The End Of Ear Fatigue
Introduction
For some years, now, SPL has addressed this issue in all of its master-
ing product series through its own specifically developed 120 volt tech-
nology. Consoles and signal processors of the SPL Mastering Series
appear as central elements in installations of today’s most renowned
mastering houses (z. B. Bob Ludwig’s Gateway Mastering & DVD in the
USA, Simon Heyworth’s Super Audio Mastering in Great Britain or the
Galaxy Studios in Belgium).
This 120 volt technology is based on discrete operation amplifiers
from SPL’s own production, developed and perfected over many years
by SPL’s co-founder and chief developer, Wolfgang Neumann. These
SUPRA OPs work with high-performance semiconductors in Class A
technology at a symmetrical voltage of +/-60V.
In the Phonitor nine SUPRA OPs are employed. The SUPRA OPs have a
Signal To Noise Ratio of 116 dB and offer a nearly 34 dB headroom – that
yields an unequalled 150 dB dynamic range.
The musical result is not to be mistaken: Regardless of the monitor-
ing means, regardless of how loud you monitor – the Phonitor always
remains a distant, impartial factor unaffected when used to capacity
and beyond being overloaded. The phase stability is always perfect,
its THD next to immeasurable. The Phonitor’s SUPRA OPs cannot be
stressed in the most stressful circumstances, and for precisely this
reason its musical sound is always relaxed and spacious. All frequen-
cies are reproduced in balance, basses are stable and tight, mids are
clear and differentiated and highs remain transparent and soft.
Such supreme and heretofore unreachable neutrality in audio repro-
duction is the direct consequence of our technical approach and basis
in 120 volt technology: Possible disturbances from such as noise or dis-
tortion are so slight that we even arrive at the boundaries of the best
measuring equipment, and what remains is quite simply unaltered mu-
sical sound.
