1 Pair Chip and Knob option : use one pair power chip per channel , and with volume knob,
1 Pair Chip NO Knob option : use one pair power chip per channel , but WITHOUT volume knob,
2 Pairs Chip Knob option : use two pairs power chip per channel , and with volume knob,
2 Pairs Chip NO Knob option : use two pairs power chip per channel , but WITHOUT volume knob,
The options are with Volume Knob, It can be use alone or also with a pre-amplifier
The options are Without Volume Knob, it's a pure post power amplifier, it is need and suitable for using with a pre-amplifier to control the sound volume,
The options are with two Pairs Chip, it's more powerful, lower internal resistance, better low-frequency control
With Volume Knob view:
Without Volume Knob version: front panel have not volume knob:
Dual Power chip version's PCB view(it has dual paired power transistor chip per channel ):
NO Dual Power chip versions use one paired power transistor chip per channel:
This amplifier is an imitation of NHB 108 hi-end expensive power amplifier, it uses a no negative feedback amplifier circuit, Completely eliminate the speaker back-EMF on the impact of the amplifier. Sound natural, comfortable, super control. The driving power is more than the big class A amp such as KSA50,
Quality of material selestion:
- High imitation aluminum chassis technology, the machine weighs 25kg, the look is extremely attractive. (Hifi Exquis)
- It has a two OFC 300w toroidal transformer, the supply power of left and right channels is independent, which ensures adequate separation and energy
- 4 wheat original SPRAGUE or BC 75V39000UF capacitor filter arrays, (Hifi Exquis)
- Japanese Omron speaker protection circuitry and high-power soft-start circuitry. Let the machine and speakers are working in a safe state. (Hifi Exquis)
- Input Impendance: 100K ohms
- Line Gain:+26dB (Hifi Exquis)
- THD+N:-100dB@no load ; -60dB @8ohm
- CrossTalk:- 125 dB (Hifi Exquis)
- SNR:115dB (Hifi Exquis)
- Frequency Respons: 10Hz ~ 20KHz
- Impedance: 2-8 ohms
- Max. RMS Power:140W @8ohms 200W @4ohms
- Input:RCA x2
- Output: Left and right speaker connection
- Size: 440x380x160mm (W*D*H) (Hifi Exquis)
- Gross Weight: 28 KG (Hifi Exquis)
- Coupling capacitor of this amplifier has been upgraded to the most expensive French SCR (small S) coupling capacitor, the detail,the sound field as well as the human voice have been improved a lot.
- The actuel driving force is much better than the class A power amplifier such as KSA5.
- NHB-108 minimalist broadband circuit to make a wonderful sound.
- Input and output without any negative feedback or compensation
Metal shock machine feet, effectively prevent resonance of the machine, which make the sound more pure.
A toroidal transformer cores without breaks OFC provide sufficient energy
Resistance is the highest grade of non-inductive UK WEL resistor (Hifi Exquis)
- Soft start power supply board dedicated to the use of high-power amplifier, it can simultaneously control two sets of output transformer connected, the maximum power is 1500W. TYCO SCHRACK using a 12V power relay, as well as NTC resistor (Hifi Exquis)
- Soft-start to reduce interference on the grid, to reduce the impact of power circuits and components.
Omron Relay allows the speaker to get the most comprehensive protection. (Hifi Exquis)
Original ON MJL4281 MJL4302 power transistors chips , the top of hi-fi power transistors chip, use aften on some hi-end amplifeir (Hifi Exquis)
