Recommended receive audio input level:
The DRA-36M accepts the widest range of audio compared to any other similar radio adapter. The input signal is attenuated by a potentiometer, giving the broadest range of acceptable levels. As little as 20 mV P-P, and as much as 20 volts P-P. If your receive audio level is adjustable or programmable we recommend around 2.0 volts P-P. This allows very good signal-to-noise ratio and low cabling cross talk. This level results in a 50% rotational setting of the potentiometer.

All DRA-36M's are supplied with a Genuine C-Media CM119A, but the DRA-36M board was designed to be versatile. It will accept a CM119 (without the A) and even the CM108. There are slight differences between these components, and the board can be 'programmed' to accept any of the three.

Secure PayPal ordering is available from the DRA-36M main page.

DRAC-12 - 6-foot Mini-DIN-6 Radio Cable  can be added optionally to connect several data capble radios to the DRA-36M.
