both the left and right channels. The bal-
ance control, located on the right, adjusts
the relative left/right level balance. In this
mode the controls operate in a manner
reminiscent of a consumer audio ampli-
fier or receiver. If set to the normal mode,
rotating the balance control in the coun-
terclockwise direction reduces the level of
the right channel providing the user with
more perceived level in the left channel.
If set to the reverse mode, rotating the
balance control in the counterclockwise
direction reduces the level of the left chan-
nel providing the user with more perceived
level in the right channel.
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
(detent) 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 installation, the level control can also
be set to its detent position and provide a
comfortable headphone output level. This
will allow the user, in response to their
preference 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 adjusted as required. Spend-
ing a few extra minutes “trimming” the
connected audio levels, rather than just
providing whatever 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 potenti-
ometer is associated with each line input.
If the line inputs are utilized as cue sourc-
es, adjusting the trim pots may be helpful
in achieving 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.
