About Plena Booster Amplifier 120 W LBD1930/00

The LBD1930/00 amplifier is a powerful power amplifier in a 2U high 19"case 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 LBD1930/00 amplifier features a colorful LED bar on the front side to indicate the acoustic level of the signal in dB. The LBD1930/00 amplifier has a 100V input for slave operation of the amplifier, XLR loop in and loop through facility for ease of installation and a 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.

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

Excellent signal to noise ratio (> 80 dB)

High-Quality Sound Performance

Enjoy clear audio with a wide frequency response of 60 Hz to 18 kHz. The amplifier offers tone controls for both bass and treble, and keeps harmonic distortion below 1% at rated output so voice and music remain distinct and polished. Forced air cooling further ensures performance consistency even during extended use.

Flexible Input and Output Options

Supporting 1 line input, 1 mic input, and 1 emergency input, the LBD1930/00 easily adapts to varied setups. Output terminals allow connection to external speakers using 100 V, 70 V, or 8 Ohm configurations, suitable for both distributed and point-source sound reinforcement.

Reliable Installation and Operation

The amplifier is rack-mountable in standard 19-inch racks, featuring a rugged metal chassis finished in matt black enamel paint. Protection against overload and short-circuit, together with standby power consumption below 5 W, ensures long-term reliability and efficiency for public address systems.
