As the original System 1000 module, the DA-101 remains one of the most versatile amplifiers available to the audio professional. Although the DA-101 is a mono DA, it has two inputs and a signal routing switch, allowing selection of either input 1 or 2, or a mix of both. The DA-101 delivers an incredibly low (0.00044%) THD at 2 kHz. It features 15-turn gain pots, front panel test points, and 13 segment LED meters plus LEDs for power indication. Use it as a 10 output mono DA (up to 100 outputs with build out panel), as a 40 watt mono monitor amplifier, or as a time code DA without crosstalk to other modules. Plug on accessory daughterboards, such as the RGC-06 remote gain control, add significant versatility to the DA.

The DA-101 is a System 1000 card and requires a System 1000 cardframe (MF-302).
