Microphone Mix DM-20
Built-in receiver
NB! The receiver on the Microphone Mix DM-20 is switched off on de-
livery. Receiver ON under Communication on the menu is not selected.
This function must be activated in order to hear what is being said.
The Microphone Mix DM-20 transmitter also contains a
receiver which enables you to transfer the sound regis-
tered on another Digisystem microphone. For this to be
possible, the radio frequencies of the received and trans-
mitted signals must not be too close to each other.
It is possible to select to transmit at a higher frequency
and receive at a lower one, or vice versa.
The groupings are as follows:
High frequencies (852 - 872 MHz)
¤ Channel 1 - 3
¤ Channel E1 - E5
¤ Channel B1 - B23
¤ Channel F1 - F15
Low frequencies (768 - 785 MHz)
¤ A13 - A55
The transmitter takes priority, and if no suitable frequen-
cy is set for the receiver the receiver will be deactivated.
The Receiver ON option under Communication on the
unit’s menu is deselected.
The frequencies (channels) which cannot be selected for
the transmitter in combination with the built-in receiver
are marked in orange. The receiver will be deactivated if
an orange-marked frequency is selected.
The frequencies (channels) which cannot be selected for
the built-in receiver are marked in red. It is not possible
to select these frequencies.
The simplest way of setting the DM-20 is therefore to
select the transmitted frequency (channel) first.
