C-1SE

 Power amplifier
with ACSS balanced bridging technology

Supports XRL and ACSS input

The pre-drive amp is separated from the output drive amp, allowing for easy setup of a Bi-Amp system.

   What's different between C-1SE and C-1Master:
    The C-1SE has the same specs as C-1Master .
         The C-1SE has pre-drive amp separated from the output drive amp, allowing for easy Bi-Amp setup. If users buy standard C-1SE, in the future they can buy another output drive amp to set up a Bi-Amp system .
         The C-1Master is a mono power amp.
C-1Master link:             C-1Master

   Easy Bi-Amp setup:
    The pre-drive amp is separated from the output drive amp, allowing for easy Bi-Amp setup, customers only need one pre-drive amp unit and two output drive amp units to compose the Bi-Amp system.

    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, with a great many customers purchasing them in China and Hong Kong.

   Applies 48 pieces of output transistors. The capacitance of the whole machine reaches as high as 200,000 uF, four transformers (Total 1500W) core transformers. Supports 250W X2 (8 Ohms) output.

   Applies all audiophile grade components, including DALE resistors, WIMA caps, custom order NOVER (UK brand) caps, all audiophile grade input & output sockets and gold IEC socket. Applied the  roundish style chassis which had lower syntony ,between the transformers and signal amps there is a thick metal board for avoid the transformers disturb the signal amps .


   Sound Characteristics:  Very neutral and neuter, truly delivers the sound of source, doesn't add any color. Before you make a purchase with this amplifier, you must make sure you have high class source gear.

   Product Feature: Adopts ACSS parallel current transmission technique. Solid grasp and ample practices of ACSS didn't cool down our passion for perfection; we have spent over a year on tweaking the circuit to achieve even better acoustic performance.

      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-1SE sustains the musical signal intact, bringing dynamic response and acoustic fidelity to an unprecedented level.

     Lowering the price but not the quality, C-1SE provides ACSS input and XRL input. When C-1SE works with ACSS preamps C-3 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.

     The entire output stage   with 48 pcs of 15A high power audio transistors in the last output stage, it is guaranteed that most existing loudspeakers turn tame with good damping.

      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.

     Four power transformers, whose total gross power are 1500W. They are sealed independently in the metal cases, which helps block interference to the critical amplifier circuit, and provides darker yet cleaner background.

      All sockets in C-1SE, including signal input and output sockets and power socket, are of audiophile grade.
