WHAT ELSE DISTINGUISHES THESE AMPLIFIERS? Constant power into varying impedances. It takes twice as much current to develop a given wattage into 2Ω as it does into 8Ω —but only half the voltage. Many amplifiers quote a high output current at 2Ω but have an unpublished operating time measured in a handful of seconds—before thermal shutdown (hopefully) precludes thermal meltdown. Our solution for this is selectable rail voltages for optimizing the amplifier to the load. This is impractical for con

Installation The SR2300/2800 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 SR2300/2800 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. Maximumoperating ambient temperature is 40°. The i

AUDIO GROUND CHASSIS/FLOAT SWITCH In general, the Audio Ground of each amplifier should be connected to AC mains earth ground AT ONE POINT ONLY- either through the Chassis (by selecting the "Chassis" position) OR through the input cable (with the switch in the "Float" position, and pin 1 of the XLR or the sleeve of the 1/4" connected to the ground of the signal source unit.) The Chassis/Float switch can be used as a means to troubleshoot ground loop problems, or to verify wiring. Ground loops ar

Operation The amplifier will operate with either a balanced or unbalanced signal source. INPUT The input jacks used on the SR2300/2800 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. To determine if your equipment is earth grounded or floated, consult the owner’s manual or test with an ohm- meter. The signal connections are as follows: XLR

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 equipment may already be connected to earth ground earlier in the audio chain, and it will typically be carried straight through to the output. It is also possible t

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. The load switch for each channel can be selected for the appropriate load, and the level controls can be adjusted individually for each channel. See diagrams

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. THERMAL Indicates when the thermal protection has shut down the amplifier. After cooling sufficiently, the amplifier will auto
