418

EIGHT CHANNEL PERSONAL MIXER WITH EQ AND DIRECT OUTS

The ART Model 418 Eight Channel Personal Mixer
provides eight channels of basic mic/line mixing
capability in a convenient, easy-to-use rack format.
The unit features a selection of XLR mic and 1/4 inch
unbalanced line inputs with LEVEL and TONE controls.
Additionally,phantom power is also available,and is
switch-selectable on each mic input. Each line input
can be converted internally to a line output for that
channel.

Two 418’s can be patched together via their Pre-Fade
Out and Aux in jacks so that one is slaved to the other
for up to 16 channels with one master level.

Usage

a) Connect the AC cord to a grounded 120VAC socket.
b) Connect low-impedance mics to the XLR sockets.
c) Connect shielded unbalanced line inputs to the

1/4" jacks.

d) For mic channels requiring phantom power (for

condenser mics) set the appropriate PHANTOM
POWER DIP switches in the down position. Do not
engage phantom power on a channel unless it is
for a condenser microphone.

e) Switch on the power and set the MASTER LEVEL

to the 1/2 way setting,then adjust the channel LEVEL
controls as required for the best mix and level. Adjust
the channel TONE controls for the desired balance of
lows and highs. Center setting is approx. neutral.

f) Re-adjust the MASTER LEVEL as required for best

signal level.

g) To inter-connect two 418s for 16 channels,run a

shielded, unbalanced patch cable from the PRE-FADE
OUT jack on mixer A to the AUX BUS IN jack on mixer
B. Note that only the MASTER LEVEL on mixer B will
now function.

h) To convert the line input on a channel to a line output,

unplug the 418’s AC cord from the wall and remove
the top plate. Inside you will see a row of jumpers.
Move the jumper for the desired channel to pins 2
& 3. Now that channel’s line input is converted to a
line output and may be connected to the input of
another mixer. Do not connect the output of a mixer
or any other signal source here now or the unit may
sustain damage. Be sure to replace the lid before
plugging the unit back into the AC socket.
