Audio Technica AT8410a User manual

Description
These Audio-Technica shock mounts provide
excellent mechanical isolation while offering
unusual versatility and ease of use. Equally
adapted to cylindrical and tapered microphones,
they attenuate noise, shock and vibration
transmitted through microphone stands,
booms and fixed microphone mounts.
The AT8410a permits easy microphone insertion
and removal without detaching the mic cable;
its spring-loaded clamp holds even heavy
tapered microphones securely. The AT8415’s
light weight and low profile make it an excellent
choice for “fishpole” booms and for video use.
The AT8410a mounts directly to any stand
with standard 5/8"-27 threads, and includes a
constant-tension clutch and 180˚ swivel for
easy, positive microphone adjustment. Isolation
is accomplished with elastic shock cord.
The AT8415 is furnished with a 3/8"-16 threaded
hole for mounting to a European standard
boom. A threaded adapter is provided with the
AT8415 that allows it to mate with US

standard 5/8"- 27 threads. Also, a US standard
5/16"-18 bolt will pass through the 3/8" hole in the
bail and can be secured with the appropriate
size nut. The U-shaped mounting bail features
a constant-tension clutch and is free to rotate
360˚. Isolation is accomplished with four
chloroprene bands.
Both Audio-Technica shock mounts accom-
modate most microphones in common use.
A suspended clamp on the AT8410a accepts
any cylindrical microphone body from 16.8 mm
(about 11/16") to 28.8 mm (over 11/8"). The
“clothes-pin” jaws can also pivot to firmly
hold the tapered body typical of many vocal
mics. The AT8415 mounting bands accept
any cylindrical or tapered microphone body
from 12.7 mm (about 1/2") to 54 mm (about
21/8"). The mounting bands may be criss-
crossed for increased support or for smaller
diameter microphones.
The use of a shock mount is particularly
important in any application where wide-
range sound equipment is used and where
high-level low frequency sounds can be
expected.
The AT8410a and AT8415, which have been
extensively tested in recording studios, on
stage and on major TV network programs,
are well suited to a wide variety of applica-
tions. In the TV studio, they can isolate boom
microphones from noise generated by rack-
ing the boom extension in and out, and rapid
swiveling of the boom or head. Their small
size and open construction also minimize
shadow problems.
In radio stations, noise from console opera-
tion and microphone swivel mounts is
reduced or eliminated. In the recording
studio, effective microphone isolation reduces
leakage for better control during mixing or
re-mixing.
In sound reinforcement usage, the AT8410a
and AT8415 isolate microphones from
lecterns or tables and reduce feedback from
microphones mechanically coupled to a stage
or other resonant surface. And in live enter-
tainment, shock mounts minimize noise from
the movement of instruments as well as the
pickup of high-level energy transmitted from
nearby speakers.
Instructions
The AT8410a mounts to any stand, boom or
mount with standard 5/8"-27 threads. It is
equally effective at any combination of stand
and microphone angles. The AT8415 will
attach directly to all booms, etc., with
European 3/8"-16 threads, and to all mounts
with 5/8"-27 threads via the threaded adapter
provided. It can also be used with bolts
smaller than 3/8" if the appropriate size mating
nut is used.
To mount a microphone in the AT8410a, it is
not necessary to disconnect the mic cable.
Simply squeeze the clamp jaws open, draw
the mic cable through the slot, slide the micro-
phone into position and release the clamp.
For either model, the microphone should be
inserted until the mass on both sides of the
mount is about equal. This normally permits
the head of the microphone to extend
beyond the shock mount, free of any acoustic
disturbance, and puts equal stress on all
suspension points.
Care should be taken to provide adequate
slack in the microphone cable. A generous
loop eliminates cable noise and permits the
microphone to move freely within the shock
mount, maintaining effective isolation.
Swivel tension on the AT8410a has been
preset at the factory to permit easy adjust-
ment while ensuring positive support. It may
be tightened or loosened with a coin or
screwdriver, if desired. On the AT8415,
swivel tension is easily adjusted by loosening
or tightening the two knobs. If ever needed,
replacement shock cord for the AT8410a and
mounting bands for the AT8415 are available
from the Audio-Technica service department.
