Lake People LP-F311-D 2 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-D is a two-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). Take a look at ADC F444 to create a second-to-none compact recording device !

Features

• Dual-channel ultra-low-noise microphone preamp with audiophile-grade circuitry
• Precision gain control via 12-position stepped switches (0 to +66 dB in 6 dB increments)
• Electronically balanced XLR inputs and outputs for pristine signal integrity
• Unbalanced RCA outputs for flexible connectivity
• Switchable 48V phantom power for each channel
• Built-in Lo-Cut filter at 70 Hz (12 dB/octave) eliminates low-end rumble
• Phase reverse switch for correcting polarity issues
• 7-segment LED meter per channel (-36 dBr to 0 dBr), internally calibratable
• Wideband frequency response from 5 Hz to 150 kHz (-3 dB)
• Internal power supply with selectable 115/230V operation
