TALKBACK Section
The talkback feature allows the engineer to communi-
cate with the talent either through the PHONES output
[30], the AUX 1-4 outputs [62], the AUX 5-6 outputs,
or the SUB 1-4 outputs [60]. A talkback microphone is
built into the Onyx 1640, or you have the option of con-
necting an external microphone at the TALKBACK MIC
XLR [51] connector on the rear panel, which may be
preferable in live or noisy situations.
24. Internal TALKBACK MIC
This is where the built-in talkback microphone is located.
This is an omni-directional dynamic microphone, so it will
pick up your voice from anywhere in front of the mixer.
The ASSIGN TO MAIN MIX button [19] routes the
stereo mix from the optional FIREWIRE card to the
main mix bus.
This gives you the fl exibility of monitoring the TAPE,
SUB 1-4, or FIREWIRE signals as they appear at the
MAIN OUT rather than at a point just after their respec-
tive level controls.
19. ASSIGN TO MAIN MIX (FIREWIRE)
Let’s say you’re doing a live show. Intermission is
nearing and you have a playlist of MP3 fi les on your lap-
top you want to play during the break. Get the optional
FireWire card and engage the ASSIGN TO MAIN MIX
button to play your MP3s directly from your computer,
into the MAIN MIX.
20. CONTROL ROOM Knob
This controls the volume at the C-R OUTs [59], from
off (
∞) to maximum gain (MAX).
21. PHONES Knob
This controls the volume at the PHONES output [30],
from off (
∞) to maximum gain (MAX).
22. TAPE IN Knob
This controls the volume at the TAPE input [58], from
off (
∞) to maximum gain (MAX).
23. TAPE TO MAIN MIX
Push this button in to route the TAPE IN signal to the
main mix bus.
WARNING: Pushing in the TAPE
TO MAIN MIX button can create a
feedback path between TAPE IN and
TAPE OUT. Make sure your tape deck
is not in record, record-pause, or input
monitor mode when you engage this switch, or make sure
the TAPE IN knob [22] is turned all the way down (off)
when recording.
