ML4000 User Guide 17
STEREO IN. Each provides two balanced stereo
inputs which can be selected independently or
mixed into the channel, INPUT A on TRS jacks,
INPUT B on XLR. These accept line level signals.
LOCAL MONITOR OUT. Ground compensated
stereo monitor output on TRS jacks. These can
connect to a stereo amplifier/speaker system for
local monitoring.
2-TRACK IN / OUT. Line level TRS jacks to
connect to a 2-track recorder such as MiniDisc, tape
or DAT. Connect OUT to the recorder input, and IN
to the recorder output. The connections are
balanced. Link ring (cold) to sleeve (ground) when
connecting to unbalanced equipment.
MAIN OUTPUTS. Line level balanced XLR outputs
for the L, R and C main mix. Pin 2 hot. These
outputs can provide up to +23dBu maximum and
are suited to driving line level equipment operating
at nominal 0dBu or +4dBu. The C output is
available as the engineers wedge monitor feed
when the front panel mode switch is selected.
GRP / AUX / MATRIX OUTPUTS. Line level
balanced XLR outputs for Grp 1-8, Aux 1-12 and
Matrix 1-4. Pin 2 hot. These outputs can provide
up to +23dBu maximum and are suited to driving
line level equipment operating at nominal 0dBu or
+4dBu.
Note: The GRP and AUX output XLRs always
remain on their respective connectors regardless of
the setting of the front panel REVERSE switches.
INSERTS. Each of the 8 mix and 3 main outputs
has a pre master fader insert point. These provide
separate TRS jack sockets for send and return.
The mix signal path is interrupted when you plug
into the RETURN socket. You can tap off the pre-
fade signal without interrupting the signal path by
plugging into the SEND socket.
INTERCOM. Female XLR socket for connecting
the console to a ClearCom compatible intercom
system. An intercom headset is not required as the
console headphones and talkback microphone are
used. A standard 2-core shielded mic cable is
suitable.
LAMP. 4-pin XLR for plugging in a gooseneck
lamp to illuminate the control surface. Three lamp
sockets are provided along the back of the
meterpod. The right angled Littlite type is
recommended. The 4-pin XLR prevents any
confusion with the 3-pin audio connections.
