Unpacking the CDP			Unpacking and Placement
			Unpack your CDP Compact Disc Processor and remove all accessories from the
			carton.
Important!			Keep all packing materials for future transport of your CDP.
			Shipping your new component in anything other than its
			purpose-designed packing material may result in damage
			that is not covered by the warranty.
Remove the Transport Screw
			Place the CDP Compact Disc Processor upside-down on a soft, clean surface. Re-
			move the transport screw from the bottom of the unit and save it with the pack-
			ing materials for future use.
Warning!			The transport screw must be removed before operating the
			CDP, since it immobilizes the transport mechanism during
			shipping to prevent damage. This screw must also be
			replaced before shipping the unit.
Placement of the CDP
			The CDP should be placed close to your preamplifier, thus keeping interconnect
			cabling reasonably short. It may be placed on a shelf or in a cabinet where it is
			convenient to operate.
			Drawings are included in this manual to facilitate special installations and custom
			cabinetry (see Dimensions).

Operating Voltage

& Frequency

The CDP Compact Disc 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/50Hz only in European Union countries, in compliance with CE regulations.) Make sure that the label on the rear panel of the CDP (beside the AC input receptacle) indicates the correct AC operating voltage for your location. Attempting to operate the CDP at an incorrect voltage can damage the unit.

Neither the voltage nor the line frequency setting may be changed by the user.

A Quick Start…

We recognize that many people are understandably eager to begin listening to their new components, and that reading the manual is often done (if at all) at a later time—perhaps while listening to music with the new product itself. We strongly recommend that you read this manual thoroughly, as the CDP Compact Disc Processor incorporates many unusual features that enhance its operation.

Fortunately, we can help you get some music up and running on your system quickly, so that you may begin enjoying your new CD player while reading more about it. The goal here is simply to make some music as quickly as possible. The following procedure assumes that the rest of your system is already connected (e.g., preamplifier to power amplifier, to speakers), and that you are using the CDP as a CD player rather than as a digital preamplifier.

1TURN OFF YOUR ASSOCIATED COMPONENTS

This minimizes the opportunity for a momentary electrical surge disturbing your system while making connections. If you have a large power amplifier, allow its power supply to fully discharge before proceeding (which may take as long as several minutes, depending on its design).

2REMOVE THE TRANSPORT SCREW FROM THE BOTTOM OF THE CDP

If you have not done so already, remove the knurled transport screw from the bottom of the CDP now. Be sure to save it and all packing material for possible future use. (Tip: consider taping it to the rear of the unit so it will be found the moment you need it.) Shipping the CDP without proper packing material and without the transport screw in its proper position may cause damage to the unit that would not be covered by the warranty.

3CONNECT THE CDP TO AC POWER

Connect the AC cord to the CDP at the receptacle on the rear panel, and then to your AC outlet. Depress the front panel power button. The CDP will take a few moments to initialize.

4CONNECT THE LEFT AND RIGHT OUTPUTS TO APPROPRIATE INPUTS ON YOUR PREAMP

The CDP provides for both balanced and single-ended interconnection (via XLR and RCA connectors, respectively). Choose either the balanced (preferred) or single-ended outputs, and connect them to a line-level input on your preamplifier (probably labeled “CD” or some such), using high quality cables.

5POWER UP THE REST OF THE SYSTEM (POWER AMPLIFIER LAST)

Always turn the power amplifier(s) off first, and on last. This good habit minimizes the opportunity for unexpected transients to be passed to your loudspeakers. (Another good habit: turn the volume down on your preamp before turning it back on.)

	6	SELECT THE INPUT YOU ARE USING ON YOUR PREAMPLIFIER
		Take care that a Tape Monitor switch does not override your selection of
		the input on your preamplifier, or you will be struck by how “quiet” your
		new CD player is.…
	7	LOAD A DISC IN THE DRAWER AND PRESS PLAY; SLOWLY RAISE THE
		VOLUME ON YOUR PREAMPLIFIER
		Congratulations! You should now be able to enjoy your favorite music while
		reading the rest of this manual. (Please, do read the rest of this manual.)
Warm up/break-in period	Although your Proceed CDP Compact Disc Processor delivers outstanding perfor-
	mance straight out of the box, you should expect to hear it continue to improve
	as it reaches its normal operating temperatures and its various components
	“break-in.” It has been our experience that the greatest changes occur within the
	first 300 hours as the CDP reaches thermal equilibrium and the capacitors fully
	form. After this initial break-in period, the performance of your new product
	should remain quite consistent for years to come.
	The only exception to this rule is if power is removed from the unit for an ex-
	tended period of time, allowing it to cool down. Depending on the degree of
	cooling involved, you should expect a brief warm-up period before the CDP’s
	sound quality is at its best. Unless your CDP was allowed to become quite
	chilled, subsequent thermal re-stabilization should not take long.
Using the CDP as	The CDP incorporates two digital inputs for use with digital sources such as
a digital processor	laserdisc players, digital recorders, and digital cable radio systems. These digital
	inputs use the digital audio processor in the CDP. In relatively straightforward sys-
	tems with only one or two digital sources beyond the CD player itself, the CDP
	may be the only digital processor needed.
	You may access either of the digital sources connected to the two auxiliary digital
	inputs on the CDP by pressing source on the remote control. This action cycles
	through the CD transport portion of the CDP, to Input 1 (the S/PDIF input), to In-
	put 2 (the EIAJ input), then returning to the CD.
Using the CDP as	Since the CDP already includes some input selection capabilities, the addition of
a digital preamp	a high quality volume control turns it into a combination CD player/digital
	preamplifier. In simple systems consisting only of three or fewer digital sources,
	amplification and loudspeakers, the CDP may be the only control center needed.
	Most owners of the CDP will also have analog sources (radio, tape, VCR, etc.) and
	will therefore require an analog preamplifier. For this reason, the CDP’s volume
	control circuitry is bypassed by default (as shipped from the factory). But if you
	would prefer to use the CDP’s volume control circuitry, you may enable it in the
	Setup menu. Please see Customizing the CDP, later in this manual for details.

Special Design Features

Congratulations on your purchase of the CDP Compact Disc Processor. The Madrigal design team is confident you will enjoy the outstanding performance of the CDP 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 CD player.

Transport Design The first portion of any CD player it its transport: the mechanism by which information is recovered from the disc itself and made ready for conversion to analog. The characteristics of an outstanding CD transport are simple to define: it must recover the correct data from the disc, and deliver it to the digital processor portion of the CD player without any timing errors (sometimes called “jitter”). As simple as this sounds, achieving it in reality has been extremely difficult—as evidenced by the significant sonic differences between various CD transports.

Conventional CD transport design depends on the quality of the oscillator used to control the rate at which the disc itself spins. This oscillator exists in an extremely “noisy” electrical environment close to the motor that spins the disc. The electrical noise introduces timing errors in the delivery of the digital signal that have come to be known as “jitter.” Subsequent handling of the digital audio signal in traditional transport designs cannot improve upon this “jittery” signal, lacking a better reference. To the contrary, the various stages of signal processing between the laser pickup and the final output can only contribute additional jitter of their own.

The Proceed CDP leaps beyond conventional digital audio technology by employing a proprietary, closed-loop jitter-reduction system in conjunction with a double speed CD-ROM drive. Using a custom-made crystal oscillator with better than five part-per-million accuracy, the digital signal is reclocked immediately before being sent to the digital to analog converters, eliminating transport-related jitter from the digital audio signal. This same crystal oscillator controls the all-digi- tal servo used to control the rate at which the disc spins, and the digital to analog conversion process.

In effect, the design of the CDP turns the accepted status quo on its head. By placing the all-important reference clock immediately prior to digital to analog conversion, and slaving both the mechanical subassemblies and the digital to analog converters to it rather than the other way around, the signal presented to the outputs of the CDP is virtually uncontaminated by jitter. The sonic advantages of this design are immediately apparent in the clarity, warmth and stunning dynamic contrasts exhibited by the CDP.

Digital Servo Control The laser mechanism used in the CDP uses all digital servo controls of its operations. Critical functions such as focus and tracking are handled completely in the digital domain with mathematical precision. Whereas conventional, analog servos require periodic realignments for optimum performance (to compensate for the aging of various analog components), a digital servo remains stable over time, never needing readjustment under normal conditions.

Input/Output Versatility The CDP incorporates two digital inputs, allowing two external digital sources such as a laserdisc player and a digital recorder to benefit from the excellent digi-

10

tal processor that is incorporated within. The two most common digital interfaces are supported for the widest compatibility: eiaj optical (sometimes called “TosLink™”) and s/pdif electrical, via an RCA connector.

A high quality S/PDIF digital output is also provided via an RCA connector. This digital output may be used to feed the selected source signal to the input of a digital recorder or to an outboard digital processor. (This output benefits from the closed-loop jitter reduction circuitry described above when the CD transport is the selected source.)

Fully balanced design The CDP is fully balanced in both the analog and digital domains. The auxiliary, single-ended digital inputs are immediately converted to balanced signals before any further routing or processing of the signal. 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 CDP 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.

Volume Control The CDP’s volume control may be enabled in the Setup menu (see Customizing the CDP). Through most of the useful range of this scale, the increments are slightly more than 1⁄2 dB per step, providing excellent volume resolution. Significantly, this volume control circuitry uses an advanced hybrid analog and digital design that avoids the sonic penalties associated with purely digital volume controls.

Industrial Design The CDP shares the handsome industrial design of other Proceed components such as the PRE preamplifier. Dark buttons against a light face simplify the operation of the CDP, even in a dimly-lit room. The large, easily read display provides information as to the operational status of the CDP from across the room, making the supplied remote control more genuinely useful than on products lacking such a display.

In keeping with its sophisticated design, the CDP also incorporates a Madrigaldesigned loading mechanism. Contrasting strongly with the bulky, plastic drawers commonly used, the slim 1⁄8 inch drawer is machined from a solid piece of aluminum and rides on highly polished steel and Teflon™ bearings. Its variable-speed design opens and closes quickly, but without jarring the disc contained within, nor risking a jam from dislodging it.

1POWER & POWER LED

Assuming that the CDP’s power cord is connected to AC power, pressing this latching power button connects the CDP to the AC mains and turns on the unit. When power is restored after an interruption, the CDP will be ready to operate (that is, it won’t be in standby mode), after a few moments’ delay to allow its circuits to stabilize.

While the CDP is in standby (see 9, below), the LED above the power button is red. When the CDP 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.

2PROGRAM – AND PROGRAM + BUTTONS

Using these two buttons, the CDP can be easily programmed to play a special “playlist,” or sequence of tracks, on any particular disc. Pressing program + adds a selection to a program (or advances through an existing playlist when reviewing a program you have already created).

Alternatively, it may be simpler to omit the one or two songs that you have heard too many times on the radio, playing the rest of the tracks in order. Pressing program – will delete the selected track from the playlist, omitting it on playback.

A program may be entered any time a disc is in the CDP and the unit is in the stop mode. For detailed information on programming the CDP, see Programming the CDP later in this manual.

12

	3	PREV/REW BUTTON
		Pressing this button momentarily will return you to the beginning of the
		current track. Pressing it repeatedly will move you backward through the
		available tracks, one at a time. Pressing and holding this button will instead
		perform a reduced-volume reverse scan of the music, reminiscent of the
		audible rewind function found on many cassette decks. This scanning mode
		allows you to quickly find a particular point within a track.
		(Note that if you press prev/rew within two seconds of the beginning of a
		track, the CDP will assume that you meant to go further back and take you
		to the beginning of the previous track rather than the current track.)
	4	PLAY/PAUSE BUTTON
		Press this button in order to play a disc. If a programmed sequence of
		tracks exists for that particular disc, the program will be played from its be-
		ginning. Also, as you might expect, you may press the play button immedi-
		ately after placing a disc in the CDP’s drawer; the drawer will close and the
		CDP will enter the play mode as soon as it has read the disc’s table of con-
		tents.
		Pressing this button during play will pause the CDP at that point within
		the track; the time display will blink slowly as a reminder that you are in
		the pause mode.
the extended pause mode		After about two minutes in pause, the CDP will go automatically into an
		“extended pause” mode that stops the disc and turns off the laser against
		the possibility that you have been called away and may not return for some
		time. The extended pause mode is indicated by the display blinking more
		slowly than in normal pause. You may force the CDP to enter extended
		pause by pressing and holding the play/pause button for about five sec-
		onds.
		In effect, extended pause is much like stop, with the exception that press-
		ing play will return you to the point on the disc where you had left off lis-
		tening, after only a momentary hesitation to spin the disc back up to speed
		and scan to the appropriate point.
	5	NEXT/F.FWD BUTTON
		Pressing this button momentarily will advance the CDP to the beginning of
		the next track. Pressing and holding this button will instead perform a re-
		duced-volume fast forward scan of the music, reminiscent of the audible
		fast forward function found on many cassette decks. This scanning mode
		allows you to quickly find a particular point within a track.
	6	INFRARED TRANSCEIVER (WITHIN DISPLAY)
		Infrared commands transmitted from the remote control are received by a
		receiver behind this section of the display. Remote control of the CDP may
		be unreliable if there is not a clear line of sight between the remote control
		and the receiver (if the remote is far off-axis, or if the CDP is within a cabi-
		net, for example). In such a case consider using a third-party IR repeater to
		route the signal to the IR input jack on the rear panel (see Rear Panel, CDP,
		below).

13

In addition to receiving IR commands, the CDP has the ability to teach a learning remote control its own commands from an IR transmitter located in this same area. (See Using Learning Remote Controls for more information.)

7TIME INDICATOR

The time section of the display can be set to display any of the following four indications of time in minutes and seconds: time elapsed in track, time elapsed on disc, time remaining on disc, time remaining in track. These four options are accessed by pressing the display button to the right of the display (see 9, below), which cycles through the four modes of time display, using the on disc and time rem. LEDs to indicate which mode is chosen at any moment. When in stop, the indicated time will normally default to the total remaining time on the disc (or in the playlist for the current disc, if programmed). This time indication may be changed if desired once in stop.

8TRACK INDICATOR

The next two characters are used to indicate the number of the track being played. When a compact disc is loaded but the transport is in the stop mode, this same space indicates the total number of tracks on the disc (or in the program for the current disc, if programmed).

9MUTE INDICATOR

The CDP’s remote control includes a mute button to allow quick and easy reduction of the system’s volume when desired. The output level of the CDP will quickly reduce by a user-defined amount (approximately -20 dB as delivered from the factory) when mute is engaged. This LED flashes red while ramping the volume up or down on the CDP, then glows red continuously for the duration of muted playback. Pressing mute again will ramp the volume back to its previous setting.

Note:	The mute indicator will continue to operate even when the
	display is turned off, in order to avoid any unpleasant
	surprises (such as might happen when you attempt to mute
	an already-muted system, inadvertently raising the volume
	instead).

10DISPLAY BUTTON

The display button cycles through the four time display modes used to indicate where you are on the disc. These four display modes are:

• time elapsed in track		(neither LED lit)
• time elapsed on disc		(on disc LED lit)
•	time remaining on disc	(on disc and time rem. LEDs lit)
•	time remaining in track	(time rem. LED lit)
