AT8491D Description
The drum mount features a patented design which uses
the drum lug to securely mount the microphone while
still allowing the drum to be tuned. The gooseneck can
be positioned vertically or horizontally for optimal
placement and a low profile appearance.
AT8468 Description
The violin mount fastens beneath the strings between the
bridge and the tailpiece to provide outstanding pickup of
violin and other stringed instruments.
AT8491G Description
The guitar mount features a rugged, thumbscrew-
adjustable clamp with pads that attaches to guitars and
other stringed instruments while leaving fewer marks.
You can adjust the clamp length between 90 mm (3.5")
and 135 mm (5.3").
AT8491S Description
The surface mount is designed for accordions and other
challenging applications. The notched mount can be
attached permanently using the accordion's grille screw
and the included adhesive silicon pad, or it can be
attached temporarily using the included fastener tape
pads. A transparent protective film is also included to
prevent damage to the instrument's finish.
AT8475 Description
The surface mounting kit for AT8491S includes two
adhesive silicon pads, two mount fastener tape pads,
two surface fastener pads, and two transparent
protective films.
Operation and Maintenance
The ATM350a requires 11V to 52V phantom power for
operation.
Output is low impedance (Lo-Z) balanced. The signal
appears across Pins 2 and 3; Pin 1 is ground (shield).
Output phase is "Pin 2 hot" — positive acoustic pressure
produces positive voltage at Pin 2.
To avoid phase cancellation and poor sound, all mic
cables must be wired consistently: Pin 1 to Pin 1, etc.
The 80-Hz low-cut filter switch on the AT8543 power
module makes it easy to switch from flat frequency
response to low-frequency roll-off. This minimizes pickup
of undesired low-frequency noise, such as from air
conditioning systems. To engage the high-pass filter,
slide the switch toward the "bent" line.
Avoid leaving the microphone in the open sun or in areas
where temperatures exceed 110° F (43° C) for extended
periods. Extremely high humidity should also be avoided.
