MPA 5240
unit offers balanced line input and output via XLR‑F and XLR‑M sockets with adjustable sensitivity, alongside an unbalanced line input via double RCA connectors. It also provides a dedicated RJ45 socket for connection of a MBT 1101‑series microphone station, and a telephone/emergency audio input with adjustable threshold and sensitivity for priority calls. On the front panel, there is a master volume control along with bass and treble tone controls, while a rear‑panel selector switch enables or disables the front panel’s tone and volume controls. The loudspeaker line output supports constant‑voltage operation (50 V / 70 V / 100 V) or 8 Ω impedance connection. An LED‑type VU‑meter on the front gives immediate visual feedback of output power. Also included are contact inputs for activating input precedence (override) and a built‑in alerting chime with level control. The unit supports selectable power supply modes at 230 V AC / 115 V AC and 24 V DC mains.
