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.

Q: Why can't I find the Bluetooth pairing name?

A: Since power consumption is considered in the design of this machine, Bluetooth does not work when other channels are used. You must switch to Bluetooth input mode to search for pairing.

Q: can I change the tube directly without turning off the power?

A: No, because the machine works under high voltage, the hot plug electronic tube may burn out
and damage the machine.

Q: Why does Bluetooth sound intermittent?

A: When using Bluetooth to test the distance, it is normal that the sound is not stuck or disconnected (without any obstacles) within 10 meters.(Note: The router will interfere with the Bluetooth signal. Don't get too close!)

All the glowing online reviews are right

What a superb amplifier this is. I pair it up with my 48 year old Wharfedale Linton 3XPs and they sound better than they ever did with the Rotel amp I bought to go with those speakers 48 years ago, itself a very decent amp for its time. But now I am hearing little nuances from those speakers across the frequency spectrum I never heard before.

As for the aesthetics, this is spot on for me, with, what to me, look like different retro nuances in the one device - the VU meter so 70s or 80s, the LED display and moving coloured lights being a solid nod to the integrated hifis of the 80s and 90s, and the two valves being goodness knows what, 50s and 60s maybe. But it is all tied together in a very coehesive attractive aesthetic. My wife's comment when she saw it? "Its so you!"

Anyway, for the particular use case it is designed for, the smaller room I use it in, I can recommend it without hesitation.

Simplemente Excelente!!!

Muy buen amplificador,logra mover muy bien mis Boston Acoustics A40 primera serie.Con su Dac interno y files Flac logra ampliar el escenario y el detalle de una manera brutal!
Unicos detalles son: sin musica luego luego se pone en standby con un click y es molesto y otro es del porqué no usaron el TPA 3255 que es más potente???Como que le falta el sprint final para estar al 100%!!!
Por el costo está muy bien así que merece el maximo de estrellas, 5 bien ganadas!

Just the best value ..

This is the 6th I have at the farm and my homes.. Simply great value and with the right speakers .. great ..

Fantastic compact amplifier

This is great for a small system I've set up, with my tablet playing through the Aiyima T9 Pro and then out to a pair of small bookshelf speakers. Internal DAC of this amplifier definitely an improvement over the tablets. For the price, after the first two weeks, there is nothing to complain about.

Nice small amp.

Using it in combination with some old b&w CM1 speakers. Good sound, good build en very well shipped.
