counterclockwise direction reduces the
level of the right channel providing the user
with more perceived level in the left chan-
nel. 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, turn-
ing the level control to its fully counterclock-
wise position will place both headphone
output channels to 40 dB below maximum.
This ensures that talent will never be fully
“isolated” from potentially important cue
signals. In addition, rotating the balance
control to either its fully clockwise or fully
counterclockwise position 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 counter-
clockwise 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 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 adjusted
as required. Spending 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 potentiometer is associated with each
line input. If the line inputs are utilized as
cue sources, 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 channel, 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.
Active Sidetone Operation
During normal Model 230 on-air applica-
tions users are typically provided with
sidetone whenever the main output is
active. (Sidetone is defined as the user’s
own voice signal being returned to them as
a headphone cue source.) This helps the
user create a more effective performance
as well as receiving an on-air indication.
But when the Model 230 is configured for
one of the production modes, sidetone
often isn’t available as part of cue sources.
This seems like an unimportant issue, but
