The A400SMXLR packages the A400SM Shock Mount with the A400XLR 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 A400XLR assembly consists of a 3-pin XLR-type (female)connector and insert. Existing A400SM Shock Mounts can be retrofitted for quick release performance with the A400XLR Connector/Insert.
