Overview
The MP-1 is a top-of-the-line audio device that boasts exceptional specifications. It offers an impressive 66 dB of gain, which can be adjusted in eleven distinct steps. The input and output are transformer-balanced, ensuring high-quality sound. Additionally, the MP-1 has the ability to provide either 48 volt or 12 volt phantom power. It also features a high pass filter at either 80 Hz or 160 Hz with a 6 dB/octave slope. The unit is virtually “unclippable” thanks to its built-in limiter, and has a high current line output drive. It is also highly resistant to RF interference, making it ideal for use in high-definition field production environments.
The MP-1 is designed to be both durable and user-friendly. It is powered by two AA batteries, making it easy to use on the go. Its rugged mechanical and electrical construction, along with high-quality components, ensure that it will provide excellent audio performance for years to come, even in the most challenging field conditions. Whether for radio, television, or film applications, the MP-1 is the perfect choice for those seeking studio-quality sound in a portable package.
