The ADA-1003 is a dual 1×4/single 1×8 gain controllable analog audio distribution amplifier (DA). It is used in i-MOD platform. The module supports either a dual-channel DA with 4 analog audio outputs for 1 analog audio input on each channel; or single-channel DA with 8 analog audio outputs for 1 analog audio input. Each first output supports power-off protection. Thus signal can be output continuously when module is removed or power is off.

The ADA-1003 can be controlled locally by means of an intuitive card-edge interface or remotely using i-MOD platform control software IM-MASTER.
