BOSCH LBD1935/00, 240W, Plena Booster Amplifier

Description

The LBD 193x amplifiers are powerful power amplifier in a 2U high 19”case (3U housing for LBD 1938) for rack mounting or tabletop use. The Bosch Plena power amplifier series with its varied amplification range fulfills a wide variety of public address requirements at a surprisingly low cost. The LBD193x amplifiers feature colorful LED bar on the front side to indicate the acoustic level of the signal in dB

LBD193x amplifiers have 100V input for slave operation of the amplifier, XLR loop in and loop through facility for ease of installation and 100V output as well as 70V output for connecting to the loudspeakers with line matching transformers,8ohm and 4ohm outputs for connecting to the Low impedance speakers.

The output voltage can be selected between 100V and 70V internally. Additionally LBD1938/00 amplifier features a dual XLR inputs with priority switching Gain or level control is located on the rear of the unit to avoid accidental setting change.

The amplifier works on 24VDC power supply during emergency situations. A temperature-controlled fan ensures high reliability at high output levels and low acoustic noise at lower output level.An overheat protection circuit switches off the power stage,if the internal temperature reaches a critical limit due to poor ventilation or overload.

An additional 100V line input is provided to connect the amplifier to a 100V loudspeaker line to provide more power to remote locations LBD1938 amplifier also has priority controlled 100V outputs which can be used to route audio coming into priority and program inputs to the loudspeaker.

The LBD1938/00 amplifier has priority input and program input on the rear which can be used for routing important or emergency announcements when the amplifier is being used as a independent amplifier(ex: with local music source connected to program input)
