FA125.2 2-Channel Power Amplifier

The Ashly FA125.2 is a compact, two-channel Class D power amplifier designed for professional audio installations where space, efficiency, and flexible output configuration are important. It delivers 125 watts per channel and features dynamic power sharing, allowing available power to be distributed between the two channels when different loads require different amounts of power. Supporting low-impedance loudspeakers and 70V/100V distributed audio systems, the FA125.2 is suitable for conference rooms, retail spaces, hospitality venues, houses of worship, and other commercial installations.

From The Manufacturer:

Ashly's FA Series combines high-density Class D amplification with a compact half-rack-width chassis. The series is designed to provide reliable amplifier performance in installations where traditional rackmount amplifiers may be too large.

The FA125.2 incorporates power-sharing technology that allows up to 250 watts to be allocated across its two output channels, subject to the manufacturer's operating conditions. It also features quiet active cooling, automatic DSP protection functions, remote control connections, and energy-saving standby operation. Its selectable low-impedance and high-impedance modes support a variety of loudspeaker installations.
