Both the
SEND
and
RETURN
jacks are balanced,
but can accommodate unbal-
anced TS cables. Signal
feeding the
SEND
jack is also
sent to the
RETURN
jack’s normalling pins.
With nothing plugged into the
RETURN
jack,
the (dry)
SEND
signal gets passed along to the
rest of the mix output’s path. (The jacks are
half-normalled.)
To insert a serial processor (such as a
graphic equalizer or compressor/limiter), simply
patch from the
SEND
jack to the effect’s input,
and from the effect’s output to the
RETURN
jack, using either balanced TRS or unbalanced
TS cables. Since using the
SEND
jack by itself
does not interrupt the mix signal path, it may
also be used as a pre-Fader direct output.
HEADPHONES
Point Before:
INSERT
(
HEADPHONES
)
.
Point After: Your favorite headphones (one set
only per jack, conventionally wired: tip = left,
ring = right, sleeve = shield.)
WARNING: The
SR40•8’s stereo phones
jack will drive any stan-
dard headphone to very
loud levels. When we say
the headphone amp is loud, we’re not kid-
ding. It can cause permanent ear damage.
Even intermediate levels may be painfully
loud with some earphones. BE CAREFUL!
Always turn the
PHONES
level
all the
way down before connecting headphones. Keep
it down until you’ve put the phones on. Then
turn it up slowly. Why? “Engineers who fry their
ears find themselves with short careers.”
The SR40•8’s headphone amplifiers will
drive headphones of any impedance, but for
best results (loudest volume), use 60-ohm
headphones.
L-INSERT, R-INSERT (HEADPHONES)
Point Before:
PHONES
level

Point After:
HEADPHONES
and
MONITOR
outputs
.
Per side, these unbalanced inserts share the
send and return on the same jack; tip = send
(to device), ring = return (from device),
sleeve = common ground.
This particular pair of insert points has only
one function: Patch in a digital delay here and
adjust the delay time so it matches the delay
caused by the distance between the console
and the stage speakers. This eliminates the
slap-back effect of hearing the console first
and then the speakers.
