Important Safety Instructions
Please read all instructions and precautions carefully and completely before operating your DAP digital audio
processor.
1. ALWAYS disconnect your entire system from the AC mains before connecting or disconnecting
any cables, or when cleaning any component.
2. This product is equipped with a three-conductor AC mains power cord which includes an
earth ground connection. To prevent shock hazard, all three connections must ALWAYS be

If an adapter is necessary, be sure it is an approved type and is used properly, supplying an
earth ground. If you are not sure of the integrity of your home electrical system, contact a licensed electrician for assistance.
3. AC extension cords are not recommended for use with this product. If an extension cord must
be used, be sure it is an approved type and has sufficient current-carrying capacity to power
this product.
4. NEVER use flammable or combustible chemicals for cleaning audio components.
5. NEVER operate this product with any covers removed.
6. NEVER wet the inside of this product with any liquid.
7. NEVER pour or spill liquids directly onto this unit.
8. NEVER block air flow through ventilation slots or heatsinks.
9. NEVER bypass any fuse.
10. NEVER replace any fuse with a value or type other than those specified.
11. NEVER attempt to repair this product. If a problem occurs, contact your Proceed
12. NEVER expose this product to extremely high or low temperatures.
13. NEVER operate this product in an explosive atmosphere.
14. ALWAYS keep electrical equipment out of the reach of children.

Unpacking and Placement
Unpacking Unpack your Proceed
rials for future transport. Locate and remove the AC power cord from the
cardboard slot it occupies within the shiping carton.
Placement Place the DAP near the source equipment, thus keeping interconnecting cables
(both digital and analog) reasonably short. It may be placed on a shelf or in a
cabinet where it’s convenient to operate.
Note that adequate clearance for the AC cord and connecting
cables must be left behind the DAP. We suggest leaving at least three
inches of free space behind the DAP to allow all cables sufficient
room to bend without crimping or undue strain.
Ventilation Be sure to allow 2 to 3 inches of clearance above the DAP to allow heat dissipa-
tion through air circulation.
Mechanical drawings are included in this manual to facilitate special installations
and custom cabinet work (see “Dimensions” at the end of this manual).

PRECAUTION
For your protection, review “Important Safety Instructions”
before you install your DAP.

Operating Voltage
The DAP digital audio processor is set at the factory (internally) for 100V, 120V,
200V, 220V, or 240V AC mains operation as appropriate for the country in which
it is to be sold. (230V only in European Union countries, in compliance with CE
regulations.) Make sure that the label on the rear of the DAP indicates the correct
AC operating voltage for your location. The operating voltage cannot be changed
by the user, and any attempt to do so will void the warranty.
If the voltage indicated is incorrect relative to that supplied in your area, see your
Proceed dealer.
WARNING: BEFORE ATTEMPTING TO OPERATE THIS DEVICE,
REFER TO OWNER’S MANUAL FOR PROPER OPERATING
INSTRUCTIONS AND SAFETY PRECAUTIONS. HAZARDOUS

Special Design Features
Congratulations on your purchase of the Proceed DAP. The Madrigal design team
is confident you will enjoy the outstanding performance of the DAP for many
years. In case you are interested in technical details, what follows is a brief outline of some of the key technologies in your new processor.
Superior isolation
between sources
Fully balanced design The DAP is fully balanced in both the analog and digital domains. Even single-

One of the advantages of a separate digital audio processor is that you can take
the money which might have otherwise been spent on several built-in D/A converters and put it into one, superior processor which will enhance the performance of all the transports with which it is used. Ironically, many outboard processors fail to live up to this potential due to interference between their various
digital inputs.
The DAP provides outstanding isolation between its inputs, realizing the full potential of the various digital transports with which it is used. In fact, all unselected digital inputs are capacitively shunted to ground upon entering the DAP to
prevent their interaction with any portion of the circuitry inside the processor. As
a result, the selected input effectively has the DAP “all to itself” for its conversion
to analog.
ended digital inputs (anything other than the balanced aes/ebu standard) are immediately converted to balanced signals before any further routing or processing
of the signal. All digital filtering and processing is implemented in a balanced
configuration, and conversion to analog is accomplished in two opposing polarity
18-bit converters per channel.
This approach maintains the integrity of the signal, reducing the opportunities for
music-destroying noise and digital artifacts to enter the signal path.
24 bit digital architecture
and HDCD
®
compatibility
All digital filtering and processing maintains a true 24-bit throughput capability,
providing greater digital resolution than any existing source component. Even the
most stringent requirements of professionals can easily be met with this design.
In addition, the DAP also incorporates High Definition Compatible Digital® decoding to take full advantage of the increased resolution available from HDCD
encoded 16-bit CDs. The High Definition Compatible Digital® format retains much
of the resolution inherent in professional twenty bit recordings by encoding this
information more efficiently within the sixteen bit space available within the
Compact Disc format.

1 STANDBY & STANDBY LED
Assuming that the DAP’s power cord is connected to AC power, pressing
the standby button toggles the unit between standby and operate. When
first powered up, or when power is restored after an interruption, the DAP
will be in standby; pressing this button will bring it out of standby.
While the DAP is in standby, the LED above the standby button is red.
When the DAP is ready to operate (that is, when it is not in standby
mode), this LED is amber. Naturally, when AC power is off, the LED is off.

The benefits of having the DAP always warmed up and ready to go (and
able to respond to a remote control) far outweigh the small amount of
power used while the unit is in standby. We recommend unplugging the
DAP only when you will be away from the house for an extended period
of time (such as during a vacation), or during electrical storms.
2 MAIN DISPLAY
The main display provides information pertaining to the operation of the
DAP, and is used in conjunction with the up/down buttons beside it. Nor-
mally, the main display indicates the number of the selected digital input (1
through 5) and the sampling frequency it is currently locked on (32, 44, or
48 kHz).
If an HDCD® recording is played, the display will flash hd and cd several
times, and then remain on hd to indicate that decoding is taking place.
If the DAP is placed into its variable output mode, the main display will
indicate the relative volume on a scale of 0–99. (See the discussion of the
mode button, below.)
