BLUETOOTH

Your appliance allows the reception of audio signals sent from any device having a Bluetooth® transmitter (Smartphone, tablet, computer…).
First time association

• Activate the Bluetooth® connectivity of your emitter device.

•  Select the Bluetooth® (BT) input of PR400: unlock symbol BT

• Select your appliance on the list of the possible receivers (named IN200).

• Once the connection is made, the lock symbol BT appears.

The whole audio signals of your device source will then be transmitted towards your PR400. Your emitter device will remain associated until you unlock the PR400 with your Smartphone or switch off your amplifier.
Association of another emitter: Once associated with an emitter, you’ll need to switch completely your PR400 off in order to make it visible from another emitter. The quality of reception of the signal depends on the power of the Bluetooth emitter and the distance between the 2 devices. Avoid being more than 5 meters from your PR400 for a correct reception without any risks of signal cuts.

USING THE BYPASS INPUT

Warning: reduce the volume of the source connected to BYPASS before any use of the BYPASS Input. The BYPASS Input offers you the capacity to use your Integrated as a Power amplifier (plugged to an A/V processor for example). This Input can be selected from the front panel (knob 15) or with the BYPASS key of the remote control (hold 3 seconds). Once selected, “BYPASS” appears on the display. Then, no other functions are available from the front panel or the remote control. Turn knob 15 or hold the BYPASS button to get back from BYPASS.

USB INPUT

Your appliance is equipped with a High-Res. asynchronous USB Input (B type). It will be possible to use it only when you’ll have downloaded the appropriate driver on your computer. This driver can be freely downloaded on our website at the page:http://www.atoll-electronique.com/fr/produits/convertisseur-dac /convertisseur-dac200/

To avoid any troubles in the transfer of High Resolution files (24 bits/192kHz), it is recommended to use a USB interconnect with ferrite.
