The SR 2-125 Amplifier is purpose built to be the ideal companion for the SONARRAY SR1 satellite and subwoofer system. The SR 2-125 is a 125-watt stereo amplifier with DSP presets easily accessed through dials on the back of the amplifier. Whether the outdoor installation is hardscape or softscape, the amplifier presets optimize the best sound and performance of the SR1 system for any outdoor environment. The amplifier includes digital coax, toslink and analog inputs to accommodate all types of sources and streaming devices. Each input has a loop output allowing for the simple connection of multiple SR 2-125 amplifiers to power multiple SR1 landscape audio systems. The SR 2-125 can be rack mounted with the included rack ears or surface mounted with included feet. The SR 2-125 amplifier has analog, coax and toslink LINE INPUTS and loop OUTPUTS. The analog loop outputs are non buffered. The maximum number of amplifiers that can be looped together will depend on the output capability of your source component. The digital outputs are buffered and can support multiple amplifiers. Only one output can be used at a time.
