Kenwood DPX-4021

デュアルサイズCD/カセットレシーバー: Light it up and you understand immediately. The analyser runs in three colours at once, red across the top, blue underneath, a white column tracking through the middle, and the equaliser curve names are printed into the display mask so the one you are using glows out of the dark while the rest stay hidden. Thirteen main analyser patterns with names like Laser, Amoeba, Strobo Light, Rain Drop and Magnet, and a second independent sub analyser layer behind them with four more, Canyon, Vibroscope, Champagne and Peak Bound. Set them in combination and no two of these look the same. What makes it rarer still is what sits behind the fascia: a CD slot on top and a cassette deck underneath, which is a combination that only existed for a few years. The tape side is not an afterthought either. Dolby B, a metal and chrome position selector, auto reverse, DPSS to skip up to nine tracks, blank skip to run past dead air, and index scan to sample ten seconds of everything. The CD side takes CD-R and CD-RW. Then there is the DSP with six sound fields and an equaliser that works two ways: Easy gives you nine named curves at three strengths, and Pro opens it up into three parametric bands with selectable centre frequencies and Q. 47W x 4, Digital Pulse Axis Control on the badge, and a silver fascia that has aged better than it had any right to.
