CAuTION! 

The amplifier must be off whenever you make changes to the 

input connections.

CASCAdE AUdIO OUTpUTS

The “Cascade Audio Outputs” enable you to connect another amplifier to your 
preamplifier output. The connectors are gold-plated RCA phono jacks. Connect 
them to another amplifier’s inputs with a standard audio patch cable. The 
outputs are not buffered; if you wish to daisy-chain more than 5 SpeakerCraft 
amplifiers you will need a buffered distribution amplifier.

1.  label all of the interconnecting cables for the sources 

they connect to.

use audio patch cables with rca phono plugs

attached to the ends.

2.  connect the sources by inserting the rca plug into the 

amplifier’s jacks. noTe: if you are using two amplifier 

channels in “bridged” mode connect the input cable to 

the even numbered amplifier input jack.

connect outputs from your sources to inputs on the 

amplifier. never connect a source or preamplifier’s 

input (e.g., record inputs) to the inputs of your 

Sc12-30.

1.  Plug the female iec socket of the supplied ac power 

cord (the supplied power cord is designed for 120V ac 

wall outlets), or use an appropriate iec ac power cord 

to match the electrical wall outlet you are using (e.g. 

240V ac), into the iec receptacle on the rear of the 

amplifier.

if you use a grounded power strip, surge 

suppressor or extension cord, verify that proper 

ground is maintained.

CaUTIon!

 Do not plug the amplifier’s cord into a 

preamplifier’s convenience outlets.

The Sc12-30 draws a maximum of approximately 

890 watts from an ac wall outlet. This is much 

more than the typical accessory outlet on the back 

of a component will provide. use the

Sc12-30’s auto turn on circuitry to turn on the 

Sc12-30 whenever the preamp is on.
