AV ESSENTIALS AV-2
The AV-2 is a superior low noise, electret condenser cardioid surface mounted boundary microphone. It has been redesigned with improved RF immunity to greatly reduce susceptibility to radio interference from GSM based cell phones, PDA/cell phones with walkie-talkie capability and other similar devices. It is ideal for use on altars, conference tables, stage floors, or television productions.
The AV-2’s electronics features an advanced transformerless design and is self-contained to eliminate the need for mounting any external boxes. The cardioid pickup pattern minimizes annoying feedback when used close to sound reinforcement speakers and monitors, while reducing the pickup of unwanted off axis sounds. The integral 80Hz, 12dB/octave high-pass filter removes unwanted low frequency energy.
The die cast zinc base and double layer perforated steel screen construction makes this microphone extremely rugged. The AV-2 can also be permanently mounted on most flat surfaces with the supplied wood screws. The AV-2 comes with 30 feet of high quality microphone cable that has a miniature 3 pin connector on the microphone end and a standard professional XLR type connector on the opposite end. The AV-2 will operate with any equipment that supplies standard 12, 24 and 48 volt phantom power.
