Page 16

Operation

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 (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 Balanced

1/4" TRS Balanced

1/4" Mono Unbalanced

DAISY CHAIN OUTPUT

Proper cable wiring will be determined by the source equipment that is feeding signal to the amplifier.

EARTH GROUNDED SOURCE EQUIPMENT

Source Units with a 3-pin mains power cord will typically have the audio output ground connected to the earth-grounded chassis. This can be verified with an ohmmeter by disconnecting the mains power cord from the AC outlet and checking for continuity between the earth ground pin and the audio output ground. This test should be done with the equipment installed in the complete system, including cables. If the audio output ground is connected to the earth ground pin, it is

earth grounded equipment.
