TOA Electronics' DA-250FH is a four-channel digital amplifier that may be rack mounted. The DA-250FH is capable of outputting 250W per channel and is designed for excellent efficiency. All input connections are made via a 3-pin detachable terminal block, and each channel has its own level control knob. A normal screw terminal strip is used to connect the outputs. The DA-250FH contains a high-pass filter that may be set internally, as well as built-in protection circuitry to guard against overheating and overloads. Each of the four front-panel air vents has a replaceable dust filter for easy maintenance, ensuring that your amplifier runs smoothly. If needed, bridged operation is possible with a simple push-button action.
