9i-906 headphone amplifier, nicknamed "silver fox," is designed to drive monster class headphones. Its architecture comes from the power amplifier. It has made a lot of adaptive design for the electrical characteristics and sound style of headphones. The overall style is high analytical power, high density, neutral and non tendentious. For high-end audio equipment, neutral colorless and wide adaptability is the most important feature.
Whether it is high sensitivity and low resistance, high resistance and low sensitivity, moving coil or flat panel, "silver fox" has good adaptability, because it has enough driving force and outstanding quality, it can show the characteristics of earphone more completely. It is not only in the exhibition has been the tide of praise, but also has been highly praised by users..
9i-906 "silver fox" is a high-power and high-performance Headphone Power amplifier. It has a complex and perfect circuit design and power supply system. It has a high-power British field effect transistor as the output stage. It has an output capacity of 30 Ω / 20W. It can drive low sensitivity headphones and has excellent audio performance.
It has four output modes: normal, balanced, virtual ground and parallel, three low resistance modes and one high resistance mode, which can be used with various earphones.
It has two groups of balanced input and two groups of unbalanced input. Even if the input unbalanced signal is input, the internal circuit will turn it into balanced signal and then amplify it, so even if you input the unbalanced signal, you will get the maximum output power.
"Silver fox" has four kinds of output interfaces, such as four core balance, 6.35 single end, 4.4 balance and double three balance, which can meet the needs of a variety of headphones.
2： Operating instructions:
"Silver fox" is a pure earphone, the operation is very simple, only power switch power, input select input, output mode select out, high and low resistance select these function buttons.
Long press the out key to switch the high and low resistance modes. There are four kinds of earphone impedance selection: high resistance, low resistance 1, low resistance 2 and low resistance 3, which can be selected according to different earphones. High resistance is recommended in most cases.
3： Performance parameters:
Power: 20W (30 ohm BTL, distortion 0.02%)
Frequency response: 20-20KHz (0.2db)
