9i-906 "Silver Fox" Headphone Amplifier
9i-906
The nickname of 9i-906 headphone amplifier is "silver fox". Purpose is to drive “monster” headphones. Its circuit architecture originates from a large power amplifier. When many redesigns for electrical characteristics and adjustments of sound style were completed, "silver fox" became a wonderful headphone Amp. High analytical, high density and neutral without tendency, especially power driving fprce, make it leader in similar products. . Whether high sensitivity or low ,high resistance or low , dynamic earphone or flat panel headset, "silver fox" can adapts to them by it's super driving ability and quality. It can show the characteristics of headphone more than normal headphone amp.
Introduction:
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 .
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.
