Unpacking and Placement
Unpacking Unpack your Proceed® DAP digital audio processor and keep all packing materials 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 dissipation 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.

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 out- |
|
line of some of the key technologies in your new processor. |
Superior isolation |
One of the advantages of a separate digital audio processor is that you can take |
between sources |
the money which might have otherwise been spent on several built-in D/A con- |
|
verters and put it into one, superior processor which will enhance the perfor- |
|
mance of all the transports with which it is used. Ironically, many outboard pro- |
|
cessors 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 po- |
|
tential of the various digital transports with which it is used. In fact, all unse- |
|
lected 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. |
Fully balanced design |
The DAP is fully balanced in both the analog and digital domains. Even single- |
8 |
ended digital inputs (anything other than the balanced aes/ebu standard) are im- |
|
mediately 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 |
All digital filtering and processing maintains a true 24-bit throughput capability, |
and HDCD® compatibility |
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® de- |
|
coding 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. |

Front Panel
1 STANDBY & STANDBY LED
Assuming that the DAP’s power cord is connected to AC power, pressing 9 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.
2MAIN 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. Normally, 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.)
