The front panel has two rotary level controls, for microphone and music inputs. Each has an LED to indicate peak level. A rotary switch selects one of four sources as the music input. A large rocker switch with associated LED indicator turns the power on and off.
The rear panel has a balanced input for a paging microphone using a 3-pole detachable 'Euroblock' or 'Phoenix' style terminal-block connector. A 2-pole version provides the access connection, and gain is set by a screwdriver-operated rotary control. Four pairs of RCA (phono) connectors provide the line inputs; each pair has a screwdriver-operated rotary control to set gain. The second pair of line inputs also has a 3.5mm stereo jack socket as an alternative connection. A 3-pole Euroblock connector provides the input for the optional remote control panels, RL-1 or RSL-4, with a switch to select between local and remote. A 2-pole Euroblock provides the music mute input which may be a normally open or closed contact.
A 4-pole Euroblock provides the connections for the music-on-hold output, which has two adjacent screwdriver-operated rotary controls to set the level of the microphone and music to this mix. A 3-pole Euroblock provides the balanced pre-amp output. Two further screwdriver-operated rotary controls adjust the EQ to the main output. Two 2-pole Euroblocks provide the low impedance loudspeaker output and the external standby connection. A metal cover protects the high-impedance loudspeaker outputs when present. Power is connected to an IEC inlet, with associated fuse.
Included accessories: Manual, AC power cable, mating terminal-block connectors.
Optional accessories: The CXL-60T line transformer may be fitted by the user to give 50V, 70V, 100V line outputs. The PM1 paging microphone is a desk-top gooseneck microphone with a single press-to-talk button. The RL-1 remote control plate fits a standard single-gang UK back-box and gives control of level using screened 2-core cable up to 100 metres long. The RSL-4 provides four-way source selection and level control. RE-L and RE-S mounting kits fit either one or two MA Series mixers in a 19 inch rack.
