FIIO Q3 Balanced DAC Headphone Amplifier THX AAA-28 AK4462 XMOS XUF208 32bit 768kHz DSD512

AKM AK4462 Chip

The digital/analog conversion stage is entrusted to a DAC AKM AK4462 chip, integrating the proprietary Velvet Sound technology. This chip supports high sample rates up to 32bit 768kHz PCM and up to native DSD512. You will be able to enjoy your high-resolution files and the finest details of your favorite songs.

Connectors & LED Indicator

The Q3 is equipped with a complete set of connectors, with the output of the 3.5mm asymmetrical jack and the 2.5mm / 4.4mm symmetrical jack. It will therefore allow you to connect all types of helmets.

The RGB LED indicator on the volume knob changes color to quickly identify the sample rate of the file being played back.

≤ 48kHz : Blue

48kHz : Yellow

DSD : Green

Output priority: Jack 4.4mm balanced = Jack 2.5mm balanced > Jack 3.5mm unbalanced. If the balanced 4.4mm jack and the unbalanced 2.5mm jack are connected simultaneously, no output will be available.

Versatility

The Q3 adapts to all situations and all types of listening. For example, the Bass Boost function can be turned on or off with a switch. For this feature, a hardware circuit increases the gain by 6dB in the low frequencies, without affecting the mid and high frequencies.

In addition, for more convenient use, a multi-function button allows you to quickly select a gain level or filter.

parfait!
reçu rapidement, merci encore a vous !
après avoir eu le Q1, je ne regrette pas le Q3,il apporte plus de détail définition, précision, c'est chirurgicale ! couplé a mon baladeur Fiio M7 le couple fait des merveilles !

Excellent rapport qualité prix
A la suite de l'achat d'un beau casque, je me suis laissé tenté par cet at ampli sac qui fait remarquablement bien le travail.
La construction est sérieuse, la molette de volume précise.
Je l'utilise avec un OnePlus 5t pour steamer Qobuz et ça fonctionne très bien. J'ai gagné en précision, rendu et puissance. J'ai cependant dû faire l'acquisition d'une application (UAPP) afin que soient reconnus les formats hi res.
Les câbles USB auraient gagné à être un peu plus long, mais rien de rédhibitoire.
Bref, bon rapport qualité/prix.
