Audio-Technica AT8681

The AT8681 combines the output from two microphones into one channel. The balance control attenuates each microphone by 6 dB (typical) at midpoint.

Features

• Professional XLR-type input/output connectors
• Can be installed anywhere in-line, either at the mixer input or near the microphone
• 24-48V DC phantom power and balanced cables required for operation
• Permits phantom voltage to pass on to the microphone
• Rugged steel housing
