Product Details

The Plena system pre-amplifier is a versatile, highperformance unit with call and mono BGM (background music). It fulfills a wide variety of public address requirements at a surprisingly low cost. It can provide dual channel operation for simultaneous calls and BGM for up to six different zones, using two Plena amplifiers.

Functions

The call channel provides two inputs for the Plena call stations, LBB 1941/00 (all-call) or LBB 1946/00 (six-zone), with loop-through capability, and universal, balanced input. One is a 3-pin connector for microphone or line level (selectable), and the other is a 5-pin DIN-connector with all‑call priority contact, which may also be used to start one of the available chime attention signals.
The microphone input has a selectable speech filter for improved intelligibility, a volume control, and bass and
treble tone controls with shelving characteristics optimized for speech. The call channel is available on the balanced master output.

»	Six-zone system pre-amplifier, with single or dual channel operation
»	Two input channels for call stations
»	Universal input for microphone/line, with speech optimized tone control
»	Three inputs for BGM selection and music optimized tone control
»	Front panel zone selection for BGM and call station zone selection for calls
»	PC and trigger inputs for automated calls, alarm tones and chimes to selected zones

The BGM channel provides three inputs on stereo cinchconnectors, converted to mono, with front panel selection, volume control and bass and treble tone controls with shelving characteristics optimized for music. The BGM channel has a direct output on balanced for dual channel operation. It can also feed the master output, with the lowest priority, for single channel operation. Zone selector switches on the front panel control the BGM routing. An overload protected 24 VDC output provides power for driving external relays, often making an external power supply unnecessary.
An emergency/telephone input with signal level detector (VOX) and volume preset has the highest priority to all
zones. Two trigger inputs (contact closure) activate alarm or time signals to pre-selected zones. Many different chime tones are available. A PC audio input with RS-232 control provides software controlled zone configuration, or automatic messaging in combination with the LBB 1965/00 Plena Message Manager. There are six levels of priority available for BGM, microphone, call stations, trigger inputs and emergency input. A set of relays directs the amplifier output(s) to different loudspeaker groups (zone switching).
