Enhance connection 1 to Bi-Amp connection, and drive the bass speaker and Mid / High Frequency speakers with separate power Amplifiers. s 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-7S1 is mode), SC-7S1 and MA-9S1 can be wired by Unbalanced only. s Wiring the speaker system q Please remove short bar of the speaker terminal. If the short bar, has not been removed, it will damage the power amplifier. q Please use speaker systems whose impedance are for 4 16Ω. If impedance is lower than 4Ω, the protection circuit will be engaged during play. q 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. 4. Connections 7

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.
