PHAB
The Phædrus Audio PHAB microphone preamplifier is essentially the front-end of a single-channel
of the LONDON console, in which PHILHARMONIC modular-amplifier is combined with a rotary
attenuator, switchable pad, high-pass filter and gain-switching circuitry similar to that employed in
the famous sixties consoles.
PHAB microphone preamp’ and PHAME instrument preamp’
PHAME
The Phædrus Audio PHAME is a development of the PHAB in which the very high input impedance
of the input pentode valve is exploited to provide a very high quality instrumental preamplifier.
PHI
The Phædrus Audio PHI DI-Box is a product designed for a
wide range of applications; from live use to the recording
studio. Partnered with the PHAB it provides a solution for
almost any instrumental or vocal preamp' application.
Construction - or star earths (grounds) and
curly tracks
Given their vintage, the V72 amplifiers and the REDD.47 amplifiers were buil t on a metal chassis,
with the components hardwired onto tag-strips. Al though Phædrus Audio equipment uses printed
circuit boards to ensure consistent performance and reliability, the equipment follows "classic"
practices such as star earths and "natural contour" tracking, just like hook-up wire.
Every Phædrus Audio PHAB, PHAME and PHI product is hand assembled and individually tested. A
test pro-forma is provided with every unit. Phædrus Audio offer comprehensive service for
products both inside and outside of their warranty period.
