Enhance connection 1 to Bi-Amp connection, and drive the
bass speaker and Mid / High Frequency speakers with sepa-
rate 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 electromo-
tive force between the Low and Mid/High signal can be less-
ened. We can expect drastic improvement of 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 Un-
balanced only.

Wiring the speaker system
● Please remove short bar of the speaker terminal.
If the short bar, has not been removed, 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 capabili-
ties. If they don’t the protection circuit will be engaged and
there will be no output. Or it will damage the power ampli-
fier.
