Momentary will take the commentator off air only while the key is pressed. Latching will switch off air
and remain off air until the key is pressed again.
Comm Inputs
Each commentators audio listen inputs designated Talkback, Prog, Aux1 and Aux2 may be individually
selected to be sourced either from the XLR inputs or the first four of the multiway pairs. This enables
each commentator to hear different talkback etc. and so the commentary box may be effectively used
to work with two different trucks or productions. Select which commentator you wish to set and toggle
the inputs between XLR or Multi.
Guest Listen
The guest headphone output hears the same mix as commentator A. Each of comm A feeds may be
switched on or off to the guest. If for example you just wish the guest to hear just programme and the
commentators then just switch these feeds on and the others to off. The first four feeds come up on the
first menu page. Press more for the second four feeds. Overall level adjustment is available on the main
(top) menu.

This selects the next set of menus.
Mix limiter
This is used to set the limiter threshold for the mixed output. This limiter is inserted after the individual
commentator limiters and is available to limit the overall mix. If not required just set the threshold to
+24dB.
S/T Switching
Some commentators prefer to hear their voice at all times, some prefer it to cut when they are off air
and using the lazy talkback. Switch sidetone with lazy (Yes/No).
TX Light Colour
The TX switch lights (Mic Live A and Mic Live B) may be selected to be green when the mic is live and red
when not live OR red when the mic is live and off when not live. Press the TX Light colour button to
toggle between the two selections.
Back
This returns to the previous menu.
