About Your Fusion 9 MK III
Black Ice Audio
’s Fusion 9 MK III Phonograph Stage Tube Pre-Amplifier is an example of state-of-the-art vacuum-
tube technology as it exists today. This product was designed to provide: 1) a Phono Stage that would deliver
musical accuracy 2) a significant value based on a high performance to price ratio and 3) a vacuum tube unit that
would exceed the reliability of solid-state units.
The Fusion 9 MK III is housed in a Heli-arc welded chassis and uses 2 pieces of 12AX7 tubes. Parts quality is the
best currently available, and the overall circuit layout is maximized for sonic purity.
Construction and Testing
Like every Black Ice Audio product, your Fusion 9 MK III has been carefully hand-crafted, using precision
mechanical parts. Electronic components and assembly procedures are similar to those used in the manufacture
of scientific equipment and musical instruments. To assure consistent performance, each Fusion 9 MK III is visually
inspected at several assembly points, tested, and electronically profiled prior to shipment.
This time-consuming perfectionist approach in the design and manufacture of audio equipment is intended to
provide the best in musical satisfaction with lasting value.
Handling Vacuum Tubes
Many may not have had experience handling vacuum tubes. However, most people have handled incandescent
light bulbs which are very similar to dealing with vacuum tubes. As with light bulbs, you should not touch a vacuum
tube when it is on since you can burn yourself. Similarly, if a tube is dropped on a hard surface the tube will break.
When you replace a tube, you should make certain the unit is disconnected from the AC outlet and that the tube
has cooled down. Never force a tube into a socket. You should treat the tube gently when holding or replacing it.
The precautions needed when handling a light bulb will give you a good guide on how to handle a vacuum tube.
Packaging
Save all the packaging in a dry place. Your Black Ice Audio phono pre-amplifier is a precision electronic instrument
and should be properly packaged any time shipment is made. It is highly probable that the unit will be damaged
during shipment if repackaged in a box and packing other than that designed for the unit.
You may have occasion to return the unit to the factory for service or shipment of the unit may be required for some
other situation. Should shipment prove necessary, the original packaging may save your investment from
unnecessary damage, delay and expense
