The DD Audio ATC-400 is a terminal amplifier designed to replace the terminal of DD Audio LE pre-fabricated enclosures, turning them into active versions.

Easy to install: Remove the terminal of the LE pre-fabricated enclosure and cut or disconnect the cable from the original terminal. Then connect the cables inside the enclosure to the ATC-400 speaker cables (we recommend tinning the cables together and using heat shrink tubing to protect them), after which you can screw the amplifier into the terminal opening of the enclosure.

The DD Audio ATC-400 amplifier has two crossover selections: SUB (SUBWOOFER) and FR (FULL RANGE). When the SUB selection is used, the frequencies in use are 30-80 Hz, and when the FR selection is used, the frequencies are 80 Hz - 25 KHz.

The amplifier has a separate turn-on switch: The REM selection uses a traditional remote turn-on wire, the RCA selection turns on the device when a signal is present in the RCA connectors, and the DC selection turns on the device when a speaker-level signal is fed to the RCA connectors (adapter to be purchased separately).

A wired bass level control is included in the package.

(The amplifier can also be used in enclosures other than LE enclosures).
