AS 4+3
Automixer
Description
The AS 4+3 is an easy to use and affordable gating
automixer that can easily be integrated into any sound
reinforcement, teleconferencing or recording application. The
AS 4+3 has four balanced mic inputs and three unbalanced
line inputs, as well as, one balanced line output and one
unbalanced record/line output.
Each of the four mic inputs have integrated and adjustable
compressor/levelers making the AS 4+3 an automatic level
control system. The compressor/levelers can help maintain
consistent audio level despite various signal strengths that
may be present at the microphone inputs. NOM attenuation
decreases by 3dB every time the number of in-use mics
doubles. A switcheable ducking function will attenuate all
other inputs by 12dB when signal is present at mic input #1.
Dipswitches on the rear panel allow for the line inputs to be
exempted from the automix and/or ducking functions in the
mixer.
The AS 4+3 was designed to operate with various types of
microphones. Dip switches on the rear panel allow for
24 volt phantom powering of condenser microphones. The
preamp gain range for the mic input signal are switcheable
on the rear panel while front panel controls provide fine
adjustment of input and output signals for an exact match
into whatever component follows the AS 4+3.
More than one AS 4+3 may be daisy chained via
expansion port connection incorporating the automix
functions so that all will work together as one unit.
