“+” and “-” above the posts and “SPEAKER” in between the posts. For example, if you are connecting
the Stereo amplifier to the left channel speaker, you should take the speaker cable connected to the left
speaker and connect it to the amplifier’s “LEFT CHANNEL SPEAKER” binding posts. First, loosen
the binding posts on the amplifier. Take the red connector from the speaker cable and connect it to the
“SPEAKER” binding post marked “+”. Take the black connector from the speaker cable and connect it
to the “SPEAKER” binding post marked “-“. Tighten the binding posts by hand, using a nut-driver
(3/8”). Be careful not to over-tighten the posts, as you may break the connection inside the amplifier if
you exert too much force on the posts.
Voltage Setting
Your power amplifier voltage has been set by the factory, for the country where you made your purchase. The
voltage setting should be marked on the Serial Number Badge located on the back panel of your amplifier.
Check to make sure that this complies with your local voltage rating before plugging in and turning on your
amplifier.
Your amplifier is shipped with a power cord that matches the requirements of your country. If you need
a replacement and you are not sure what the appropriate cord should be, consult your authorized VTL
dealer or the VTL factory customer support department.
Power Source for your Amplifier
Your ST-150 Stereo power amplifier is a high-performance, high power amplifier capable of outputting up to
150 watts per channel. To assure that you can operate your power amplifier under the best conditions, for
optimal results, you should plug the unit directly into a wall AC outlet, preferably one separate outlet for each
unit. Do not plug your amplifier into a light extension cord or into the back of another component. This will
starve the amplifier of current and significantly impact the performance of your system.
