TL Audio Ebony A1 Tube Preamp DI
The Ebony A1 Tube Preamp is a sleek-looking discrete Class
A preamp designed to heighten your audio experience. It uses Discrete Class A
circuitry and has an optional tube stage with variable drive putting you in
control of how creamy or how cool your unit sounds.
Hand assembled in England to the highest standards, the Ebony uses stylish,
quality chrome knobs together with a high-gloss black finish to make the
exterior look just as smooth as the circuits sound. The Ebony Series have all
the features you come to expect with TL Audio, including balanced I/O, multi
input options, analogue VU metering and intuitive, precise controls. All units
are also compatible with the TL Audio DO-2 digital SPDIF interface for easy
digital connectivity with high quality conversion. A combination of supreme
quality, unrivalled sound, and stylish aesthetics: This range offers superior
analog processing to accompany a digital world.
Why Class-A?
Class A circuits are designed with constant current flowing through all of the
transistors, which is sufficient to drive the peak output required from each
block of the circuit. This ensures that every transistor is kept at its optimum
operating point, minimizing nonlinearities due to changes in current and
internal thermal effects, and eliminating the objectionable "cross-over"
distortion typical of class AB circuits.
Due to the higher steady state (or "quiescent") currents used, the power
dissipation of class A circuits is substantially higher than can generally be
handled by integrated circuits. It is also possible to design discrete
transistor circuits to operate at higher voltage rails than are available for
audio integrated circuits, adding the benefit of greater headroom and improved
dynamic range. For these reasons, there are no integrated circuits in the audio
paths of the Ebony Series.
The outstanding audio quality is reflected in the technical specification of the
units, with particularly low noise and distortion, and wide frequency response.
