Mixed Digital/Analog Systems
When digital wireless and analog wireless systems are used together, take the following points into
consideration.
Channel plan limitations
In a mixed digital/analog wireless system, channel plans designed for analog systems must be used.
Equal channel spacing applies only to fully digital wireless systems. Equal channel spacing is not available
for analog wireless systems.
Notes
Common frequency interference precaution
When operating adjacent to an analog wireless system, the minimum distance for analog wireless systems
must be observed.

Refer to Sony digital wireless system frequency lists for further details on pre-programmed groups of
frequencies built into every DWX transmitter and receiver.
Sony's built-in pre-programmed frequency groups provide 500 kHz channel spacing for digital channel
plans D1-D9 along with analog channel plans 01-09 (containing irregular channel spacing) to ensure
compatibility with Sony analog wireless system channel plans.
