Alto Alpha Mic Tube

This metal half-rack mic preamp, powered from an included adaptor, offers variable tube drive and has combi jack/XLR sockets on the front panel with switchable phantom power. Outputs are on both rear-panel jacks and XLRs (the jack is unbalanced), and the jack input has a 1MΩ impedance, making it suitable for passive instruments as well as line signals. Other than Gain and Drive controls, each channel has phase reverse and 20dB pad, plus an eight-segment meter.
