVERSAL LINE VOL T AGE INPUT V oltage 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.

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.
– 13 – AUDIO GROUND CHASSIS/FLOA T SWITCH In general, the Audio Ground of each amplifier should be connected to AC mains earth ground A T ONE POINT ONL Y - either through the Chassis (by selecting.
– 14 – The amplifier will operate with either a balanced or unbalanced signal source. INPUT The input jacks used on the GX2800 are dual function connectors which accept 1/4" TRS (T ip 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.
– 15 – FLOA TED 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.
– 16 – PHASE The Phase switch will select either 0 ° (normal polarity) or 180 ° (inverted polarity) for the corresponding output signal. CD HORN EQUALIZA TION This adjustable high-frequency shelving circuit can be used to compensate for the roll-off of constant directivity (CD) horns.
– 17 – 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.
– 18 – 1. Connect signal from source to both CH A and CH B inputs. 2. Move Biamp/Stereo switch to Stereo input mode. 3. Move Stereo/Mono switch to Stereo mode. 4. Select desired speaker load (8 Ω /4 Ω /2 Ω ) for each channel – CH A & CH B loads do not need to match.
– 19 – 1. Connect signal from source to CH B input. 2. Biamp/Stereo switch not active-(Stereo/Mono switch overrides this switch when in mono/70V/100V mode). 3. Move Stereo/Mono switch to MONO mode. 4. Set load switches (8 Ω /4 Ω /2 Ω ) to 1/2 the actual load impedance.
1. Connect signal from source to CH B input. 2. Biamp/Stereo switch not active (Stereo/Mono switch overrides this switch when in mono/70V/100V mode). 3. Move Stereo/Mono switch to 100V mode. 4. Select 100V load, both channels. 5. Connect parallel array of 100V transformer -equipped speakers across the red terminals of the 5-way binding posts.
