2.4Microphone The PERCEPTION 820 TUBE is a high quality, true condenser microphone with a 1-inch dual large-diaphragm transducer.

What sets it apart from other condenser microphones is that it uses a vacuum-tube pream- plifier. Unlike conventional solid-state electronics, a tube preamplifier adds even-order har- monics to the signal. Although these are low in level, they create a rich, warm, three-dimensional sound. This characteristic in conjunction with the typical response of the large-diaphragm transducer will give your recordings a degree of warmth and “musicality” that is difficult to achieve with solid-state microphones.

The microphone incorporates a carefully selected ECC 83 tube. If the tube needs replacing, you may alternatively use a 12AX7 tube. This type is similar to the ECC 83.

Other features of the PERCEPTION 820 TUBE include:

Selectable polar patterns: The microphone’s transducer uses a dual diaphragm. This sophisticated technology allows you to select the optimum polar pattern (cardioid, om- nidirectional, figure eight, and six intermediate patterns) for every application.

Gold-sputtered diaphragm: The diaphragm is made of a plastic foil that is gold-sput- tered on one side only to prevent shorting to the back electrode even at extremely high sound pressure levels.

All-metal body: The all-metal body adds to the rejection of RF interference so you can use the microphone near transmitter stations and along with wireless microphones or other communications equipment. The extremely rugged, heavy body and sturdy front grill protect the microphone from damage from tough handling on stage.

High headroom: Capable of handling sound pressure levels up to 155 dB and built to resist high temperatures and humidity, the microphone will give excellent results in a wide range of applications.

2.5Remote Control Unit The Remote Control Unit delivered with your microphone

provides the filament and plate voltages for the vacuum tube,

supplies the polarization voltage for the transducer,

lets you select one of nine different polar patterns,

provides a 20-dB preattenuation pad, and

allows you to switch in a bass cut filter.
