This listing is for a used Audio Technica ATUC-50DU. The ATUC-50DU was recently replaced with the ATUC-50DUa, but it was only due to some internal circuitry changes - the functions/features remain the same. These were removed from a working environment.
The photos are of one unit in inventory, but the unit you receive may not look exactly like the one pictured since we have multiple in similar condition. All of the units have a few minor scuffs/nicks and scratches similar to what is pictured.
There is a setup guide included for each unit.
