Digital Audio Switcher 4/1
This product is a stereo digital audio channel switcher, featuring volume, treble,
and bass adjustment functions, an EQ sound effect function, a custom sound effect
function, as well as audio noise isolation effect and one-key switching function
via infrared remote control.
Function Description
1，Mute: Press the encoder twice consecutively to enter mute mode. To exit mute mode,
either rotate the encoder left or right, or press the encoder twice consecutively
again.
2，Volume: Rotate the encoder left or right. Rotating left decreases the volume, whil
e rotating right increases it.
3，Treble: Press the encoder briefly; the "H" LED will light up, indicating treble ad
justment mode. Rotate the encoder left or right to change the parameters. This als
o serves as a custom sound effect function. If the encoder is not operated within
5 seconds, it will automatically switch back to the volume adjustment function.
4，Bass: Press the encoder briefly; the "L" LED will light up, indicating bass adjust
ment mode. Rotate the encoder left or right to change the parameters. This also se

CH4 channels.
6，EQ Sound Effect: Press the EQ button on the remote control.
7，Power Supply: It operates on a 5V DC (direct current) power source and can work st
ably with a current of 100 milliamperes (mA) or less. Power can be supplied from d
evices with a USB port, such as the device's own USB port, a computer's USB port,
or a mobile phone charger.Operating voltage: DC5V 100 mAVolume control level: 63 levels / 1.25dB
Bass control level: 28 levels / 2dB (-14 to +14)
Treble control level: 28 levels / 2dB (-14 to +14)
Input gain: 3.75dB - 11.25dB
Maximum input signal: 1.2Vrms
Channel separation, f=1KHz
Total harmonic distortion (THD): 0.01-0.1%
