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.
