USING THE BY-PASS 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 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 the preamplifier
or with the BYPASS key of the remote control (hold 3 sec.). Once selected,
mention “BYPASS” appears on display. Then, no other functions are. Press once

192kHz), it is recommended to use a USB connection cable with ferrite.
ACCEPTED FORMATS
- Accepted format on optical and coaxial Inputs: 16-24 bits (32 kHz, 44,1 kHz, 48 kHz, 88,2 kHz, 96 kHz, 176,4 kHz and 192 kHz).
- Accepted format on USB Input:
- DSD: DSD64 & DSD128.

BLUETOOTH®
Your appliance allows the reception of audio signals sent since any device has
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 BT -
Select your appliance on the list of the possible receivers (named PR300).
Once the connection is made, the lock symbol BT 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.
