TOA Electronics designed the 4-channel DA-550F to put 550W at 4 ohms into each of its four outputs. These output channels can be independently power-controlled and the power status, protection, and fan operation for each can be monitored. Inputs use an XLR3-31 connector and include removable terminal blocks while the outputs are on M4 screw terminals. An input signal to Channel 1 can be routed to all channels, and the output level adjusted using the input level control for each channel. The rear panel features two RJ45 connectors for remote control and monitoring.
