The TASCAM CA-AK1-AN is a cold shoe adapter that allows you to use the CA-XLR2d adapter for XLR microphones with a wide range of DSLR and mirrorless cameras. This model is identical to the cold shoe adapter included with the CA-XLR2d-C mic adapter for Canon cameras, the CA-XLR2d-F mic adapter for FUJIFILM cameras, and the CA-XLR2d-AN for cameras with 3.5mm input jacks and is sold as a replacement if the original is lost or damaged.
