In the years since Harman Kardon engineers invented the high-fidelity receiver, we have taken to heart the philosophy of bringing the joy of home entertainment to as many people as possible, all the while improving performance and adding features. The HK 3390 offers the best in traditional analog two-channel audio, including a 30-preset AM/FM tuner, an integrated phono preamplifier for enjoying your vinyl library and a tape monitor loop that lets you listen to your tape recordings as they’re being made when used with a three-head tape deck. If high-performance audio reproduction weren’t enough, we’ve added composite video switching. Use the included audio/video cable to connect your iPod (not included) or other portable players to the HK 3390, or just enjoy your favorite television programs in stereo without firing up your main home theater. Whether listening to an LP record pressed last century or watching a movie you downloaded to your digital media player last night, your new HK 3390 delivers the powerful, detailed performance you’ve come to expect from Harman Kardon products. To obtain the maximum enjoyment from your new receiver, we urge you to read this manual and refer back to it as you become more familiar with its features and their operation products.
