range has been acquired, select the

desired active sidetone level.
To exit the sidetone level conﬁguration

mode and store the selected sidetone level

press the main output button once. The

selected sidetone level value is stored in

“ﬂash” (protected) memory and normal

Model 230 operation resumes.
From now on, as long as the Model 230

remains in the production mode, sidetone

audio at the conﬁgured level will be provid-

ed to the headphone output whenever the

main output is active. It will also be active

whenever the talkback functions assigned

to the two talkback buttons are active.
To get maximum performance from the

active sidetone feature, one simple calibra-

tion process may need to be performed.

If one or both of the talkback-to-intercom

functions are conﬁgured for use the

“passive” sidetone trim pots associated

with them should be set for minimum

sidetone level. This is accomplished by

adjusting the trim pots to their fully counter-

clockwise positions. This will minimize the

level “build up” that would occur when

both the active and the passive sidetone

audio is being sent to the headphone

output. The goal is for the sidetone level to

remain as constant as possible, no matter

what function (main output, talkback-to-

line-level-output, or talkback-to-intercom)

is active.
On-air with Special Sidetone Mode
When the system mode is set to on-air with

special sidetone, the functions carried out

by the rotary controls are quite unique.

The left control adjusts the level of the

“sidetone” conﬁdence audio signal that

is sent to the left and right channels of

the headphone output. This audio signal

is post-compressor, and is active whenever

the main output or one of the talkback func-

tions is active. The right control adjusts the

level of the cue signals being routed to the

left and right channels of the headphone

output. Using the two controls, the operator

can easily create the desired mix of them-

selves (“sidetone”) and the “mix minus”

cue signal(s).
When the Model 230 is in the on-air with

special sidetone system mode, the reverse

left/right and minimum level modes are still

recognized. However, the conﬁguration that

selects the dual channel (“level/level”) or

stereo (“level/balance”) mode is not recog-

nized. The active sidetone function is also

not available when the Model 230 is in the

on-air with special sidetone system mode.
To get maximum performance from the

on-air with special sidetone mode, one

simple calibration process may need to be

performed. If one or both of the talkback-to-

intercom functions are conﬁgured for use

the null/sidetone trim pots associated with

them should be set for minimum sidetone

level. This is accomplished by adjusting

the trim pots to their fully counterclockwise

positions. This will minimize the level “build

up” that would occur when both the active

and the passive sidetone audio is being

sent to the headphone output. The goal is

for the sidetone level to remain as constant

as possible, no matter what function (main

output, talkback-to-line-level-output, or talk-

back-to-intercom) is active.
