ENGLISH
Enhance the connection 1 to Bi-Amp connection, and drive
Low Frequency speaker unit and Mid / High Frequency
speaker unit by respective power Amplifiers.
■ Bi-Amp (connection)
The wiring method enhanced from Bi-Wiring, drive Low
speaker unit and Mid / High speaker unit by respective power
Amplifiers. Bi-Amp will lessen the burden on Power Amp im-
pedance, so that back electromotive force between Low and
Mid/High signal can be lessen, we can expect drastic im-
provement on sound quality.
Caution :
In the event of this connection (Control Amp SC-7S1 is
<Stereo>mode), SC-7S1 and MA-9S1 can be wired by
Unbalanced only.
■ Wiring the speaker system
● Please remove short bar of speaker terminal.
If short bar has not been remove, it will damage the power
amplifier.
● Please use speaker system whose impedance is for 4 -
16
Ω.
If impedance is lower than 4 Ω, protection circuit will work
during play.
● Speaker system has to comply with Bi-Amp connection.
If it didn’t, protection circuit will work and no sound signal
will come out. Or it will even damage the power ampli-
fier.
