and easy-to-use set of headphone level controls.

Minimum Level Mode

Switch SW4-3 is used to configure the minimum headphone output level for the controls located on the far left and center. (This setting doesn’t impact operation of the sidetone level control which is located on the far right.) In the –40 dB mode the minimum output level for the control on the far left and the control in the center is 40 dB below maximum; the outputs will never fully mute. This ensures that any cue audio signals present on the selected Model 233 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, mov- ing the control on the far left or the control in the center to their fully counterclockwise positions will cause their associated chan- nel to fully mute. (This is identical to how the sidetone control, located on the far right, always functions.)

When the full mute mode is selected and the level/balance mode is also selected, turning the control configured for level to its fully counterclockwise position will cause both headphone channels to mute.

Turning the control assigned to be the bal- ance 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- 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 to 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 When the talkback function is no longer active the main output will return to its previous latched on state.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 unlatch 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 When the talkback function is no longer active the main output will re- main in the latched off state.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
