Typically, the engineer sends the main mix to an audi-

other than the main mix in the control room or head-

phones? With the Onyx 1640i, the engineer has several
choices of what to listen to. This is one of those tricky
parts, so buckle up.

42. HEADPHONE OUTPUT

This 1/4" TRS connector supplies the output to your
stereo headphones. It is the same signal that is routed
to the control room outputs [16], as determined by the
control room/phones source matrix [44, 45]. The vol-
ume is controlled with the phones knob [48], right next
to the control room knob [47].
Whenever a solo switch [41] is engaged, you will
only hear the soloed channel(s) in the headphones.
This gives you the opportunity to audition the channels
before they are added to the main mix. (Solo signals
reaching the headphones are not affected by the chan-
nel level or main level, therefore turn down the phones
R
level first, as soloed channels may be loud.)

The phones output follows standard conventions:

with some headphones. BE CAREFUL! Always turn the

necting headphones or pressing a solo switch, or doing
anything new that may affect the headphone volume.
Then turn it up slowly as you listen carefully.
