Developed to drive even the most demanding headphones with up to 8 Watts of power

The amplifier is built on a solid metal chassis and finished with a natural high quality oiled wood. On the front panel present are headphone outputs: balanced in XLR format and unbalanced in 6.3mm format. Other selectors include: touch sensitive stand-by button, volume control knob, impedance selector and audio source selector.

The audio source selectors allows choices of one of the three options: unbalanced RCA source (IN1 or IN2) and balanced XLR (IN3, left and right channels).

The touch sensitive stand-by button has a LED indicator. For a full "power off" of the amplifier please use the physical switch on the rear panel of the amplifier, near the AC connector.

Envy can work as pre-amplifier with a high level of maximum output (up to 10V RMS). On the rear panel there is a pair of RCA pre-amplifier outputs as well as two XLR connectors for balanced pre-amplifier output. Output voltage level is regulated with the volume knob.
