H Series Bass Preamp by James Demeter 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. This preamp provides the best of both the tube and solid state world.
It features high voltage (250V) tube front end (providing all of the preamp 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. As with all Demeter equipment it is meticulously hand wired, using the finest components and assembled in the U.S.A.

After 20 years of production the Demeter Amplification Tube Bass Preamplifier is still the only musical instrument preamplifier to incorporate truly modern tube design technology with circuit features found on only the most expensive and esoteric, tube hi-fi equipment. The Preamplifier has the warmth and dynamic range that only tubes can produce, yet has lower noise specs than most solid state devices. When the preamplifier is driving a quality power amplifier, it delivers the punch and clarity of the best tube amplifiers plus the almost unlimited power of today's modern power amps.
The Tube Bass Preamplifier uses a regulated B+ power supply which provides quick transient response with extremely low noise. Regulated DC is supplied to the tube filament which gives the unit extremely low noise. We use only the finest 1/2 watt, 1% metal film resistors, polypropylene capacitors, high quality, computer grade switches, and a 7025A vacuum tube, factory selected for lowest possible noise and distortion. The Preamplifier also has a low output impedance which lowers distortion and insures proper power amplifier input matching. Custom toriodal power transformer. New single space rack mount steel chassis.
Each preamp is carefully hand wired using only the highest quality parts and tested at our factory in Van Nuys, CA. You can see as well as hear the quality and attention to detail on both the inside and out.

The H Series Tube Direct (HDI-1) is a versatile new addition to the Demeter line of tube pro audio equipment. Demeter Amplification, the originator of the first commercially available Tube Direct Box has taken the technology to a new level with this innovative product incorporating the same tube driven ultra high impedance input (27 meg ohms) found in the original Tube Direct (to prevent instrument pickup loading) and a new balanced line level output section. The unit can be used as both line level direct instrument input or as a line level driver to add tube warmth to line level digital interfaces.
The front panel features two independent channels, with seperate 1/4"
inputs, ground lift, phase preset, unity gain (+6dB with balanced output) and a tube driven (Cathode input plate output) boost mode with 20dB of boost controlled by a continuously variable volume control and a unity gain low impedance tube driven output to drive external instrument amplifiers or effects. The rear Panel features seperate TRS and 3 pin connectors for each channel. As with all H series units the power supply is fully regulated (for low noise) supplying 220v B+ to the tubes. Hand built in the U.S.A. with the finest components available.
