The six inputs are 2-channel stereo, with four line level inputs using RCA jacks, one input on a 3.5mm TRS jack, and a Toslink digital optical input. A separate PA input allows you to override selected audio material and broadcast a single audio source to each connected zone. Additionally, a mute input allows you to mute each output channel using a single source trigger. Each output channel features an amplifier that is capable of delivering 50 watts/channel into a 4ohm load or 25 watts/channel into an 8-ohm load. Each amplifier can be individually bridged to produce 100 watts into an 8ohm load. The amp uses Euroblock connectors for the speaker level outputs, which takes less space than push-grip connector terminals. The Euroblock connectors can accept speaker wire up to 12AWG and can be removed from the amplifier for easier installation. Each output channel also features RCA line-level output jacks, allowing you to use a separate, more powerful amplifier in any output zone or to send
