Model 394 is a full balanced amplifier from input to output.

You can enjoy natural and real sounds with it.
It is developed based on a special circuit, because we needed a headphone amp which can reproduce the musical sources without almost any noise in a process of development of condenser microphones.

It has a set of inputs that can be used either with XLR Balance Input or RCA Unbalance Input (Unbalance Input convert to Balance signal by inside amp.).

The power supply is AC 100V-240V, 50/60Hz for world wide use.

Model 394 can be of Abyss AB1266 also driven by the best sound quality.
