  • 1Description

The DA-550F-HL from TOA Electronics is a high-quality, rack mountable four-channel digital amplifier. Designed for highly efficient operation, the DA-550F-HL is capable of outputting 550W per channel at eight Ohms. Each channel has an individual level control knob, and all input connections are via 3-pin removable terminal block. Output connections are made on a standard screw terminal strip.

The DA-550F-HL has an internally settable high-pass filter, as well as built-in protection circuitry to protect against damage from overheating and overloads. Four front-panel air vents each offer removable dust filters for easy maintenance to ensure your amplifier keeps running smoothly. Bridged operation is available via simple push-button operation if desired.
