Portable Automatic 4-Channel Mic Mixer with IntelliMix
A portable automatic mixer, the FP-410 is equipped with
Shure’s patented “IntelliMix” to deliver flawless automatic
microphone mixing. The remarkable operating concept
behind the FP-410,“Intellimix” combines three unique
functions: Noise-Adaptive Threshold, MaxBus and Last
Mic Lock-On, to provide greater gain before feedback,
reduce pickup of ambient noise and eliminate comb filtering effects. Ideal for video production, broadcast, conference recording
and field production, the FP-410 is also useful for convention facilities, hotels and sound installations.
MaxBus:
Eliminates the poor audio quality that results
when a speaker is picked up by more than one
microphone.It does this by controlling the
number of microphones that may be activated
for a single sound source.With MaxBus, one
talker will activate only one FP-410 channel,
even if multiple microphones are “hearing”
that talker.
Last Mic Lock-On:
Maintains a seamless audio mix by keeping the
most recently activated microphone open until
a newly activated mic takes its place.Without
this function, a long pause in conversation
might cause all mics to turn off and sound as
if the audio signal has been lost.With Last
Mic Lock-On, background ambience is always
present.
◆ Four XLR-balanced inputs and two XLR-
balanced outputs. Each can be individually
set for microphone or line-level signals.
◆ Any high quality, low-impedance,balanced
mic (dynamic or condenser) can be used,
including wireless and shotguns
◆ Additional FP-410 mixers can be intercon-
nected. Linked systems can contain over 25
mixers and 100 microphones.
◆ Front-panel channel gain and master con-
trols operate as in conventional mixers.
◆ Selectable hold time keeps microphones on
during short pauses in speech.
◆ Automatic gain adjusts as additional
microphones are activated.
◆ Wide, flat frequency response and low dis-
tortion up to +18 dB output.
◆ LED indication of mic channel mix levels,
output level and limiter action.
◆ Automatic muting prevents annoying
thumps and loudspeaker damage when the
FP-410 is turned on and off.
◆ Separate monitor input and tape output
(aux-level) jacks.
◆ Front panel headphone monitor jacks with
level control.
◆ 48-volt phantom powering for condenser
microphones.
◆ Operates on AC or two 9-volt batteries.
◆ Includes optional bumpers (feet) for use
on horizontal surfaces; a short cable for
linking two FP-410’s; and a rack mount kit
for installation in a 19˝ rack.
“IntelliMix”—How it Works
Multiple miking situations—with a number of talkers
participating—have always presented problems for the audio
technician. If too few mics are used,the coverage of each talker
may vary, with one talker (nearest the mic) being louder and
clearer than the next.Talkers farthest from the mics will sound
“echoey”and reverberant, as very little of the direct sound from
their mouths reaches the microphones. If too many mics are
used, there’s more background noise and reverberation pickup,
as well as less gain before feedback if a sound reinforcement
(PA) system is used.
It’s somewhat like having multiple video cameras all focused on
the same subject. If the camera signals are combined, the result
is a blurred image.When multiple microphones are open for a
single talker, the result is a blurred audio signal. But it’s often
not practical for someone to turn mics on when they are
needed and off when they are not.The answer is the FP-410.
The FP-410 automatically attenuates any microphone not being
used, greatly reducing excess reverberation and feedback problems.
When a new talker starts, the FP-410 immediately selects and silently
activates the most appropriate microphone.“IntelliMix”electronic
processing enables the FP-410 to provide clear, natural voice pickup.
The FP-410 significantly reduces the problems of “boomy”or
“muddy”sound, insufficient sound level (because of feedback or
“howling”), and operator errors. In fact, errors are virtually eliminated
because the FP-410 doesn’t need an operator or technician for
continual adjustment—once set up,it is completely self-sufficient.
The FP-410 has numerous applications in video production and
audio recording, broadcasting, and sound reinforcement. In any
speech pickup application with multiple microphones, the FP-410
dramatically improves audio quality. Switching from manual to
automatic operation allows an individual’s voice to rise above back-
ground noise and reverberation to become clearer and more intelligible.
Noise-Adaptive Threshold:
Distinguishes between constant back-
ground noise (such as air-condition-
ing) and rapidly changing sound (such
as speech). This function continuously
adjusts the activation threshold so only
speech levels that are louder than back-
ground noise will activate an FP-410
channel.
