INVOTONE SM150B

The INVOTONE SM150B is a large diaphragm condenser microphone with cardioid characteristic that excellent for broadcasting, recording techniques (Studio) or theaters and other professional audio applications is suitable. The steamed up high-gold diaphragm with low self-noise is able to accurately reproduce even quietest sounds even when high-frequency signals that can be reproduced by conventional large diaphragm microphones not readily available. A switchable 10dB pad and a low cut filters suppress unwanted low bass frequencies in live mode and allows with ease processing high sound pressures across the entire frequency spectrum. The SM150B is therefore ideal for percussion and guitar recordings used. The integrated 3-layer mesh cage protects the microphone from accidental damage. Supplied with a recording spider and windscreen foam are included. The whole thing comes in a handy case with aluminum profile.
