Amplifier Requirements
With internal impedance matching (switch set to “IN”)
A 4-ohm stable amplifier is required.
With external impedance matching volume controls (switch set to “BYPASS”)
A 4 to 8-ohm stable amplifier may be used. 
(Note: overdriving your amplifier will potentially cause damage to the amplifier,
selector, and volume controls, as overload protection is bypassed.) 
Amplifier Connection
Note: use ONLY the amplifier’s A or Speaker 1 output. Do not use the B or
Speaker 2 output.
Using 4-conductor speaker wire (16-12 gauge), connect the A or Speaker 1 out-
put of an audio amplifier to the amplifier input connection on the SS-4.2/6.2.
Strip off 1/4” of insulation from the wire and tightly twist the copper conductor
to eliminate loose or frayed ends. Press down the spring terminal tab on the 
SS-4.2/6.2 and insert the wire, being careful to keep channel identity and polari-
ty consistent. 
Speaker Connection
With internal impedance matching
Using 4-conductor speaker wire (16-12 gauge), connect the first pair of speak-
ers to the Speaker 1 inputs on the SS-4.2/6.2. Strip off 1/4” of insulation from
the wire and tightly twist the copper conductor to eliminate loose or frayed
ends. Press down the spring terminal tab of the SS-4.2/6.2 speaker 1 output
and insert the wire. Connect the other end of the wire to each speaker, being
careful to keep channel identity and polarity consistent. 
Repeat the procedure for each pair of speakers that will be connected to the
SS-4.2/6.2.
With external impedance matching volume controls
Note: The recommended volume controls for the SS-4.2/6.2 are the Russound
series LPTx and ALTx. Consult the instruction manual of the impedance match-
ing volume control to determine the correct impedance matching settings to
employ for the specific amplifier and speakers.
Using 4-conductor speaker wire (16-12 gauge) connect one end of the wire to
the speaker output of the SS-4.2/6.2. Connect the other end of the wire to the
input connector of the impedance matching volume control. Using a section of
2-conductor (16-12 gauge) speaker wire, connect the wire from the output of
the volume control to each speaker.
