About ACSS:
ACSS (Audio-gd Current
Signal System) is Audio-gd's system for transmitting audio signals in
the current domain. This concept, first seen in 1966, we have used for
many years, and since 2006, have evolved the technology to include all
audio signals in our systems from the digital source to the power
amplifier. Since 2007, ACSS components have become Audio-gd's most
popular products |

Product Feature:
The ACSS is a non-feedback
technology made with fully discrete amplifiers. Most people know the
global
feedback design can offer better specs in test measurements, and
non-feedback can't do well in test measurements but can offer better
sound for the human's ears. Here is a conflict of the classic circuits.
But the ACSS opens a new field, it can offer a least coloration sound
which is more neutral with very low distortion and high linearity. So
it can retain the dynamics, detail and neutral sound but not sound
bright or harsh.
Massive use of high
power parts and robust regulated power supply guarantee vigorous current
output that drives most existing loudspeakers. The new ACSS module
adopted in current signal handling of C-1 Master sustains the musical signal
intact, bringing dynamic response and acoustic fidelity to an
unprecedented level.
The C-1 Master provides ACSS input and XRL input.
When C-1 Master works with ACSS preamps C-3 or C-8 or C39, it shares the
isolated control circuit of the preamp causing even better signal
matching and controlling. The fruitful result is: far higher s/n ratio
and lower distortion than ever expected.
Balanced signal throughout, an entire class A current gain circuit.
The music signal is transferred in this ACSS form till it reaches the
output stage. ACSS musical signal would be directly transferred to ACSS
signal amplification module in the amplifier for signal gain processing.
Balanced bridging circuit structure doubles not only the scale of the
circuit but also the cost.
All signal gain is under current form, achieved by the unique,
superb open loop multiple output current mirror. Current mirror that
deals with the last stage of current gain utilizes 36 pairs of high
speed and high linearity transistors. Incomparably precise and ultra-low
distortion in the gain signal is the result. The signal path is balanced
throughout and all transistors work in class A mode.
Relying exclusively on the feature of ultra-low distortion of the
very linear ACSS amplifier, the music is unbounded, euphonious and
distinct even without negative feedback.
The ultra-low distortion, independent, yet intra-complementary
front driving stage and the 0DB output stage provides the back output
stage with hyper-speed, hyper-linearity regardless of low impedance or
reactance load.
For purity of output signal, high performance regulated power
circuits are employed in the power supplied to the low voltage and gain
stage. Influence from AC fluctuation is minimized.
All regulators work in current convert mode which excels in high
bandwidth, low output impedance and great immunity against interference.
