Line In; Insert Send And Return; Direct Out - Mackie SR40.8 Owner's Manual

LINE IN

Point Before: Balanced or unbalanced mic- or
line-level cable with ⁄ " TRS or TS connector,

(tip = hot, ring = cold, sleeve = shield).
Point After: Channel .
This input is similar to the MIC
but without phantom power. Both signals mix
together at the mic preamp. Mic-level signals
can be accommodated here with up to 40dB of
gain. The LINE IN is 20dB less sensitive than
the MIC input.
Do not use this input simultaneously with its
associated MIC input. Turn TRIM
and engage MUTE
before inserting or re-
moving line cables. Do not use open-ended TRS
cables (signal on tip, ring open) unless the ring
is first tied to ground (sleeve). It won't hurt
anything, it will just work better if you ground
the sleeve. Although you can connect a micro-
phone to this input, there will be less noise
when connected to the MIC

INSERT SEND AND RETURN

Point Before: Channel mic/line preamp, TRIM
, 0 / (Polarity Reversal)
Point After: EQ
.
Both the INSERT SEND and INSERT
RETURN jacks are balanced, and can also
accommodate unbalanced TS cables. Signal
feeding the INSERT SEND jack is also sent to

the INSERT RETURN jack's normalling pins.
With nothing plugged into the INSERT
RETURN jack, the (dry) send signal will be
passed along to the rest of the channel path
(this is called half-normalled).
To insert a serial effects device, simply patch
input,
from the INSERT SEND jack to the effect's in-
put, and from the effect's output to the INSERT
RETURN jack, using either balanced TRS or
unbalanced TS cables.
Since using the INSERT SEND jack by it-
self does not interrupt the channel's signal
path, it may also be used as a pre-EQ/pre-
down
Fader direct output, in addition to the
post-Fader DIRECT OUT

DIRECT OUT

Point Before: Channel signal, EQ
nel Fader
Point After: Balanced or unbalanced cable
with
input jack.
The DIRECT OUT's signal is the same as the
output of the Channel, except that the PAN
control has no effect.
These jacks can be used to feed multitrack
,HPF .
recorder inputs, as a one-channel effects send,
as a secondary sound source's trigger com-
mand, or for any other purpose that requires
the post-Fader signal of an individual Channel.
Using this jack does not interrupt the
Channel's signal path to the output section.
