BOSCH LBD1930/00 Plena Booster Amplifier 120 W

Description

Bosch LBD1930/00 Plena Booster Amplifier 120 W – Wide range of power amplifier from 120W,240W and 480W – Multiple outputs – 70 V / 100 V and 8/4 ohm – Temperature controlled forced front to back ventilation, directly stackable – Mains, battery back-up, and pilot tone supervision – Dual inputs with priority switching (LBD1938) – Warranty one year as per manufacturer.

Bosch LBD1930/00-120w Plena Booster Amplifier 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.

Bosch LBD1930/00-120w Plena Booster Amplifier 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

The 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, if the internal temperature reaches a critical limit due to poor ventilation or overload.

The 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 100V line input is provided to connect the amplifier to a 100V 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.
