Finished machine B version: 0.1% left and right channel balance
This product is advancedAll aluminum chassis, panel thickness 10MM,All aluminum knobs,Upscale atmosphere! Product features and working principles: the full use of music signal channelsResistance of the 718 military factory(for the OEM factory, six resistance) by adjusting the potentiometer (potentiometer without the music signal, only plays a role to control the relay control completed 256 step adjustment,No pop, pure resistance circuitIt has a higher fidelity than the traditional carbon film potentiometer. The sound is more permeable! See the shadow of the effect! The small size of the machine, not too large space, can do all kinds of pre - level, power amplifier volume control.
Product function:
Balance the input and balance the output.
Balance input, nonequilibrium output.
Balance input, nonequilibrium output.
Simple point of understanding: This is a 4-channel audio signal control potentiometer tuning, the current sound quality of the best volume control!
Size: wide 165MM depth 190MM high 75MM
Heavy contract: 1.8KG
Working principle: All the music signal channels use imported resistors. By adjusting the potentiometer (the potentiometer does not pass through the music signal, it only functions as a control relay), 16 are controlled to switch resistance to complete 256 step adjustments. No popping, no popping, pure resistance circuit, higher fidelity than traditional carbon film potentiometers! The sound is more transparent! The effect is immediate! The machine is small in size and does not take up too much space. It can be used for various front-ends. The volume control of the power amplifier. The connectors are all high-speed gold-plated. Even the inner 6-angle screw for fixing the socket is a non-magnetic stainless steel screw. .
The power switch part is also thoughtful. It is not simply to use a switch and a transformer in series, because the power switch and the 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 cost. For the machine, the current of the transformer is not switched, which reduces the interference of the AC circuit to the sound, and is also safer. It will not consume power when turned off.
The PCB strictly complies with the safety requirements for creepage distance, and the creepage distance of the strong current part of the board and the weak current PCB is greater than 7.5mm.
There are two voltages: 110V power supply and 220V power supply
Product Features:
Balanced input, balanced output.
Balanced input, unbalanced output.
Unbalanced input, unbalanced output.
This is a 4-connection potentiometer, pure resistance circuit, the best sound quality volume control method at present!
XLR interface definition: 1GND 2+ 3-
