Common problems solution in ToneWinner audio products


Q1: The remote control fails, what should I do?


1. Check whether the infrared receiving window has any obstructions.

2. Check the battery of the remote control.


Q2: The power amplifier can be used normally, but the display does not light up, what is the problem?


1. The display screen is broken.

2. The +5V line plug of the power supply on the control board is loose.

3. The +5V voltage of the power supply on the control board is abnormal.


Q3: One channel of my amplifier has no sound, how can I solve it?


1. Swap the input signal L/R to see if there is any problem.

2. Switch to another set of input (eg: DVD to AUX) to see if there is a problem with the input.

3. Check whether the output terminal line is plugged in, or directly select A+B.

4. Check whether the selection of the audio source is consistent (the input on the back panel should correspond to the audio input on the panel).


Q4: The machine works normally, the display screen shows normal, there is input signal, but there is no sound from the speaker, what is going on?


1. Check whether the speaker wire is connected well, and reconnect (unplug).

2. Check whether the short-circuit connection bar between PRE and AMP IN on the backplane is well connected.

3. Check whether the sound source of the machine is consistent with the back panel.


Q5: When the power amplifier has no output, how can I solve it?


1. Please check whether the MUTE operation is performed on the unit.

2. Please check whether there is an audio signal input, whether the connection is correct, and confirm that the input group corresponds to the actual interface (the back panel should be consistent with the panel display).


Q6: My speakers sound very brittle, what should I do to avoid this?


1. Do not place the speakers in an inward orientation towards the listening position. The front of the speaker must be parallel to the rear wall.

2. Do not place the speaker too close to the side wall, the side wall has a reflective effect, and placing it too close will cause a strong reflection of the midrange and tweeter sound.

3. Do not use loud cables or electronic devices in the music system.


Q7: The bass of my speaker sounds humming, what is the problem?


1. The sound effect of the listening room has a significant impact on the music system, especially the placement of the speakers and the listening position. If the speakers are too close to a corner or back wall, the bass effect is usually accentuated. Moving speakers away from corners or back walls often results in more accurate bass. Bass can also be accentuated if your listening position is too close to the wall. Positioning speakers away from walls often reduces bass performance.


Q8: The bass of my speakers sounds weak, what is the problem?


1. Speaker placement

The acoustics of the listening room have a significant impact on the music system, especially the placement of the speakers and the listening position. If the speakers are placed far from the rear wall or corner of your listening room, place the speakers close to the rear wall or corner. This usually increases the bass effect. Bringing the listening position closer to the rear wall usually also increases the bass effect.

2. Input signal

The selection of the sound source also has a great influence on the bass output from the speaker. You can check whether the audio source such as the video source or CD disc is genuine and whether it contains bass. If the bass of the sound source is weak, the bass output from the speaker is also weak.


Q9: Requirements for speaker placement in the listening room


1. Please try not to place large objects near the speakers, otherwise unnecessary reflections will occur prematurely at the listening position. Speakers work best in rooms with common furniture such as bookshelves, flowers, vases, and soft furnishings. Moving furniture can have the same effect on sound as trying to place speakers in different positions.

2. If the sound is too loud, try to move the speaker or furniture. Carpets or mats can dampen unwanted reflections from hardwood floors.

3. The quality and size of the bass you hear depends on the size and shape of the room. Please try a different location. Placing it against the side or rear wall can enhance the bass effect, and placing it in a corner can also greatly improve the bass. Find the location that achieves the best sound balance for the room and your musical tastes.

4. After finding the best position, please place the speaker horizontally to avoid shaking back and forth. Spikes can be used to more effectively secure the speaker to the floor and keep the speaker level. We especially recommend the use of pegs on heavily carpeted floors. It improves bass response and enhances stereo sound.


Q10: What kind of connection is required between the player and the power amplifier?


The best way is to connect digitally.

* If you are transferring an HD format audio track

One is HDMI, which can transmit audio tracks in HD format losslessly and decode them through power amplifiers.

The second is to use optical fiber or coaxial connection, but the Blu-ray player can only transmit Dolby or DTS audio tracks in non-HD format with optical fiber or coaxial cable, or only 2-channel PCM signal can be transmitted after decoding it. (The Blu-ray player can output PCM, source code, XX, the source code is the best) This method can only be either your Blu-ray player is very high-end and the decoding ability is quite strong, or your power amplifier is relatively entry-level or old, and cannot be used. Decode HDMI, otherwise it is better to use HDMI to connect.


* If transferring db or DTS audio tracks in non-HD format

The first is HDMI, optical fiber or coaxial, even if it is a two-channel audio track, try to use digital transmission. Relatively speaking, the decoding ability of the power amplifier is stronger than that of the player, so that you can obtain better listening effects. The bridge power amplifier has the VLSC logo, which can eliminate the noise generated in the process of digital to analog conversion, making the music more pure.


Q11: My HIFI amplifier is very hot, is this normal?

Class A power amplifiers have a relatively large radiator, which is an inherent feature of Class A power amplifiers. The heat balance of a fever machine at about 50 degrees is a normal physical phenomenon and is not a malfunction. And our machine has overload protection, you can rest assured to use. Special reminder: In summer, due to the high ambient temperature, the calorific value will increase, so it is necessary to strengthen the heat dissipation. The power amplifier cannot be placed in a TV cabinet with poor ventilation, so as to prevent the heat from being dissipated smoothly and causing the power amplifier to burn!


Q12: My HIFI amplifier has decoding, can the XLR plug be used?

Your power amplifier is equipped with a DAC decoder, that is, you need to input digital signals from the audio source, and you do not need to input analog signals (you do not need to use the lotus terminal to input analog audio signals). The decoder has one optical input terminal and one coaxial input terminal, you can use optical fiber or digital coaxial input digital signal, the effect is very good. If you want to use the decoding input, you must use the optical fiber or coaxial cable to input the digital signal, and the input analog audio cannot make the decoding circuit work.
