The BXX1200.1D is a 1200 watt mono amplifier featuring Super Class D technology with an NGSD digital chip to provide you with an extremely efficient, low temperature, high amplification system that others only dream about.

The rock solid Ultra-Fi MOSFET outputs are selected for both balance and output power. This keeps power smooth even during demanding peak in the music.

The amplifiers protection condition is also shown by blue illumination for normal operation and red for a short being present and requires the attention of an installer.
