Congratulations, you have very good taste in audio equipment. The Lucid Technology ADA1000
analog to digital & digital to analog converter will provide you with the cutting edge in 20 bit sound
quality which, until recently, was limited to professional audio producers with large budgets.
This manual will lead you through connecting the ADA1000 and assist you in understanding its
functions. It is assumed that you are reading this manual after purchasing the ADA1000 and that
you have a basic understanding of digital audio.
The ADA1000 has been built to the highest standards of performance and reliability. Should you
have any questions regarding the ADA1000 or any other Lucid Technology product, please feel free
to contact us.

The lightning flash with arrowhead symbol within an
equilateral triangle is intended to alert the user of the
presence of uninsulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user of the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the product (i.e. this manual).
Caution To prevent electric shock, do not use the polarized plug
supplied with the unit with any extension cord, receptacle, or other outlet unless the blades can be fully inserted.
Terms
Several notational conventions are used in this manual. Some paragraphs may use Note, Caution, or
Warning as a heading or certain typefaces and capitalization are used to identify certain words. These are:
Note Identifies information that needs extra emphasis. A Note generally supplies extra information to help you
to better use the product.
Caution Identifies information that, if not heeded, may cause damage to the Lucid product or other equipment in your system.
Warning Identifies information that, if ignored, may be hazardous to your health or that of others.
CAPITALS Controls, switches or other markings on the product’s chassis.

Important Safety Instructions
Please read and keep these instructions. Heed and follow all warnings and instructions.
Power Source This product is intended to operate from a power source that does not apply more
than 250V rms between the power supply conductors or between either power
supply conductor and ground. A protective ground connection, by way of the
grounding conductor in the power cord, is essential for safe operation.
Grounding The chassis of this product is grounded through the grounding conductor of the
power cord. To avoid electric shock, plug the power cord into a properly wired
receptacle before making any connections to the product. A protective ground
connection, by way of the grounding conductor in the power cord, is essential for safe
operation. Do not defeat the safety purpose of the grounding plug. The grounding
plug has two blades and a third grounding prong. The third prong is provided for your
safety. When the provided plug does not fit your outlet, consult an electrician for
replacement of the obsolete outlet.
SECTION 2

Danger from Loss of Ground
If the protective ground connection is lost, all accessible conductive
parts, including knobs and controls that may appear to be insulated, can
render an electric shock.
Proper Power Cord Use only the power cord and connector specified for the product and your
operating locale. Use only a cord that is in good condition. Protect the power
cord from being walked on or pinched, particularly at plugs, onvenience
receptacles, and the point where they exit from the apparatus.
Operating Location Do not operate this equipment under any of the following conditions:
explosive atmospheres, in wet locations, in inclement weather, improper or
unknown AC mains voltage, or if improperly fused. Do not install near any heat
source such as radiators, heat registers, stoves, or other apparatus (including
amplifiers) that produce heat. Unplug this apparatus during lightning storms or
when unused for long periods of time.
Stay Out of the Box To avoid personal injury (or worse), do not remove the product covers or
panels. Do not operate the product without the covers and panels properly
installed. Only use accessories specified by the manufacturer.
Clean only with a damp cloth.
User-serviceable Parts There are no user serviceable parts inside the ADA1000. In case of
failure, refer all servicing to the factory. Servicing is required when the
ADA1000 has been damaged in any way, such as when a power supply cord or
plug is damaged, liquid has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does not operate normally,
or has been dropped.

SUMMARY PRODUCT DESCRIPTION
This section of the manual provides an overview of the functions and controls of the ADA1000.
Please see the ANALOG INPUT/OUTPUT CONNECTIONS section (page 9) of this manual for wiring
and connections.
FRONT PANEL:
The front panel of the ADA1000 has three main sections: The INPUT LEVEL CONTROL section, the
D/A STATUS INDICATOR section, and the A/D SAMPLE RATE SELECTION section.

ANALOG INPUT
LEFT CHANNEL (LINK)
This section contains the analog
input controls for the left and
right analog inputs.
Input Level Control:
SIGNAL PRESENT INDICATOR LED - This indicator shows the existence of analog input. The LED
will light when signal level of - 40dB or greater is detected.
HEADROOM METER - This signal level meter is incremented in 4 dB steps. Please notice that this is
a headroom meter designed to show the amount of signal headroom level before digital clipping (full
scale). As with all analog to digital converters, it is best to run the signal as high on the headroom
meter as possible without hitting the clip point.
NOTE:
Digital clipping results when incoming analog signals overdrive the ADA1000’s A/D converter. For best
results, test the audio coming into the ADA1000 for the highest peaks and adjust INPUT LEVEL controls so
peaks do not light the clip LEDs.
CHANNEL INPUT LEVEL CONTROLS - The left and right channel input knobs are used to control
the signal level coming into the analog inputs of the ADA1000. These controls operate over a 15 dB
range. In STEREO LINK mode, the Left Channel input control becomes the master control for both
left and right inputs.
NOTE:
Descriptions of these controls apply to
both channels.

SIGNAL PRESENT LED - Lights to show that there is valid AES/EBU
or S/PDIF format digital signal at the ADA1000’s digital input port.
This is especially useful to verify that the connections are correct when
first hooking up the ADA1000 to a digital device. The ADA1000’s D/A
circuitry automatically locks to the sample rate of the incoming digital
bit stream.

ANALOG OUTPUTS - These connections
are for sending the analog signal from the
D/A converter to external audio devices for
transfer or monitoring. Both balanced XLR

Only one cable is needed for digital
stereo information. See ANALOG
INPUT/OUTPUT CONNECTIONS (page
9) for connector pinouts.
S/PDIF - AES/EBU SELECTION SWITCH - When the button is pressed in, the ADA1000 will
process the information as AES/EBU format. When the button is released (the out position), the
digital section will process the signal as S/PDIF information.

Servicing your Lucid product
For US Customers:
If you have determined that your Lucid product requires repair services and you reside in the US,
please contact our Customer Service Department for a return authorization (RA) number. Phone
[phone], Monday through Friday, 6AM (0600 hours) though 5PM (1700 hours) Pacific
Time.
If the warranty period has passed, you’ll be billed for all necessary parts, labor, packaging materials,
and freight charges. Please remember, you must call for an RA number before sending the unit to
Lucid.
For International Customers:
If you live outside of the United States, please contact your local Lucid dealer or distributor for
instructions on how to obtain service.
Begging and Pleading
WAIT! Before you toss this guide away, we’d like to offer you a blatant bribe. How does two extra
years of free warranty coverage sound? Good, huh? Just fill out and mail your completed product
registration card. Three full years of warranty coverage can be yours just that easily.
If you don’t register your product, we’ll still give you one year of warranty coverage, but it only takes
a minute to fill out the card. We promise that we won’t share your personal information with
anyone else. So what’s to lose?
