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.
Schuko plug
- 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.
③ LOUDSEPAKER TERMINALS
Connect the speaker to the terminals marked RIGHT "+ R"
and "R -" ensuring that "R +" is connected to the "+"
terminal of the enclosure and "R -" is connected to the
terminal "- "the same enclosure. Connect the LEFT speaker
to the terminals marked "L +" and "L -" by doing the same.
Make sure that no wires are not insulated can bypass the
speaker outputs. Make sure that the speaker terminals are
tight enough to ensure a good electrical connection. If the
terminal screws are not tight enough, the sound quality
may be affected.
Use only dedicated wire to the speaker (a section of 1.5
mm² or more is recommended especially if the cable length
is greater than 3m).
Important Note: Check the impedance of your speakers.
When using a pair of speakers, you can use speakers with
an impedance of between 4 and 8 ohms. BE SURE TO USE
THE MATCHING TERMINALS.
④ OPTIONAL BOARD
This slot allows you to add, when you want, one of the
Optional cards for adding one more source, like a digital
card that lets you listen to music from a computer.
⑤ PRE OUT (RCA OUTPUT)
This output allows you to use the amplifier as a preamplifier
and Therefore connect a power amplifier to upgrade the
system.
⑥ OPTION (INPUT) .
Several optional boards (Phono, Wifi, Bluetooth ...) will
allow you to add functionality to your amplifier. In case you
have not added option card, the OPTION entry will still
work as an AUX3 input.
⑦ LINE 4 & AV BYPASS .
This switch "by-pass" stages gain adjustment through use in
an Audio-Video system. In the context of the use of the
amplifier Bypass mode, please turn the switch on the rear
side above the entry LINE4/ByPass ON.
USE CAUTION WHEN AUX2 INPUT MODE BYPASS THE
MAXIMUM GAIN THEN. SURE DO NOT CONNECT A Y SORCE
WITHOUT RULE BEFORE ITS OUTPUT VOLUME TO A
MINIMUM.
⑧ LINE 2, 3 et 4 - INPUTS (RCA) .
LINE 2 to LINE 4 inputs are for connecting "line level"
sources to your amplifier. It is designed to receive an
"analog" signal (as opposed to "digital" signal). To connect
your source we are using a traditional "RCA" cable, they are
usually identified by a color code "RED" to the RIGHT and
"WHITE" to the LEFT channel.
Connecting a turntable: Most turntables have a "RCA"
output but the signal is not compatible with the "line
inputs" amplifiers.
.
To use a turntable, it is necessary to use a "phono preamp"
compatible with "cell phono reader" used. There are two
families of cells; MM (Moving Magnet) or MC (Moving Coil).
The majority of the public is using MM cells format.
⑨ LINE 1 - INPUT (XLR) .
XLR input allows the use of balanced connections. This type
of cables guarantee greater immunity to electromagnetic
interference. Their use is recommended in particular when
the distance between the devices is important.
