MASS-Kobo Model 465 Balance Headphone Amp

This model465 adopts the independent left and right power, twin balance monaural.

A clean, stress-free sound that does not feel the presence of the amp is a sound appropriate for a flagship model.

The output of this amplifier is balanced output 3.5 W + 3.5 W (32 Ω load).

Input is Balanced XLR 3 pin and Unbalanced RCA.

Reference input levels of Balanced are + 4 dBm / - 10 dBm selectable.

If you connect a device with an unbalanced output to a balanced input, the output will not be balanced.

Connect devices with unbalanced output to the RCA input terminals.
