Return Talkback 1
The RTB switch activates the signal path of the studio live room return
talkback microphone. RTB is latching and can remain on throughout the
session. This function enables two-way communication between the
engineer and instrumentalists who may not have a vocal microphone in the
studio live room. Return talkback is connected via an XLR connector on the
rear of the console. The return talkback level to both M2 LS outputs and the
RTB O/P XLR can be adjusted with the trim level control to the top right of
the RTB button.
Further information on Return Talkback Options can be found on page 47
In order for the RTB button to function, Return Talkback must be activated
from the services screen under TB>RTB ENABLE: [Y]
Talkback Footswitch 1
The 8424 Console also has a talkback on/off footswitch control that is
accessed via the DC REMOTES D-sub connection on the back of the console
(Pin 4). Once connected the footswitch will run parallel to the CUE TB on the
console surface. CUE TB and DIM will flash to indicate engineer external
talkback active.
