For safe operation and protection against fire hazard, replace fuse only with the same type
and rating as specified in the SPECIFICATIONS section.
Do not attempt to install or remove any vacuum tubes unless this unit is turned Off and
completely disconnected from the AC power outlet. Unit should be connected to the AC
outlet and turned On only after all vacuum tubes have been correctly installed or replaced.
Before attempting to replace vacuum tubes, always allow installed tubes to cool before
attempting to remove them. Hot tubes may cause burns or other injury if not allowed to cool
down completely to room temperature before removal.
Always unplug the Amplifier from the AC outlet completely and wait for at least one hour
before attempting to change tubes or open the cabinets for serving. Lethal voltages can
remain in the exposed tube sockets, electronic parts and PCB right after the Amplifier is
unplugged.
Contact your authorized SōLIS dealer or Spectra Customer Service hotline if you have any
questions about installing or replacing vacuum tubes or operating this system. Refer
servicing to your dealer or other qualified personnel.
AMPLIFIER LOCATION AND COOLING
The Amplifier is an open tube design and depends on natural convection airflow for proper
cooling. To ensure adequate cooling, the Amplifier should be located in a position such that
the airflow is not impeded or restricted.
The Amplifier should be placed on a level stable surface and should not be kept in an
enclosed shelf. It is strongly recommended to leave at least 6 inches of clearance above and
to both sides of it for best cooling.
CONNECTING THE SPEAKERS TO THE AMPLIFIER
1. Insert the banana plugs of the Speaker Cables (included) fully into the respective SPEAKER
OUTPUT TERMINALS located on the back of the Amplifier and Speaker boxes.
2. The banana plugs/terminals are color coded. The red color denotes the ( + ) end and the
black color denotes the ( - ) end. Make sure the correct colored plugs are inserted in the
same color terminals on the main unit and on the speakers.
Notes:
Make sure that the power is turned off when connecting or disconnecting the Speakers.
Make sure that the Speakers are connected to the correct terminals on the Amplifier,
otherwise the sound image will not appear midway between the left and right speakers but
diffused and coming from all directions. There will also be a considerable loss of bass
frequency response.
If you are connecting to a different speaker system other than the included one, be sure that
the speaker impedance of the new speaker system must be 4 – 8 ohms and have a power
rating up to 20W (rms) or higher.
The speakers are not magnetically shielded and may cause color distortion on the screen of
some older TVs or video monitors. To avoid this, you may need to move the Speaker boxes
further away from the TV or monitor if unnatural color shifts or image distortion occurs.
Contact your authorized SōLIS dealer or Spectra Customer Service hotline if you have any
questions about connecting your speaker system to this Amplifier.
CONNECTING THE AC POWER CORD
Unwrap and fully extend the AC Power Cord (included) and connect it to any convenient
household 120V~ 60Hz AC outlet.
Note:
The product is designed to operate on normal 120V~ 60Hz AC only. Connecting this system to
any other power supply could result in damage to the unit which is not covered by your warranty.
This system is equipped with a 3-prong AC power plug having a grounding connector. This is a
safety feature. If this plug does not fit into your existing AC outlet, you probably have an outdated
AC outlet. Do not try to defeat this safety feature by modifying the power plug to make it fit into
your outlet. Instead you should have your outlet changed by a qualified licensed electrician.
