The A400SM, A400XLR, A400SMXLR and A99SMA are accessories that allow permanent installation of a quick-release shock mount for use with a wide variety of gooseneck microphones.
The A400SMXLR packages the A400SM Shock Mount with the A400XLR Connector/Insert.
The A400XLR assembly consists of a 3-pin X LR-type (female)connector and insert. Existing A400SM Shock Mounts can be retrofitted for quick release performance with the A 400XLR Connector/Insert.
The A400SM Shock Mount employs Shure Shock-Stopper TM construction, which decouples the microphone from the mounting surface and reduces the transmission of impact or surface noise by up to 20 dB.
The A99SMA Adaptor allows the A400SM Shock Mount to be used in installations sized for use with the A99SM Shock Mount.
