Unboxing Sienwiny YS-T50L CS8673

[Freedom666]

Unboxing / unpacking Sienwiny YS-T50L mini Bluetooth amplifier with close up Fotos of the board.

 

[Freedom666]

It has, different than ZK MT502 a volume rotary knob which only gives impulses and amp is turned on by pushing volume knob

ZK MT502 showed via Bluetooth superb clean sound, dead quiet with 24volt Meanwell 5ampere SMPS.

Will see how this one works.

Tried to find TD5165A datatasheet but could not find it. Must be the Bluetooth chip.

The cooling for the chipstar cs8673 is managed with a heat conducting self adhesive pad.

I fixed it with glue and a piece of cardboard so that it does not fall off.

 

[Freedom666]

I see now the cooling metal is too big in height another would would do better

[Freedom666]

This one has USB input, too!

 

[Freedom666]

The lower plate is one millimeter too long so it must be assembled other way round

 

[Freedom666]

As the self adhesive pad is thick and soft it looks like that extra glueing of the aluminium should be skipped and the upper metal sheet can be fixed with four screws pressing/fixing the cooling aluminium simply by assembling.

 

[Freedom666]

Amps will be used for open air fun projects where weight and space plays a role in portable hifi

 

[Freedom666]

Bluetooth YS Audio appears and it seems cannot be connected without App.

This is a drawback for the use of these amps!

For this reason I cannot recommend it.

 

[Freedom666]

Now managed to connect it without app.

Sound is not only o. K.. It's good!

Now recommendable. It was a bargain for below 10€.
