Updated the external DC power supply terminal of the full balanced headphone amplifier model 428, which has been popular since its release, from USB micro B to USB Type-C.
The input and output terminal of Balanced uses Pentaconn manufactured by Nippon Dicks Co., Ltd. with high reliability.
No cable is used between the internal substrates, and all the connecters are gold-plated. The sound quality is clearly improved.
This amplifiers are equipped with a mode change-over switch that enables you to connect both balanced and unbalanced output players.
Both models are equipped with the same output gain-changing switch as the one used in model 406, our flagship model. Now you can listen to all types of headphones and earphones, with both dynamic and balanced-armature drivers properly with a single amplifier.
It can be used for about 4 hours with alkaline AA batteries. (It varies depending on battery condition and type)
It can also be powered by connecting a power bank to the USB Type-C terminal. (There is no charge function, digital input / output function)
*Balanced output of model 475 is not compatible with unbalanced headphones and earphones. Unbalanced headphones or earphones connected to the balanced output with or without adapters may cause the amplifier to malfunction. NEVER connect them to the balanced output. Please use 3.5 mm unbalanced output for unbalanced headphone or earphones.
