The 46-50T 4-Zone 2 U Rackmountable 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 46-50T has four mono zone outputs, each being driven by a 50W (nominal rating) 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.
Any or all of the outputs may be configured as high impedance, allowing the 46-50T to drive 70V-line loudspeaker systems with the addition of an optional 4-channel, internally-fitting transformer module. Alternatively, single transformers are available as standard accessories for external connection. If less than four separate zones are required, the power amplifier stages for Zones 2 and/or 3 may be fed with the program from Zone pre-amp sections 1 and/or 4 respectively, doubling the amplifier power available. The front panel provides separate user controls for adjusting the level of each mic input, music source selection, and music level, for each zone. Preset controls for HF and LF EQ adjustment of each zone output are also fitted.
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.
