Operator Manual – SRA Series Amplifiers Page - 7

Typical Applications

The most common use of a SRA-Series amplifier is a 2-channel source driving 2 speaker

channels. In this illustration, the 4-channel amplifier is receiving two stereo signals and is

driving two pairs of stereo speakers The amplifier is in STEREO mode.

SRA-Series amplifiers are well suited to BRIDGED operation to drive a speaker load such

as a subwoofer or a more powerful stereo output on a 4-channel model. This illustration

shows a 4-channel SRA driving a Stereo signal in BRIDGED mode.

Connectors & Polarity

SRA-Series amplifiers utilize two types of professional audio connectors. For the inputs 3-

pin Euroblock connectors are utilized with their polarity clearly marked on the amplifier’s

rear panel. Outputs are via screw terminal connectors. The polarity for these connectors is

also clearly marked on the unit’s chassis. However, polarity changes when the unit is

operated in BRIDGED mode. Be sure to read the Operation section of this manual for

important information on the two operating modes.
