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.
