CONNECTIONS
Enhance connection 1 to Bi-Amp connection, and drive the
bass speaker and Mid / High Frequency speakers with separate
power Amplifiers.
BI-AMP (CONNECTION)
The benefits of Bi-Wiring; drive the bass speaker and Mid /
High speakers with separate power Amplifiers. Bi-Amping will
lessen the burden of Power Amp impedance, so that back
electromotive force between the Low and Mid/High signal can
be lessened. We can expect drastic improvement of sound
quality.
Caution:
In the event of this connection (Control Amp SC-7S2 is
<Stereo>mode), SC-7S2 and MA-9S2 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 systems whose impedance are for 4 -
16 Ω .
If impedance is lower than 4 Ω , the protection circuit will be
engaged during play.
• Make sure your speakers are designed for Bi Amp
capabilities. If they don’t the protection circuit will be
engaged and there will be no output. Or it will damage the
power amplifier.
