Compact 2-Channel Amplifier

The BZBGEAR BG-AMP2X20 is a bridgeable Class-D stereo amplifier built for installations where a full-sized unit will not fit. It delivers 2 x 20 watts into 4 ohms in stereo mode or 40 watts into 8 ohms when bridged to mono. A 3-level microphone input with mixer function and switchable 48v phantom power supports paging or live vocal use.

Interface Limits

The amplifier accepts three source types: stereo RCA, a 3.5mm jack and a 3.81mm 3-pin pluggable terminal block. Outputs are provided on a 3.5mm jack and a 5.08mm 4-pin pluggable terminal block for speaker wiring. Frequency response spans 20Hz to 25KHz, and control is available via front push buttons, IR remote or RS-232.

Build and Daily Use

A metal enclosure measuring 10 x 8 x 3 inches and weighing 2 lbs is designed to last for years in fixed installations. The compact footprint allows mounting behind displays, in lecterns or inside equipment racks where space is tight. Pluggable terminal blocks make speaker and microphone connections secure and serviceable without soldering.

Questions about this item

Should I run the BG-AMP2X20 in stereo or bridge-mono for my speakers?

Choose stereo for two 4-ohm speakers at 20 watts each, or bridge-mono for one 8-ohm load at 40 watts.

What does 20 watts at 4 ohms deliver in a typical install?

It drives a pair of 4-ohm bookshelf or ceiling speakers to comfortable listening levels in small to medium rooms.

Which control method — RS-232, IR or front buttons — is best for a fixed rack?

RS-232 integrates with control systems for automated power, volume and input switching; IR and buttons remain available for local adjustments.
