Master-2H Mono Balanced Power Amplifiers
The Master-2H is a top class power amplifier, designed without any compromises using the best components available on the market! The analogue amplifier stages of this amplifier are non-feedback and DC coupled without any opamps, all discrete. The power supplies of this amplifier are feeded by 4 transformers, 2 per channel and RCORE for preamp sections. Audio-GD uses a technique that is unique in this price range, and designed using "Diamond Cross output stages". This integrated amplifier is a real balanced ACSS solution and delivers 250W per channel @ 8 Ohm and 500W per channel @ 4 Ohm speakers. No wonder this magic amplifier sounds phenomenal! Neutral, detailed, excellent 3D staging and authority and keeps a speaker totally in control!
Master-2H has extremely high fidelity; its SQ is neutral. It will show how good or bad the recording is!
- Real Balanced ACSS Integrated Power Amp
- Applies the round-corner style chassis which has lower syntony or vibration. Between the transformers and signal amps resides a thick metal plate to avoid interference.
- Fully balanced design, the gain stages and pre-driver stages working on class A , built by discrete analog stages without any OPA or coupling caps in the signal channels.
- The output transistors stages work in high idle current state. The Diamond Cross output stage design avoids "switch distortion" as well as class A amps.
- Non- feedback ACSS analogue design
- 80 output transistors: "the King of transistors MJL4281/4302"
- Support 250W X2 (8 Ohm) output, 500W x2 (4 Ohm)
- The capacitance of the whole machine reaches as high as 260,000 uF, powered by four R cores transformers (Total 1500W)
- Completely separated design, separated power supplies for the right and left channels.
- In total 4 groups of high-quality class A parallel PSU's to power gain stages. To achieve a high S/N, the control circuit is powered with separate regulators.
- Analog inputs: XLR, ACSS
- Audiophile grade components, including DALE resistors, WIMA caps, custom order NOVER (UK brand) caps, all audiophile grade input & output sockets and gold IEC socket.
- Static mode storage control software to avoid interrupting the sound quality , the MCU output is inactive when no user operation is active.
