VX3    35W x 2 digital amplifier with built-in headphone amplifier and Bluetooth input
     
 
TPA3116D2 Amplifier
 
     
 

VX3 use TI’s TPA3116D2 amplifier, providing 35W x 2 output power and 0.0035% min THD+N.

 
     
 
CSR8645 Bluetooth
 
     
  VX3 use CSR8645 Bluetooth 4.0, support AAC, MP3 and APT-X.  
     
 
Bluetooth
 
     
 

You needn’t connect the audio cable while you using Bluetooth to enjoy music. You can even move your player(mobile phone or tablet) freely.

 
     
 
Full Aluminum Shell
 
     
 

VX3’s aluminum shell is made by automated machining center.

 
     
 
High-power laser engraving
 
     
 

Ink printed characters will fall off after long time use.

Common laser engraving is not deep enough, that makes the characters hard to read on silver panel.

VX3's characters was made by high power laser, it solve both problems above.

 
     
 
Mini Antenna
 
     
 

We specifically chose a mini antenna for VX3. No matter you place it horizontally or vertically, it can reach a distance of 10m.

 
     
 
Built-in Headphone Amplifier
 
     
 

VX3 has a built-in headphone amplifier.You can enjoy music by speaker or headphone.

When you plug in a headphone, speaker will be mute automaticlly until you pull out the headphone.

 
     
 
High-quality components
 
     
 

Better components will provide better sounding performance.

We use ALPS potentiometer, nichicon FW & ES capacitance, EPCOS capacitance, TOKO inductance and gold-plated PCB for VX3.
