Introduction
The MZ2 is a Class A tube amplifier utilizing ZOTL (Zero-hysteresis Output
Transformer-Less) technology. The MZ2 is an evolution of the original
microZOTL designed by David Berning in 1999. It is equally exceptional as
a headphone amplifier, preamplifier, and low-wattage integrated
amplifier.

This has a locking 2.5mm x 2.5mm barrel connector on both sides. Plug in completely and tighten the locking nut. If you have an LPS+, check that the red voltage label reflects approximately your area’s voltage (115/220).
- Page 6 Operation If you prefer, you can leave the power supply on indefinitely and only use the power button on the front panel. The front panel features a power button, input switch, volume knob, and headphone jack. There are 3 RCA pairs on the back for 3 inputs, selectable via toggle switch on the front panel.
- Page 7 Tube Heater Voltage Jumper Settings The MZ2 can use 6SN7 or 12SN7 tubes as its output tube. When switching from one to the other, be sure to set the jumpers on the boards to the correct position. A 6-volt tube like the 6SN7 will burn out quickly if being given 12 volts.
