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 DAC300: unlock symbol appears.
Select your appliance on the list of possible receiver (named DAC300).
Once the connection is made, the lock symbol 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.

FILTERS SETUP

While pressing knob (20) you can choose different kinds of digital filters which you can select during 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

BY-PASS MODE

This DAC can be used as:

Single converter as a source linked to a LINE 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 BY-PASS 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 BY-PASS 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 BY-PASS means that the volume control is not activated.
Display BY-PASS OFF means that the volume control is activated.

Note : BY-PASS 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.

USB INPUT (14)

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:
