The Xantech SR21 IR Remote A/B Speaker Relay Module allows the user to switch the output of one stereo amplifier between two speaker pairs, or, to switch one speaker pair between the outputs of two stereo amplifiers. The switching is accomplished by way of infrared commands originating from a Xantech RC68+ Programmer. It can also be switched by a DC voltage applied between the CI (control input) and GND terminals. The RC68+ commands are "taught" to learning devices and passed to the IR IN and GND input terminals of the module via Xantech IR Receivers, Keypads and Connecting Blocks.
