Marantz MA-9S1 manual Bi-Ampconnection, Connections, Wiring the speaker system

4. Connections

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 - 16Ω.

If impedance is lower than 4Ω, 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.
