0 This is an assembled board of 256 steps ( this is the newest incarnation ! The old one has 128 steps only)stereo volume control. This is done by a number of resistors and relays to complete the switch combination for minimal noise and distortion. Low noise, low tempco 1% resistors are used in the resistor network. Highly reliable Takamisawa relays are used. We do air shipping worldwide at US$10.00.
Board Dimension : 160mm x 134mm. Supply voltage : AC 220V - 240V.
Balanced in/out 256 steps volume control board passive pre-amplifier stereo !

Input Impedance : Between 1M to 10K, the frequently used volume levels between 20K to 50K
(Note : This is a R2R type attenuator. Therefore the input and output impedance varies with position)
Output Impedance : 4K to 1M, the frequently used volume levels between 4K to 30K
The board includes a sealed power transformer. The power transformer accepts 220V - 240V AC input ONLY.
The board can operate with AC plugged in. No schematic will be provided.
