Selecting Audio Polarity
Audio polarity can be inverted at the transmitter so the
audio can be mixed with other microphones without
comb filtering. The polarity can also be inverted at the
receiver outputs.

Compatibility modes are as follows:
DBSM/DBSMD:
• Standard Mono Digital

• High Density Mode

HDM Mode (High Density Transmission)
This special transmitting mode and associated low RF
power of 2mW allows the user to "stack" many units into
a very small area of the spectrum. Standard, ETSI-com-
pliant RF carriers take up about 200 kHz of occupied
bandwidth, while HDM takes up about half of that, or
100 kHz, and allows for much tighter channel spacing.
