THE X-MIXER DIGITAL CONSOLE
Equipment Description
22
SIMPLICITY
The X-mixer console is designed for
ease of installation, ease of service, and
ease of use. The basic console has 3
metal panels, 4-5 PC boards, and an
external modular power supply. Most
ICs are socketed for ease of board level
repair. The bare minimum of surface
mount parts are used. All parts are pro-
fessional quality for high performance
and long life.
CHASSIS.
The mainframe consists of a welded
aluminum bottom chassis with an alu-
minum operator panel and VU meter
housing. The operator panel is hinged
to provide access to the main
motherboard for servicing. The VU
meter panel is hinged for access to all
connectors and adjustments for instal-
lation.
To ensure high RF shielding, all
audio wiring shields are grounded
directly to the chassis through each
connector. A ground screw at the left
rear of the chassis provides a connec-
tion point to tie the chassis to the stu-
dio technical ground reference.
MOTHERBOARD
All analog and digital audio process-
ing is accomplished on a single
motherboard. A physical layout of the
board and block diagram are provided
on a following pages.
OPTION BOARD
The standard X-MIX-14-14 console
comes with 2 mic sources, 10 stereo
analog line sources, and two AES3 digi-
tal audio sources. The X-MIX-14-22
adds an additional board to the console
to add 8 AES3 digital inputs and 2 mic

POWER SUPPLY
The supply is external to the console
mainframe to reduce hum and noise. It
is what is commonly called a “line
lump” configuration. It is a compact
module with a 6 foot AC power cable
and a 6 foot DC cable that connects to
the right rear of the console
motherboard.
The power supply has DC outputs of:
(+) 5 volts, 4 amps
(+) 12 volts, 2 amps
(-) 12 volts. 0.5 amps
Physical size: 3" x 1 3/4" x 6"
Input: 100-240VAC, 50-60Hz, 1.6A
VU METER HOUSING
The VU meter housing hinges back to
provide access to the motherboard con-
nectors and trim pots. The housing
itself contains 5 VU meters and a timer.
The VU meters are analog and are driv-
en from the motherboard with associat-
ed trimpots for level adjust.
The timer is a custom up timer with
minutes and seconds. The timer chassis
and board are attached to the VU meter
housing with two screws from behind
the face. A single cable attaches the
timer to the console motherboard
through a multipin connector.
FRONT PANEL
The front panel has three
motherboards. The first 2 boards have
the switches for the channel assign -
ments. The second board has the
switches for the control room monitor
and remote selector switches. Associat-
ed electronics on the boards drives the
switch LEDs. The monitor, headphone,
and cue pots have cables and are
plugged into the motherboard. Use of
plugs (not direct soldered) simplifies ser-
vicing of the console.
