CHQ-DSC2 (SCI) SIL, SIL2 standard 2-output audio control module
Model CHQ-DSC2 (SCI) / SIL is a dual audio driver, designed to provide two audio outputs (which can be controlled separately) with full error monitoring Monitored inputs monitor can be used for local power failure monitoring or as a general purpose input Unit uses simple DIL switches for reliable addressing A rear box is also available (CHQ-BACKBOX), when used in conjunction with CHQ-DSC2 (SCI)/SIL, increases the IP rating to IP level.
