Sonance SS4VC - Manual (Page 2)

INTRODUCTION
Thank you for purchasing the Sonance Speaker Selector System. You
have purchased one of the highest performance speaker switching
devices available, carefully designed to give you years of trouble-free
operation. Connection to your system is very simple. Please invest a
few minutes to read the complete instructions, before beginning your
wiring to assure the highest quality sound from your system.
UNPACKING
Save your carton and the styrofoam inserts for future safe transport
in case you move or the unit ever requires shipping for repair.
Before you proceed, find the serial number which is located on the
rear panel of the unit and note it here for future reference.

SS4VC/SS6VC BASIC CONCEPT
The SS4VC and SS6VC are designed to connect four and six pairs of
loudspeakers, respectively, to one receiver or amplifier. Each pair of
speakers can be independently turned on/off. The volume control
knobs give you independent volume control in all speaker locations.
These systems provide impedance protection whenever its
protection circuit is manually engaged by the user. When engaged,
the SS4VC and SS6VC adjust the impedance load presented to the
receiver or amplifier. With most amplifiers, when multiple speakers
are engaged, the protection switch should be engaged. With high
amplifier volume, your SS4VC and SS6VC switcher may become
warm. Do not operate your system below the impedance rating of
the receiver, amplifier, or the switcher. Check the owner’s manual of
your receiver or amplifier. Do not exceed the 75Watt RMS rating of
the SS4VC/SS6VC.
USING THE PROTECTION SWITCH
As a general rule, the more speaker pairs you have on, the more the
protection circuitry will be needed. Leaving the Protection switch
always engaged (“on” position) will provide the safest operating
condition for your receiver or amplifier. For most receivers or
amplifiers, the Protection switch should be engaged when more
than one Speaker button is engaged on the SS4VC and SS6VC
switchers. Failure to engage the Protection switch when multiple
pairs of speakers are engaged may cause damage to your receiver or
amplifier. The protection switch is located on the back of the SS4VC
and SS6VC switchers. Slide the red switch towards the left to engage
the 3
Ω protection resistors.Slide the red switch towards the right to
disengage the resistors and turn off the protection circuit.
NOTE: When protection circuitry is engaged, there may be a slight,
but perceivable loss of volume in the speakers that are engaged. This
is simply the trade-off for using resistive protection instead of
individual amp channels for each speaker pair or an impedance
matching device such as the Sonance AF8. Use dedicated amplifiers
if you require more dynamic range.
CUSTOM BUTTON LABELS
Sonance makes multi-room sound distribution even more user-
friendly by including Custom Button Labels (Sonance PN. 33-1468).
You can customize your SS4VC or SS6VC with a label for each button
that corresponds with the room or area in which you have a pair of
speakers playing. One sheet of button labels contains 120 pressure-
sensitive labels, each with a 3 to 7-letter abbreviation for nearly
every room or area likely to be encountered in your installation.
Each label fits the dimensions of the indentations under the buttons
on your SS4VC and SS6VC. A legend of the rooms or areas is
included in the package for easy reference. Consult your Authorized
Sonance Dealer for more information.
