Demeter HBP1-800D

The HBP-1-800D H Series Tube Bass Pre/Power amplifier by James Demeter integrates an 800 Watt Class D amplifier, driven by Jensen Transformers, into the HBP-1 Preamplifier circuit. This unit uses the same all tube front end found in his classic VTBP-201 Bass pre-amplifier and combines it with the revolutionary H Series circuitry found in his professional audio H Series line. Utilizing the best of both the tube and solid state world, the HBP-1-800D features high voltage (250V) tube front end (providing all of the preamplifier gain and passive tone controls), a two band solid state fully parametric equalizer that is tuned for bass, a fully adjustable active effects loop with controls up front, a tuner output, a full balanced output with switchable mic or line level, both a balanced TRS line level output and an unbalanced line level output for amplifier connections and a mute switch.
