Unpacking and Placement

unpacking the

Video Preamplifier. Shipping your new component in anything other than its purpose-designed packing material may result in damage that is not covered by the warranty.

unit on and off, selecting something to listen to or watch, and adjusting volume. It is designed to make day to day operation of the system as simple as possible.

Alternatively, you may decide that you would prefer to have a more powerful or versatile remote control. Your dealer can assist you in selecting a learning remote control that is appropriate to your needs, and can then teach the new remote control all the necessary AVP commands from the AVP itself. The AVP can transmit as well as receive IR commands, and its menu system contains an extensive list of available commands for learning remote controls (going far beyond what is normally available in such products).

placement Place the Audio Video Preamplifier near the digital sources, thus keeping inter-

connecting cables 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 Audio Video Preamplifier. We suggest leaving at least three inches of free space behind the Audio Video Preamplifier to allow all cables sufficient room to bend without crimping or undue strain.

ventilation It is normal and perfectly safe for your Audio Video Preamplifier to run quite

warm. Be sure to allow 2 to 3 inches of clearance above it to allow heat dissipation through air circulation. The vents on both the bottom and the top of the Audio Video Preamplifier must be kept free from any obstruction which would reduce the flow of air through the unit. Avoid placement on soft surfaces that would restrict airflow (such as carpeting).

If your AVP becomes too warm, it will display an on screen message to that effect. If the temperature continues to rise, the unit will eventually protect itself by shutting itself off. This eventuality is extremely unlikely unless its surrounding ambient temperature is uncomfortably hot for people (as well as for electronics). An internal, temperature-controlled cooling fan kit may be ordered from Madrigal

if you do see the on screen warnings about excessive temperatures, and if improving the available ventilation in the installation would be difficult. Contact your dealer or distributor for more information.

Drawings are included in this manual to facilitate special installations and custom cabinetry (see Dimensions). An optional, purpose-designed rack mount kit is available for this product, drawings of which are also included at the end of this manual (see Rack Mount Kit).

The serial number for your Audio Video Preamplifier is found on the bottom of the unit. Please note and record this number for your future reference.

register your purchase! Having found the serial number, now would be a good time to fill out the regis-

tration card. Please register your purchase so we can advise you of software updates and other items of interest.

In the U.S. and Canada, registering your purchase also automatically extends your warranty from 90 days to five years. It will take only a minute

or so. Please complete the card now, before you forget.

Operating Voltage & Frequency

The Audio Video Preamplifier is set at the factory (internally) for 100V, 120V, 220V, 230V, or 240V and either 50 or 60 Hz 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.) Neither the voltage nor the line frequency setting may be changed by the user.

Make sure that the label on the rear panel of the Audio Video Preamplifier (above the AC input receptacle) indicates the correct AC operating voltage for your location. Attempting to operate the Audio Video Preamplifier at an incorrect voltage can damage the unit.

Warning: Neither the voltage nor the line frequency settings of your

Audio Video Preamplifier may be changed by the user. There are no user-serviceable parts within the unit. Please refer any problems to an authorized Proceed service center.

If the AC mains voltage or frequency indicated on your Audio Video Preamplifier is incorrect, please contact your local, authorized Proceed dealer or distributor.

The Audio Video Preamplifier can easily be powered by a normal 15-ampere AC mains line. If other devices are also powered from the same AC line, their additional power consumption should be taken into account.

warm up/break-in period Although your Proceed Audio Video Preamplifier 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 AVP 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 extended 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 Audio Video Preamplifier’s sound quality is at its best. Unless your Audio Video Preamplifier was allowed to become quite chilled, subsequent thermal re-stabilization should not take long.

A Word About Installation

Every effort has been made to make the Proceed AVP simple and straightforward to install and use. We know of no other product which offers this level of performance and flexibility (other than the more costly Proceed PDSD system).

Still, we have no way to evaluate many other variables such as the size and shape of your room, its acoustics, and the associated equipment you have chosen to use with your AVP. All of these factors influence the ultimate performance of your system. Moreover, the AVP incorporates many system-specific adjustments which enhance its performance with the widest possible range of associated components.

For this reason, we strongly encourage you to have your system installed and calibrated by your dealer, whose experience, training, and specialized equipment can make a profound difference in the final performance of the system.

The AVP features the ability to “remember” the carefully calibrated settings chosen by your installer. You may adjust any or all of these settings to suit your taste for a particular recording, either from the front panel or from the remote control. When you want to return to the calibrated settings (which most accurately reproduce the widest variety of program material), simply press recall on the remote control or on the front panel.

The Quickest Start: CD & DVD

The AVP is an exciting system, and we understand that many owners will be anxious to get it up and running as quickly as possible. What follows is not a r e- placement for a c omplete setup of the system. Rather, it is provided so you can get some music and movies playing as quickly as possible. It assumes that your system is already set up in other respects (speakers connected to power amps, etc.). Once done, please read up on how to do a complete setup and cali- bration in order to get the most from your investment (or have your dealer/installer do it for you).

We have shipped the AVP with two input buttons already pre-programmed for the sources most likely to be found in an AVP-based system: CD and DVD. Having done this, all you have to do is hook them up to the right connectors and press the button to get going.

This “quickest start” assumes that your CD transport has an AES/EBU output, and that your DVD player has both composite video output and a coaxial (RCA) digital output. If not, proceed to the next sections, A Quick Start For CD and A Quick Start For DVD.

1 MAKE THE PHYSICAL CONNECTIONS; TURN EVERYTHING ON

Connect the outputs of the AVP to your power amplifier(s), as indicated (front, rear, center, sub); ensure that the main video output of the AVP is connected to your television (so you can see the on screen menus). Once this is done, turn on all the components involved (CD transport, AVP, television, amplifiers). Turn the amps on last—always a good habit with any audio system.

2 CONNECT YOUR CD TRANSPORT TO THE AES/EBU INPUT ON THE AVP

Doing so will give you access to your CD transport via the CD button on the AVP.

3 CONNECT AN S/PDIF (RCA/COAXIAL) AUDIO OUTPUT FROM YOUR

DVD PLAYER, AND CONNECT THE COMPOSITE OUTPUT OF YOUR DVD PLAYER TO THE “COMPOSITE 1” VIDEO INPUT ON THE AVP

You might also take the time to set the digital output of your DVD player to “AC-3” instead of “PCM/Pro Logic.” It will still output PCM digital audio if you play a CD, but setting it to “AC-3” allows it to give you the discrete multichannel digital AC-3 standard. The AVP will automatically sense the nature of the signal it receives, and will switch accordingly.

We chose the composite output for the initial default simply because it is the output on DVD players that you can always depend on. (Many DVD

players have a switch that chooses between either S-video or component—if the switch happens to be in the wrong position, you would end up with no picture at all.)

4 PRESS EITHER CD OR DISC 1 AND START ENJOYING YOUR AVP

A Quick Start For CD

There is a reasonable chance that either your CD transport or your DVD player may have a different set of output connectors than what we have assumed it might have in the “quickest start” section. In that case, setting up the AVP to take advantage of your particular equipment is still quite simple, though it will require a couple extra steps.

1 MAKE THE PHYSICAL CONNECTIONS; TURN EVERYTHING ON

Connect the outputs of the AVP to your power amplifier(s), as indicated (front, rear, center, sub); connect a CD transport to any matching digital input connector on the AVP, noting which connector you use; ensure that the main video output of the AVP is connected to your television (so you can see the on screen menus). Once this is done, turn on all the components involved (CD transport, AVP, television, amplifiers). Turn the amps on last (always a good habit with any audio system).

2 PRESS AND HOLD THE CD BUTTON ON THE FRONT OF THE AVP

This shortcut of pressing and holding an input button will take you directly to the define button menu for that button.

3 TELL THE AVP WHICH CONNECTOR YOU USED FOR YOUR CD

TRANSPORT IN STEP 1

We have no way of knowing what sort of digital interface your particular CD transport might use (AES/EBU? RCA? BNC? EIA-J?), but logically, you’d like to be able to use your main CD transport with the button labeled cd. This step allows you to use whatever connector you need to use in conjunction with the button you’d like to use. Using the volume ± button on the remote (or the volume knob), move the arrow cursor down to the line that reads “audio connectors” and press enter (or mute on the front panel). Press

volume – to move to 1: Digital 1 and press enter (mute) again. Then move

the arrow cursor down to the line that defines which connector is being used, and press enter (mute) again. With the cursor changed to an arrow within a diamond (→ ) instead of an arrow, the volume ± buttons or the knob will allow you to select whatever digital input connector you used in Step 1. When done, press enter (mute) again to save your change.

4 PRESS MENU THREE TIMES TO EXIT THE MENU SYSTEM, AND ENJOY

Make sure the volume is on at a low level before you fire up your CD player, press the cd button, and raise the volume to a comfortable level. According to the factory defaults (which you can easily change), cd is preset to come on in 2-channel/surround off. You should properly calibrate the system so all speakers are playing at the proper volumes before you listen critically to multichannel audio. Performing this calibration only takes only a few more minutes, but you should read up on it a bit first. You can enjoy the AVP in regular stereo until then.

A Quick Start For DVD

We understand: you’re in a rush to hear Dolby Digital on your new system. Remember: What follows is not a r eplacemen t for a c omplete setup of the system. We will assume here that you have already done the CD setup on the previous page. To get a DVD player playing:

1 MAKE THE PHYSICAL CONNECTIONS

Noting which connectors you use, connect a digital output of your DVD to any matching digital input on the AVP, and a video output of your DVD to a corresponding video input on the AVP. Turn everything on.

2 PRESS AND HOLD THE DISC BUTTON ON THE AVP

This shortcut of pressing and holding an input button will take you directly to the Define Button menu for that button, disc in this case .

3 TELL THE SYSTEM WHICH CONNECTORS YOU USED FOR YOUR DVD

PLAYER IN STEP 1

Using the volume ± buttons (or the volume knob), move the arrow cursor down to the line that defines your video connection and press enter (or

mute on the front panel). Make sure the AVP knows where you plugged in

your laserdisc player’s video output. Change the video: setting to the cor- rect video input, and press enter to save any changes you need to make.

Similarly, set up your audio connection: move the arrow cursor down (vol-

ume ±

) to the audio connectors line and press enter; move to the line that reads 1: digital 2, and press enter again. Move down to the connector line, press enter and with the cursor changed to an arrow within a diamond ( ), the volume ± buttons will allow you to select whatever digital input you used when hooking up the system.

4 PRESS MENU A FEW TIMES TO EXIT THE MENU SYSTEM, AND ENJOY

Make sure the volume is on at a low level before you fire up your DVD player; press the disc button once, and raise the volume to a moderate/ comfortable level. Importan t: you should properly calibrate the system so

all speakers are playing at the proper volumes before you listen critically to multichannel audio. Performing this calibration only takes only a few more

minutes, but you should read up on it first. Please review the chapter on The Setup Menu for more information, pp. 42-58.

Special Design Features

Congratulations on your purchase of the Proceed Audio Video Preamplifier (AVP). We have gone to great lengths to ensure that the AVP remains “future-proof” even in these times of change. As a result, you will be able to enjoy the outstanding performance of the Audio Video Preamplifier 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 product.

powerful hardware The AVP shares the same type of powerful DSP engine used in the Proceed Digi-

tal Surround Decoder, employing multiple Motorola 56303 DSP chips in a Madrigal-designed operating system. This DSP engine has sufficient power to handle the decoding requirements of Dolby Digital, DTS, MPEG2, HDCD, THX, and others. In addition, its power and flexibility provide for future updates to handle asyet-undefined digital audio standards that may be adopted in the future, such as the 24 bit/96 kHz high quality audio disc proposal for a DVD-audio (only) disc.

If a new, dedicated DVD-for-audio format is defined, it will almost certainly use significantly more “bandwidth” than today’s digital audio standards—after all, providing more information per second is the basis for the improvement in quality. Fortunately, the AVP includes a special, Madrigal-designed Digital Interface Receiver (DIR) that can receive digital information even faster than a dedicated DVD could send it, while at the same time rejecting timing errors called “jitter” in the digital signal. Thus, this Madrigal DIR protects the AVP from premature obsolescence (by allowing it to receive as yet undefined signals of up to 12 Mbits/sec), while improving the sound quality of every digital source connected to the product (by rejecting incoming jitter).

The AVP includes eight channels of digital to analog conversion, all of which can process and convert 96 kHz information. In addition, all volume controls within the AVP are implemented in the analog domain, allowing the DACs to run at their maximum resolution at all times. (This approach stands in contrast to digital vol-

ume controls, which operate by requiring the converters to operate at less than their maximum capabilities. After all, what would be the point of having 24 bit/96 kHz music formats if you end up throwing away much of the improvement in a digital volume control?)

software updatable All the software that the AVP uses is stored in special “flash” memory that can

easily be updated as improvements are made available. These improvements can affect both operational and performance enhancements.

With a simple software download a short time after such a standard is announced, your Audio Video Preamplifier would be able to both decode and play back the new audio standard, and flip back and forth between the different versions of the music on the disc for comparison purposes. For example. since the AVP was originally introduced, we have added DTS decoding, MPEG audio decoding and 8-channel support, all available to pre-existing units by simple software downloads.

The Audio Video Preamplifier is designed to avoid the premature obsolescence that will be the hallmark of far too many products sold in these changing times.

multichannel The Audio Video Preamplifier is designed to be flexible with respect to its audio

configurations, as well. In its standard configuration, it provides the standard 5.1 channel selection of outputs made popular by home theater. However, it also includes an extra two channels that may be used in any of several ways, whether to accommodate larger rooms (separate side and rear speakers) or more sophisticated audio processing (Dual Drive™ surrounds, for example). It is just a matter of what you want the system to do. That way, you can have the system the way you want it to work, rather than bieng limited to the way we thought you’d want it to work. (After all, a no-compromise, high performance audio system should not be “one size fits all.”)

audio computer Conventional audio DSP design requires the addition of costly hardware every

time you wish to add functionality. In these designs, Dolby Digital (AC-3) has its own, dedicated DSP chip and associated supporting circuitry; so does DTS; so does MPEG/Musicam. Want a new feature? Buy more hardware.

This strikes us as ridiculous.

You would not buy a computer for writing, knowing that you would have to buy another computer for calculations, and another for graphics, and a fourth for database work. To do so would be enormously wasteful, as expensive microprocessors would sit idly by while you were doing something else.

The same is true in “audio computers.”

The Proceed Audio Video Preamplifier is helping to define a new generation of powerful DSP (Digital Signal Processing) engines that can load software in and out of memory dynamically, as your computer does. Want to listen to a Dolby Digital soundtrack? The AVP loads the appropriate software and runs it. Movie over, want to listen to CD? No problem. Oh, the CD is DTS-encoded? Still no problem — the DTS software is loaded and runs on the same chip that had been running Dolby Digital a few moments ago.

Madrigal was an early partner of Motorola in developing the next generation of DSP chips, the 56300-series. Designed to replace the aging 5600X series, these new chips offer twice the performance and vastly more flexibility. With two such chips in each Audio Video Preamplifier, we have the power to run these programs as well as our own proprietary digital filtering algorithms.

Why did we develop such advanced technology? Simple: better performance for today, and for tomorrow.

Pressing this button places the AVP in standby mode, turning off the display, disengaging all control functions, and turning off all outputs to the main zone (remote zone functions are still available). The internal circuitry remains on in order to maximize performance on demand by virtue of all circuits remaining thermally stable. Lest you think this wasteful, you should know that the AVP draws about the same power as a light bulb, whether in

standby or fully on. The benefits of having it always warmed up and ready

to go (and always able to respond to remote control commands) far outweigh the small amount of power used. We recommend using the front panel power switch (13 ) only when you will be away from the house for extended period of time, such as during a vacation.

There is another good reason for using the AVP’s standby mode. The AVP will generate a full-frame, dark grey video signal during standby, rather than passing no signal at all. This is particularly helpful with many projections televisions, since it gives the projector a “sync” signal without calling for any significant generation of light. This feature allows the projector to remain fully warmed up at all times without risking damage to the phosphors which create the projected light.

2 AUDIO/VIDEO SOURCES

These five buttons select both the video and associated audio signals from any of the defined A/V inputs. (See define source buttons in The Setup Menu section of this manual.) To use these Selection Buttons, choose the appropriate path (see path, below). (For your music/home theater room, “main” would be appropriate.) Then make your selection. The sophisticated switching system employed in the AVP allows simultaneous, independent routing of both audio and video signals the two signal paths: main, and

remote/record.

3 AUDIO SOURCES

These four buttons select audio signals from among the defined audio-only inputs. (See define source buttons in The Setup Menu section of this manual.) To use these selection buttons, choose the appropriate path (see

path, below), and then make your selection.

Viewing Simulcasts Selecting any audio source after having selected a video source will cause

the newly-selected audio signal to “override” the audio portion of the video selection (leaving the video signal unaffected). Thus, to enjoy a simulcast, merely select the desired picture followed by the desired sound. To revert to the regularly-used sound of the video input, just press the video input button again.

4 “MORE” SOURCES

With five A/V sources and four audio source buttons, most people will find the AVP’s source selection capabilities more than adequate. However, the AVP provides a total of fifteen audio inputs (seven analog and eight digital), in order to accommodate differing connection standards that may be used on your source components. In addition, there are either six (composite version) or nine (S-video version) video inputs available for use. Rather than allowing these extra connectors to remain unused after the initial nine primary source buttons are defined, we have provided a more button to access additional, less frequently used sources.

To define additional sources that will be accessed by the more button, simply use the menu system to define “more” sources: either a/v or

audio-only. (See set more buttons in The Setup Menu section of this

manual.) You can teach a learning remote control a direct-access command for any of these “extra” sources, or use the more button to cycle through them.

5 PATH BUTTON AND INDICATORS

Pressing this button cycles among your various signal path options:

• main — the main room/home theater; this path determines

which video and audio sources are sent to the Main outputs on the back of the AVP. Sources selected for the main path are indicated in yellow on the front panel LEDs.

• remote — determines which video and audio sources are sent to

the Remote outputs on the back of the AVP, to be sent to another system elsewhere in the house. These sources are indicated in red on the front panel LEDs. The remote path may also be used as a secondary Record Output path if necessary.

• both — the audio and video signals for both main and remote

paths may be selected at the same time, for your convenience; as when entertaining, perhaps, for whole-house background music. Sources selected for “both” main and remote paths will be indicated by green LEDs.

• record — determines which video and audio sources are sent to

the various record output jacks. The source selected for the record path is indicated on the front panel in red LEDs. As a safety measure, the AVP can provide protection against the selection of any recordable device as its own source, to avoid feedback loops. The AVP can also display the words record loop on screen as a warning when you accidently begin to set up such a loop.

Tip: To avoid any possibility of running into a “Tape Loop” problem

(where the AVP prevents you from choosing what you want, in order to protect the system from possible damage), simply select a non-recording source on the record path.

6 SURROUND MODE

Pressing this button cycles among the various surround modes of the AVP:

• Home THX cinema — for movies which were mixed for theatrical

release; THX may be added to any multichannel mode associated with movies (Dolby Digital/AC-3, Dolby Pro Logic, DTS, MPEG).

• pro logic — manually selecting Pro Logic may be needed when

listening to a conventional (PCM) digital signal, as from a laserdisc player, which does not have an identifying “flag” to indicate whether it is simply stereo, or Dolby Surround encoded. (In the case of AC-3, DTS, or MPEG, the AVP will know positively what sort of decoding is required and will provide it automatically.)

• stereo surround — for enjoying two-channel stereo recordings

using all loudspeakers; this is an ambience extraction mode that uses the natural ambience in the recording itself, rather than synthesizing something artificial.

• mono surround — for monophonic recordings which would ben-

efit from some degree of additional ambience or spaciousness, such as many classic movies and some sporting events.

• 2-ch/surround off — limits the system to two-channel stereo.

• mono —a “true” mono, reproduced only through the center chan-

nel speaker and subwoofer. Noisy mono soundtracks often enjoy significant noise reduction by being reproduced in this mode.

7 DISPLAY INTENSITY

Pressing the display intensity button will cycle the AVP’s display through the four available levels of brightness: high, medium, low, and off. For example, during bright daytime hours you may wish to use high; in the evening, in a dimly-lit room, low is probably easier on the eyes.

8 RECALL

Pressing the recall button restores the AVP to its calibrated reference settings for the relative output of all speakers. This is especially helpful after having experimented with various settings of balance, center, rear, or sub, or when comparing a modified surround default to “flat” balance, since one touch of a button will restore your preamplifier to its original state (as determined by the setup calibrations stored in memory; see System Setup & Calibration and Using the AVP for more details).

9 MAIN DISPLAY

The main display provides information pertaining to the operation of the AVP including selected source, surround mode, and volume levels. At all volumes above a relatively quiet background level, and in all modes, the volume control enjoys a resolution of 0.5 dB. Thus a change of 9.5 decibels would be indicated by a change of 9.5 in the display.

The main display indicates the selected source and master volume by default, and can also display the following offsets when chosen: balance,

center, rear, sub. In addition, it can also display the input level (used in cali-

brating the input level to the analog to digital converter on analog sources only) and the rear channel delay (in milliseconds). Right- and Left-facing

arrows are provided to indicate the direction of the balance offset. Finally, the infrared receiver and transmitter for the remote control are positioned on the left side of the main display.

10 DELAY

Pressing this button allows you to adjust (using the volume knob) the de-

lay

introduced to the signal being sent to the surround/rear channels, in milliseconds (mS). This delay setting is in addition to the 15 msecs required by Dolby Pro Logic when in the Pro Logic mode.

11 INPUT LEVEL

Pressing this button adjusts the input level of the selected signal to the ana- log to digital converter. It may be used to compensate for variations in level among sources. This adjustment is only important for analog sources (since digital sources are effectively “level adjusted” when they were first converted to digital).

If overload should occur, the AVP will indicate it by displaying ADC

CLIPPING

in the main display and on the screen. Pressing the input level button followed by turning the volume knob counterclockwise will reduce the input level by the number of decibels shown in the main display. Do so until there is no indication of clipping, even during the loudest passages.

You can also create a different, default input level setting for each analog source defined in the menu system. If you can generate a 1 kHz, 0 dB reference signal in the source component (for example, a cassette tape recording of a 1 kHz test tone, with the recording meters showing 0 dB), use this signal to calibrate the input. With the volume of the AVP turned down, play the 0 dB test tone, and adjust the input level until the indicator light first turns on. Reduce the input level setting a few decibels to allow for peaks above 0 dB, and then press either the enter button on the remote or the

mute button on the front panel (which serves the same purpose when in

the menu system) to enter this default input level setting for the currently selected input. (You may repeat this procedure for each analog source.)

12 M U T E

Pressing the mute button will reduce the main output level of the preamplifier by a user-modifiable amount, ranging from 1 to 60 decibels . Pressing the mute button a second time without adjusting the volume will return it to its previous setting. If you adjust the volume with either the front panel buttons or the remote control while in the mute mode, the preamplifier will adjust its volume from the muted volume and disengage the mute function. The factory default setting of the mute circuit is -20 dB. (See Using the AVP for information on changing the factory default setting.)

13 POWER BUTTON AND INDICATOR

Assuming that the Audio Video Preamplifier’s power cord is connected to AC power, pressing this latching power button connects the AVP to the AC mains and turns on the unit. When power is restored after an interruption, the AVP will enter standby after a few moments’ delay to allow its circuits to stabilize.

If AC power is being supplied to the Audio Video Preamplifier, the LED above the power button is amber. Naturally, when AC power is discon- nected, the LED is off.

14 MASTER

Normally, any adjustment made with the volume knob will be applied to all loudspeakers equally, including Center, Rears, and Subwoofer(s), thus raising or lowering the overall volume without changing the relative balance of the various speakers. This is the default mode of operation for the volume control, to which the AVP automatically returns after you make other adjustments (after a brief delay).

If you have changed the relative volume by adjusting balance, center, rear, or subs, and wish to return more quickly to the normal master volume control, pressing this button will override the usual delay and return you immediately to master volume control operation.

15 BALANCE

Pressing this button followed by adjusting the volume knob will alter the relative volume of the Front Left and Front Right speakers. The direction of the perceived image shift is indicated by the arrowhead indicators in the main display, as well as by the on screen display. When the balance in “centered” (favoring neither side over the other), the display will read

< –␣ – EVEN – – >.

Turning the knob clockwise in the balance mode will shift the image to the right; turning the knob counterclockwise will shift the image to the left.

16 C EN TE R

Pressing this button followed by adjusting the volume knob (or volume ± on the remote control) will alter the volume of the Center speaker relative to its normal, calibrated setting. The resulting offset will be indicated in the

main display, as well as by the on screen display, until the volume control

reverts to its normal, master mode. As an example, increasing the center channel volume by three decibels would result in a +3.0 being displayed until the volume control reverted to normal operation, at which point the display would again indicate the overall volume setting.

17 REAR

Pressing this button followed by adjusting the volume knob (or volume ± on the remote control) will alter the relative volume of the Rear speakers relative to all others. The resulting offset will be indicated in the main dis-

play

, as well as by the on screen display.

18 S UB

Pressing this button followed by adjusting the volume knob (or volume ± on the remote control) will alter the volume of the Subwoofer(s) relative to all other speakers. The resulting offset will be indicated in the main display, as well as by the on screen display, until the display returns to its normal,

master volume display.

19 VOLUME KNOB

This knob is used to make most adjustments on the AVP. While the volume

knob

normally controls the master volume of the music/home theater sys-

tem (main path), it can be used in concert with other buttons to control almost any aspect of system performance (as indicated above), and when navigating the menu system from the front panel.

Rear Panel

Please remember to make a note of what sources you connect to which inputs. You will need to set up the relationships between front panel buttons and rear panel connectors later, in the setup menu.

For now, you can connect any source to any compatible connector—just keep a list of what-goes-where. (Just such a list is waiting for you later in this manual. You might want to copy it in order to keep the original clean for future use.)

Caution! Disconnect all associated equipment from the AC mains

BEFORE making any signal connections and applying power to the Audio Video Preamplifier.

1 BALANCED ANALOG INPUT 1

This input accepts right-channel and left-channel signals from source equipment with balanced outputs.

The pin assignments of these XLR-type female input connectors are:

PUSH

Pin 1: Signal ground Pin 2: Signal + (non-inverting) Pin 3: Signal – (inverting) Connector ground lug: chassis ground

These pin assignments are consistent with the standards adopted by the Audio Engineering Society. Refer to the operating manuals of your balanced-output line-level sources to verify that the pin assignments of their output connectors correspond to the AVP. If not, wire the cables so that the appropriate output pin connects to the equivalent input pin.

Connect the right-channel and left-channel balanced outputs of your source components to the corresponding balanced inputs on the AVP.

Note: If you do not have balanced sources and need another single-

ended input, it is possible to fabricate a cable to connect linelevel sources with single-ended output to these balanced inputs:

22-gauge

bus wire

Male RCA

(connect to source)

Male XLR

(connect to AVP)

2 SINGLE-ENDED ANALOG INPUTS 2-8

These inputs accept right-channel and left-channel audio signals from source equipment with single-ended (RCA) outputs. Single-ended audio inputs are provided for a total of seven components. Note that the video portion of the signal from any video source (VCR, laserdisc, TV) would be connected on the right side of the rear panel, in the Video Input section. (See below.)

Connect the right-channel and left-channel single-ended outputs of your various source components to the corresponding inputs on the AVP.

3 AES/EBU DIGITAL INPUT 1

Digital Input 1 accepts digital audio in the professional 110Ω AES/EBU digital

interface standard (via a cable equipped with XLR-type connectors) from a digital satellite receiver, compact disc, laserdisc, DVD or other digital source component. Connect the AES/EBU digital output of your source component to the AES/EBU input of the AVP using a high quality 110Ω AES/EBU cable such as Madrigal MDC-1.

The pin assignments of these AES/EBU XLR-type female input connectors are:

PUSH

Pin 1: Shield Pin 2: Digital + (non-inverting) Pin 3: Digital – (inverting) Connector ground lug: chassis ground

These pin assignments are consistent with the standards adopted by the Audio Engineering Society and the European Broadcast Union. Refer to the

operating manuals of your digital sources to verify that the pin assignments of their output connectors correspond to the Audio Video Preamplifier. If not, wire the cables so that the appropriate output pin connects to the equivalent input pin.

4 S/PDIF (ON RCA) DIGITAL INPUTS 2-5

Digital Inputs 2-5 accept digital audio conforming to the 75Ω S/PDIF digital

interface standard (via 75Ω cables equipped with RCA-type connectors) from a digital satellite receiver, compact disc, laserdisc, DVD or other digital source component. Connect the 75Ω S/PDIF output of your source compo- nent to either of this input of the AVP, using a high quality 75Ω cable such as Madrigal MDC-2.

If you have the optional internal RF demodulator installed in your Audio Video Preamplifier, Digital Input 3 is dedicated to that RF connection and can only be used for that purpose. Connect the RF (Dolby Digital/AC-3) output from your laserdisc player to Digital Input 3 if you have the internal RF demodulator installed.

5 S/PDIF (ON BNC) DIGITAL INPUT 6

Digital Input 6 accepts digital audio conforming to the 75Ω S/PDIF digital in-

terface standard (via 75Ω cables equipped with BNC-type connectors) from a digital satellite receiver, compact disc, laserdisc, DVD or other digital source component. Connect the 75Ω S/PDIF output of your source compo- nent to either of these inputs of the Audio Video Preamplifier, using a high quality 75Ω cable such as Madrigal MDC-2.

6 EIAJ OPTICAL DIGITAL INPUT 7

Digital Input 7 accepts digital audio in the EIAJ optical (sometimes called

“Toslink”) digital interface standard from a digital satellite receiver, compact disc, laserdisc, DVD or other digital source component. Connect the eiaj digital output of your source component to the EIAJ input of the Audio Video Preamplifier using a high quality EIAJ optical cable.

7 VIDEO INPUTS

Two different video configurations exist for the AVP: composite video only and both S-video and composite video. The composite-only version includes six composite inputs, while the S-video version includes four composite and four S-video inputs for a total of eight. Any combination of the available inputs may be used, and for your convenience, conversion from Svideo to composite is provided on both the main and the record/remote paths. Thus S-video sources may be viewed via either the S-video or the composite outputs; composite sources are only available on the composite output.

Composite video inputs use RCA connectors. S-video inputs utilize “S” connectors:

S-video connector

Connect the video outputs of your video components to appropriate video inputs on the AVP. (See The Setup Menu for more information on program- ming your input buttons for either composite or S-video use.)

Installation Note: S-video (Y/C) signals are more susceptible to degradation

over long wire runs. The quality of wire used makes a significant difference, but regardless, it is generally inadvisable to run S-video cables more than twenty feet (6 meters). Composite video signals tend to hold up better over longer runs, especially when high quality 75Ω cable such as Madrigal MDC-2 is used.

8 BALANCED MAIN OUTPUTS (L, C, R)

The pin assignments of these XLR-type male outputs conform to the international AES standard, and are as follows:

Pin 1: Signal ground

Pin 2: Signal + (non-inverting) Pin 3: Signal – (inverting) Connector ground lug: chassis ground

Refer to your power amplifier’s operating manual to verify that the pin assignments of its input connectors correspond to the Audio Video Preamplifier. If not, wire the cable so that the appropriate output pin connects to the equivalent input pin, or reverse the leads of both your speaker cables to “reverse the reversal” and restore correct polarity.

High quality single-ended outputs are also provided for compatibility with power amplifiers lacking balanced inputs.

Connect the left-front, center and right-front outputs of the Audio Video Preamplifier to the corresponding inputs on your power amplifier(s).

9 SINGLE-ENDED MAIN OUTPUTS (ALL CHANNELS)

The first six of these eight RCA connectors provide the main 5.1 channels normally associated with a high quality multichannel system: the left-front,

center and right-front outputs of the AVP are duplicated here in single-

ended form (for compatibility with power amplifiers lacking any balanced input capabilities), along with the left-surround, right-surround and

subwoofer channels. Connect these outputs to the corresponding power

amplifier channels.

In addition, two “auxiliary” output channels are provided, labelled aux 1 and aux 2. These channels are reserved for future use, for applications such as separate side and rear channels, or to provide left-center and right-center outputs for the MPEG 7.1 format used in Europe, or as additional subwoofer channels (front and rear, left and right, or common-mode). The AVP’s hardware has been designed to support such functions to meet future needs that may arise with the rapidly-changing world of multichannel audio formats. Stay in touch with your dealer or check our web site periodically (www.madrigal.com) to stay informed as to software developments that would take advantage of this hardware.

10 REMOTE ZONE OUTPUTS

The AVP includes a second signal path (beyond the primary one used in the main listening room) that can feed a remote zone, or a record path for making recordings, or both. There is one limitation: the remote and record outputs always contain the same signal.

Thus you can watch one program while recording another; or watch one program while sending a different one to another part of the house; or you can watch what is being recorded from either another part of the house or from within the main room. But there is a limit: you cannot have three in- dependent programs running simultaneously on the main, remote and

record paths, because the remote and record paths always share a single

source.

controlling remote

zone volume

The main difference between the remote output and the record outputs is that the remote outputs include a high quality analog volume control; the

record path remains at a fixed, line level at all times.

The AVP can distribute either analog or digital sources to a remote zone or recording devices without your having to think about the details of whether the signal originates from an analog or a digital source.

The volume of the remote zone is controlled by selecting the remote path on the front panel and then adjusting volume conventionally, using the knob; alternatively, it may be adjusted by simply sending an infrared volume command to the rear panel ir input, when that input is configured to receive only re-

mote

zone signals.

If you are using a remote zone, connect either the balanced (preferred, especially for long runs of cable) or the single-ended remote outputs to the ampli- fier serving your remote zone.

11 RECORD OUTPUTS

record paths, because the remote and record paths always share a single

source.

The main difference between the remote output and the record outputs is that the remote outputs include a high quality analog volume control; the

record path remains at a fixed, line level at all times.

If you wish to make recordings to a recording device such as a cassette deck or VCR, connect the record outputs to the record inputs of that device. Be sure to tell the AVP that the device is capable of recording in the define

buttons

menu, within the setup menu, during initial setup of the system. (See

The Setup Menu.)

12 DIGITAL OUTPUT

The (S/PDIF on an RCA) digital output allows you to distribute a digital source in its original, unprocessed digital form. For example, if you had another multichannel system elsewhere in the home, you could forward a Dolby Digital bitstream to the other system from this one—running a single digital cable instead of five or six analog cables for surround sound applications.

Alternatively, you could use this digital output to make digital recordings. Note that this output will not contravene any copy protection systems, and you should only make copies of recordings for which you have legal rights to do so. (You always read the FBI warning at the beginning of movies, right?)

The digital output always tracks whatever source is selected in on the main

path

(as opposed to the remote/record path).

13 PHASTLink™ CONTROL PORTS

These two communications ports provide for sophisticated inter-component communications between the AVP and certain compatible Proceed products. To access the built-in intelligence of these communications capabilities, simply “daisy chain” your various PHAST™-capable Proceed components together using eight conductor “straight-through” cables with RJ-45 connectors at both ends. You can buy these cables from your dealer as an accessory item.

Thus, if the only other Proceed PHAST-compatible component you have is the Five Channel Amplifier, you should connect the AVP’s comm out port to the power amplifier’s comm in port using a “straight-through” RJ-45 cable. If there are additional Proceed PHAST-compatible components in the system, daisy chain them in a similar way, always going from comm out to comm

The RJ-45 cable needed for the connection between the AVP and other PHAST-compatible Proceed components may be purchased from your Proceed dealer. It may also be easily and inexpensively made to length using two RJ-45 connectors and the appropriate length (up to 100 feet/30 meters) of RJ-45 (flat, eight conductor) cable.

RJ-45 cables and connectors are used throughout the world for both telecommunications and computers, and are widely available at low cost. The connectors are crimped on to the ends of the cable such that pin 1 at one end is connected to pin 1 at the other end. Such a “straight-through” connection is (counter-intuitively) made by introducing a 180° twist in the cable between the two ends, as shown below.

Connecting the communication ports other than as described in this manual may damage the AVP and the associated components, and will void those products’ warranties.

These ports also provide for extensive home automation flexibility via the PHAST™ protocols, should you be interested in integrating other brands of products into the system in a more comprehensive control system. Your dealer can assist you in taking advantage of these advanced features.

14 RS-232 PORT

The AVP also includes an RS-232 port, which may be used in conjunction with external control systems such as Audioaccess, AMX, or Crestron. Your dealer can assist you in taking advantage of these advanced features.

This RS-232 port may also be used to update the operating software of the AV P, so that your system will be able to handle new digital audio formats as they are introduced. (Think of updating the software in the AVP as being like installing new software in your computer… only much less painful.) Once again, your dealer can assist you in taking advantage of these advanced features, should the need arise.

The “pinout” connections used on the RJ-11 connector used for the RS-232 port is as follows:

Note that only qualified technicians should attempt to make use of the special capabilities afforded by this communications port.

15 IR INPUT

A 1⁄8" “mini” jack labeled ir input near the lower right corner of the rear panel provides direct access to the infrared control circuitry of the AVP. It may be configured during setup (in an on screen menu) to interpret incoming signals in either of two ways:

• Remote: when in Remote mode, the AVP will interpret any com-

mand entering through the remote IR jack as being intended to affect the record/remote path only. This feature allows easy ac- cess to all sources connected to the AVP from elsewhere in the house with the addition of any commercially-available IR repeater.

• Local: when in the Local mode the remote IR jack replaces the

infrared receiver in the main display of the front panel. This mode is most often used with an IR repeater when the AVP and other components are placed inside of cabinets (preventing the normal IR receiver from receiving remote commands). Setting the remote IR jack to local will disable the IR receiver in the main display to avoid inconsistent operation which might be caused by interference between the two incoming signals, should the door to the cabinet be opened. (See The Setup Menu.)

IR input tip polarity

The incoming signal for the remote IR input should conform to widely-accepted IR repeater standards: that is, the signal present should be between 3-15 volts DC at less than 100 mA current, with a positive tip polarity, as shown below:

+–

5-12 volts @ less than 100 mA

Your Proceed dealer can help you take advantage of these design features to maximize your system’s versatility.

16 DC TRIGGERS

Each of the two remote on/off triggers can be configured by your installer to provide either 5V or 12V DC trigger signals, either in response to the AVP coming out of standby into operate, or in response to an independent IR

command

. The tip polarity for each of these triggers is as shown below:
