BLUETOOTH®
FILTERS SETUP
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 DAC300 : unlock symbol BT appears.
• Select your appliance on the list of possible receiver (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
DAC300. Your emitter device will remain associated until you unlock the DAC300 with
your Smartphone or switch off your amplifier.
Association of another emitter:
• To connect another emitter, you’ll need to disconnect the first 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 of your DAC300 for a correct reception without any
risks of signal cuts.
While pressing knob (20) you can choose different kind of digital filters which you can
select by listening:
• Standard: fast roll-off, minimum phase filter.
• Fast lin: fast roll-off, linear phase filter.
• Slow min: soft roll-off, minimum phase filter.
• Slow lin: soft roll-off, linear phase filter.
• Apodizing: Fast roll-off by apodizing and linear phase filter
• Hybrid: fast roll-off and minimum phase filter

CAUTIONS
• Do not make any connections when your device is powered on.
• Put your device in a dry and well ventilated place, far from a source of heat.
• Do not put something on your converter.
• Do not make any plug-in when the converter is on.
• Avoid any short-cut.
• Respect polarity +& and switch left & right.
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.
• To avoid any parasite sounds coming from some softwares, we recommend
you to unplugged the USB dongle from your computer when not using it.
E.C. marking certified the conformity with low tension directive 73/23/CEE, directive
CEM 89/336/CEE and national transpositions.
E.C. MARKING

GUARANTEE
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:
You will find attached an explanatory guide on how to install
this driver.
This driver is not required for Macintosh computers.
To avoid any troubles in the transfer of High Resolution files
(DSD & 24 bits/192 kHz), it is recommended to use a USB
interconnect with ferrite.
USB INPUT (14)

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.
– PCM : 16-24 bits (44,1 kHz, 48 kHz, 88,2 kHz, 96 kHz, 176,4 kHz, 192 kHz,
352,8 kHz et 384 kHz).
This DAC can be used as:
• Single converter as a source linked to a linear or XLR input of an integrated or
preamp which will setup the volume control. In that case you’ll need to fix the output
level of the DAC300 and put it on BYPASS position.
• Both converter and preamp directly linked to a power amplifier : volume control is
then made by the DAC300. In this configuration, you need to place configuration as
BYPASS OFF.
Put the DAC300 on stand-by then press knob (20) about 3 seconds. Position ON/OFF
changes on every press of the knob.
• Display BYPASS means that the volume control is not activated.
• Display BYPASS OFF means that the volume control is activated.
BYPASS MODE
Note : BYPASS mode is recommended when you’re using an integrated. If you are using
the DAC300 as a preamp, check if the amplifier is able to support a maximum input level
of 5 Vrms.
