The AVC4 is two AVC2s in a single 1U case, for venues that need to hold two stereo systems to their own limits, such as a main room and a bar, or a dance floor and a dining area. Each channel works exactly like an AVC2: it has no effect below its threshold and above it fades the output down in steps, working on average level so the music keeps its dynamics. Each stereo channel is set independently with its own two levels, and everything is sealed behind the supplied tamper-proof cover.
