Product Description
Designed for high-definition field production environments, the MP-1 is an ideal studio-quality mic pre for critical radio, television, and film applications.
The MP-1 is extremely durable and easy to use. With rugged mechanical and electrical construction and high-quality components, it will provide years of superb audio performance under the most punishing field conditions.
Simple to Use
The MP-1 provides up to 66 dB of clean, nearly noiseless gain. Its transformer-balance microphone preamplifier offers a two-position highpass filter, extended range, selectable peak limiter, and 48 V phantom power, ensuring superior sonic quality and freedom from interference problems.
