Marantz MA-9S2 manual Bi-Ampconnection, Wiring The Speaker System, Connections, English

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 - 16Ω.

If impedance is lower than 4Ω, 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.
