'The S Zone is a professional quality 4-channel zone mixer that allows you to mix just about any audio signal including those from microphones, stereo CD and tape players, video players, and then lets you distribute an independent mix to any of the four stereo zones. Each of the input channels is assignable to any or all of 4 stereo zones outputs via easy to use, LED backlit switches. The microphone inputs can be set to 'duck" the zone inputs so that the background music automatically turns down when an announcement is made. On each the S Zone's outputs, you'll find a convenient two-band equalizer allowing you to adjust the overall tonal response of each zone. A six-segment LED bar VU meter is present on all outputs providing a visual display of the level of each zone. Perhaps the most unique feature of the S Zone is it's front panel monitor section. The zone assignment switch, headphone jack, level control and internal super speaker allow you to monitor the signal that is playing in any zone directly on the S Zone, without having to physically be in the room that signal is playing in. The handy scribe strip for both the inputs and outputs make it easy to label the connected gear and the rooms the S Zone is feeding. For easy installation, all the S Zone connections are made with standard Euroblock connection strips. SPECIFICATIONS: The S Zone has four stereo Input Channels with a Volume control, Stereo/Mono switch and dedicated Zone assignment switches. Channel 1 and Channel 2 inputs feature a high quality microphone pre-amp with phantom power allowing you to connect just about any dynamic or condenser microphone. The S Zone features four stereo Zone Outputs, each with a Stereo/Mono switch, Volume control, High and Low equalizers and a six-segment LED VU Meter monitoring the output level, enabling you to control the overall level and tone independently for four discreet coverage areas. A remote Volume Control for each Zone Output, up to 3000 feet in distance is possible using a standard 100k linear taper potentiometer and three-conductor shielded wire. Microphone 'Duck" switch on Channel 1 and Channel 2, which when turned on, allows any signal from the microphone inputs, like an announcement or page, to automatically lower the background music level. The S Zone features a unique front panel monitor section including a zone select switch, headphone jack, level control and internal super speaker allowing you to monitor the signal that is playing in any zone directly on the S Zone, without having to physically be in the room that the signal is playing in. Ultra-low noise circuitry with high quality op-amps ensure superb audio fidelity.
