SUBWOOFER-VOLUME knob is used to control the volume of the subwoofer. Right-handed volume increases, and left-handed volume decreases.
The SUBWOOFER-FREQ knob controls the cutoff frequency of the subwoofer. The right-hand frequency increases, and the left-hand frequency decreases. The frequency adjustment range is 20HZ-200HZ.
8. The sound is small, but when the sound becomes louder, the sound freezes?
If the input power is insufficient,
9. What factors are related to the sound quality?
The sound quality is not only related to the power amplifier module, but also related to the power supply, sound source, and the entire audio system.
It is recommended to use a power supply of 18V19V24V with a current above 5A. If you only have 9V12V or 1A 2A power supply, it can be used but the power is low. When the volume is selected close to the maximum, it may be distorted and affect the sound quality.
2. How to choose a speaker?
Regarding speaker types: commonly used speakers are generally 4-8 ohms, which can be used. The left and right channel speakers need to be connected to full-range speakers or mid- to high-frequency speakers, and the power is between 20W-100W. The subwoofer speaker cannot be connected to an ordinary speaker, and a speaker with a subwoofer speaker must be connected with a power between 20-100. The dive frequency of the subwoofer speaker must be at least 50 Hz.
If you are a 50W-100W speaker, don't worry about the problem of speaker burnout. You can choose a 12-24V power supply. The higher the selected voltage, the greater the sound or power that can be output. The speaker power should not exceed 100W, otherwise it will affect the sound quality.
3. Introduction to audio input mode
This audio power amplifier module has two audio input methods: one is Bluetooth input, the other is AUX input, Bluetooth mode is preferred. Bluetooth can be connected in any mode. As long as the Bluetooth connection is successful, it is in Bluetooth mode, and the Bluetooth mode supports automatic connection back. When Bluetooth is not connected, AUX plug-in is in AUX mode. It should be note that when using AUX mode, you need to confirm that the Bluetooth connection of this module has been disconnected.
4. How to adjust the main volume?
The MAIN-VOLUME knob adjusts the main volume. Right-handed main volume increases, left-handed main volume decreases. The main volume affects the volume of the left and right channels and the subwoofer.
5. How to adjust the left and right channel high and low sounds
6. How to adjust the subwoofer?
SUBWOOFER-VOLUME knob is used to control the volume of the subwoofer. Right-handed volume increases, and left-handed volume decreases.
The SUBWOOFER-FREQ knob controls the cutoff frequency of the subwoofer. The right-hand frequency increases, and the left-hand frequency decreases. The frequency adjustment range is 20HZ-200HZ.
7. The voice is small and okay. When the voice becomes louder, the voice becomes muddy?
The sound is distorted, please turn down the total volume or change to a higher voltage adapter power supply.
8. The sound is small, but when the sound becomes louder, the sound freezes?
If the input power is insufficient.
9. What factors are related to the sound quality?
The sound quality is not only related to the power amplifier module, but also related to the power supply, sound source, and the entire audio system.

Hello Sir, Greetings! I recently purchased "Xinyi XY-T100L 100Wx2" amplifier after watching your previous video. I am driving Sony's 4Ohm 100w x 2 speakers "SS-GNZ88D" Now I am interested in building LM3886 Class AB Amplifier. My question is - Will it be worth to go for High Fidelity LM3886 Class AB Amplifier? or "Xinyi XY-T100L" Class D is enough for day-to-day use. Thanks!

[@WhatIThink]

3886 ic is not available in market nor it will be for at least one year. Therefore stick to class D only as of now. Otherwise you can give 7294 a try. It is better in all aspects.

[@sohombairagi4079]

Hello Sir, I have this same board and using it for quite some time. One issue I found is that when using AUX input, the left and right channel seems to merge. But on bluetooth the left and right channels are seperate. Can you check this in your board? Thanks and keep up the good work.

@What I Think Sir Mid-range speaker or woofer both are same or different?? Help sir I'm confused.. waiting for your response!

[@Thirteen..]

Subwoofer: largest-for very low frequencies Woofer: large-for low frequencies Mid-range: mid-sized-for mid-range frequencies Tweeter: small-for high frequencies Super-tweeter: smallest-for very high frequencies

[@Thirteen..]

Woofer: 5″ - 12″ diameter 20 Hz - 2 kHz Mid-range: 2″ - 8″ diameter 150 Hz - 5 kHz

[@Thirteen..]

For an instant difference we may call woofers to those that come with rubber surrounding cones and midrange speakers without it, mostly with paper cone. Midrange speaker drivers mainly cover vocals, flute, piano etc.

[@Thirteen..]

Better to read Google Forums for your questions rather be asking from so called KZbinr Philosophers.

Please do not name it Review & Sound Test, write it Demo and sound test. A Review must have based on pros & Cons with experiance of use for enough time. There are many complains about INK 201 of burnning the IC, Tracks and sound quality. May be some of them occur due to user mistakes but your reviews should also addreddes those possibilities. Handling a Class D Amplifire is very typical thats why wuzhiaudio built it as a complete package even included cabinet too. So only power supply and Speaker Drivers are left to connect. Indeed INK OCEAN don a great job with its class D amp boards but still there are many possibility to improve the product. The price range is not such that one could think to invest to burn. When an hobbyest stand to build DIY, would like to have products which can tolrate some misshandling too and Class D Amp is not of that catagory. Thanks & Regards your Fan
