9i-906 "Silver Fox" Headphone Amplifier
9i-906 "silver fox" is a headphone power amplifier with high performance, strong power supply and high current output. It's circuit design is complex and perfect , 4 pairs of high-power British FET are used in output part , the output power is 30Ω/20W. Ultra low sensitivity headphones can also be driven with excellent audio performance.
It has four output modes: Normal, Balanced(BTL), Virtual Ground(Active G) and Parallel, as well as three low resistance modes and one high resistance mode. A variety of headphones can be matched .
It has two balanced and two unbalanced inputs . Even if you input an unbalanced signal, the internal circuit will convert it into balanced signal . Therefore, even if you input an unbalanced signal you will also get the maximum output power.
"Silver fox" has four output interfaces: 4 pin XLR balanced, 6.35 single , 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 , 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 for choice : high resistance, low resistance 1, 2 , 3. You can selected any mode according to whether you hear noise . High resistance mode is recommended in most cases.
