SS-4.2 / SS-6.2
Instruction Manual
Impedance Matching
Speaker Selector
Introduction
Thank you for purchasing a quality Russound product. The Russound SS-4.2 and
SS-6.2 speaker selectors permit either four or six pair of speakers to be turned
on and off through individual switches on the front panel. Multiple pairs may be
engaged simultaneously if desired. When multiple pairs are engaged, impedance
matching protection must be employed to protect the amplifier from damage.
The SS-4.2 and SS-6.2 have this impedance matching protection built in, when
selected by the Impedance switch on the rear panel. They also have built-in cir-
cuit overload protection that disengages the amplifier signal if it exceeds the
limits of the selector. After being tripped, the amplifier must be shut off before
the SS-4.2 or SS-6.2 will automatically reset itself. If this occurs, check all sys-
tem components for proper connections and use.
Features
Designed for quality audio performance and long-term reliability
Impedance matching and automatic overload protection compatible with high-
powered amplifiers
Bypass mode for higher efficiency when using remote impedance-matching
volume controls
Isolated inputs provide safe connection to bridge or floating type amplifiers
Spring-loaded speaker terminals accommodate up to 12-gauge wire
Designed for use with 8 ohm speakers
Modes of Operation
The SS-4.2 and SS-6.2 may be used in one of two modes of impedance match-
ing: (Please note: impedance matching is required, but only once in the system.)
With internal impedance matching (Impedance switch set to “IN”)
This method of impedance matching uses the SS-4.2/6.2’s internal high-pow-
ered resistors to eliminate the need for external impedance matching devices.
With external impedance matching (Impedance switch set to “BYPASS”)
This method requires the use of external impedance matching devices such as
the Russound LPTx or ALTx volume controls, as the selector’s overload protec-
tion and impedance matching will be bypassed. In this mode, using external
impedance matching volume controls will allow higher system efficiency and a
configurable level of impedance matching for specific amplifier needs beyond
the scope of the selector alone.
Speaker Requirements
All speakers should be 8 ohms minimum.

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.
