CLOUD MPA SERIES MIXING AMPLIFIERS - Single zone
Cloud MPA Series mixing amplifiers are intended for single zone commercial audio installations such as airport lounges, restaurants and retail environments where music, announcement and paging are required. Two versions exist, differing in the rated power of the amplifier stage, along with the physical dimensions of the amplifier.
A 1U, 120W mixer amplifier that offers two balanced microphone inputs and six unbalanced stereo line level inputs, all by way of 3-pin, 3.5mm-pitch screw terminal connectors. 12V phantom power is available for use on either or both microphone input channels. VOX mic over music priority is user selectable on both microphone inputs, whilst an automatic Mic 1 over Mic 2 is default in Page mode. Also user selectable is Line 6 input priority with a selection of release times.
The mono summed 120W output can be combined with 4ohm speakers, or either 70V or 100V line speaker system.
A facility port allows the connection of BT-1 series and LM-2 series remote input modules via Cat5 cable. The facility port is equipped with a noise gate threshold that eliminates background noise in the absence of an input signal. MPA120MK2 is also compatible with other standard Cloud remotes including RL-1 and RSL-6 series.
A 2U, 240W mixer-amplifier offering six line and four microphone inputs which are mixed to a single zone output via configurable 25/70/100V internal transformer. All six line level inputs are via unbalanced stereo RCA (phono) sockets. Gain control of each input is provided in order to balance input levels from different source devices, along with 'Music EQ' LF and HF pre-sets via 'tamper proof' screw terminals.
Selectable priority of line input 6 and release time (3s/6s/12s) can be set via internal jumper. This can be particularly useful and will facilitate system designs which include timed or contact (N/O and N/C) triggering of announcements and chimes from external media players. Four balanced microphone inputs, each with gain control and selectable high pass filter are via Euroblock connector. Each has VOX priority over music signals, providing 30dB of attenuation. Mic 1 has access triggered priority over other mics, with integrated chime. Selectable 15V phantom power is available to all mic inputs.
A 'Music Mute' input is provided via Euroblock connector which may permit compliance with local Fire Authority regulations. Note: microphone inputs remain active when the Music Mute is applied. Selection of the 'Music Source' line input is via front panel rotary knob along with master music level and independent mic level controls.
Optional accessories: A 'Remote Music Control' input makes MPA mixing amplifiers compatible with Cloud RL-1 and RSL-6 wired remote controls. XLR-F1 and XLR-M1 connector plates available, see CLOUD REMOTE CONNECTOR PLATES for further details). The PM-1 paging microphone is a desk-top gooseneck microphone with a single press-to-talk button.
