The AM-411 is a professional, automatic microphone
audio mixer intended for fixed installation applications.
This single rack mount package is designed to provide
high quality audio performance and easy-to-use con-
trols. Engineered from the ground up, with the commer-
cial sound systems contractor in mind, the AM-411
includes removable screw connectors for easy installa-
tion and cost-effective servicing, as well as limited front
panel user control.
The AM-411 provides high quality audio operation, a
simple interface and an easy-to-install package. For
hands-free operation in new and existing sound sys-
tems, the AM-411 makes sound system operation easy
and reliable.
When using multiple microphones, gain control
becomes essential. As additional mics are turned on,
the levels of other active mics must be reduced to pre-
vent feedback. The AM-411 gain computer continuous-
ly senses the signal from each mic and quickly distrib-
utes the available gain among the channels in use so
that you won’t miss a single word. Using patented (US
Patent number 5,652,800) Priority Control Circuitry, the
AM-411 eliminates the irritating comb filtering that often
occurs when a person speaking into a wireless lapel
mic moves close to an active podium mic. With the addi-
tion of the AM-411’s ability to link multiple units, this unit
provides even more flexibility for a wide range of appli-
cations.
