When in the level/balance mode and the
minimum output level is set to –40 dB,
turning the level control to its fully coun-
terclockwise position will place both head-
phone output channels to 40 dB below
maximum. This ensures that talent will
never be fully “isolated” from potentially
important cue signals. In addition, rotat-
ing the balance control to either its fully
clockwise or fully counterclockwise posi-
tion will cause the applicable channel to
be 40 dB below its maximum. If set to the
full mute mode, turning the level control
to its fully counterclockwise position will
cause both the left and right channels to
fully mute. In addition, rotating the balance
control to either its fully clockwise or fully
counterclockwise position will cause the
applicable channel to fully mute.
Each control has a mechanical step (de-
tent) that is located at the halfway (50%)
position of its rotation range. The balance
control will typically be set to its center,
detent position, making the level of the left
and right channels equal. In an ideal in-
stallation, the level control can also be set
to its detent position and provide a com-
fortable headphone output level. This will
allow the user, in response to their prefer-
ence or a changing environment, to adjust
the level and balance controls as desired.
The detent positions will always remain as
a useful reference point. To achieve this
condition the audio level on the connected
IFB circuit, or line inputs, must be ad-
justed as required. Spending a few extra
minutes “trimming” the connected audio
levels, rather than just providing what-
ever happens to come up, should prove
worthwhile. The result will be talent that is
more relaxed, and an overall production
that works more smoothly. As previously
mentioned, a level trim potentiometer is
associated with each line input. If the line
inputs are utilized as cue sources, adjust-
ing the trim pots may be helpful in achiev-
ing the desired adjustment range of the
level controls. Refer to the Technical Notes
section of this user guide for details.
Monaural Headphone Output Level
Control Operation
As previously discussed, the headphone
output can be set for monaural operation.
This option is specifically provided so that
a “2-channel headphone mix” mode can
be created. If this has been enabled, the
two front-panel level controls are used
as a cue source mixer. Independent cue
inputs will be assigned to each chan-
nel, serving as the mix sources. How the
controls respond when placed in their fully
counterclockwise position will depend on
the configuration. By default the output
level will be 40 dB below its maximum
level. An alternate configuration will make
the outputs mute.
Sidetone Mode
Whenever the sidetone mode is enabled,
the functions carried out by the rotary
controls are quite unique. The left control
adjusts the level of the “sidetone” confi-
dence audio signal that is sent to the left
and right channels of the headphone out-
put. This audio signal is post-compressor,
and is active whenever the main output,
talkback 1, or talkback 2 functions are
active. The right control adjusts the level
of the cue signals being routed to the left
and right channels of the headphone out-
put. Using the two controls, the operator
can easily create the desired mix of them-
selves (“sidetone”) and the “mix minus”
cue signal(s).
To get maximum performance from the
sidetone mode, one simple calibration
process may need to be performed. If one
