2.4.2 Unbalanced Connections
 
When using an unbalanced input source and connector, a jumper must 
be added between the negative (-) terminals and the ground terminals. 
Once this has been done, the unbalanced source can be connected to 
the positive (+) and ground terminals. Diagrams have been provided for 
standard RCA and TS connectors. Please refer to the manual of your 
input source in case it does not follow the standard pin-out. 
2.5 Output Connections
Stewart Audio recommends using high-quality, heavy-gauge speaker 
wire and connectors to send the output signal of your amplifier to the 
speakers. Use the following table as a guideline when selecting your 
wire gauge. 
 
 
 
 
 
 
 
 
 
Speaker leads connect by means of terminal block connectors supplied 
with the unit. Strip speaker leads 1/4” and insert into connector ob-
serving proper polarity. With a small, flat-blade screwdriver, tighten the 
screw until the leads are held securely in place. Inspect for possible 
shorts or broken wires.
