① GROUND ON / OFF
Make sure that the device is not plugged into the mains
before making any connections. It is also recommended to turn
off or disconnect all other devices associated while making
connections to the product.
Connect the speakers to the speaker terminals on the back and
the sources of the corresponding input jacks on the back.
IMPORTANT:
Make sure you have set the voltage selector ④
to suit your country: INPUT VOLTAGE:
AC110 (USA)
and
AC230
(EUROPE).
Connect the power cord to the connector on the one hand
AC Mains product and the other to a wall outlet. Turn the
POWER switch ⑪ (page 7) to the ON position (I).
If the unit is equipped with a standby, then press the STANDBY
button to turn it on.
Press the input selector for the source you want to hear.

WARNING:
Be sure to turn off the power on your product before
making any connections. Similarly it is best to cut the power of
other devices you want to connect to your amplifier.

SWITCH ANTI-HUM
Your EX-332.2 has a mains socket outlet
with a ground connection. The use of
this type of connection is recommended
for electrical safety reasons (including
wetlands). However sometimes this connection «mass» is the
origin of «hum» audible from the speakers in a hi-fi system to
solve this problem, the cancellation of the ground connection
is sometimes sufficient. To do this you have, under the device,
a switch to choose to connect or not the mass of the device to
the mains.
② TRIGGER OUTPUT
This 3.5 mm Jack mono output is used to activate or desactivate
remotely auxiliary devices connected to the amplifier. When
the unit is turned on, the output is switched to 12V. When the
unit is turned off, the trigger output is 0V.
③ PHASE TESTER
The EX Series products feature 3-pins mains power cord. These
3-pins plugs are respectively the Ground, which is located in the
center of the outlet, the Neutral, it is an electrical reference,
and finally the Hot. The latter is that which "handles" the
alternating voltage.
According to the wiring of the multi-socket and a sense of
connection to the outlet, the respective position of the Neutral
and Hot out will change, according to this position a residual
voltage may appear on the cabinet of the device. This tension
can affect the result of listening to your hi-fi system.
In order to choose the most appropriate direction connection
(one that will induce the lowest residual voltage on the
cabinet), some EX Series products have a Test device at the rear
panel of the product named: "Test Phase".
To test it is necessary to connect the device to the mains, and
then use your finger to touch the metal ring located around the
central lamp.
If the lamp lights it means that the residual voltage of the
cabinet is high. You will therefore then reverse the connection
of the outlet of the device (careful, the light intensity is low).
If the light remains off when you touch the ring around the
central lamp, it means that the device is connected in the best
way.
Notes:
- To choose the direction of the outlet connection it is necessary
to have a Schuko socket because the Ground is offset on the
sides.
- When the test is performed by touching the ring, make sure
not to touch any other part of the product which would have
the effect of putting to pair and thus invalidate the test.
