T
he X-mixer console sits on top of the
studio furniture countertop. A minimum of
13 inches of vertical clearance above the
countertop is required to open the operator
control surface to its service position.
The X-mixer console consists of:
... The 14-input mainframe
... Power supply
... Tool Kit
... Audio and Logic Connector Kit
... Spare Parts kit
... CDROM
Custom engraving on the channel On/Off
button caps and colored fader knobs are
available. See Accessories for details.
INSTALLATION NOTE:
mixer near intense electromagnetic hum
fields, such as those from power transform-
ers and audio amplifiers using inexpensive
power transformers operating in or near
saturation, as this can impair console per-
formance. Route audio cables to achieve
maximum practical distance from all AC
mains wiring.

CONSOLE CONFIGURATION

The X-mixer console is a compact yet fea-
ture packed design. The compact size gives
the operator easy reach to peripheral equip-
ment located to the sides of the console.
Channel Assignment
Any input can be assigned to any of the
fader channels of the console. Basic assign-
ment can be made using DIP switches on
the motherboard. Advanced assignment can
be made using PC setup software.
The Meter Panel
Five analog VU meters provide level mon-
itoring for all three of the console output
buses: Pgm, Aud, and Mono. An event
timer is also located on this panel.
Connector Access
All audio and logic connectors are located
on the motherboard underneath the VU
meter housing along the rear of the console
mainframe. Simply fold back the VU meter
housing for fast and easy access to the con-
nectors.
In most installations, the wiring is
dropped into the cabinetry through access
holes in the floor of the mainframe along the
back of the console. Console and wiring
access dimensions are shown below.
Internal Control Access
The console's trimpots and DIP switches
are located below the VU meter housing and
can be adjusted but raising the housing.
Power Supply
The console power supply is external to the
console to reduce 60 cycle radiated hum. It is
a design that is commonly referred to as a

"line lump." This is a fully encapsulated,
non-user serviceable module with a 6 foot
AC power cord on one end and a DC power
cord with connector on the other end. The
DC power connector plugs into the console
motherboard under the VU meter
AC GROUND NOTE:
AC safety ground in any way. Doing so may
provide a potentially dangerous condition
to the operator.
GROUNDING & SHIELDING
The broadcast facility's technical ground
should only connect to the mainframe
chassis ground stud located at the left rear
of the console mainframe under the VU
meter housing. Terminate the facility's
technical ground wire in a crimped lug.
Connect the audio shields at both the
console and the peripheral when all system
components share a common ground
G
potential and are using isolated-ground AC
outlets individually tied back to the main
technical ground.
If isolated-ground AC outlets are not
available, connect the cable shields at the
console end only. The shields should be
floated (left unconnected) at the peripheral
device. Ensure the peripheral devices con-
nect to a clean ground through their power
cords, or through separate ground wires to
the facility's technical ground.
AUDIO GROUND NOISES:
up is generally electrostatic-such as capaci-
tive coupling between an audio line and a
power line. Do not route audio lines in the
same wireway as an AC power line.
