The KAV400xi is the replacement for the KAV300, but an unusually glamorous one. It is built into a slim line and undeniably elegant version of the Showcase type housing, with the now familiar fabricated aluminum flat panels for each surface, joined together by half-rounded solid machined end caps with a polished finish, not just on the front, where such details are most obvious, but on all four corners. The front panel is equipped with a row of small buttons for source selection and mute, and a continuous turn digitally controlled resistive ladder encoded volume control and a small display to show the current operating status. The back panel is fitted with inputs sockets for the four single ended line inputs, which includes one tape circuit with a monitor facility, and a pair of XLR sockets for a single balanced mode input. Preamp level outputs are available to drive an external power amp. Speaker connections are to stout WBT terminals. Everything about the KAV-400xi screams 'quality'.
