3.5-inch Touchscreen + Remote Control Volume Control Board, 4-to-1 Signal Selection
The NJW1194 is a professional analog signal processing IC introduced by New Japan Radio Co., Ltd. This board provides bass/treble adjustment, 4-channel input selection, and left/right channel balance adjustment.

It uses a precision resistor ladder network, completely eliminating mechanical wear and delivering pure sound quality:
Eliminates left/right channel imbalance, noise, and contact aging caused by conventional carbon-film potentiometers.

Total harmonic distortion (THD) is only 0.0015%, and channel separation reaches -120 dB.
In actual listening, this translates to extremely precise instrument positioning, non-harsh highs, and clean, tight lows, without the muffled or veiled sound often associated with traditional potentiometers.

Based on various suggestions from users and from a practical application standpoint, this board implements all information display and operation entirely through the touchscreen and remote control, providing an all-in-one solution.

Power supply: AC dual 7V–dual 15V (3 wires: AC GND AC). Recommended transformer power: 20W minimum.
Touchscreen controls: channel selection, volume adjustment, balance adjustment, mute operation, and bass/treble adjustment.

Remote control operations: channel selection, volume adjustment, and tone adjustment.
Settings menu: the gain of the 4 channels can be individually set between 1x and 5x.
The power-on volume and the volume when switching channels can also be set.

Treble and bass can be independently set for each channel.
