Getting Started
About Your Glass FX Tube DAC DSD WIFI:
In electronics, a digital-to-analog converter (DAC or D-to-A) is a device that converts a digital (usually binary)
code to an analog signal (current, voltage or electric charge). Black Ice Audio’s Glass FX Tube DAC DSD WIFI is
an example of state-of-the-art in vacuum-tube technology, as it exists today. For your information, the DAC DSD
does not use Op Amps for increasing gain, the analog signal from the Digital chip is amplified by the vacuum
tubes giving the unit an organic presentation. This product was designed to provide: 1) a DAC that would deliver
musical accuracy 2) a significant value based on a high performance to price ratio and 3) an all-vacuum tube DAC
that would exceed the reliability of solid-state units.
The Glass FX DAC DSD WIFI is housed in a Heli-arc welded chassis and uses 2 pieces of 12AX7 tubes for the
preamplifier. The DAC can process PCM and DSD signals from 16, 24, and 32 bit and sample rates up to 384 Hz.
Parts quality is the best currently available, and the overall circuit layout is maximized for sonic purity. In critical
filter areas of the design, we have put Audiophile grade polymer capacitors and top grade ceramic composite
resistors.
Construction and Testing
Like every Black Ice Audio product, your DAC 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 Glass FX Tube DAC DSD WIFI is
visually inspected at several assembly points, test run, electronically tested and sound evaluated 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 will say they lack experience handling vacuum tubes. However, most people have handled incandescent
light bulbs, which is 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 taken 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, Inc. DAC is a precision electronic instrument and
should be properly packaged any time shipment is made. 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.
Unpacking
The Glass FX Tube DAC DSD WIFI is packed within a impact absorbing foam wrap that holds the amplifier in
place. Because of the unit weight and because it is a precision electronic instrument, reasonable care should be
taken when unpacking the unit and preparing it for use. The carton should be set upright in the center of the work
area and outer carton's top flaps can be lifted up. Lift out the foam on top of the DAC. The DAC can be lifted out
of the box and the plastic wrap removed.

Preparation for Use
1. Place your DAC on a flat surface.
2. Your DAC is shipped with the tubes already installed. Gently push on the tubes to make sure they are properly
seated. Please note, in removing or putting in new tubes, make sure the pins of the tube are lined up with the
holes in the socket and never use excessive force when putting the tube into the socket.
3. Please Note if you are using a computer with Windows, you will have to go to our web site and
download the drives. For those who have a MAC computer, you will not have to load a driver.

For setting up the WIFI please go to Appendix One.
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 DAC is properly connected to a high-current power receptacle via the attached power cord
(see Connections).
3. Attach the audio sources and amplification to the Glass FX Tube DAC.
4. Your Glass FX Tube DAC will now operate satisfactorily. However, a full stabilization or warm-up period of at
least 5 minutes is recommended for best sonic performance.

Controls and Their Functions
Front Panel
POWER switch:
Press switch to turn the power on. One of the selector indicators should light up to blue indicating the unit is
ready for operation. Within a few seconds, the tubes will begin to glow a soft color. Press the switch down to
turn the unit off.
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 away from the unit.
Further, other source components of an audio system should be turned on first. Otherwise, with some equipment,
the amplifier will reproduce warm-up thumps.
Volume Knob:
To increase the volume, turn the knob counterclockwise and conversely, to decrease the volume, turn the knob
counterclockwise. The volume knob is a convenience that allows the DAC DSD to be used with a power amplifier
or amplified speakers, If the unit is to be used with an integrated amplifier or a preamplifier, then the volume knob
can be turned to 3 o’clock or the maximum.
SELECTOR button:
Used to select the audio source to be heard. There are three selection positions that can be chosen by pressing
the selector button. The positions are USB, Toslink, and coaxial and WIFI.
Headphone Jack:
The DAC WIFI has a mini jack which can be used with headphones. The volume control will operate the level of
volume on the headphones. If the DAC is also attached to a powered amplifier, the DAC will still send a signal to
the powered amplifier. If you wish to use only the headphones, then either turn the power amplifier off or
disconnect the RCAs to the amplifier.

Ground Post
Can be utilized as a grounding source for other pieces of electronic equipment
DAC power connection and fuse
Always place the power on-off switch on the panel of the Glass FX DAC DSD WIFI in the "Off" position before
connecting the power line cord to AC power. The DAC 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 14-
gauge or heavier cords. The power cord on your DAC has a standard three-prong grounding plug to provide
maximum safety when it is connected to a ground wall receptacle. If there is any question regarding the safety of
grounding procedures, be certain to seek competent help with the installation. In the upper half of the IEC is the
fuse holder with an extra fuse. When replacing the fuse, make sure that your DAC unit is unplugged from the
amplifier. To replace the fuse, slide the cover off with a fingernail file as if you were pulling out a tray. Use the
fuse in the covered portioned and replace the non-working fuse. For 110 - 120 VAC (Household AC current) a 0.5
amp slow blow fuse (5 mm X 20 mm size) and for 200-240 VAC use a 0.25 amp slow blow fuse.

In General:
Use the best available speaker wires and interconnects between your equipment. This material is available at
your local audio store. Black Ice Audio cannot emphasize this enough. Our experience has been that a set of top-
quality cables hooked up to speakers and amplifiers can improve the sound. Your amplifier uses a complement of
2 pieces of 12AX7 tubes.
These tubes are readily available at Specialty Audio and Music Instrument stores in your local area, Internet and
mail order houses for guitar and audio equipment, and even on eBay. The majority of professional guitar
amplifiers sold are tube driven since the music industry uses the best sounding amplifiers for professional
reasons. Internet sites selling vacuum tubes can be found by typing in vacuum tube in the search function. The
mail order houses can be found in magazines such as Stereophile, Absolute Sound, Guitar Player and Guitar
World. 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 12AX7s should last 6,000 hours or up to 10 years. 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 is not complicated even though most people are used to solid state. Replacing tubes every six
years or more is not difficult. What you get with a tube DAC 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. The picture screen of your television and computer monitor is a CRT or cathode ray tube.
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 an DAC is the quality of sound it produces. There has been a perennial
debate over whether solid-state sounds better than vacuum tubes. To be sure, solid state proponents also have
pointed to the problems of tube amplifiers in terms of hot vacuum tubes that can burn you or your children and the
need to replace the tubes. However, the critics of tubes cannot argue against the beauty of sound reproduction.
The hard, brittle and edgy presentation of many solid-state DACs is in sharp contrast to the rich, lush liquidity and
sound presentation or sound stage of a tube DAC. 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 amp can still
deliver a punch in the lower end. Simply put, have your friends listen to the sound; of a tube DAC and they will
probably want to know where you purchased it.
We have often been questioned regarding the benefits of tube rolling, which we define as using tubes in the units
from different production lines to improve sound. Many will extol the virtue of one tube over another, but we would
suggest that changing the make of the tube does not necessarily improve the sound; rather it will change the
sound. One of the practical beauties of a tube amp is that the sound can be modified to the listener’s preference
through the change of tubes. For example, one tube can add clarity, and another will be smoother. We think the
permutations of different sounds is in direct relation to the variety of tubes on the market. And, most importantly,
the issue is not whether one tube is better than another; the issue is whether you like the sound of the tube.
Before delving in the black art of tube rolling, we suggest that you use the stock tubes for about three months.
Listen to different music in terms of producer and type of music. Every so often listen critically and ask the
question, what sound characteristic would increase your listening pleasure. If a pattern makes itself known, then
you can pass this information to a tube seller who will be able to focus on a make of tubes that will get you in the
direction of your listening goals.

10
Replacing/Changing Your Tubes
1. When you replace your tubes make certain the amplifier is unplugged from the wall AC receptacle and make
certain the unit has not been operating for at least thirty minutes. This allows the capacitor to discharge and the
tubes to cool down.
2. To remove a vacuum tube, 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 right part is being placed in the socket, e.g., 12AX7, etc. The
socket has nine holes with a space and the tube has nine pins with a space. Holding the tube with the thumb,
index finger and middle finger, line up the ins of the tube with the nine holes of the socket. Gently push the tube
into the socket until it is seated. Never try to force the tube into the socket. If the tube does not go easily into the
socket, check to make certain the pins are lined up, straight and that you are using the right tube.
Servicing
Because of its careful design and exacting standards of manufacture, your Glass FX Tube DAC DSD WIFI should
normally require only minimal service to maintain its high level of performance.
CAUTION: The Glass FX Tube DAC DSD WIFI 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 Black Ice Audio dealer or
other qualified technician.
The vacuum tubes in the DAC are high-quality 12AX7 types. Replacement tubes should be matched for best
sonic performance, although that is not a requirement for good sound. Reliable, low gas tubes such as those
available from Black Ice Audio are strongly recommended for maximum performance and longevity.
Questions regarding your amplifier may be referred to the Customer Service Department of Black Ice Audio: (301)
