The 46-120 4-Zone 2U Rack-Mountable Mixer Amplifier from Cloud USA combines simple control of background music, microphone paging, and power amplification for up to four zones in a single unit. It is suitable for use in many types of premises, such as pubs, bars, clubs, leisure, and fitness centers, shops, offices, hotels, and more. It has six stereo line inputs and two microphone inputs; one mic input can be configured for paging purposes. Each line and mic input has its own preset sensitivity control on the rear panel, and each mic input additionally has HF/LF EQ adjustment to optimize the inputs for better clarity.
The 46-120 has four mono zone outputs, each being driven by a 120W power amplifier stage. Pre-power stage outputs (0 dBu, unbalanced) are also provided for Zones 1 and 2. Line 6 input may be set to have priority over any other selected music source in Zone 1, to facilitate connection of a jukebox, digital sound store, or similar device. The priority feature has selectable release times, to allow a smooth return to the original music source.
A transformer-isolated auxiliary output is also available which may be used as an interface to telephone MOH systems, or as a utility output to drive a local rack monitor or an induction loop amplifier. This output may be selected by internal jumper to either follow Zone 1's selected music source summed with Mic 1, be permanently fed with any one of the music sources. Separate rear panel preset controls are provided to set the music and Mic 1 levels at this output.
The mixer amplifier is compatible with all Cloud PM Series paging microphones. The paging mic input can be configured to suit most OEM paging systems. Zone selection for paging is via short-to-ground access connections, and the unit may be configured by internal jumper for automatic music ducking (mic-over-music priority), triggered by VOX control. Furthermore, this mixer amplifier features a Facility Port that allows remote input plates of various types (sold separately) to be connected so that mic and/or line sources such as radio mics, DJ mixers, iPods, laptops, or other audio sources can be connected in the zone itself. A remote Music Mute facility is provided, which can be used to satisfy the requirements of the Local Fire Officer.
