Description:
The UA874 replaces the UA870. UA874 uses a log periodic dipole array to produce a cardioidPicks up most sound in front of the microphone and some from the sides. It is less susceptible to feedback in high volume environments.

An integrated amplifier with four gain settings compensate for varying degrees of coaxial cable signal loss.
The UA874 can be stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.
