Features

Unique and amazing combination: integrated T9 Pro amplifier with VU meter into whole in such a mini size when enjoy HiFi music the pointer dancing in the warm light with strong vintage feelings dynamically decorates the audio system space.

QCC3031 Bluetooth chip supporting ACC/SBC/APTX/APTX-HD 24bit/96KHz transmission can provide further distance and lossless signal makes the dynamic and details of music more excellent.

HiFi clear sound with tone control: resonable circuit and concise wiring adopts vacuum tubes to soften the sound and filter out the digital feelings sounds warm and sweet without noise. Also with treble and bass knobs to adjust one's own preferable sound styles presents HiFi music with rousing highs and deep lows.

Strong output power and low frequency output: each channel can output 100W(4Ω) match perfectly and easily to drive all 3-8Ω passive speakers adds a low frequency output easy to connect active speakers and build 2.1 channel system the bass effects is greatly enhanced.

With multiple digital audio inputs: Bluetooth 5.1 / USB / Coaxial / Optical / stereo RCA compatible with most audio device such as phones computers tablets TVs TV CD players etc. The perfect combination of DAC and amplifier very suitale for audiophiles who have various audio devices.

Practical funtions to simplify use: with input selection and indicators clearly to show the working status in real time; aluminum alloy case is specially designed cool and unique to decorate your desktop space.

Q: All my cables are connected but there is no sound output?

A: 1. Check whether the screen lights up. If the screen does not light up briefly press the

ON/OFF key to start the machine.

2.Check the screen volume value. If the volume value is too low turn the encoder knob or the remote control to the right to increase the volume.

3.If the above two points are normal check whether the playback device of the input sound source is paused muted or the volume is at the minimum.

Q: Why is the sound distorted?

A: The input level may be too large. If the volume of the sound source equipment is adjusted to the maximum and the volume of the machine is also adjusted to the maximum it is easy to be distorted. At this time turn down the volume of the sound source input device or machine.

Q: Why does the volume of the machine remain the same but the sound level is different when connecting to different audio sources (for example connect a CD first then a mobile phone)?

A: The amplitude of electrical signals output by different playback devices is different. For example mobile phones are usually 0.35V while CDs are 1V. The natural sound size is different.

Q: Why does the horn make a loud current sound?

A: If you use a power supply other than the original standard please replace the power supply before testing. Many power sources on the market have large interference coefficient of the text wave which will cause a large current sound.

Q: Why does the speaker make a loud buzzing sound when I plug in the input cable and do not connect the playback source?

A: When the unshielded signal line is unloaded the interference signal will enter the power amplifier for amplification. It is recommended to replace it with shielded signal wire or unplug the signal wire.
