POWER switch
The
POWER
switch is located on the rear
panel of the mixer, near the linecord socket.
Switch up to turn the mixer on, and switch
down to turn it off.
The
TAPE IN LEVEL
control ranges from off
through unity (the center detent position) on
up to +15 dB of extra gain. Note that this
control only affects the
TAPE IN
level and not
the
TAPE OUT
level (there is no tape out level
control). The
TAPE OUT
level is pre-fader
(actually pre-Master in this case) and is not
affected by the
MAIN MASTER
control.
Caution:
When using the
TAPE OUT
connectors for
recording, don’t connect
the output of the tape deck
to the
TAPE IN
connectors.
If you do,
MAKE SURE
the
TAPE IN LEVEL
control is turned all the way down or you will
create a feedback loop that will suddenly make
you
the focus of attention.

MAKING THE CONNECTIONS
Front Panel Connections
Connecting Microphones and Line-Level
Signals
Each channel has both an XLR
MIC
input and a 1/4" TRS
LINE
input. In
addition, the two stereo channels on the 408M,
408S, 808M, and 808S each have two 1/4" TRS
line inputs, left and right
. These two inputs
are summed together in the 408M and 808M,
and are routed to the left and right buses
respectively in the 408S and 808S. You can plug
a mono signal into the
LEFT
stereo input and
the signal is automatically routed to both the
left and right inputs.
Mackie mixers have 3-pin female XLR con-
nectors on all microphone inputs, so use a
male XLR connector to connect to the mixer’s
mic preamps.
The XLR and 1/4" TRS inputs are balanced
analog inputs. When connecting a balanced
signal using the XLR or 1/4" jacks, be sure
they’re wired — per AES (Audio Engineering
Society) standards — like this:
