Beskrivelse av varen
Tilstand: Som ny - Ikke synlig brukt
The PRO MPA is one of the finest microphone preamplifiers available. Developed in partnership with studio and live sound engineers, the PRO MPA possesses ‘the sound’. A member of the A R T Reference Series, the PRO MPA was designed and constructed with the absolute best components, assuring a lifetime of quiet, reliable performance. The PRO MPA (Microphone Pre Amplifier) is a multi-purpose tool for audio engineering and recording. Enclosed in a 2U (3.5″ high) rack-mountable chassis are two independent cha nnels of analog microphone preamplifiers designed to work seamlessly with any recording, sound-reinforcement, or electronic instrument setup. A R T’s PRO MPA circuitry is a hybrid design utilizing the latest and most advanced solid state and tube technology. Using a transformerless design throughout, the PRO MPA maintains exceptional signal integrity and extremely low noise. The Active balanced input utilizes a hybrid, triple-differential transistor design, providing extremely low noise and excellent CMRR.
A second stage 12AX7A tube running on a regulated DC voltage provides an additional 40 dB of gain. The design causes the tube to overload before the input or output stage. This allows the user to manipulate the tube gain to meet their sonic requirements. The 1/4″ input has a high impedance, which prevents the loading of any device connected to it and makes the PRO MPA perfect for DI or line level applications. Each channel of the PRO MPA features independent input and output level controls and a variable high pass filter. Because of the filter design, the high pass circuitry allows the user to gently remove unwanted rumble and low frequency information without changing the overall sonic character of the input signal. Additional features include: +20dB gain, phantom power and phase reversal switches with LED indicators. Internal power supply, balanced and unbalanced connections and a full five year warranty round out an extremely attractive yet cost effective package.
