Page 8 INSTALLATION CONSIdERATIONS TURN-ON mOdES The SpeakerCraft 2-Channel Amplifier draws more current than a preamplifier’s switched AC outlet can safely supply. Also, your preamplifier may “thump” at dangerous volumes if the amplifier is already on when the preamp turns on. It is usually best to turn the amplifier on only when it is needed. The Turn-On Mode selector switch gives you three options for turning the amplifier on and off.

These speaker selectors provide an easy way to terminate all of the wires for more than three pairs. Testing and troubleshooting a new system is much easier with the individual room labels and on/off switches of a SpeakerCraft speaker selection system. Additionally, SpeakerCraft speaker selection systems offer impedance matching features which will allow you to connect up to ten pairs of speakers to your SpeakerCraft 2-Channel Amplifier.

The binding posts of the SpeakerCraft 2-Channel Amplifier will accommodate up to 12 gauge wire. Larger sizes can be accommodated by attaching banana plugs to the wire.

Page 16 CAuTIoN! Typically a preamp/receiver’s switched outlet is not rated for a power amplifier. The SC2-50, the SC2-100 and the SC2-150 draw 200 watts, 300 watts, and 400 watts maximum from an AC wall outlet respectively. Use a dedicated AC wall outlet along with the amplifier’s auto turn on circuit to ensure adequate power.
