Class-D power amplifier 2x130W RMS 1U rack - JB SYSTEMS BEG-B08127

The JB Systems AMP 100.2 Mk2 is the Mark II revision of the AMP 100.2 professional power amplifier: a 2-channel Class-D unit rated at 2 x 70 WRMS at 8 ohms and 2 x 130 WRMS at 4 ohms.

Outside, it keeps the previous model’s compact footprint—standard 19" rack width and 1 U height (44 mm). Inside, the layout is fully reworked for reliability and heat dissipation, with three fans holding temperature in check. An extremely efficient soft-start switching supply powers the design.

Three operating modes: conventional stereo with independent channels; mono with linked inputs and mono output (only the LEFT input drives both outputs); bridge mode tying the output stages for 260 W at 8 ohms.

A peak limiter guards against distortion; a low-cut filter rolls off lows at 75 Hz with a 24 dB/oct slope. Selectable input sensitivity: 0.775 V / 1.0 V / 1.44 V. Rear switch for floating ground. Included plastic cover, secured with four screws over the front panel controls, blocks unauthorized input-level changes.

Balanced XLR inputs, link output to daisy-chain another amplifier, speakON speaker outputs. Protection against short circuits, high temperature, and overload.
