  • Page 11: Introduction

    WEIGHT: Introduction 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 commercial sound installations. These amplifiers offer out- standing efficiency by means of three technologies: high-efficiency TRANS•nova Class-G circuitry, high-frequency switch- ing power supplies, and constant power output/load impedance selection switches.

  • Page 12: What Else Distinguishes These Amplifiers

    WHAT ELSE DISTINGUISHES THESE AMPLIFIERS? Constant power into varying impedances. It takes twice as much current to develop a given wattage into 2 as it does into 8 —but only half the voltage. Many amplifiers quote a high output current at 2 but have an unpublished operating time measured in a handful of seconds—before thermal shutdown (hopefully) precludes thermal meltdown.

  • Page 14: Installation

    Installation 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 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 SR2300/SR2600 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 SR2300/2600 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 equipment.

  • Page 17: Floated Equipment

    GROUNDED, UNBALANCED SOURCE 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.

    70V mode). BIAMP/STEREO SWITCH Turn amplifier off before operating this switch. This switch is located on the rear panel and selects either: Stereo mode- 2 input signals and 2 output signals. 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 or power level.

  • Page 19: Thermal

    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 indicates there are too many speakers loading the array.
