When the rotary level control on the right
side of the front panel has been assigned
to control the sidetone level the setting of
the headphone minimum level mode will
not impact it. In this case when the control
is in its fully counterclockwise position it
will always cause the sidetone level to be
fully muted.
Tally Tone/Hot Mic Out
Switch SW1-10 selects whether the tally
tone or the hot mic function will be enabled.
System Mode
Switches SW1-11 and SW1-12 are used
to configure the overall operating mode
of the Model 215. Specifically, they deter-
mine how the main output channel oper-
ates vis-à-vis the talkback output channels
as well as one facet of the headphone
output’s function.

When in its Off (down) position the tally
tone function will be enabled. The tally
tone function will cause a 20 kHz sine
wave to be present on the designated
Dante transmitter (output) channel when-

plifier is being routed to the main Dante
transmitter channel. When Switch SW1-10
is in its On (up) position the hot mic func-

from the output of the microphone pream-
plifier to be always present on the Dante
output channel.
Note that the name of the Dante transmit-
ter channel used by both the tally tone
and hot mic functions has a default name
of Tally Tone/Hot Mic. This can be revised
as required using the Dante Controller
application.

that correct operation and maximum us-
ability will occur.
• When selected to the on-air mode, the
audio signal on the main output chan-
nel will mute whenever the audio signal
on either or both of the talkback output
channels is active. The on-air mode
should be selected for all on-air broad-
cast applications when it’s imperative
that the audio signal on the main output
channel be muted whenever on-air talent
uses a talkback output channel to com-
municate with production personnel.
• When the system mode is set for produc-
tion with dim, the audio signal on the
main output channel is never muted in
response to the audio signal on either
or both of the talkback output channels
being active. In addition, the level of
the headphone output is dimmed (re-
