480 W power amplifier in a compact housing » 70 V / 100 V and 8 ohm outputs » Dual inputs with priority switching » 100 V input for slave operation on 100 V speaker line » Temperature controlled forced front to back ventilation, directly stackable » Mains, battery back-up, and pilot tone supervision » TÜV certified according to IEC 60849 The LBB 1938/20 is a powerful 480 W power amplifier in a 3U high 19”case for rack mounting or tabletop use. LEDs on the front panel show the status of the amplifier: power, audio output level, and supervised functions. This highperformance unit fulfills a wide range of public address requirements at a surprisingly low cost. Functions DependabilityThe amplifier is protected against overload and short circuits. A temperature-controlled fan ensures high reliability at high output levels and low acoustic noise at lower output levels. An overheat protection circuit switches off the power stage and activates an LED on the front panel, if the internal temperature reaches a critical limit due to poor ventilation or overload.The unit operates both on mains power and on a 24 V battery power supply for emergency back up, with automatic switchover.For emergency and evacuation use, the following functions are monitored: mains presence, battery present, pilot tone presence, amplifier operation. Front panel LEDs indicate the status of supervised functions. The LEDs of pilot tone supervision and battery status can be switched off for general public address use. Failsafe (normally energized) relays are provided for each supervised function. These relays are always active regardless of the switches on the rear panel.InputThe system has two balanced inputs with priority control, each with a loop-through facility. This makes it easy to connect remote systems that require priority control. An additional 100 V line input is provided to connect the amplifier to a 100 V loudspeaker line, to provide more power to remote locations.Gain or level control is located on the rear of the unit to avoid accidental setting change. A meter with LED-bar shows the output level.OutputThe amplifier has 70 V and 100 V outputs for constant voltage loudspeaker systems and a low impedance output for 8 ohm loudspeaker loads.The LBB 1938/20 has two separate priority controlled 100 V outputs for zones that only need announcements made via the priority input, and for zones that will not get any announcements made via the priority input.
