MODEL - ZEN TORII MK V - OWNER’S MANUAL DATE 11/2021
START UP
Before starting your amp for the first time, be sure all the tubes are installed in the
correct locations. Hook up your speakers to the amplifier. Do not hook anything to
the inputs of the amplifier at this time. With the volume controls all the way down,
power up one side of the amp first and then power up the other side. Listen for
noise and hum from each speaker. Whatever sound you hear should be about the
same on both channels. New tubes can make noise intermittently on start up while
the impurities burn off the plates. This is normal and should go away within the
first hour.
Now that the amplifier is on, and the gain control is all the way down, hook up your
source or preamp to the inputs. Start your recording and slowly raise the gain
control until you reach the desired volume.
PREAMPS
If you plan to use an active preamp with your TORII MK5, you may find the best
sound is with the gain control on the TORII somewhere below “all the way up” when
used with pre-amplifiers that have gain. Don’t be afraid to experiment.
As a general rule you can add weight to a recording by turning the preamp up
higher and the gain (volume control) on the amp lower. The reverse is also true if a
recording is too thick, just turn the gain on the amp higher and the volume on the
preamp lower. Of course this is system dependent as to how noticeable it is, but
many find it useful.
BREAK-IN
During the first few hours or days with your amplifier you will no doubt wonder
about break-in, if for no other reason than hearing about it constantly every time
you read about new amplifiers.
If you're new to tube gear the amp will sound
so good right out of the box
that you
will have a hard time worrying about break-in, so don't.
