(²) Access to inputs OPT1 – OPT2 – COAX1 – COAX2 – USB – BT is only possible if your appliance is equipped with the digital board.
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 offers you the capacity to pass
threw your preamplifier so the signal goes directly to the power amplifier
with no attenuation. Use it to plug the output of an A/V processor. To avoid
any trouble you can select this mode only via the front panel of preamplifier
or with the BY-PASS key of the remote control (hold 3 sec.).
Once selected, mention “BY-PASS” appears on display. Then, no other functions
are.
Press once more BY-PASS to get back from BY-PASS mode.
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:
https://www.atoll-electronique.com/en/xmos-specific-driver-usb/
You will find attached an explanatory note on its installation.
This driver is not required for Macintosh computers.
In order to avoid problems with high quality format transfers (24 bits/192
kHz), it is recommended to use a USB connection cable with ferrite.
ACCEPTED FORMATS
- Accepted format on optical and coaxial Inputs: 16-24 bits (44,1 kHz, 48 kHz, 88,2 kHz, 96 kHz, 176,4 kHz and 192 kHz).
- Accepted format on USB Input:
– DSD: DSD64, DSD128 and DSD256.
– PCM: 16-32 bits (44,1 kHz, 48 kHz, 88,2 kHz, 96 kHz, 176,4 kHz, 192 kHz, 352,8 kHz, 384 kHz).
BLUETOOTH®
Your appliance allows the reception of audio signals sent since any devices
having a Bluetooth transmitter (Smartphone, tab, computer…).
First time association:
- Activate the Bluetooth connectivity of your emitter device.
- Select the Bluetooth (BT) input of PR300: unlock symbol appears.
- Select your appliance on the list of possible receiver (named PR300).
- Once the connection is made, the lock symbol appears.
The whole audio signals of your device source will then be transmitted towards
your PR300. Your emitter device will remain associated until you unlock the
PR300 with your Smartphone or switch off your amplifier.
Association of another emitter: Once associated to an emitter, you’ll need to
switch completely your PR300 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.
For better reception, avoid being more than 5 meters of your device for a
correct reception without any risks of signal cuts.
