"The 6 major characteristics of electron tube amps pre amplifier:
Well, it is easy to replace the other devices.
1, collocation widely, strong practicability: collocation of all audio market signals: analog signal and digital signal input of the power amplifier and the active speaker.
2, the classic tube 6J1 design: the use of the classic tube 6J1 design, optimization of the circuit, the design of the electronic tube can be replaced, sound soft, mellow and sweet.
3, the power conversion module: the product uses the AC conversion DC power supply design, DC 12V power supply, the global general.
4, process excellence, highlight the style: the product uses all aluminum alloy shell, CNC numerical control technology.
5, using the boost mode, high voltage power supply: better than the common power supply mode, AC 100V-240V
6, mellow tone, sound mellow, sweet and warm, transparent Naiting.
A937 is a portable mini pre amps signal amplifier, a high performance sound processor, built-in high performance power processor and signal amplifier circuit design in the most classic
Electronic tube 6J1 to serve as the input and output signal processing amplifying function. For the high performance audio system design of a dedicated electronic tube, with ultra low harmonic distortion, low noise, high gain bandwidth, etc.
The dual channel FET input provides a wider dynamic range for the electronic tube, and the sound quality signal is amplified with bipolar circuits.
Signal loss and phase deviation of system caused by all kinds of reasons, so that the sound truly reproduce, make the listener feel high bass is rich, orientation, clarity, brightness
Close to the ideal field effect, in the sound system to add a signal to enhance the sound circuit will make the sound more beautiful, to give you more depth, slender and clear sense, high pitched,
A transparent mellow, full of natural strong bass, the listener has personally on the scene like effect. Pre amps signal amplifier, mainly used for signal input, such as computer, mobile phone, tablet computer
Brain, game machine, TV, TV box, MP3 any other signal source output devices such as signal input, input and output products using general RCA interface, audio signal amplification products using the switch.
In other areas where a signal input device can be used, which also can be used as a pre amplifier, power and signal power, the booster module isolated voltage divider,
High precision Taiwan production potentiometer for balance calibration, positive and negative voltage balance is very high. Otherwise the high capacity professional filter capacitor filter, the power is quite clean.
More clean.
Note: the product machine if there is a noise problem: there may be the following:
1, the electronic tube is not plugged in, carefully check the re insert tube, be sure to plug in the case of power outages.
2, the product is before the level with the signal amplification function, such as the noise source itself with the source itself be amplified with noise, so please play the use of audio signal is good.
3, the quality of the signal line is not good or the power supply filter is not caused by noise, can be replaced by the signal line or power to play "
