CardioidLauten Audio LA-320

Cardioid Tube Condenser Microphone

The Lauten Audio LA-320 is a large-diaphragm tube condenser mic from Lauten’s entry-level “Series Black” line, which incorporates the LA-120 and LA-220. All Series Black microphones are made in China.

The mic’s capsule is a K67 style, presumably 32mm O.D., and likely metallized on only one side as is common to Cardioid-only microphones.

The tube is a Chinese made 12AX7. The circuit uses an output transformer.

The LA-320 has both low- and high-cut filters, which is unique among mics in this price range. The filters are independently switchable from the front of the microphone and operate at 120Hz and 12kHz respectively.

The microphone comes with power supply, 5-pin cable, and spider shock mount all packed inside a padded briefcase.
