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-loation" recording, bypassing insufficient mixing console preamps or " direct-to-tape" sessions. Gain is settled with costly 12-step switches and so exactly reproducable 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 !
