Reverse Left/Right Mode
Switch SW4-2 is used to select whether
the rotary controls are in the normal or
reverse left/right mode of operation. When
selected to the normal mode, and level/
level mode is also selected, the left control
adjusts the level of headphone output’s
left channel. (This is the signal that
appears on the tip lead of the ¼-inch
3-conductor jack.) The right control ad-
justs the level of the right channel. When
selected to the normal mode, and the lev-
el/balance mode is also selected, turning
the balance control in the counterclock-
wise direction increases the perceived
level of the left channel, and vice versa. the user is provided with a consistent
and easy-to-use set of headphone level
controls.
Minimum Level Mode
Switch SW4-3 is used to configure the
headphone output’s minimum level. In
the –40 dB mode the minimum head-
phone output level is 40 dB below maxi-
mum. The headphone output channels
will never fully mute. This ensures that
any audio signal present on the selected
Model 220 inputs will always be present
on the headphone output. In most on-air
broadcast applications this is the appropri-
ate setting.

When the full mute mode is selected
and the level/level mode is also selected,
moving either control to its fully counter-
clockwise position will cause its associ-
ated 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 clockwise
or fully counterclockwise position will
cause the appropriate channel to mute.
Selecting the full mute mode may be
appropriate for applications where mini-

As you may have already guessed, when
selecting the reverse left/right mode of op-
eration everything is reversed! To be more
specific, when selected for reverse mode,
and the level/level mode is also selected,
the left control adjusts the headphone
output’s right channel (output jack’s ring
lead) while the right control adjusts the
left channel. When selected to the reverse
mode, and the level/balance is also se-
lected, turning the balance control in the
counterclockwise direction increases the
perceived level of the right channel, and
vice versa.
The reverse mode is provided specifically
for cases where a headset’s left and right
ear pieces are placed on a user’s head
in a reverse orientation. This ensures that
