Aux Return 4 To Cr/Phones Only; Power Led - Mackie ONYX 1640I User Manual

63. AUX RETURN 4 to CR/PHONES ONLY

When this button is up, aux return 4 is routed to the
main mix bus, just as aux returns 1-3 are. When the
button is down, however, the aux return 4 stereo signal
is routed to the CR / phones matrix instead. It does
not matter if any of the source buttons [44, 45] are
assigned, but it will be interrupted, as usual, if a solo
button [41] is engaged.
Let's pretend that you are doing a live mix to a 2-track
deck, a house PA, or both, and you want to play along to
a click track. You could run the click track directly into
the main mix, but you do not want the mixdown deck or
the audience to hear it. Therefore, you may route it to
the control room and phones output instead! Similarily,
it may be used for voice-over tracks, narration, anything
you want heard by the engineer and players but not by
the audience and mixdown deck.

64. POWER LED

This green LED will turn on when the mixer is turned
on, as a reminder of how on it really is. If it is not on,
then it is off, and the mixer becomes a rather nice
weight for keeping your morning newspaper from
blowing away in the wind.
If it does not turn on, make sure the power cord is
correctly inserted at both ends, the local AC mains
supply is active, and the power switch [2] is on.
