The Back Story:Suffice to say that Jim Fosgate (nicknamed “Foz”) is a World-Class Engineer and is the
vision and expertise behind the F360. His repertoire of achievement spans every category of audio electronic
devices from two channel audio, car audio, surround sound, headphone amplifiers to digital audio equipment. If
one wants to experience a “live experience of audio”, Foz’s sound room epitomizes the fusion of his designs in
preamplifiers, amplifiers, source devices, cables and speakers. His proficiency is not a matter of a blind squirrel
finding an acorn. It is based on decades of document research and experimentation of every possible major
circuit approach, followed up by Foz building and auditioning the circuits himself. Many people have asked us
about the model number F360 which by most lights is rather like a fighter jet designation. The F in the model
number represents an abbreviation of Foz, and the 360 represent the objective of providing a significant three-
dimensional image.
Another aspect of Foz’s expertise is manufacturing acumen. His designs reflect that somebody has to make the
stuff and complications are not the friend of manufacturers. Foz’s circuits are second to none in terms of sound
reproduction, but when the added dimension of creating a unit that uses accessible parts, ease of assembly and
cost effectiveness, World-Class Engineer is not a complement, it is an identification of fact.
About Your F360
Black Ice Audio’s F360 Vacuum Tube Preamplifier is an example of state-of-the-art vacuum-tube technology as
it exists today. This product was designed to provide: 1) a Preamplifier that would deliver musical accuracy 2) a
significant value based on a high performance to price ratio 3) Features that will be useful to a wide range of
amplifiers in contouring the musical presentation 4) a vacuum tube unit that would exceed the reliability of solid-
state units. The F360 is housed in a Heli-arc welded chassis and uses 1 6SN7 vacuum tube. Parts quality is the
best currently available, and the overall circuit layout is maximized for sonic purity.
Many listeners in general want speakers to disappear, tight clear bass, extended highs without glare and a rich,
full midrange. Putting together a system that meets the expectation of the owner can be a hit and miss
proposition given the significant number of permutations of sound resulting from different combinations of audio
components. With the F360, Black Ice Audio has built a preamplifier with features that will assist in the
contouring of your sound preferences. The SSX feature (Sound Stage Expander) is a dimensionality circuit that
adds a greater sense of depth, space. It is a Jim Fosgate US patent (number 5,307,415) originally used in
surround processors. It was called a “panorama control”. It cross feeds signals between the channels so each
channel has a signal from the other which is out of phase. Negative feedback is applied around this stage in a
single loop. Output offset is controlled with DC servos allowing the buffers to directly drive the signal path with
no output capacitors. Separate, oversized storage capacitors are utilized on each channel to provide a rock-
solid supply voltage without voltage regulators to affect the signal. The circuit is configured so that audio signals
from the one channel cannot couple to the other, preserving soundstage width and depth.
The bass equalizer circuit is designed to increase up to 15 dB low bass impact without bass boom. Conversely,
in the event of boomy bass, the bass equalizer can reduce the boom up to 15 dB. In addition, there is a high
frequency equalizer circuit that can increase or decrease high frequency up to 11 dB. (Based on Fosgate US
patent 3,883,832). Distortion and noise are below the threshold of hearing. The bandwidth is very wide allowing
audio signals to pass through without colorations. Bandwidth is an amazing “ten times” threshold of human
hearing 2 Hz to 200KHz at -3Db.
Black Ice Audio considers the F360 to be a stereo preamplifier, however, we added one item, the ability to play
rear speakers for image reinforcement. Rear speakers add to the dimensionality of the sound if that is desired.
Construction and Testing
Like every Black Ice product, your F360 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 F360 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 is 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 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 preamplifier 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
Accessories
1 AC Power Cord 1 Cloth cover
1 Gloves 1 Cleaning Chamois
1 piece Tung Sol 6SN7 vacuum tube 1 Allen wrench
Preparation for Use
1. Place, do not toss your preamplifier on a flat surface.
2. Your F360 preamplifier is shipped with the vacuum tube installed. Should you need to remove the tube, you
will have to open the top, which is held to the chassis with two screws per side (use the allen wrench provided)
and five screws on the back. Inside you will see the tube. Gently lift out the tube. When putting the tube back in,
line the pins of the tubes with the socket holes making sure that the double space of the socket matches the
tube pins. When the pins are lined up, gently push the tube in.
Note: Contact Enhancers are not recommended for use on vacuum tube contact pins. With continual exposure
to heat and air, these substances can form gummy, dust-collecting residues which actually reduce contact and
degrade sonic performance. Proper external use of contact enhancers -- on interconnect plugs, speaker
connections, etc. -- is subject to the discretion of the owner.
Operating and Adjustment Procedure
1. Make sure you have read and complied with the CONTROL AND CONNECTION instructions prior to
attempting to operate your unit.
2. Make sure your Fusion F360 is properly connected to a high-current power receptacle via the attached power
cord (see Connections).
3. Attach the audio sources and power amplifiers to the F360.
4. Before you turn the preamplifier on, make sure connections are properly hooked up. Never run the
preamplifier without the amplifier and subsequently the speakers hooked up since this may damage the
transformer. When turning the unit on, make sure the volume control is at its lowest point.
5. It is best to turn the preamplifier on prior to turning the amplifier on. This will eliminate any warmup thumps.
6. Your F360 will now operate satisfactorily. However, a full stabilization or warm-up period of at least 5 minutes
is recommended before playing music and 45 minutes for best sonic performance.

Controls and Their Functions
Front Panel
1: POWER switch/INDICATOR light:
First, turn the rocker panel on/off switch that is at the back of the preamplifier on. The LED Black Ice Logo will
display an amber glow indicating that the unit is in standby. Press amber Logo or the standby button on the
remote to turn the power on. The indicator light will at first blink and the light will come on after a short period of
time signifying that the unit is on and ready to adjust and play. Press the amber logo or the standby button on
the remote to turn the unit to the standby position. To turn the unit completely off, turn the rocker panel switch
on the back of the unit off.
It is normal for a vacuum tube preamplifier to run "warm" if used for prolonged periods. All internal components
are operating at safe, conservative level and will not be damaged. Do not touch the tubes during operation or
for ten minutes after the unit is turned off, otherwise touching may result in a burn. Keep children and cats away
from the unit.
Note: Black Ice Audio does not recommend leaving your F360 on 24 hours a day as is the custom of some
audiophiles to achieve maximum sonic performance on demand. While this is often recommended for solid-state
equipment, Black Ice Audio does not recommend this procedure for vacuum tube preamplifiers. Since the tubes
in your amplifier are rated for 8000 hours of life, you may have to replace the tubes more often if you leave the
preamplifier on 24 hours a day.
2: Logic Display:
The purpose of the logic display is to give a visual perspective of the phasing in your system and works in
relation to the settings on the control of the Dimension Pro Circuit. To activate the logic display, push the toggle
switch to on. Standing in front of the unit, we will assume that the lights, going clockwise from the top are in a
north, east, south and west perspective. The east and west lights represent the right and left speaker
respectively. When the dimension control is in the narrow mode, the north light represents the in-phase mode.
When the dimension control is in the wide mode, the south light represents the out of phase mode. Please note
that even when the dimension control is in the wide mode, the north light will still be activated since there will still
be sound that is in phase or focused. However, the intensity of the north light will be diminished. In turn, this will
be similar when the dimension control is in the focused position, the south light will still flicker since there will be
sound that is out of phase in the recording.

8
3: DIMENSION PRO (SSX) control:
In the 12:00 position, the Dimension effect is in the null position or where the effect is neutral. This is the control
for the Dimension Pro circuit. Turning the Dimension control clockwise from the null position will increase the
panorama effect or give a wider dispersion of the images on the soundstage. Turning the Dimension control
from the null position counterclockwise will reduce the panorama effect or focus the soundstage between the
speakers. Set the dimension control to the position you prefer. In our experimentations, we enjoy the Dimension
control at 3 or 4 o’clock with vocal music since voices will be focused yet the sound will be wide. For
instrumentals, the Dimension control fully open has its charm. In the end, set it where you enjoy it, nobody is
wrong based on that guideline.
4: 360 SPACE MATRIX (REAR SPEAKER) volume control:
Setting up the volume level for the rear speakers is similar to setting up a powered subwoofer. Turning the
control knob clockwise increases the sound level and turning it counterclockwise decreases the sound level.
With music playing on the front speakers, adjust the back channel volume control to a level in which the sound
between the front and rear speakers are in balance. We often set the volume on the rear speakers at a volume
level lower than the front speakers so that the rear speakers act as a sound reinforcement for the front
speakers. Once the volume level is set, as with a subwoofer, the main volume control becomes the master
control increasing or decreasing the front and rear speakers in tandem.
5: MASTER GAIN control:
This control is used to adjust the output volume level. Turning the control knob clockwise increases the sound
level and turning it counterclockwise decreases the sound level. This increase in volume and decrease in
volume can also be accomplished with the remote control. The joys of modern technology.
6: ON/OFF switch for the Equalization circuit:
If you wish to use the equalization circuit, turn the EQ toggle switch on. Please note that the equalization circuit
does not increase the volume of frequencies that are within the range of human hearing. Rather it controls
subsonic frequencies that will enhance the high and low frequencies of your music system.
7: Hi Frequency and Low Frequency Equalization controls:
Used to increase or decrease the high frequency (treble) or low frequency (bass) performance. Turning the
control knobs clockwise increases the high or low frequency up to 9dB while turning the control knobs
counterclockwise decreases the high or low frequency level up to 9dB. In the 12:00 position, the EQ is in the
null position or a neutral position. The EQ feature can be useful in compensating for variations of the
components in your music system and the variances found in different sources or recordings.
8: SELECTOR switch:
Used to select the audio source to be heard. There are five selection positions that can be chosen by turning
the knob clockwise or counterclockwise.
9: ON/OFF RECORDING loop switch:
To activate the recording loop, turn the toggle switch on. Music can still be heard when recording. The volume
level of the preamplifier does not affect the output of the recording signal.

9
CONNECTIONS
Rear Panel
1: RECORDING connections:
Use RCA jacks to attach your recording unit to the F360. The output from your recording device should be
attached to the REC IN RCA Jacks paying attention to the Right and Left inputs. The input of your recording
device should be connected to the REC OUT of the F360.
2 and 3: AUDIO signal connection input jacks:
One set of XLR Jacks and five sets of RCA jacks. Please note: Setting 1 of the selector knob is shared by the
XLR inputs and the RCA input jack 1. If you are going to use the XLR inputs, you would then use RCA inputs 2
thru 5 leaving RCA input jacks 1 empty. Use XLR or RCA jacks to connect the audio signal cables from your
source components to the preamplifier. The audio signal cords should be connected to the proper input output
jacks for each unit. Note: The jacks are numbered and correspond to the 1 thru 5 on the front panel selector
switch. Be sure to observe the proper polarity, i.e., the right channels of the preamplifier are connected to the
corresponding right channels of the component, etc.
4, 5: OUTPUT TERMINALS to the power amplifier:
Your F360 has two output channels that can be attached to power amplifiers which in turn, power the right and
left front speakers. Number 4 is the hookup for the RCA outputs going to a power amplifier. On number 5, the
output can be used with XLR cables to the amplifier. Again, be sure to observe the proper polarity, i.e., the right
channels of the preamplifier are connected to the corresponding right channels of the power amplifier.
6: BACK output terminal for the REAR speakers:
Number 6 is the RCA output connection to the amplifier used to power the rear speakers.
7: SUBWOOFER output terminals:
Number 7 are two subwoofer RCA connections to a powered subwoofer. PLEASE note there two outputs one
for stereo connection or a mono connection.

10
9: AC power connection:
The F360 preamplifier must be connected to a wall AC power receptacle, or a similar heavy-duty source. Avoid
the use of extension cords. If they must be used on a temporary basis, use a 14-gauge or heavier cord. The
power cord on your Fusion Pre-amp has a standard three-prong plug to provide maximum safety when it is
connected to a wall receptacle. If there is any question regarding the safety of grounding procedures, be certain
to seek competent help with the installation.
In the lower half of the IEC part is the fuse holder with a spare fuse. When replacing the fuse, the AC cord must
be removed from the unit. To remove the fuse holder, take a small flathead screwdriver and gently pry out the
holder as if it were tray that slides straight out. When replacing the fuse, for 110 - 120 VAC (Household AC
current) use a 1 amp slow blow fuse and for 200-240 VAC use a 0.5 amp slow blow fuse.
11: Main Power Switch:
IMPORTANT NOTE: Use the best available speaker wires and interconnects between your equipment. Our
experience has been that a set of top-quality cables hooked up to speakers, amplifiers and CD players can
improve the sound. Bet you already knew that.
Remote Control:
Included with the unit is a four button
metal remote control. When pressed:
1. The Standby button will turn the amplifier on from
standby and when the unit is on, revert to standby.
2. The V- button turns the volume down and the V+
button turns the volume up.
3. The mute button turns the sound off.

Tubes:
This section is dedicated to those who do not have an abundant amount of experience with tube preamplifiers
and amplifiers. Your preamplifier uses a 6SN7 vacuum tube.
These tubes are readily available at Specialty Audio stores in your local area, mail order houses for guitar and
audio equipment, and local Guitar Amplifier Stores, as well as the internet (type in vacuum tube). Black Ice
Audio tubes can be purchased from your dealer or we can help you locate a source for the vacuum tube you
need. Our experience is that the 6SN7 should last 8,000 hours. There is no exact method for determining the
life of the tube since the life expectation is a combination of how the tube was built, how it is used, and how long
it is operated.
Handling a tube preamplifier is not complicated even though most people are used to solid state. Replacing
tubes every nine years or more is not difficult. What you get with a tube preamplifier is a reliable piece of
electronic equipment that can give you years of service. Many people remember tube equipment in terms of old
radios in the 1940s and 1950s. However, in the past, tube equipment was known for its reliability and, in fact,
vacuum tubes currently are still in widespread use. Radar, microwave ovens, ham radios, guitar amplifiers, cat
scanners, X-ray machines, plastic sealing machines and power radio transmitters, to name a few types of
equipment, still use vacuum tube technology.
The real reason to have vacuum tubes in a preamplifier is the quality of sound it produces. There has been a
perennial debate over whether solid state preamplifiers sound better than vacuum tube preamplifiers. To be
sure, solid state proponents also have pointed to the problems of tubes in terms of hot vacuum tubes that can
burn you or your children and the need to replace the tubes. However, the critics of tube cannot argue against
the beauty of sound reproduction. A tube amplifier matched with an appropriate preamplifier can produce a
magical sound. The hard, brittle and edgy presentation of solid state is in sharp contrast to the rich, lush liquidity
and sound presentation or sound stage of a tube. The midrange and treble are smooth and silky with crystal
clear sound definition. As for bass, solid state can produce a harder bass sound; but a good tube system can
still deliver a punch in the lower end. Simply put, try it, you may like it.
Replacing Your Tubes
When you replace the vacuum tubes in your unit,
1. Should you replace your tube make certain the F360 is unplugged from the wall AC receptacle and make
certain the unit has not been operating for at least thirty minutes. This allows the capacitors to discharge and
the tubes to cool down.
2. To remove a vacuum tube, remove the top to expose the tube. Then use your thumb, index finger and middle
finger to gently grasp the vacuum tube on all sides. Hold the tube in the same manner as you would hold a
incandescent light bulb. To extract the tube from the socket, gently rock the tube from side to side while pulling
up on it until the tube pins have been freed from the socket. Never use excessive force.
3. When replacing the tubes, make certain that the pins match the socket holes.
Servicing
Because of its careful design and exacting standards of manufacture, your F360 should normally require only
minimal service to maintain its high level of performance. Should you require assistance with your unit, please
contact Black Ice Audio.
CAUTION: The F360 preamplifier contains sufficient levels of voltage and current to be lethal. Do not tamper
with a component or part inside the unit. Even with the power turned off, a charge remains in the energy storage
capacitors for some time. Refer any needed service to your authorized dealer or other qualified technician. In
essence, what we are saying, please do not fool around with the inside of the unit unless you know what you are
doing.
