Operations of the Amplifier
The Ai4 can be connected to 4 different sources/signal input but not a LP/Phono directly.
It is extremely important to pay a lot of attention to a correct connection of elements of your
system (+ & -, Left & Right).
The quality of sound reproduction depends on it.
We recommend using high quality connection cables.
Step 1: connecting the signal interconnect cables and speaker
cables.
Source/amplifier
All signal input terminals are for non-balanced standard RCA plugs.
Make sure to connect the correct left/right channel terminals when connecting, otherwise the
sound stage won’t be existing.
If the interconnect cable plugs are not clean or are severely oxidized, it will downgrade the
sound quality. We suggest to use quality/reliable interconnect cable and plug, and check/clean
them from time to time in order to ensure that your hifi system works in the best possible
conditions.
If the signal interconnect cable plug is pushed or pulled out while the unit is working, it could
damage the unit...
Any connection of a source with the amplifier must be conducted
with the unit off!
Connection of speaker cables
The amplifier has 2 pairs of high quality, gold plated terminal, specifically specified for
Vecteur, one for the left and one for the right channel.
The cables can be connected on the amplifier connectors with banana or fork connectors, or
directly by removing the isolating material on the end of the cable.
It is critical to respect the polarity of the terminals and make sure that you connect the « +” of
the speaker with the “+” of the amplifier (same with “-“).
Always avoid at any time to have 2 cables in contact as there would be a risk of short circuit
and of damage of the unit or of the speakers.
Speaker connection must be carried out with the amplifier off!
