  • Q & A

    The four provided screws don't seem compatible with the open holes on the bottom of the unit (threads don't match) holes in plate do line up but screws don't seem right. Please advise


    Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    What size screw comes with the AT8623 to fit into the M2 box? And do you sell the screws, or have them available to customers? I need some more to mount the boxes in a rack.


    You will use the existing screws in the bottom of the M2 transmitter. Replacements may be available through our Parts Department at
