Maximizing the Value

of Your Purchase

Congratulations on choosing a superb product. Your Proceed PAV is designed to give you many years of outstanding performance, and we are confident you will be happy with it.

We value our relationship with our customers, and often are in a position to help you enjoy your home entertainment system even more—if we have some way of contacting you.

Send in that warranty card! Sending in your warranty card registers your product with us so that warranty service in the U.S. and Canada (see the warranty policy on page 75) can be obtained easily and quickly even if you have lost your original sales slip. (And how many of us are organized enough to retain all those sales slips?) Moreover, sending in the card automatically extends the warranty from 90 days to five years, at no cost to you. Please send it in soon, before you forget.

But there are even more benefits to sending in your registration card, including services for people outside the U.S. and Canada.

software update notices

performance upgrade notices

free subscription to Madrigal’s QuarterNotes newsletter

We have occasionally offered software updates to our products that provide new features and control options (for example, to facilitate their inclusion in custom installations, or that automate customer preferences to greater degrees than previous software versions). These updates are generally a matter of changing out a socketed EPROM. If they include features you would like to have, you can get them—if you know about them.

We also try to offer performance upgrades and/or conversions to make upgrading within a family of products as cost-effective as possible for our customers. For example, people who already owned the Proceed DAP digital processor when the HDCD process became available were able to upgrade their unit to HDCD™ for an extremely nominal price. While not all upgrades can be inexpensive, they all represent excellent values—if you know about them.

One of the best ways we have of communicating with the large number of customers we have around the world is through our company newsletter, QuarterNotes. This newsletter contains information on industry developments, new products, software updates and upgrades, as well as general interest articles on recommended music and movies, and occasional profiles of customers and industry personalities. QuarterNotes is a service we provide to help keep open our lines of communication with our customers, and it is free—if we know where to send them.

So please, take a few minutes to fill out the warranty registration card, and drop it in the mail.

Unpacking and Placement

Unpacking Unpack your Proceed® PAV audio video preamplifier and keep all packing materials for future transport. Locate and remove all accessory items from the cartons. Accessories include:

1AC power cord

1PAV remote control

4 alkaline batteries for the remote control

Important!	Your PAV has been shipped with software pre-installed that
	enables it to work seamlessly with a Proceed PDSD as part of
	a high performance, two-piece multichannel controller. If you
	need to use the PAV by itself (without a PDSD), your dealer
	must install the enclosed EPROM found in a small black anti-
	static box. Do not attempt to install this yourself, as only
	qualified technicians may open the unit without voiding the
	warranty!
Installing Batteries in
Installing Batteries in	Turn the remote control over and slide the battery compartment cover up and
the Remote Control	away from the body of the remote. Insert the four alkaline batteries found in the
	Accessories kit, being careful to follow the polarity indications given on the inside
	of the battery compartment. Replace the battery cover.
Placement	Place the PAV near the source equipment, thus keeping interconnecting cables
	reasonably short. It may be placed on a shelf or in a cabinet where it’s conve-
	nient to operate.
	Note that adequate clearance for the AC cord and connecting
	cables must be left behind the PAV. We suggest leaving at least
	three inches of free space behind the PAV to allow all cables
	sufficient room to bend without crimping or undue strain.
Ventilation	It is normal for your PAV to run quite warm. Be sure to allow 2 to 3 inches of
	clearance above the PAV to allow heat dissipation through air circulation. The
	vents on both the bottom and the top of the PAV must be kept free from any ob-
	struction which would reduce the flow of air through the unit. The best rule of
	thumb is this: if the top of your PAV is too hot to touch, it needs better ventila-
	tion. If so, consider drilling holes in the supporting shelf under the PAV to pro-
	mote flow-through ventilation, or use fans to increase air circulation. Avoid place-
	ment on soft surfaces that would restrict airflow (such as carpeting).
	Mechanical drawings are included in this manual to facilitate special installations
	and custom cabinet work (see “Dimensions” at the end of this manual).

Operating Voltage

The PAV preamplifier is factory-set for 100V, 120V, 200V, 220V, or 240V AC mains operation at either 50 or 60Hz, according to the country for which the unit was manufactured. (230V only in European Union countries, in compliance with CE regulations.) Make sure that the label on the bottom of the PAV 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 does not match what is supplied to your area, see your Proceed dealer.

A Word About Installation

Every effort has been made to make the Proceed PAV simple and straightforward to install and use. We also know of no other product which offers this level of performance and flexibility. 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 PAV. All of these factors influence the ultimate performance of your system. Moreover, the PAV 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 PAV 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.

Movie Sound and the PAV

Home Theater and

the Proceed PAV

Perhaps the most exciting development in home entertainment in recent years is the much-discussed “marriage of audio and video.” Movies are available in high quality formats such as laserdisc, and big-screen televisions have improved vastly over the dim, fuzzy pictures many people remember from a few years ago. Combined with sound reproduced via several loudspeakers and (perhaps) a subwoofer, it has become possible to have movie excitement in the home which far exceeds that available in most local theaters.

Unfortunately, many people found these “home theaters” sadly lacking when it came to their performance with more traditional music sources. Although some were capable of shaking the walls with explosions and sound effects, few were capable of reproducing the nuances of a string quartet, a big band, or a well-re- corded vocalist.

The Proceed PAV is designed for people (like ourselves) who desire to “have it all.” The PAV offers the musical refinement, control flexibility and movie excitement of both a dedicated high end music system and a full-blown home theater system, all in one simple package. With its introduction, there is no longer a need to compromise on either music or movies. A single system can do it all.

			Listening Room

Unlike traditional stereo sources, Dolby Stereo™ movie soundtracks contain four channels: Left, Center, Right and Surround. The three speakers in the front of the room (L, C, and R) provide precise localization of sounds, or imaging, while the surround channel is intended to be reproduced in a diffuse manner to the sides and behind the audience—to literally “surround” that person in the ambient sounds of the environment shown on the screen. Normally, a correctly operating Surround channel would be so diffuse and enveloping as to be almost subliminal. Its purpose, after all, is to draw you into the movie, not to distract you from it.

Dolby Pro Logic™ Sources The PAV accurately decodes the Dolby Stereo™ soundtracks available in virtually all modern film soundtracks, many television shows, and even some music recordings. It does so by employing carefully optimized Dolby Pro Logic circuitry, for superior performance and accuracy. Use the pro logic mode whenever listening to most surround-encoded television shows, MTV (most of which is now surround encoded), and other surround-encoded program material which has been created for general distribution.

THX Cinema Sources In addition, the PAV incorporates Home THX® audio processing to help movie soundtracks make the transition from large movie theaters into the home. This extra step is necessary because the acoustics of movie theaters and living rooms are so different. Some adjustments are necessary in order to achieve the same subjective effect in your home as in the finest movie auditoriums. These “adjustments” are precisely what Home THX offers. Use the THX cinema mode for Dolby Stereo movies which were created for theatrical release—meaning virtually all movies made since the late 1970’s.

Music and the PAV When it is time to enjoy some of your favorite music, the PAV gives you several simple options, any of which may be selected by pressing the mode button to cycle through the choices.

The stereo surround mode uses ambient cues contained in your normal stereo recordings to create a realistic, full-bodied soundfield using all available speakers. It has been carefully tuned to enhance stereo playback, and can be expected to be relatively subtle rather than dramatic. (As with attending a live concert, one’s attention should rarely be called to the characteristic sound of the “hall.” The acoustics of the space in which the music is performed should enhance the musical experience without becoming an end unto themselves.)

The mono surround mode can be used to give acoustically “dry” mono recordings a sense of spaciousness. This mode can be used for historical monophonic music recordings as well as for older movie classics which were recorded in mono. This mode is particularly helpful when watching older, mono movies on a big-screen television, where the disparity between aural and the visual size would otherwise be a distraction to the movie experience.

The surround off mode returns your system to two-channel stereo.

Finally, we have provided a “true mono” mode which reproduces both the Left and the Right signals through the center channel speaker (and subwoofer) only. The mono mode is sometimes desirable when listening to noisy monophonic music recordings or movie soundtracks. Since noise tends to be random in nature, much of it cancels out when L+R are mixed together, as they are in this mode.

Subwoofers and If a subwoofer is connected to the sub outputs, it will normally be given the Surround Modes deepest bass (below 80 Hz) at all times, independantly of the surround mode or

input selected. Whether or not the three front speakers are also given the deepest bass information (below 80 Hz) to reproduce is determined by the settings of the set speakers menu during setup. (See System Setup & Calibration for more information).

1VIDEO SOURCE SELECTION BUTTONS

These four buttons select both the video and associated audio signals from any of the four A/V inputs. 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 PAV allows simultaneous, independent routing of both audio and video signals along any or all of three paths: main, remote and record.

2AUDIO SOURCE SELECTION BUTTONS

These six buttons select audio signals from among the six audio-only inputs. (Note that both cd1 and bal/aux are balanced inputs which use precision XLR connectors.) 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 sound of the video input, just press the video input button again.

3MAIN DISPLAY

The main display provides information pertaining to the operation of the PAV including relative volume levels, and is used in conjunction with the buttons which surround it. 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 10 decibels would be indicated by a change of 20 in the display.

The main display indicates the master volume by default, or the following offsets when chosen: balance, center, rear, subwoofer. In addition, it can also display the input level (used in calibrating the Dolby Pro Logic circuitry to the source material) and the rear channel delay (in milliseconds). Rightand 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.

4VOLUME +/–

These up/down buttons are used to make adjustments on the PAV, apart from source and path selection. While the volume +/– buttons normally control the master volume of the music/home theater system (main path), they can be used in concert with other buttons to control almost any aspect of system performance (as indicated below).

5MASTER

When the indicator above this button is lit, any adjustment made with the volume +/– buttons 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 PAV automatically returns after you make other adjustments.

6BALANCE

Pressing this button followed by the volume +/– buttons will alter the relative volume of the Front Left and Front Right speakers. The direction of the perceived image shift is indicated by the green arrowhead indicators in the main display, as well as by the on screen display. Pressing volume + in the balance mode will shift the image to the right (in a “positive” direction); pressing volume – will shift the image to the left (in a “negative” direction).

7CENTER

Pressing this button followed by the volume +/– buttons will alter the volume of the Center speaker relative to all others. 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 steps would result in a 3 being displayed until the volume control reverted to normal operation, at which point the display would again indicate the overall volume setting.

8REAR

Pressing this button followed by the volume +/– buttons will alter the relative volume of the Rear speakers relative to all others. The resulting offset will be indicated in the main display, as well as by the on screen display.

9MUTE

Pressing the mute button will reduce the main output level of the preamplifier by a user-modifiable amount, ranging from 2.5 to 55 decibels (5 to 110 in the main display). 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 (a change of 40 units in the Main Display). (See Using the PAV for information on changing the factory default setting.)

10SUB

Pressing this button followed by the volume adjustment buttons 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.

11REFERENCE LEVEL INDICATOR

This LED indicator is lit when the PAV is playing at Home THX reference level (normally calibrated during initial setup—see Output Level Calibration, p. 37).

12RECALL BUTTON

Pressing the recall button restores the PAV 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 PAV for more details).

13DELAY BUTTON

Pressing this button allows you to adjust (using the volume adjustment buttons) the delay introduced to the signal being sent to the rear channels, between 15 and 30 milliseconds (mS). (See Setting the Surround Delay, page 41, for more details.)

14INPUT LEVEL BUTTON & INDICATOR

Pressing this button adjusts the input level (or offset) on the main signal path. Together with the input level indicator in the main display immediately above it, it may be used to compensate for variations in level among sources. This adjustment is important primarily for movie sources (since Dolby Pro Logic circuitry is level-sensitive by its nature). When the Input Level is set correctly, the green indicator LED should be on most or all of the time during loud passages, but should never turn red (which would indicate an overload condition).

If overload should occur, pressing the input level button followed by the volume – button will reduce the input level. Do so until the indicator remains green during even the loudest passages.

Conversely, if you rarely see the green LED illuminate during loud passages, you should increase the Input Level to compensate for the relatively low level of the source. Press the input level button, followed by the volume + button to increase the input level.

15SURROUND MODE SELECTOR

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

•THX cinema — for movies which were mixed for theatrical release; both THX cinema and pro logic indicators are lit, confirming that Pro Logic is in use whenever the THX cinema mode is selected.

•pro logic — for all other surround-encoded material, such as many TV shows and some music recordings; only the pro logic indicator is lit.

•stereo surround — for enjoying two-channel stereo recordings using all loudspeakers; the stereo surround indicator is lit.

•mono surround — for monophonic recordings which would benefit from some degree of additional ambience or spaciousness, such as many classic movies and some sporting events; the mono surround indicator is lit.

•surround off — to return the system to two-channel stereo; the surround off indicator is lit.

•mono —a “true” mono, reproduced only through the center channel speaker and subwoofer. Noisy mono soundtracks often enjoy significant noise reduction by being reproduced in this mode; both mono and off indicators are lit to denote the fact that the surround circuitry is disengaged, leaving you with a “true” mono.

16PATH SELECTOR

Pressing this button cycles among your various signal path options:

•main — the home theater; this path determines which video and audio sources are sent to the Main outputs on the back of the PAV. Sources selected for the main path are indicated in yellow on the front panel LEDs. (If the LED blinks red, it is indicating a tape loop condition caused by the same source having been selected on the record path; deselect the source on the record path first, then reselect your main source.)

•remote — determines which video and audio sources are sent to the Remote outputs on the back of the PAV, to be sent to another system elsewhere in the house. These sources are indicated in green 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 yellow LEDs (the same as for the main signal path).

•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 PAV will prevent the selection of any recordable device as its own source (to avoid feedback loops). If such a selection is attempted, the PAV will cause the appropriate LED to

	flash yellow on the front panel, indicating a conflict on the
	main path. The PAV will also display the words tape loop on
	screen as a warning.

Tip:	To avoid any possibility of running into a “Tape Loop”
	problem (where the PAV prevents you from choosing what
	you want, in order to protect the system from possible
	damage), simply select a non-recording source such as TV
	on the record path.

17STANDBY BUTTON

Pressing this button places the PAV in standby mode, turning off the display, disengaging all control functions, and turning off all outputs. 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 PAV draws less than power than a typical 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 rear panel power switch 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 PAV’s standby mode. The PAV will generate a full-frame black video signal at its video outputs 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 to lock onto without calling for any light to be generated. This feature allows the projector to remain fully warmed up at all times without risking damage to the phosphors which create the projected light.

1SINGLE-ENDED AUDIO INPUTS (8)

Accepts 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 eight components, designated: vcr1, vcr2, tape1, tape2, a laserdisc player, your tv (or auxiliary component), a cd2, and a tuner. 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 PAV.

2BALANCED AUDIO INPUTS (2)

Accepts right-channel and left-channel signals from source equipment with balanced outputs. Provisions are made for two balanced signals via high quality XLR connectors, designated cd1 and bal/aux.

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

PUSH		Pin 1: Signal ground
2	1	Pin 2: Signal + (non-inverting)
		Pin 3: Signal – (inverting)
3

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 bal- anced-output line-level sources to verify that the pin assignments of their output connectors correspond to the PAV. 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 PAV.

Note: If you do not have balanced sources and need more singleended inputs, it is possible to fabricate a cable to connect linelevel sources with single-ended output to these balanced inputs:

3VIDEO INPUTS (4)

Four video inputs are provided in the PAV, designated: laserdisc, tv/aux, vcr1, and vcr2. These inputs may be configured for use with either composite or S-video (Y/C) signals during setup. Composite video inputs use RCA connectors. S-video inputs utilize “S” connectors:

S-video connector

The PAV does not provide for “cross-feeding” of S-video and composite signals. Any signal entering the PAV in either format will be output in the same format only. We strongly recommend standardizing on one or the other throughout the system for maximum ease of use. In addition, using both the composite and the S-video inputs simultaneously may result in a loss of video signal quality.

Connect the video outputs of your video components to the corresponding video inputs on the PAV. (See System Setup and Calibration for more information on programming these inputs 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 six or eight feet
	(2–2.5 meters). Composite video signals hold up better over
	longer runs, especially when high quality 75Ω cable such as
	Madrigal MDC-2 is used.

4AC POWER SWITCH AND AC POWER INPUT

An AC power switch is provided which disconnects the PAV from the wall outlet’s AC power. The PAV is designed to be left in Standby when not in use, rather than completely “off.” Being in Standby allows it to respond to commands from the remote control and maintains a stable operating temperature at all times for optimal performance and longevity.

Plug the supplied three-prong power cord into the AC Power Input recepticle provided before plugging the power cord into the wall. If a longer AC power cord is required for your application, be sure to use a three-conductor power cord which conforms to IEC standards.

The Proceed PAV has been safety-tested and is designed for operation with a three-conductor power cord. Do not defeat the “third pin” or earth ground of the AC power cord.

Beside the power switch you will find a communications port. This is reserved for future use (communicating with the PAV's companion piece, the Digital Surround Decoder). Do not insert anything into this port other than the communications cable from a “DSD.”

5REMOTE IR AND REMOTE TURN-ON

A 1⁄8" “mini” jack labeled remote ir. in the lower right corner of the rear panel provides direct access to the infrared control circuitry of the PAV. 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 PAV will interpret any command entering through the remote IR jack as being intended to affect the remote path only. This feature allows easy access to all sources connected to the PAV 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 PAV 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. (See Programming the IR Input, page 48.)

The incoming signal for the remote IR input should conform to widelyaccepted 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:

IR input tip polarity

– +

3-15 volts @ less than 100 mA

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

The remote turn-on output to the right of the remote ir input (as seen from the rear) can be used to toggle Proceed power amplifiers between standby and operate in concert with the operational status of the PAV. This output normally provides a 300 msec long, 8 volt positive pulse whenever the PAV turns on, and a 600 msec long, 8 volt positive pulse whenever the PAV turns off. (Alternatively, the PAV may be configured to provide a level control voltage that can be used by certain Niles controllers and similar products. See System Setup and Calibration for more information.)

To enable the PAV to control the turn-on and turn-off of the associated Proceed amplifiers, connect a wire terminated with a 1⁄8" “mini” plug at both ends (available in various lengths at electronics supply stores such as Radio Shack, or may be custom made to length by your installing dealer) between the remote turn-on output of the PAV and the remote turn-on input of the AMP. If more than one Proceed amplifier is being used, simple “Y-adapters” may be used to daisy-chain the turn-on signal for up to three AMPs’ turn-on inputs.

6VIDEO OUTPUTS

Four video outputs are provided in the PAV: main, remote, vcr1, and vcr2. S-video (Y/C) outputs utilize four-conductor “S” connectors, while the composite video outputs use RCA connectors.

The main output should be connected to your video monitor in the main home theater system. The remote output can be used to feed video signals to another system elsewhere in the house. The remaining vcr1 and vcr2 outputs are used for making recordings on those decks via the PAV, much as you would make audio cassette recordings with a traditional preamplifier or receiver. Connect them to the corresponding inputs on the back of those video tape recorders.

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 six or eight feet
	(2–2.5 meters). Composite video signals hold up better over
	longer runs, especially when high quality 75Ω cable such as
	Madrigal MDC-2 is used.

	The PAV does not provide for “cross-feeding” of S-video and composite sig-
	nals. Any signal entering the PAV in either format will be output in the same
	format only. For most people, it is simplest to standardize on one format or
	the other throughout the system. While it is possible to use a combination
	of both types of signal, this setup would require manual switching of in-
	puts on the video monitor whenever the monitored video source changed.
	In addition, using both the composite and the S-video outputs simulta-
	neously may result in a loss of video signal quality.

7REMOTE BALANCED OUTPUTS

If the system being used in the remote zone is equipped with balanced (sometimes called “differential”) inputs, it is best to use these balanced outputs on your PAV. A balanced signal from preamplifier to power amplifier will offer the highest possible performance with the best immunity from common-mode noise, such as electromagnetic interference (EMI) or radio frequency interference (RFI). This characteristic immunity is particularly important when using long cable runs, as may be expected when sending a signal to a remote location. The balanced output signal is made available by way of precision male XLR connectors (requiring female XLRs on the PAV end of the interconnecting cable).

The pin assignments of these XLR-type male outputs are:

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

Refer to your amplifier’s operating manual to verify that the pin assignments of its input connectors correspond to the PAV. If not, wire the cable so that the appropriate output pin connects to the equivalent input pin.

Connect the right-channel and left-channel balanced remote outputs of the PAV to the appropriate balanced inputs of the remote system.

8MAIN BALANCED OUTPUT

If the power amplifier being used to drive the Front Left and Front Right speakers is equipped with balanced (sometimes called “differential”) inputs, it is best to use the balanced main outputs on your PAV. A balanced signal from preamplifier to power amplifier will offer the highest possible performance with the best immunity from common-mode noise, such as radio frequency interference (RFI). The balanced output signal is made available by way of precision male XLR connectors (requiring female XLRs on the preamplifier end of the interconnecting cable).

The pin assignments of these XLR-type male outputs are:

	Pin 1: Signal ground
1 2	Pin 2: Signal + (non-inverting)
3	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 PAV. If not, wire the cable so that the appropriate output pin connects to the equivalent input pin.

Connect the right-channel and left-channel balanced main outputs of the PAV to the appropriate balanced inputs of the remote system.

9SINGLE-ENDED MAIN OUTPUTS

Single-ended (“unbalanced”) outputs are provided for compatibility with a wide range of associated components.

If you use the single-ended main outputs, connect them to the corresponding inputs of the amplifier being used to drive the Front Left and Front Right speakers.

10SINGLE-ENDED REMOTE OUTPUTS

Single-ended (“unbalanced”) outputs are provided for compatibility with a wide range of associated components, including power amplifiers and electronic crossovers.

If you use the single-ended remote outputs, connect them to the corresponding inputs of your remote amplifier (or other device).

11REAR SURROUND OUTPUTS (SINGLE-ENDED)

Connect these outputs to the input of the power amplifier being used to drive the surround speakers, which are normally located at the sides or the rear of the room.

12CENTER & SUBWOOFER OUTPUTS (SINGLE-ENDED)

The upper of these two RCA jacks should be connected to the amplifier channel which will drive your center channel speaker; the lower RCA jack should be connected to the amplifier channel which will drive your subwoofer(s).

If you have two channels of amplification driving multiple subwoofers, simply wire them in parallel from this output, using a Y-adapter. The output circuitry of the PAV can easily handle the extra amplifier without any loss of performance.

Please Note:	If your system does not have a subwoofer, leave the sub
	output empty. Also be sure the crossover is turned off during
	Setup in order to give your front loudspeakers a full-range
	signal. (See System Setup & Calibration for more details.)

13RECORD OUTPUTS (SINGLE-ENDED)

Four audio record outputs are provided, which are designed to work in concert with their corresponding inputs. For example, you would connect the vcr1 outputs to the audio input jacks on the video tape recorder you had connected to the vcr1 input. The record outputs are: vcr1, vcr2, tape1, tape2.

Learning Remote Control

This remote control uses four AAA 1.5V batteries. Please be sure to match the batteries with the (+) and (–) markings inside the battery compartment during installation.

A:To Open and Close the Battery Compartment Cover

To open the battery cover, push the latch forward toward the top of the remote control, and lift the latch up.

To close the battery cover, slide the battery cover straight back in (toward the top of the remote) and push down until it “clicks” into place.

B:Low Battery Message

When the Liquid Crystal Display (LCD) flashes L_BAT, the batteries should be replaced.

Note: Batteries should last about 6 months under normal conditions. This remote control will retain its programmed memory for up to one year after the batteries are removed and up to ten years after the batteries go “dead”.

IMPORTANT NOTE:

The PAV’s remote may be programmed to control up to eight devices, including the PAV. Before using the remote, it is important to remember to press the Device Control Selector button that corresponds to the unit you wish to operate. Before using the remote with other products, follow the instructions in Programming and Using the Remote Control.

It is also important to remember that many of the buttons on the remote take on different functions, depending on the product selected using the Device Control Selectors. The descriptions shown here primarily detail the functions of the remote when it is used to operate the PAV.
