GSM-1
LECTERN/PODIUM SHOCK MOUNT
FOR MINI-GOOSENECK
MICROPHONES
Description
The ASTATIC GSM-1 is a high performance lectern/podium shock
isolation mount designed for mini-gooseneck type microphones. The
ASTATIC GSM-1 will work with any mini-gooseneck microphone
that is equipped with a 3 pin male XLR connector such as the ASTATIC
200, 900 and 827 series.
The ASTATIC GSM-1 features an exclusive dual point suspension
system. The high mass metal components combined with ASTATIC's
custom formulated I.N.R. (Impact Noise Rejection) elastomer
bushings result in a highly effective compact shock isolation system
that holds the gooseneck firmly in place even on angled surfaces. Unlike
other shock mount systems, the ASTATIC GSM-1 will not allow the
microphone to "sag" or "droop", even when using longer gooseneck
microphones such as the 220, 920 and 827-17.
The ASTATIC GSM-1 features a built in quick disconnect XLR
connector, complete with 6 feet of balanced line cable. Once installed,
microphones easily plug in and out of the top of the mount. There is
never any need to access the underside of the mount or make any
adjustments when inserting or removing a microphone.

Architects and Engineers Specification
The product shall be an ASTATIC GSM-1 shock isolation mount for
use with mini-gooseneck microphones. The shock mount will feature a
dual point suspension system which holds the microphone firmly in
place yet provides superior shock isolation. The shock mount will feature
a 3 pin quick disconnect standard type female XLR connector for easy
attachment and removal of the gooseneck microphone, and 6 feet of
unterminated balanced line cable. The mount will be of heavy duty
steel construction with ASTATIC I.N.R.(Impact Noise Rejection)
custom formulated elastomer shock mount bushings. The ASTATIC
GSM-1 shock isolation mount will provide over 20 dB reduction of
transmitted impact and surface noise. The mount will be finished in
black urethane paint. The dimensions of the mount will be 2.125" (56
mm) at the largest diameter, have an overall height of 3.076" (78 mm)
and mount into a 1 1/4" diameter hole with three included wood screws.
The weight of the mount will be 14 oz. (395 grams). The ASTATIC
Model GSM-1 is specified.

Installation
The ASTATIC GSM-1 requires a minimum of 3 1/2" clearance below it
as measured from the top of the mounting surface. Once a mounting
location has been chosen, drill a 1 1/4" hole in the surface. Then temporarily
insert the mount into the hole and use it as a template to mark the
location for the three included #6 wood screws.The cable on the ASTATIC
GSM-1 is supplied unterminated. If an XLR connector is required at the
end of the cable, it can be added either before or after the mount is
installed. The cable on the GSM-1 is wired as follows:
Red to pin #2; Black to pin #3; Shield to pin #1
Installation Note
The ASTATIC GSM-1 easily retrofits into the same mounting holes of
a commonly used but less effective rubber band style shock mount that
requires a 1-3/8 inch center hole.

Microphone Recommendations
The GSM-1 can be used with all ASTATIC mini-gooseneck
microphones, including the 910, 915 and the 920 in the 900 series, the
economical 827-13 and 827-17 or our popular speciality CTM 16,
CTM17 and the CTM 18 with additional internal shock mounting and
pop filter. The GSM-1 can also be used with the 215 and 220 mini-
gooseneck microphones which feature an on-off switch and power
indicator on the base of the microphone.
