1 . Find out the minimum impedance of the amplifier. This
information may be found
in
the manual or on the back
of
amplifier, near the speaker terminals.
It
is
measured
in
ohms.

NOTE:
To
prevent from
overloading and damaging
the amplifier, the switch must
be set correctly to match the
impedance of the speaker
system to a
level
equal to or
greater than the impedance
of
the amplifier.
. . . . . . . .
2.
Figure out the total number of speaker pairs to be used.
3.
Determine the correct switch setting using the chart below.
4.
Set the switch. Make sure that each volume control's
switch setting
is
consistent throughout the whole system.

Installation Instructions
Route the cable into the volume control J-box
in
a way that allows for
easy access to the connectors on the SVC
Make sure to use the integral strain reliefs where appropriate when
routing the cable
in
the J-box.
Mark the input and output cables accordingly for easy installation.
Strip the insulation off the end of each of the eight individual wires
( four from the amplifier and four
to
the speakers) at about 1 /4". Twist
exposed ends together.
5.
Connect the leads from amplifier to the volume control connector
according to the labeled Input L [ + , - ] and R [ + , -
].
6. Connect the speakers wires to the connector labeled Output
L [ + , - ) and R [ + , -
).
Speaker wires typically use the
following color configuration.
- Red/Black = right speaker
Red
= positive [ + ] Black = ground [ - ]
- White/Green = left speaker White = positive [ + ]
Green
= ground [ - ]
7.
Insert the volume control into the J-box. Mount carefully, making sure
that no wires
are
pinched or shorted. Mount the cover baseplate to
the volume control then snap on the smooth facia cover.

Volume Controls
Picking the right Volume Control for your application: Two basic types:
Transformer Type with Impedance matching capability. This covers more than 90
percent of all installs utilizing a basic manual Volume control. It adds flexibility to your
system by allowing you to control the volume level in a dedicated room. It does not add
gain to the system but actually attenuates or decreases the sound (you around turning
the sound down). During setup you set the source volume to the optimum level then the
volume control turns the sound down to almost inaudible levels. Most impedance
matching volume controls do not turn the sound off completely unless they are equipped
with an off switch (found on our model SVC205).
The Impedance matching feature allows for maximum flexibility when designing a
system featuring multiple speakers direct from either an amplifier/receiver or from a
Speaker selector connected to an Amplifier/Receiver. In all cases it important to select
the best components for you particular application. OSD features multiple options in
Volume Controls, Amplifiers and even Speaker Selectors.
We also offer two styles, a rotating knob and slider style version. Both styles are
shipped with a white, ivory and almond matching color Decora insert, knob and outer
plate (Slider control shipped with Slider knobs)
We also offer a Impedance matching model that features a two way A/B switch for
either two speakers from a single source or a single speaker with dual source option.
