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.

Summary

Installation

Installation Note

Retrofits same mounting holes as rubber band style shock mounts requiring a 1-3/8 inch center hole.

The ASTATIC GSM-1 is a high-performance lectern/podium shock isolation mount specifically designed for mini-gooseneck type microphones. This device is engineered to provide superior shock isolation while maintaining a secure and stable position for the microphone, even on angled surfaces. It is compatible with any mini-gooseneck microphone equipped with a 3-pin male XLR connector, including ASTATIC's 200, 900, and 827 series, as well as the 910, 915, 920, 827-13, 827-17, CTM 16, CTM 17, CTM 18, 215, and 220 series microphones.

Function Description:

The primary function of the GSM-1 is to isolate mini-gooseneck microphones from impact and surface noise that can be transmitted through a lectern or podium. It achieves this through an exclusive dual-point suspension system that combines high-mass metal components with ASTATIC's custom-formulated I.N.R.™ (Impact Noise Rejection) elastomer bushings. This system effectively reduces transmitted impact and surface noise by over 20 dB. Unlike many other shock mount systems, the GSM-1 is designed to prevent microphone "sag" or "droop," even when using longer gooseneck microphones such as the 220, 920, and 827-17.

Important Technical Specifications:

Dimensions: The mount has a largest diameter of 2.125 inches (56 mm) and an overall height of 3.076 inches (78 mm).
Mounting: It requires a 1.25-inch (31.75 mm) diameter hole for installation and a minimum of 3.5 inches (88.9 mm) clearance below the mounting surface. It is secured with three included #6 wood screws.
Weight: The GSM-1 weighs 14 oz (395 grams).
Connector: Features a built-in 3-pin quick disconnect female XLR connector on the top for easy microphone attachment and removal.
Cable: Includes 6 feet of unterminated balanced line cable. The wiring is as follows: Red to pin #2, Black to pin #3, and Shield to pin #1.
Construction: Made from heavy-duty steel for durability.
Finish: Finished in black urethane paint.

Usage Features:

Easy Microphone Connection: The built-in 3-pin quick disconnect XLR connector allows microphones to be easily plugged into and unplugged from the top of the mount. This eliminates the need to access the underside of the mount or make any adjustments when inserting or removing a microphone, simplifying setup and storage.
Secure Microphone Positioning: The dual-point suspension system ensures that the gooseneck microphone remains firmly in place, even on angled surfaces, preventing unwanted movement or "droop."
Noise Reduction: Provides significant isolation from mechanical vibrations and impacts, resulting in cleaner audio capture.
Retrofit Capability: The GSM-1 can easily retrofit into the same mounting holes as commonly used, less effective rubber band style shock mounts that require a 1-3/8 inch center hole.
Internal Stop Pin: An internal stop pin protects the rubber parts from damage during microphone insertion or removal, enhancing the longevity of the device.

Maintenance Features:

Durable Construction: Built with heavy-duty steel, the GSM-1 is designed for long-term reliability and resistance to wear and tear.
Quality Assurance: All GSM-1 shock isolation mounts undergo inspection prior to shipment, ensuring high quality and performance.
Warranty: The product comes with a Two-Year Limited Warranty, covering defects in material and workmanship. In the event of a defect, ASTATIC will, at its option, repair or replace the unit. This warranty excludes damage from abuse, misuse, unauthorized repair, or issues related to exterior finish or appearance.
No Adjustments Needed: Once installed, the design of the GSM-1 means no further adjustments are required for inserting or removing microphones, simplifying its operation and reducing potential maintenance needs.
