Minimum Level Mode
Switch SW4-3 is used to conﬁgure the

headphone output’s minimum level. In the

–40 dB mode the minimum headphone

output level is 40 dB below maximum. The

headphone output channels will never fully

mute. This ensures that any audio signal

present on the selected Model 230 inputs

will always be present on the headphone

output. In most on-air broadcast applica-

tions this is the appropriate setting.
When the full mute mode is selected and

the level/level mode is also selected, mov-

ing either control to its fully counterclock-

wise position will cause its associated

channel to fully mute.
When the full mute mode is selected and

the level/balance mode is also selected,

turning the level control to its fully coun-

terclockwise position will cause both

headphone channels to mute. Turning the

balance control to either its fully clock-

wise or fully counterclockwise position will

cause the appropriate channel to mute.
Selecting the full mute mode may be

appropriate for applications where mini-

mizing the chance of audio “leakage”

is important. This could occur when the

connected headset or headphones are

at times placed on a desk or tabletop.

Main Button Mode
Switch SW4-4 is used to conﬁgure how

the main button responds to talkback ac-

tivity. Speciﬁcally it applies only when the

system is selected for the on-air mode and

the main output button mode has been

conﬁgured for alternate action or hybrid.

When the main button mode is set to nor-

mal and a talkback function is active, the

main output will, if “latched” on, be tempo-

rarily placed in its off (muted) state. When

the talkback function is no longer active

the main output will return to its previous

latched on state.
When the talkback forces main button

to latch off mode is selected, and a talk-

back function becomes active, the main

output will, if latched on, be placed in its

off (muted) state and the latch condition

forced off. When the talkback function

is no longer active the main output will

remain in the latched off state.
The differences in how the main button

modes impact operation and user comfort

are relatively subtle. The nuances of both

modes should be considered before a

ﬁnal selection is made. If possible, experi-

menting with both modes in a test environ-

ment might prove to be very helpful.
