Linear Tube Audio
Takoma Park, MD, USA
WARNING: For safety, the cover of this amplifier should be secured at all times.
DC
voltages as high as 450V and peak AC voltages as high as 800V are present inside. The service
information contained in this manual is intended only for trained service personnel. Furthermore,
this amplifier generates radio-frequency energy that can interfere with communications
equipment.
Quick Start Guide
-Remove the amp and power supply from the box and bags.
-Plug the AC cable into the power supply and into an outlet.
-The DC cable will have one end with a locking connector and one end with a plain connector. The
locking connector attaches to the back of the amp, where you should screw it securely but not as tight as
you can onto the threads of the DC jack.
-Insert the non-locking end of the DC cable into the DC jack on the power supply.
-Turn on the power supply using its toggle switch (if you are outside the US, make sure the voltage is set
correctly on the linear power supply, which is visible directly above the IEC connector).
-Turn on the amp with the power button on the faceplate. You may want to attach interconnects or
speakers before powering on, but it isn’t necessary. If you are using the MZ2/MZ2-S as a preamp, it is
best to have your power amp off (and
necessary to have it off if it is a DC-coupled amp
) when
powering on and connecting the MZ2/MZ2-S, to avoid off/on transients.
Please read this entire guide if
using a DC-coupled power amp.
