The DX2040 True Diversity Receiver

The DX2040 has 32 pre-programmed frequencies and incorporates enhanced multi-channel operation with a switching bandwidth of up to 24MHz (equivalent to 4 US TV channels).

Powered by 2xAA batteries, the receiver can run up to 5 hours on standard batteries or 10 hours with lithium batteries. Or using cables available from MacArthur Group, it can be powered with a 6-18v external DC power source.

Audio Ltd.s unique infrared interface allows the user to set all parameters via the SwitchiR, a keyfob-sized remote control unit.

Scanning with signal strength on location is possible using AudiR for Palm (available free). This feature is normally only found on mains powered studio based rack systems.

The DX2040 can be plugged directly into the RK3 portable rack system to allow 3 to 6 receivers to be fed from one set of antennae.

If you are upgrading from an earlier Audio Ltd. system, the DX2040 is fully backwards compatible using cables with a standard six pin Lemo connector interface.

Our technical department is available to answer any questions. (Email us at: evan@macarthurgroup.com)
