Review: Nice Little Unit - I work in a truck shop and needed something with a small footprint that would set on my toolbox and be loud enough to be heard over all the noise. This meets all those criteria. Not sure where the volume complaints are coming from on here. At first, I had the same problem till I maxed out the volume with the remote and, my phone. Then voila this thing rocks and all volume is easily adjusted via the volume knob or remote. I personally don't use the remote due to the grubby hand's thing. I tested the remote and had no issues it's a little sluggish but functions all tasks. I have it connected to a set of old home bookshelf speakers and it rocks. My only complaint might be the tuning, as I have not been able to just hold the button down to advance up or down the dial rapidly it's kind of a tedious process to tune in but it has an awesome memory. It is not constantly powered on my box but when I return after the weekend it goes straight to the last channel. The reception for both Bluetooth and radio is very good. No annoying loud voice when connected either as I have seen mentioned on similar units. All in all, I would buy it again and recommend it. It also has a 12 power supply which I have not tried but may come in handy for the hobbyist out there I was considering connecting a 12v toolbox light to it. Connecting is straight forward and easy with my Android phone. And yes if you need the instructions good luck you'll need a magnifying glass or the Hubble telescope dang that's some tiny print. But they sent me an email link for a video which I did not need. I found the unit straight forward and easy to operate without instructions and I'm no spring chicken. So if ya got through my rambling then buy it already. Also, the extended warranty is cheap
Review: This device is fantastic. Solid BT connection thru garage wall rear of house 40' away - Great price and follow up from Sunbuck. They want you to be happy. Great sound, almost instantly connected to my iPhone. Took less than 2 mins for it to connect to Mac Pro Tower in the house ( SU 30 in the garage ). Decent sound. The treble and bass controls, actually work. Is connected to Polk monitor speakers. Great stereo separation. I contacted JS Electronics w question. Almost immediate response. Very very nice people. The 30 has much better BT range than the 60. The 60, better sound at lower volume, than w the 30. 180 vs 220 watts. Think, 38 watts RMS. In a room, both are clear and louder than most needs. From my garage, at 3/4 volume, door open, Can hear music across street in neighbor's back yard. These are both impressive work horses, with small foot print. Any issues, contact JS Electronics. They will make every effort to make things right.

## Questions & Answers

**Q: The power amplifier is connected correctly, why is there noise such as electric current?**
A: Please check whether there is current sound when no load. And confirm that the surrounding current signals will not cause interference. Please make sure all the cable completely pushed into the device, incompletely connections will create distorted.

**Q: Why only one channel work ? Is it defective?**
A: Since the amplifier is not used alone, it needs to be used together with other electronic equipment, so it needs to be ruled out one by one! Are the positive and negative wires connected to the speaker connected together?

**Q: If you find that the Bluetooth connection is unstable, you can try the following steps to solve it.**
A: Make sure there are no obstacles (especially metals) blocking the signal. Turn off the power amplifier, disconnect and clear the connection of the Bluetooth transmitting device, and try to reconnect.

**Q: Can you connect two devices with bluetooth?**
A: No, connecting two at the same time will cause the audio stream to be disrupted. It can only be disconnected and then connected to other devices.

**Q: How to connect to a bluetooth speaker?**
A: The Bluetooth speaker is a Bluetooth receiver, which is the same as the Bluetooth function of the power amplifier, and the Bluetooth speaker already has a small power amplifier, which may cause burn-in after being amplified by other power amplifiers.

### ⭐⭐⭐⭐ Some things to be aware of
*by S***N on August 16, 2021*

Purchased January 18th . It is now August 16th. 6 months of serious continuous use. Some bad things first Remote is pretty worthless. You need to laser line up the sensor perfectly. At dead levels ( in between songs during podcasts or low-level songs), the stereo clicks and makes crackling noises. I find this very annoying. You have to manually switch from media to the line connection by the knob on the unit. This switches the line connection from my TV to my 'media' Bluetooth or the radio. Not a real big deal but really? I play from a USB stick often but it does not show any file information just some buttons so you could advance the song or pause it. The volume played with the USB stick is 100% louder than anything Bluetooth so be aware. It plays instantly when you plug it in. It's good because you could use your Bluetooth for other things why you're listening to stereo music. Is there shuffle mode?? Confusing buttons, no instruction booklet, I tried going to their website where they say the instruction guide is but it was confusing I didn't have the time to deal with that BS The good points Overall the stereo sounds great. It pairs perfectly with my old thrift store 90s Panasonic system (built in 6" subs) speakers which I believe sounds comparable to what they make now a days. Soundbar and others. Just they're bigger which I like. the system has a lot of power and most times I only use it at half volume and it bumps hard! Don't even know if this has equalizers I think it does but I use the EQ on my phones player and i get the exact sound i want. I play all kinds of music. E d m, metal, shoegaze, hardcore punk , indie rock, Folk stuff, podcasts, lots of different YouTube videos, movies - through bluetooth and my tv, even the occasional CD also Games too, with my xbox patched in. The Bluetooth is noticeably louder then the TV connection but we just turn it up more. Note I think I left the stereo on too long and the Bluetooth connection was starting to go in and out this is the first time that's ever happened I thought it might have been my phone but I tried it on another speaker and there was no problem so I turned it off for about half an hour I'm playing it now and it sounds fine maybe it overheated? 6 months in. I really don't use the terrestrial radio since everything is online I have my digital radio stations so it's really kind of useless for me since I hate ads and DJs yapping away. And usually all my old programs stream now anyways. Overall I would say for my needs this was absolutely perfect. Great price, Great Sound is all I really want. Minus the radio and the worthless remote and the crackling noise. I had this hooked up in 10 minutes and was playing right away. Some hiccups, but yeah, recommended!
