R
estaurants, clubs, retailers, theme parks, and just about everyone else have discovered the power
of great sounding foreground music and paging systems. Customers stay longer and spend more
money. There is just one little problem, though... A steady upward trend in listener sophistication means
that foreground music and paging systems must now deliver a much higher level of audio quality than
ever before. Achieving this on a budget is the contractor’s challenge. Symetrix answers this challenge
with the 440 Foreground Audio Controller, a comprehensive, cost-effective mixer for high performance
installations with paging and foreground/background audio.
The Symetrix 440 provides three stereo inputs
with level-matching trim controls to accommodate a variety of program sources, such as CD
players, satellite music receivers, tuners, tape
players or TV audio. Adjustable ducking controls
allow the selected source to be attenuated by a
paging signal. Inputs are supplied for both mic
and line-level paging signals. Both inputs may be
used simultaneously for those applications needing
an emergency line-level page or a message repeater,
in addition to a typical paging mic. A music-onhold output with its own level control provides
program material without the page signal for a
telephone system.
The 440’s flexibility makes it the perfect mixer for a
wide range of system applications. The simple front
panel controls enable fast set up, and there are extra
features that greatly expand its versatility. Rearpanel insert jacks for adding external processors
(such as a Symetrix 422 AGC/Leveler), internal
jumpers for rerouting the page and program signals,
and internal adjustments for the ducking circuit
allow configuring of the 440 to exactly match the
requirements of the installation.
The 440 Foreground Audio Controller:
The complete music and paging front-end for
great sounding systems. •

440 ARCHITECTS AND ENGINEERS SPECIFICATIONS
The foreground audio controller shall
provide page-over-music capability and
shall allow the user to select between three
music inputs. The unit shall occupy a
single rack space (1U).
The controller shall provide separate miclevel and line-level page inputs. The miclevel page input shall be balanced and lowimpedance, and shall use one XLR
connector. The mic-level page input shall
also have a rear-panel pushbutton which
shall apply +15V phantom power to the
mic-level page input. The line-level page
input shall be balanced and highimpedance, and shall use one Euroblock
detachable terminal connector. A frontpanel mix control shall be continuously

adjustable from mic-level page input signal
only, to a mix of mic-level and line-level
page input signals, to line-level page input
signal only.
Three stereo line-level program inputs
shall be provided. Program inputs 1 and 2
shall use unbalanced left and right RCA
input connectors. Program input 3 shall
use balanced left and right ¼" tip-ringsleeve connectors. Each program input
shall be individually buffered, and shall
have an associated front-panel trimpot,
which provides a continuous adjustment
range from +12dB signal boost to -12dB
signal cut. Any one of the three program
inputs may be selected by a front-panel
program select control.
Remote control shall be available for
control of program selection and output
level. Remote control shall be enabled/
disabled by a rear-panel pushbutton
switch. When remote control is enabled, a
front-panel indicator LED shall light, the
front-panel program select control shall be
disabled, and the front-panel output level
control shall become a master gain limit
control.
Bass and treble tone controls shall be
provided. These controls shall act on the
combined page signal and selected
program signal or optionally only on the
program signal. The bass tone control
shall have a center frequency of 100 Hz,
and shall have a continuous adjustment
range of -12dB to +12dB. The treble
control shall have a center frequency of
8kHz, and shall have a continuous
adjustment range of -12dB to +12dB.
Rear-panel ¼-inch, tip-ring-sleeve left and
right insert jacks shall be provided to allow
external processing of the combined
paging and selected program signals, or
optionally on the program signal only.
The unit shall incorporate a priority
ducking system. When audio is present at
either page input, the selected program
signal shall be attenuated (ducked). There
shall be a duck LED to indicate that
ducking is occurring. A continuously
adjustable range control shall set the
amount of attenuation from -60dB to 0dB.
RCA connectors, and also at balanced left
and right Euroblock detachable terminal
connectors. A front-panel switch shall
allow stereo or mono main output
capability. A front-panel gain control with
a clip LED shall simultaneously and
continuously adjust the level of the left
and right main outputs.
A music-on-hold output, available at a
single unbalanced RCA connector, shall
also be provided. The music-on-hold
output shall provide a mono sum of the
selected program input, prior to any
processing. A front-panel trimpot shall
provide gain control for this signal.
The foreground audio controller shall be a
Symetrix, Inc. model 440 Foreground
Audio Controller.
The stereo main outputs of the unit shall
be available at left and right unbalanced
