Hooking Up the Components
Power Hookup
Before connecting the AC power cord of this preamplifier
to a wall outlet:
• Make sure that the power switch on the preamplifier is
in the off position.
Connect the supplied power cord to the AC IN terminal
on this unit.
Connecting to the power outlet
(European model only)
Connect the supplied power cord to a wall outlet.
3-pronged grounded outlet
(USA/Canadian model only)
The supplied power cord has a 3-pronged grounded plug.
If you are using a 3-pronged grounded outlet, the plug
can be inserted directly into the outlet. However, if the
socket is a 2-pronged grounded outlet, use the supplied
AC power plug adapter or a commercially available AC
power plug adapter.
If noise (hum) is produced
Noise may be caused by an electrical potential difference on the
ground circuit*. In this case, use the supplied AC power plug
adapter and be careful not to connect the ground lead to
anything.
* Although the ground of the domestic outlet is normally a safety
ground, a slight electrical potential difference may be
produced, depending on the outlet. Therefore, use of the
supplied 3-pronged power cord may lessen the quality of the
audio signal or may produce humming noise.
Note
We recommend that you connect this unit directly to a wall
outlet. If you must use a multi-outlet tap, or extension cord, be
sure to use one capable of handling high current (at least 10 A) or
one designed for office use.

• When using a grounded outlet (the inlets are different sizes)
Use the supplied AC power plug adapter.
