Preamplifier Outputs
There is a pair of RCA jacks on the back of the unit labeled “Preamp Out” which is designed to
provide the input for a power amplifier when using the MZ2 as a preamplifier.
CAUTION
: when connecting to a direct coupled solid state power amplifier, the turn on and
turn off transients might be dangerous to the speakers and possibly the amplifier.
It is necessary
that when using the MZ2 as a preamplifier with direct coupled solid state power amps, first
turn on the MZ2, then turn on the power amplifier, and when powering your system off,
first turn off the power amplifier, then turn off the MZ2
. This is not an issue when using
tube power amps.

Power Tube Heater Voltage Jumper Settings
MZ2 tube sockets labeled V2 and V3 can be used with either 6 volt 6SN7 tubes or 12 volt 12SN7
tubes. There are two voltages for each tube. One is the high voltage that carries the audio. The
other is the heater voltage. This makes the tube heat up and glow. There are two jumpers that are
