Lake People LP-F311-Q 4 Channel Microphone Pre-Amplifier

The F-SERIES from Lake People covers absolutely high-level audio products with outstanding features, best technical data and perfect craftsmanship. MIC-AMP F311-Q is a four-channel ultra-low noise microphone preamplifier with excellent audio performance and more than common features.

Ideal for "on-location" recording, bypassing insufficient mixing console preamps or "direct-to-tape" sessions. Gain is settled with costly 12-step switches and so exactly reproducible and equal for both channels. The simple and cheap gain adjustment via potentiometers we leave to the competition. The amp is mains powered via a ISC/CEE socket with either 230 or 115 V AC (internally switchable).
