I will send bill by Paypal later.
Cancellation after you pay cannot be undertaken unless it is impossible to manufacture the product. Please be careful.

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.).

XLR Bal;anced input have reference level select switch.
You can choice +4dBm from professional player or -10dBm from consummer player.

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.
