The Cloud MA60media is a rack-mounting (2U, half-width), singlezone mixer-amplifier combined with an integral digital media player. It 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. The MA60 has all of the features and facilities of the MA60media, but without the internal digital media player. It is ideal for any application where a well-featured and cost-effective mixer-amplifier is required. Both models have 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. Phantom power is available at the mic input. Line 2 input is duplicated on a 3.5 mm 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 analogue telephone system, permitting paging announcements to be made from any phone extension. On the MA60media, the internal media player may be selected as the Line 1 source. It can play MP3 and WMA files directly from a USB device or SD memory card. All standard data rates and sampling frequencies are supported. Both models have a 60 W power amplifier, which is suitable for lowimpedance loads; a transformer (Model CXL-50T) may be readily retrofitted internally to allow 100/70/50 V-line systems to be driven. [Note: for the North American market only, alternative models MA60T and MA60Tmedia are available; these have the CXL-50T transformer pre-fitted, and configured for 70 V-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 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 the main output, or be permanently fed with any one of the music sources. Front panel controls are provided for music source selection, and music and microphone levels. The front panel of the MA60media also has a socket for a standard SD memory card, and a USB port for connection of USB memory sticks. A conventional set of “transport” buttons allows Start and Stop, Next and Previous Track/File, and selection of Random and Repeat modes. 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 MA60media and MA60 are directly 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 store or similar device. Music level only, or music level and source selection may be controlled remotely if wished, using a Cloud RL-1 or RSL-4 remote control plate (respectively). In common with most Cloud audio products, EQ cards to match various popular ranges of installed-sound loudspeakers may be fitted to the amplifier stage. An external Music Mute control input is provided (selectable N/C or N/O) to allow the unit to be interfaced to an external emergency system.
