Russound SS-4.2 オーナーマニュアル
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.
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.)
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.

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.
