Product Description
The Audica MULTIzone 4 - Channel System Controller is a top - notch zone control mixer. It features 4 zones with 6 music inputs and a microphone input for paging. Each of the 4 outputs can be independently configured to play music from any input, along with the paging microphone. Front - panel controls allow you to set relative levels easily. When announcements are made, the music level is automatically reduced for clear hearing. All zone outputs are mono, while inputs are stereo - capable and mixed to mono internally. You can choose between flat response or Audica loudspeaker EQ for zone outputs. A mute control input links to fire control systems, muting music inputs but keeping the paging microphone active. Remote zone control is available via wired panels or an RS232 interface, and up to 7 units can be daisy - chained for up to 28 zones. Each zone has independent controls on the front panel. Rotary switches select the input, and rotary controls set the music level. A separate rotary control adjusts the microphone mix. The music attenuation when the microphone is active is adjustable on the rear panel. Inputs have independent gain controls to match source levels and optimize the signal - to - noise ratio. The microphone input has a wide gain range and can also be used as a line - level input. For fire safety, the unit offers two types of inputs: isolated contacts or a voltage input. The RS232 control port enables control from a PC or other systems, providing great flexibility in system configuration. Technical specifications include various input and output connectors, front and rear panel controls, and useful indicators.
Using the Audica MULTIzone 4 - Channel System Controller is quite straightforward. First, connect your music sources to the stereo phono jacks or the XLR input for the paging microphone. You can also loop the audio inputs to other units using the 15 - pin D - Type connector. On the front panel, use the power switch to turn on the unit. Then, for each zone, select the input source with the rotary switch and set the music level using the rotary control. Adjust the microphone mix with the separate control. If you want to use the paging function, when the microphone signal is strong enough, the music will automatically lower in volume. You can adjust the attenuation level on the rear panel. For fire safety, connect the appropriate input to the fire control system. You can choose between isolated contacts or a voltage input. If needed, reverse the input polarity using the internal jumper. When it comes to remote control, you can use the wired control panels or the RS232 interface. If you have multiple units, daisy - chain them together and set different addresses on the rear panel. Some things to note: Make sure to match the source levels using the input gain controls to avoid sudden level changes. When setting the microphone gain, use the MIC LED on the rear panel as a guide. For maintenance, keep the unit in a dry and clean environment. Check the connections regularly to ensure they are secure. If there are any issues with the unit, consult the technical support.
