The Hafler SR2300 and SR2600 amplifiers are two rack height, two channel, fan-cooled professional power amplifiers suit- able for use in the most demanding sound reinforcement and commer cial sound installations. These amplifiers offer out- standing efficiency by means of three technologies: high-efficiency TRANS • nova Class-G circuitry , high-f[...]

– 10 – WHAT ELSE DISTINGUISHES THESE AMPLIFIERS? Constant power into varying impedances. 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. Many amplifiers quote a high output current at 2 Ω but have an unpublished operating time measured in a handful of seconds — before[...]

Power LEDs - V erifies that the amplifier channel is ON 4. Status LEDs - Displays the status of the amplifier . The LEDs are as follows: SIGNAL indicates if signal is present; CLIP illu[...]

The SR2300/2600 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 SR2300/2600 uses forced-air cooling (fan cooling) to remove the heat produced during normal operation. Free air flow at the mounting loc[...]

– 13 – adapter plug for a two wire receptacle. The AC mains fuse is accessible at the rear panel of the amplifier . If this fuse blows replace it only with the same type and rating fuse. The correct replacement fuse value is printed on the rear of the amplifier , and on the specifications page. AUDIO GROUND CHASSIS/FLOAT SWITCH In general, the [...]

– 14 – The amplifier will operate with either a balanced or unbalanced signal source. INPUT The input jacks used on the SR2300/2600 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 equipment. T[...]

– 15 – 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. The input cable to this equ[...]

Biamp mode- 1 input signal and 2 output signals. Biamp mode is useful if a mono signal needs to be distributed to speakers of differing impedance [...]

– 17 – If the “ Protect ” LED is illuminated for prolonged periods during normal operation, select the next lower value Load Switch setting. Continue until the “ Protect ” LED ceases to illuminate, or lights infrequently . This switch can be safely operated while the amplifier is running. In 70V or 100V mode, the “ Protect ” LED ind[...]
