The NT55 circuit incorporates a three position variable PAD with 0dB, -10dB or 20dB attenuation, and a three position variable high-pass filter that enables you to step from a flat response to 75 or 150 Hz high pass filter.
The NT55 comes with two different condenser microphone heads to provide a wide variety of polar patterns. The NT55 is complemented with a diverse range of accessories to better facilitate positioning and attachment.
