If it still doesn’t work, please delete the Bluetooth pairing name on the phone, make sure there are not too many Bluetooth names on the phone, and then search and pair again.
No sound from the speaker?
First, check that the unit is properly connected to the speakers. Make sure that the left/right channels are connected correctly, as incorrect connections may result in no sound output or damage to the speakers.
No sound from the 3.5mm headphone jack?
If the auxiliary jack is connected to wired headphones or powered speakers, the unit will automatically disconnect the speaker output. Unplugging the auxiliary cable automatically switches to speaker output.
Does the digital optical and coaxial support audio input and output?
The optical fiber and coaxial interfaces only support audio input.
What are the power adapter requirements? What should I keep in mind when plugging in?
When using a DC12-24V power adapter, turn the main power switch to the left position before applying power, then insert the DC plug into the DC hole on the back of the amplifier, and then insert the 12-24V power plug.

Great little amp.
This is a great little amp. The Bluetooth works great and it has impressive power for the price. I received it yesterday and had it setup in 5 min. ran speakers for 6 hours straight at 75% volume and the amp never got hot. Sound quality was great and the bass and treble adjustment were a nice touch.

System alerts are loud
Works great, only complaint is that every time it turns on or changes input it loudly says what its doing. Cant disable this or adjust volume. ‘BLUETOOTH MODE, CONNECTED’ ‘LINE IN’ tried muting when switching input, nope. Tried turning all knobs low as they would go. Nope. Great device wish i had volume control on the system alerts

Poor Quality
does not disconnect speakers when headphones are plugged in. Remote only turns unit on an off all other buttons do nothing. Voice announcing mode is way too loud. useless for my application.

High distortion on optical INPUT
The whole concept sounded perfect for my intended use but unfortunately there were some problems that made it completely unsatisfactory.1) The BT connected, and worked very well and sounded okay with my smart phone but when I switched the amp to the optical output from my high end CD player, the sound was very very distorted just like it is when a CD is played through a video disk player.2) The volume control works very strangely; when set to low levels it seems normal but there is a point at which the volume output jumps noticeably and the sound becomes distorted. I say “distorted” even though it is not of the typical clipping, harmonic or intermodulation type. Instead artifacts associated with digitizing become apparent and very objectionable.3) The LED lighting surrounding the volume knob can be very useful when setting the controls but also visually very annoying when not turned off once the controls are set.The amplifier appears well thought out and well made with quality components and if it weren’t for the distortion when using the optical input, it would be a very good amplifier.

Great little amp
Based on the latest Motorola chip this amp is amazing sound wise. The Bluetooth capability is a bonus. My daughter teams the amp up with a pair of Polk bookshelf speakers. The only annoying thing is the power block is the same size as the amp.
