– 8 – All measurements taken at Normal Operating Conditions (i.e. 1/8th rated output power) unless noted otherwise. POWER RA TING: 8 Ω 20-20kHz @ 0.1% THD 300W x 2 CH 600W x 2 CH 4 Ω 20-20kHz @ 0.2% THD 300W x 2 CH 600W x 2 CH 2 Ω 20-20kHz @ 0.
The Hafler GX2300 and GX2600 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.
– 10 – WHAT ELSE DISTINGUISHES THESE AMPLIFIERS? Constant power into varying impedance. It takes twice as much current to develop a given wattage into 2 Ω as it does into 8 Ω — but only half the voltage.
– 11 – 1. Recessed Front Panel - Prevents switches and controls from acci- dentally being adjusted or broken. 2. Power Switch - T urns the amplifier ON and OFF 3. Power LEDs - V erifies that the amplifier channel is ON 4. Status LEDs - Displays the status of the amplifier .
The GX2300/2600 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 GX2300/2600 uses forced-air cooling (fan cooling) to remove the heat produced during normal operation.
– 13 – AUDIO GROUND CHASSIS/FLOAT 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 GX2300/2600 are dual function connectors which accept 1 / 4 " TRS (T ip Ring Sleeve) or male XLR plugs.
– 15 – FLOATED SOURCE EQUIPMENT Source 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 – DELAY (One of these switches must be selected. If all the switches are OFF , there will be no output signal.) The delay feature provides five sections of 2nd-order all-pass delay filters of 450µsec +/-10µ sec each.
– 17 – LEVEL CONTROLS The gain for each channel can be controlled individually using the front panel level control. The controls have 32 detented positions that are calibrated in dB.
– 18 – LOAD SWITCH The Load Switch - located on the front panel - allows the amplifier power supply to be matched to the speaker load for more efficient, cooler running operation.This unique feature of the GX2300/2600 allows each channel to be configured for 2 Ω , 4 Ω , 8 Ω , or 70V , 100V mono operation.
– 19 – 1. Connect signal from source to both CH A and CH B inputs. 2. Move Stereo/Biamp 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.
– 20 – 1. Connect signal from source to CH B input. 2. Stereo/Biamp switch not active (Stereo/Mono switch overrides this switch when in mono/70V/100V mode).
– 21 – 1. Connect signal from source to CH B input. 2. Stereo/Biamp switch not active (Stereo/Mono switch overrides this switch when in mono/70V/100V mode).
– 22 – Hafler offers a limited warranty on Hafler products on the following terms: • Length of W arranty 5 years on GX2300 & GX2600 • What is Covered This warranty applies only to products sold to the original owner (non-transferable). This only applies to units sold in the Continental United States.
