- The new two models of amplifiers use the balanced circuit of model 404 which is one of the most popular models.
The input terminal uses Pentaconn manufactured by Nippon Dicks Co., Ltd. with high reliability.
The balanced output terminal is XLR in model 424, and Pentaconn in model 428.
The size of the body is smaller than 404, for the number of power-supplying batteries is down to 4 instead of 6.
No cable is used between the internal substrates, and all the connecters are gold-plated. The sound quality is clearly improved.
These 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.
