Stereo Preamp Mixer
STEREO PREAMP/MIXER
®
The ADVANTAGE SPM412e Stereo Preamp/Mixer provides four stereo line inputs, one mic/line input, and two
independent outputs. With input source selection, automatic page-over muting, and remote control functions, the
SPM412e is ideally suited for applications such as restaurants, bars, meeting rooms, aerobics studios, and school
gymnasiums. The SPM412e is extremely versatile, yet cost-effective, and is easy to install and operate.

ARCHITECT'S & ENGINEER'S SPECIFICATION
(available on floppy disc)
The stereo preamp/mixer shall provide four unbalanced stereo line inputs and
one differentially balanced mono mic/line input. Each stereo line input shall
include a rear panel screwdriver adjustable level control, and shall be capable of
accepting either -10dB or +4dB signals Stereo line inputs 1-4 shall be provided
on female RCA connectors. Four front panel push-buttons, with associated LED
indicators, shall allow selection of stereo line input signals. The mic/line input
shall have 60dB of gain, and shall include a rear panel screwdriver adjustable
40dB trim control, a 30dB pad switch, a peak indicator, and a front panel rotary
level control. The input shall be able to accept low-impedance microphone
signals or line-level signals. A rear panel switch shall activate +24 volt phantom
power for condenser microphones. The mic/line input shall be provided on a
plug-in barrier strip, with additional screw terminals available to program talkover
muting of the stereo line signals. Talkover muting may be triggered either by an
external switch or by signal present at the mic/line input.
A balanced stereo main output and a balanced mono zone output shall be
provided on plug-in barrier strips. The stereo main output shall include front
panel rotary controls for bass, treble, and balance, with three front panel pushbuttons providing level up, level down and mute functions. Nine front panel LED
indicators shall display the relative level setting. A stereo main output limiter
circuit shall include a screwdriver adjustable rear panel threshold control and an
LED indicator. Rear panel switches shall allow the stereo main output to operate
in mono, and the treble & bass controls to be defeated. The mono zone output
shall include a front panel rotary level control. Internal jumpers shall allow
mic/line input and stereo line input signals, as well as talkover muting, to be
assigned to the stereo main and/or mono zone outputs. Internal trim controls
and jumpers shall allow talkover muting levels to be adjusted independently for
the stereo main and mono zone outputs. Internal jumpers shall assign mic/line
input signal pre or post treble & bass, and pre or post main level.
Optional remote control, by infrared transmitter/receiver, wall-mount panel,
custom panel, or third-party controllers, shall affect stereo line input selection and
stereo main level/mute functions. Wall-mount Controller shall override front
panel control. Remote controls may be wired up to 2000 feet from the
preamp/mixer, and the infrared transmitter shall operate up to 30 feet from the
receiver. Default power-up settings shall be programmable for sources & level.
The stereo preamp/mixer shall have a Frequency Response of +0/-0.5dB from
20Hz to 20kHz at +4dBu. THD + Noise shall be less than 0.1% from 20Hz to
20kHz at +4dBu. Output Noise shall be less than -85dBu from 20Hz to 20kHz at
nominal levels. Microphone Equivalent Input Noise shall be less than -125dBu.
Power Consumption shall be less than 10 Watts. Dimensions shall be 1.75" H x
19" W x 7.25" D. Weight shall be 6 lbs. Warranty shall be 5 years. The unit
shall be CE marked with a UL / C-UL listed power source, and shall incorporate
AES recommended grounding practices.
®
The stereo preamp/mixer shall be an ADVANTAGE SPM412e.
