November 2001 H O V L A N D H P - 1 O O FEATURES For over 20 years, Hovland Company has pursued the ideal of recovering all the artistry and emotion embedded in great recorded musical performances. Our goal is audio reproduction with a live and tactile quality which envelops the senses and places the listener into a unique and dimensional moment. The inspiration for our products flows from a desire to accurately convey not only the details and dynamics of music, but also its passion, poetry, grace, grit, hope, daring, and timelessness. The creation of Hovland components is an organic process involving thousands of subtle comparisons and judgements. Circuits and models are fabricated and continually refined. Each element and its interaction with the whole is carefully considered always referenced to the musical ideal. The HP-100 preamplifier embodies our philosophy of fidelity to the art, ably enhancing any high quality music system. It is an enduring composition and the overture to a symphony of fine components. Maestro! Full-featured vacuum tube stereo preamplifier, available as a line stage or with an integral phono stage for either high or low output phono cartridges. Either phono section can be added to a line stage model at any time. Fully hand assembled to insure the highest level of craftsmanship. Ultra selected, best quality passive components used in critical applications, including Hovland Company s acclaimed MusiCap ¨ film-and-foil capacitors. Volume is controlled by a custom-made 31-position silver contact stereo level attenuator switch, with 2 dB steps. Critical signal wiring is Hovland Generation 3 shielded silver plated interconnect and Music Groove 2 phono wire. Rigid, all alloy monococque chassis isolates the three main circuit boards, preventing interaction between phono, line, and power supply circuits. Polished and anodized exterior plates; polished, nickel plated face panel. Power supply incorporates proprietary transformers and filter capacitors. Noise-free, timed muting circuit protects other system components when the preamplifier is turned on or off. Hard gold-plated RCA jacks with collet-type female pin sockets. Other features include: eight selectable inputs plus separate Tape Monitor (9 inputs total); stepped balance switch with 1 dB steps (out of circuit in neutral position); Stereo/Mono and Mute switches.
