The DD Audio ATC-250 is a terminal amplifier designed to replace the original terminal on the DD Audio LE series enclosures.

The installation is very easy: remove the original terminal and cut or detach the cable from it. After this, connect the enclosures cables to the ATC-250′s speaker cables (we recommend tinning the cables together and using heat shrink tubing to protect the cables), after this you can screw the amplifier to the enclosure.

The DD Audio ATC-250 amplifier has two crossover filter selections: SUB (SUBWOOFER) and FR. ( FULL RANGE ). When using the SUB selection, the available frequencies are 30-80 Hz, and when using the FR selection, available frequencies are 80 Hz – 25 KHz.

The ATC-250 has a remote switch: with the REM setting, it uses a traditional trigger cable, with the RCA setting, the device wakes up when a signal is received to the RCA connectors

The package includes a wired bass level controller.

(Note! The amplifier is also perfectly suitable for playing subwoofers other than LE enclosures )
