Volume Controller/Balance Potentiometer/Balance

Advanced Relay Volume Controller/Balance Potentiometer/Balance to Unbalance/Passive(Balanced) Preamp RCA to XLR Knob(Selective)

Balance the 256 gear relay volume potentiometer. The resistance with the lowest basic resistance of the signal channel uses the imported SEI resistance with an error of one thousandth (one resistor alone is 2 yuan, and four for four channels). The other uses the 1% resistance of Philips, because usually the resistance with the lowest resistance is connected to the ground under the condition of low volume to high volume, and the volume control is completed by continuously connecting the resistors with different resistance values in parallel, The resistor with small resistance value and large resistance value is connected in parallel, which has the greatest or the smallest impact on the overall error. The error of this resistor determines the overall error of several groups of resistors (good steel is used on the blade). The output error will not exceed 0.3% when the volume is small to large, and the error in the last 1 / 5 section close to the maximum volume is 1% (you know that the error range of Alps 27 potentiometer is 5%).

This product adopts high-grade all-aluminum chassis, panel thickness 8MM, all-aluminum knob, high-grade atmosphere! Working principle: All music signal channels use imported resistors, and 16 (Takamizawa relays imported from Japan) switching resistors are controlled to complete 256-level step adjustment by adjusting the potentiometer (the potentiometer does not pass through the music signal, but only plays the role of control relays). No popping sound, no popping sound, pure resistance loop, higher fidelity than traditional carbon film potentiometers! The sound is more transparent! The effect is immediate! The machine is compact in size and does not take up too much space. It can be used for various pre-stages, volume control of power amplifiers, and all connectors are gold-plated with high gear. Even the inner 6-angle screw used to fix the socket is also a non-magnetic stainless steel screw. .

For the power switch part, it is not simple to use a switch and a transformer in series, because the power switch and volume control are integrated. Considering the possibility of damage to the power switch and leakage, the micro-current DC control relay is used to switch the machine on and off, and the transformer is used to increase the cost. The current does not go through the switch, which reduces the interference of the AC circuit to the sound, and at the same time is safer, and will not consume power when it is turned off.

The PCB is strictly in accordance with the safety requirements of the creepage distance. The PCB creepage distance of the strong current part and the weak current of the board is greater than 7.5MM.
