Audio-GD Master-2A / Master 2A - Balanced Mono Amp 100W Pure Class A Design Non Negative Feedback

- 150W at 8 ohm/ 600W at 2 ohm
- Real Balanced ACSS Non Negative Feedback Power Amp
- Supports XLR and ACSS inputs
- Applied "Linear Fidelity" Technology
- Soft Start Power Design
- 80 pcs output transistors

******** PLEASE NOTE ********
The Master 2A is a 100W pure class A power amp, when it working , it can achieve 50 degree centigrade , please place them at the air flow area .

*** DC blocker available for custom order ***
Because the serious disturb power line is rare, based on the customers feedbacked, it has around 10% users meet with serious disturb , so our power amps have not include the DC blocker . If customer has experience on vibration and noise in last power amp model, customer can custom order the DC blocker , it can kill 1.2V DC of the power line which is enough for most case.

Summary
Fully balanced design, the gain stages and pre-driver stages work in class A, built with discrete analog stages without any OPA or coupling caps in the signal channels.
The output transistor stages have supper excellent linear, it work with 100W pure class A station.
2 analog inputs: XLR / ACSS
Applies 80 pieces of ON Semiconductor transistors. Supports 100W X2 (8 Ohms) pure class A output, and 150W X2 (8 ohms) , 600 X2 (2 ohms) max output
The capacitance of the whole machine reaches as high as 260,000 uF, with two circle core and two R cores transformers (Total 1800W) and separate power supplies for the right channel and left channels.
A total of 4 groups of high-quality class A parallel connection PSU's supply the gain stages.
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.
