Symetrix 450 Dual Zone Priority Mixer #2489 - USED

The 450 Dual Zone Priority Mixer is designed for paging and music sound systems in clubs, restaurants, hotels, conference facilities, houses of worship or anywhere multiple audio inputs must be combined and distributed. There are two mono mic/line inputs (with phantom power and low frequency filters) and four stereo line inputs. Each input may be assigned to a stereo output zone, a mono output zone or both.

Unique hierarchical Priority Override structure permits the two mic/line inputs and the first stereo line input to mute the other (lower priority) inputs assigned to the same zone. For example, in a typical configuration, a paging microphone assigned to the stereo zone will have priority over a background music source (connected to line input 5-6) in that zone. A jukebox (connected to line input 3-4) in the same zone will have priority over the background music, but the paging signal will retain ultimate priority and force muting of both the jukebox and the background music whenever the page mic is used.

The 450'sflexibility and simplicity make it the perfect choice for a wide variety ofsystems. By accepting audio inputs from virtually any type of audio source and selectively routing to either the mono or stereo output zone the 450 can save you time and money in the design and installation of your next project
