Description
The AMP-D225H is a two-channel class D amplifier delivering 25 watts per channel in a sleek, compact design. Because there is no need for internal cooling fans, the AMP-D225H can be placed in a conference room with virtually no audible noise. The ability to bridge channels gives even more power and flexibility to the AMP-D225H. The AMP-D225H is also equipped with four stereo inputs, four GPIO, and two RS-232 interfaces. It integrates easily with a variety of control systems and the USB input enables direct audio connection and volume control from a computer. It’s audio performance, ease-of-use, and versatile feature set makes the AMP-D225H ideal for a variety of professional audio applications.
Features:
- Two channels; 25W per channel
