The Pass-Thru output provides a convenient source for daisy- chaining an additional amplifier without the need for extra RCA cables or “Y” adapters. The Pass-Thru signal is derived from summing the Front and Rear Left inputs to create a Left output, and summing the Front and Rear Right inputs to create a Right output. When the amplifier is used with 4-channel inputs, the Pass-Thru provides constant output regardless of the source unit fade position. Additionally, the Pass-Thru has an XCard that can be set for High-Pass,Low-Pass or Full Range.
THE RESULT: Constant non-faded output for adding woofer amplifiers.
