The box - I had to tear to open - contains the audio box (a small flattened cube of side 5cm), its AC adapter, stereo cable with two RCA plugs one side and the other a 3.5mm stereo jack, a visual installation manual and a multilingual Warranty booklet.
At the rear of the housing are made of three types: a 3.5mm female, two female RCA and the plug for the AC adapter.
Depending on your type of amp you can use the cord to one side or the other. Personally I already had an RCA cable connected to the AUX input of my stereo amp.
At the first connection to the mains, a "blip" sound indicates that the sound is output on the channel and the case illuminates a blue light on the front that flashes to indicate that it is detectable by Bluetooth devices .
I threw on my Blackberry detection Z10 who identified as Logitech BT Adapter. The connection is performed without problem.
Sound (CD quality Flac) is the same quality as a CD played live connection, nothing to say. No interruptions despite the wifi router right next (I listened to the radio on the TuneIn app for over an hour, and wifi signals and BT does not parasitize at all).
Same with my Playbook. Note that Logitech adapter has two connection channels and can switch from one source to another without having to reconnect the devices.
With PC (CSL my dongle is controlled and managed by the Toshiba Bluetooth Stack software) detection is hassle-free, for against the adapter automatically reconnects after disconnection. Even by unchecking the "Automatic Login" option, it changes nothing. The only way to cut the connection is to completely disable the BT function of the PC ...
There I was able to test HQ audio file and the sound is also very good, although it seems to me that the highest quality is converted and compressed for transfer. The sound is slightly worse than direct connection since my Asus Xonar U7 audio card, but it's still very correct, DVD quality sound is not compressed.
My only regret is the lack of switch. Plugged into the strip of my chain, the adapter stays on even when I turn off the amp. I can turn it off by the main switch of the power strip or by unplugging it.
In conclusion, this is a product that I recommend to easily connect to his PC or smartphone stereo wirelessly. Bluetooth is very stable and the sound of hi-fi quality but not HQ.
The pros:
Ease of Installation
Bluetooth signal stability even in a charged environment
CD quality sound
The -:
Automatic reconnection (sometimes painful with a PC)
No switch
Compressed Audio HQ
