ADVISES

To optimize the performance of your device, you should switch it on at least half an hour before any listening, the time for the power stage to reach its ideal working temperature.
Your device will give you optimal listening quality after this time-lapse.
Between two uses, it is, therefore, preferable to let the device in the standby position so that it remains at its optimum temperature.
At night or when you leave your home, it is best to use the main switch to turn off the device.
To optimize the sound quality of your system, we recommend that you choose good-quality connection cords. Do not hesitate to ask your specialist dealer for advice.

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 appears.
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 BY-PASS INPUT

Warning: reduce the volume of the source connected to BY-PASS before any use of the BY-PASS Input. The BY-PASS Input offer 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 BY-PASS key of the remote control (hold 3 seconds). Once selected, “BY-PASS” appears on the display. Then, no other functions are available from the front panel or the remote control. Turn knob 15 or hold the BY-PASS button to get back from BY-PASS.

This driver can be freely downloaded on our website at the page: https://www.atoll-electronique.com/en/xmos-specific-driver-usb/

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