The MA60T 2 U Rackmountable Single-Zone Mixer Amplifier from Cloud USA is a reliable, compact, and self-contained source of background music, ideally suitable for installation in retail premises, bars, hotels, restaurants, licensed premises, and many other entertainment locations. It features four stereo line inputs for music sources on phono (RCA) sockets and a balanced microphone input. Any one of the music sources may be user-selected, and mixed with the microphone input to provide paging. Line 2 input is duplicated on a 3.5mm stereo jack socket to permit simple connection of a laptop, portable MP3 player, or similar. An isolating transformer is fitted (selected by internal jumpers) to reconfigure the mic input for use with an analog telephone system, permitting paging announcements to be made from any phone extension.
The MA60T has a 60W power amplifier, which is suitable for low-impedance loads; a transformer (Model CXL-50T) is pre-fitted, and configured for 70V-line operation. A balanced pre-amp output is fitted, the signal being taken from post the level control; this may be used to feed additional power amplifiers. A transformer-isolated auxiliary output is also provided which may be used as an interface for 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 the main output, or be permanently fed with any one of the music sources.
The front panel controls are provided for music source selection, and music and microphone levels. Rear panel controls include gain adjustment for each music source and the microphone input, output HF/LF EQ adjustment, and independent music and mic level controls for the MOH/Utility output.
The MA60T is compatible with Cloud PM Series paging microphones. Alternatively, the Mic input may be configured to suit most short-to-ground OEM paging systems with VOX or access-triggered mic-over-music priority. One line input may be set to have priority over any other selected to facilitate connection of a digital sound storage or similar device. Furthermore, the mixer amplifier features an external Music Mute control input (selectable N/C or N/O) to allow the unit to be interfaced to an external emergency system.
