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.
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.
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.
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.
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.

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.
9 MUTE 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.
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.

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.

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 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.
4 AC 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.
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.
7 REMOTE 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).
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. 10 SINGLE-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).

2 BANK SWITCH The PAV learning remote has two complete “banks” of settings which may be stored for your use. As delivered from the factory, many but not all of the buttons in the “Proceed” bank (the one in use when the sliding switch is under the Proceed logo) have been preset to control the PAV. The remaining buttons in the Proceed bank are available to operate your primary source component(s). In this way, you should rarely have to switch to the second bank of controls.
5 e, f, g, h, std by BUTTONS The first four of these buttons are simply more “extras” provided for your convenience, as with a through d above. You may want to program them for direct access to your favorite surround modes (THX cinema, pro logic, stereo surround, surround off), for example. The PAV can teach such “Direct Access” commands directly to your remote control. For more information, see Programming the Remote Control. The std by button will place the PAV into standby mode.
• path: pressing this button will cycle the PAV through the various signal paths. Having selected a particular path, subsequent source selections affect only that path (e.g., main, remote, both, or record). • recall: pressing this button restores the various channel offsets to their calibrated, most accurate settings (set up during installation and calibration). You can experiment with adjusting the levels of the subwoofers, center channel, surrounds, etc.
Planning Your Installation The information contained within this section is intended to help get someone started who wishes to design and install their own sophisticated A/V system built around the Proceed PAV. However, it cannot be considered a substitute for the experience, expertise and specialized training of an audio/video installation professional. (See A Word About Installation, page 9.
Attention should be paid to the accessibility of the infrared control signal to the components. Most people instinctively aim remote controls at the screen, without thinking about the location of the equipment. It is a good idea to locate a small infrared “repeater” in the vicinity of the screen, set up to relay the signal into the equipment area and/or the PAV’s remote IR input. This is especially true if the equipment has been isolated from plain view, inside cabinetry.
toe-in of left & right speakers L sur sub L C R R sur Some toe-in of the Left and Right speakers toward the main listening area (see above) will help minimize side wall reflections and balance the sound for people at the extreme edges of the viewing area. Placing the center speaker at the same distance as the left and right is also important (note the arc in the diagram above).
phase-induced irregularities at the crossover frequency of 80 Hz.) Of these two guidelines, the first is usually more significant sonically, as it tends to minimize the audibility of the room’s modes. Avoid corner placement, as this typically increases bass quantity at the expense of bass quality (by stimulating every room mode supported by the room). The actual number of subwoofers used in an installation will depend on both the size of the room and on the manufacturer’s design.
conventional surround placement sub L sur L C R sur The Wiring example wire lengths chart Working in Unusually Large Rooms R Low impedance speaker wire must be used throughout the system. This ensures the most efficient transmission of power from the amplifiers to the speakers, which minimizes several forms of audible distortion. Surprisingly, not all speaker wires (including some of the audiophile variety) meet the necessary criteria.
System Planning Guide Experience shows that almost any reasonable amount of time spent in the planning stages will pay for itself two to three times over during the installation— more if the installation crew includes two or three people. With the background provided in the previous sections, the planning process can be boiled down to a checklist which will ensure that you do not overlook anything important. Video Placement ■ The primary seating area should be perpendicular to the picture.
■ ■ ■ ■ ■ ■ ■ Additional Notes on Speaker Placement 34 the same distance from the main listening area as the Left and Right speakers. If THX-certified LCR speakers are used and must be either above or below ear level when seated, aim them down (or up) into the listening area. They are intentionally quite directional in the vertical plane, to improve dialog intelligibility and localization. Placing the LCRs below the screen is generally preferable to placement above.
System Setup & Calibration The PAV uses on screen menus to make the initial setup of this sophisticated control center as simple as possible. In addition, there are a few on screen menus which can be used occasionally, if you change your preferences as to how the system should operate. Operating the On Screen Menus with the Remote There are five keys on the remote control which are used to “navigate” through the on screen menu system.
Setting Up All surround processors require a certain amount of setup before they can perform correctly. This fact is also true for audio/video preamplifiers such as the PAV which incorporate surround processing as part of their design.
If your system does not include a center channel speaker, choose “none.” Doing so will place the PAV into a “phantom” center channel mode wherein the information which would normally be directed to the center speaker by the Pro Logic circuitry will instead be sent equally to both left and right speakers. This process creates an illusion of a center channel speaker for those sitting on the centerline between Left and Right speakers.
have a poorly-defined image smeared all over their end of the room. • L–C Phasing: check Left-Center phasing in the Home THX mode by repeating the L-R Phasing test after having moved the interconnect from the Right speaker’s amplifier input to the Center speaker’s amplifier input. Don’t forget to move the interconnecting cables back where they belong when you are done. • Absolute Subwoofer Phasing: it is also important for both subwoofers to have the correct phase with regard to the rest of the system.
ing differences in level between various sources (some of which may seem “louder” than others without such a correction). Output Level Calibration LEFT FRONT The PAV also incorporates level controls for each output. These allow you to compensate for differences in amplifier and speaker sensitivities and for placement variations in different rooms. These adjustments are essential for reproducing proper soundstaging and image localization.
Setting the Surround Delay 3 REPEAT THIS PROCESS FOR EACH SPEAKER IN TURN Pressing master will move the cursor (and the noise) on to the next speaker. When adjusting the subwoofer level, be sure to get up and walk all around the listening area, watching for the magnitude of the variations introduced by room modes at low frequencies. If more than 3-4 decibel variations are seen within the listening area, consider re-locating your subwoofers for more consistent results.
3 ADD 15 TO THE NUMBER OBTAINED IN STEP #2 AND SELECT THIS SUM IN THE SET DELAY MENU For example, if your rear speakers are 7 feet closer to you than the front speakers, add 7 to 15 to get 22 msec, which is the optimum delay for your system. Use the volume +/– keys to set this value in the set delay menu. 4 MAKE A NOTE OF THESE SETTINGS UNDER “YOUR SYSTEM SETTINGS” IN THE BACK OF THIS MANUAL Having these settings handy will prove helpful should anyone ever tamper with your careful calibrations.

the main display. (See Operating the On Screen Menus from the Front Panel, page 35.) Changing the PAV’s IR Address Important! In some installations, you may discover that some other company is trying to use the same infrared control codes used by the PAV, or vice versa. (This unfortunate circumstance has become more common in recent years thanks to the explosion of IR-controlled products in the home.
Using the PAV Setting the Volume There are, in effect, two volume controls in the PAV. When in either THX cinema or pro logic modes, the input level control should be used to compensate for differences between recordings, using its associated green LED as a guide. Adjustments to allow for personal preferences, late-night listening, and the like should then be made with the master volume control.

You may find that increasing the level of the rear speakers is necessary in order to bring what little ambience is in a “dry” recording up to a more enjoyable level. Mono Surround The mono surround mode can provide a sense of spaciousness and size to monophonic program material such as some historical recordings and movie classics such as Casablanca or The Wizard of Oz.

Programming the Remote Control Programming Other Components’ Functions The remote control provided with the PAV is capable of learning the commands of almost any other remote control. This is true of any and all buttons on the remote, including those that are pre-programmed from the factory to operate specific PAV functions. If you find that some other configuration of the PAV remote control better suits your particular needs, you are free to assign any command to any button.

Programming PAV Functions If you inadvertantly overwrite one or more PAV commands in your PAV remote control, never fear—you don’t have to obtain another PAV remote in order to reteach your own its PAV-specific commands. The PAV itself can send all of the necessary IR commands from its main display window, enabling you to teach the PAV remote both its pre-programmed commands and a few other, optional commands which you might find useful.

Planning Your Remote Control For your convenience, we have included the following form on which you may plan which additional functions you will assign to which buttons on the PAV remote control. We suggest photocopying this page and then planning your programming before getting into it too heavily. A little time spent planning can make the teaching process go much more smoothly, and it provides you with a ready reminder of which commands you placed where during the first day or two of use.

Room Acoustics The following information on room acoustics does not need to be considered in every installation. Rather, it is provided for those who plan a dedicated listening room, or for those who feel they have a problematic room and therefore need ideas about how to improve their system’s performance further. Once again, the value of your dealer’s experience should never be underestimated.
The Boundary Effect is particularly important when it comes time to position the front speakers. If they are not placed consistently with regard to adjacent room boundaries, the tonal balance or timbre of sounds panned across the front may change, weakening the illusion of a real object moving across the soundstage.
Your System Settings The settings in your Proceed PAV are saved in non-volatile memory and should normally survive power outages. Still, it is a good idea to write your preferred settings down against the chance of an inquisitive neighbor or family member changing them without your knowledge. Please use the following form to record your system’s settings against such a possibility.

Troubleshooting Your Proceed PAV has been designed to deliver many years of satisfaction. It has also been designed to allow an unusual amount of “customization” so as to make it suitable in a wide variety of (possibly changing) circumstances. This flexibility necessitates a certain amount of setup before the unit can be expected to perform correctly—in effect, one must inform the PAV of its environment so it may make the right “decisions” about what it should do.
Care and Maintenance To remove dust from the cabinet of the PAV, use a feather duster. To remove dirt and fingerprints, we recommend isopropyl alcohol and a soft cloth. Caution! Always apply the isopropyl alcohol to the soft cloth and then wipe the PAV with the dampened cloth. Never pour or spray even small amounts of any liquid directly on the PAV, as doing so may allow the liquid to reach the circuitry inside the unit.
