9i-906 Headphone amplifier "silver fox"
Whether high sensitivity and low resistance or high resistance and low sensitivity, whether dynamic earphone or flat panel headset, "silver fox" can adapt to them by it's Super driving ability and outstanding quality.It can show the characteristics of headphones more than ordinary headphone Amp.
9i-906 "silver fox" is a high-power and high-performance Headphone Power amplifier. It has complex and perfect circuit design, power supply system and high current design. It's output part adopts high-power British FET so has output capacity of 30 Ω / 20W. It can drive headphones with low sensitivity and has excellent audio performance.
It has four output modes: normal, balanced, virtual ground and parallel, as well as three low resistance modes and one high resistance mode.it can be matched with a variety of headphones.
It has two balanced inputs and two unbalanced. Even if you input an unbalanced signal, the internal circuit will convert it into a balanced signal to amplify. Therefore, even if you input an unbalanced signal, you will get the maximum output power.
"Silver fox" has four output interfaces: 4 pin XLR balanced, 6.35 single ended, 4.4 balanced as well as double 3 pin XLR balanced .
2： Operating instructions:
"Silver fox" is a pure headphone Amp and the operation is very simple. There are only several function keys: power switch, input selection, output mode selection out, high/low resistance selection.
Long press the out key to switch between high and low resistance modes. There are four kinds of headphone impedance options: high resistance, low resistance 1, 2 , 3, you can selected according to wether there is noise. High resistance is recommended in most cases.
