INSTALLATION CONSIDERATIONS

Speaker Compatibility

CAUTION! Do not use speakers with an impedance of less than 4 ohms with an unbridged channel. Do not use speakers with an impedance of less than 8 ohms with a bridged channel.

An unbridged channel of the SI-1230 is designed to play into a speaker load of four ohms or more. When a four ohm speaker is connected, the continuous power rating of the amplifier increases to 37 watts RMS per channel, (all chan- nels driven). If the load is less than four ohms the protection circuits may operate and shut off the channel at higher volume levels.

A bridged channel requires that the load be eight ohms or more to deliver 80 watts RMS. If the load is less than 8 ohms the protection circuits may operate and shut off the channel at higher volume levels.

When designing your system try to specify four to eight ohm speakers (Niles offers a complete line of architectural loudspeakers with several models rated at 8 ohms).
