Cen.Grand 9i-906 "Silver Fox" Headphone Amplifier


1 Year Local Warranty.

 

The 9i-906 headphone amplifier is nicknamed the "Silver Fox". Its purpose is to drive "monster" headphones. The circuit structure is derived from high-performance power amplifiers. After many redesigns and adjustments, the "Silver Fox" has finally become an excellent headphone amplifier. It not only has the advantage of high analysis but also features high density and neutrality. The sound is musical. It has outstanding driving performance and can drive low-sensitivity headphones. It is one of the best in its class...

Whether high or low sensitivity, high or low impedance, moving coil headphones or flat panel headphones, the "Silver Fox" is able to match them all with its superb driving ability and quality. Compared to ordinary headphone amplifiers, the Silver Fox allows headphones to fully reveal their characteristics.

 

1: Introduction:

9i-906 "Silver Fox" is a headphone power amplifier with high performance, strong power supply and high current output. Its 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.

Since its launch, the Silver Fox has received widespread acclaim. Both in the United States and in Europe, numerous users have given it high marks. Some well-known HiFi websites have also made detailed reviews.

 

9i-906 "Silver Fox" 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.

 

Two balanced and two unbalanced inputs were installed on the unit back panel.  Even if an unbalanced signal is input the internal circuit will convert it into balanced signal. Therefore, you will also get the maximum output power even if you input an unbalanced signal.

For the best sound quality, a balanced input is highly recommended unless you only have an unbalanced signal.

"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, and 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 select any mode according to the characteristics of the headphones as well as the sound quality you hear. High resistance mode is recommended in most cases.

If you use ultra-high sensitivity headphones such as earbuds, you may hear a slight noise. Don't worry, Silver Fox has 3 low-gain modes for you to choose from. You can choose one of the low resistance 1-3 modes and the noise will be eliminated.
