Mi OPERATION
Note: Turn the amplifier on, and set it for listening to the sound.
(Refer to the operating instructions of the amplifier.)
Because as many as six types of equalization curves can be stored in the memory of this unit, tone quality adjustments according to each
tune can be made in fine detail and very easily.
1 Reduce the volume level of the
amplifier.
Set the amplifier’s tone controls to the center
(rston and set the super bass switch to
“QFF”.
2 Set the power switch to ‘“ON’’.

“MOST RECENT” memory
If, after the buttons and equalization levels of this unit have been
set, the power is switched to STANDBY and then switched ON,
the setting of each button and the equalization levels will be
entered into the memory, and these settings will return when the
power is switched ON.
Memory back-up
Lithium batteries are used to retain the data stored in the
memory, thus safeguarding the memory entries made by the
various buttons, as well as the equalization curves of the

stored
in
the
memory,
even
if
there is no power to this unit.
A word about the lithium batteries
This unit employs lithium batteries for back-up of the memory if a
power failure occurs, but these batteries will no longer provide
that back-up if they become weak.
If battery replacement is necessary, consult with the store where
the unit was purchased, or any store where Technics products
are sold, or an authorized Service Center (see enclosed list).

recorded with special equalization effects by using the
graphic equalizer.
First, display the curve
