Power preamplifier MV 400 L

audiosoundinstrumentation

Description
Microtech Gefell Generation 4 is a modular microphone system introducing an ultracompact microphone preamplifier, the MV 400 L. The MV 400 L supports multiple capsule types (M 40, M 41, M 42, M 43) and two interchangeable connectors, enabling fast adaptation to different recording and measurement tasks in professional audio and industrial applications. The modular concept improves workflow flexibility and reduces setup time.

Features

• Transistor amplifier
• LEMO® triaxial connector
• Generation 4 modular system
• Low-noise circuit design
• Modular microphone concept — interchangeable capsules
• P48 phantom power
• RFI shielded
