Main Output vis-à-vis Talkback Activity
This short section applies only in the case

where the Model 220’s system mode is

conﬁgured for on-air and the main output

button mode is set to alternate action or

hybrid.
How the main output responds to talk-

back activity depends on the conﬁgu-

ration of the main output mode. In the

normal mode talkback activity will always

cause the main output to be placed in

its off state. If the main output was in the

“latched” on state when talkback began,

once talkback activity ends that state will

resume; the main output will again be in

its on (“latched”) state. If the main output

mode is conﬁgured to force off, talkback

activity will cause the main output to be

placed in its off state. Once talkback activ-

ity ends the main output will remain in its

off (“unlatched”) state. In critical on-air

broadcast applications it’s important that

a Model 220 user be aware of how the

selected mode impacts operation.
Talkback 1 Button and LED Indicator
The button in the center, factory labeled

TALKBACK 1, controls talkback output 1.

The manner in which the button functions

depends on the way it was conﬁgured. An

LED indicator, green in color, is located

directly above the button. It lights when-

ever the talkback output 1 is active. If the

Model 220 is selected to the on-air mode,

whenever the talkback output 1 function is

active the main output will be placed in the

muted state. If the Model 220 is selected

to the production mode, the status of

talkback output 1 will not impact the main

output.

Talkback 1 Button Modes
• Push to talk: If this mode is selected

talkback output 1 is normally muted.

The output will become active whenever

the button is pressed and held.

• Hybrid: This mode is a combination of

push to talk and alternate action. If the

button is pressed and held, talkback

output 1 will become active until the but-

ton is released. If the button is momen-

tarily “tapped” the output will change

state. Upon Model 220 power up talk-

back output 1 will be in its muted state.

Talkback 2 Button and LED Indicator
The button on the right, factory labeled

TALKBACK 2, controls the function as-

sociated with the talkback 2 button. The

manner in which the button functions de-

pends on how it was conﬁgured. An LED

indicator, green in color, is located directly

above the button. If the talkback 2 function

mode has been conﬁgured for enabled, it

lights whenever talkback 2 is active. If the

talkback output 2 function mode has been

conﬁgured for disabled, it will light only if

the auxiliary relay has been assigned to

follow the talkback 2 button.
If the Model 220 is selected to the on-air

system mode, whenever talkback 2 is ac-

tive the main output will be placed in the

muted state. If the Model 220 is set to the

production system mode the status of talk-

back 2 will not impact the main output.
Talkback 2 Button Modes
• Push to talk: If this mode is selected the

function associated with talkback 2 is

normally off. The function will become

active whenever the button is pressed

and held.
