Page 7: Maximizing The Value Of Your Purchase
Maximizing the Value of Your Purchase Congratulations on choosing a superb product. Y our 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. -

Unpacking and Placement Unpacking Unpack your Proceed terials for future transport. Locate and remove all accessory items from the cartons. Accessories include: Important! Installing Batteries in Turn the remote control over and slide the battery compartment cover up and away from the body of the remote. Insert the four alkaline batteries found in the the Remote Control Accessories kit, being careful to follow the polarity indications given on the inside of the battery compartment. -
Page 9: Operating Voltage
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 cor- rect AC operating voltage for your location. -
Page 10: A Word About Installation
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 equip- ment you have chosen to use with your PAV. -
Page 11: Home Theater And The Proceed 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. -
Page 12: Dolby Pro Logic™ Sources
The PAV accurately decodes the Dolby Stereo™ soundtracks available in virtually Dolby Pro Logic™ Sources all modern film soundtracks, many television shows, and even some music re- cordings. It does so by employing carefully optimized Dolby Pro Logic circuitry, for superior performance and accuracy . Use the ing to most surround-encoded television shows, MTV (most of which is now sur- round encoded), and other surround-encoded program material which has been created for general distribution. -

Pressing the justing the volume will return it to its previous setting. If you adjust the vol- ume 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.

IR input tip polarity 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 tem- perature at all times for optimal performance and longevity . - Page 21 Y our Proceed dealer can help you take advantage of these design features to maximize your system’s versatility. remote turn-on the rear) can be used to toggle Proceed power amplifiers between operate 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.
- Page 22 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 out- puts 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).
- Page 23 If you use the single-ended main outputs, connect them to the correspond- ing inputs of the amplifier being used to drive the Front Left and Front Right speakers. SINGLE-ENDED REMOTE OUTPUTS Single-ended (“unbalanced”) outputs are provided for compatibility with a wide range of associated components, including power amplifiers and elec- tronic crossovers.

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.

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 in- creases bass quantity at the expense of bass quality (by stimulating every room mode supported by the room). -
Page 32: Conventional Surround Placement

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. -
Page 33: System Planning Guide
System Planning Guide Experience shows that almost any reasonable amount of time spent in the plan- ning 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. -

Page 35: System Setup & Calibration
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. -

These allow you to Output Level Calibration compensate for differences in amplifier and speaker sensitivities and for place- ment variations in different rooms. -
Page 40: Setting The Surround Delay
Setting the Surround Delay All Dolby Pro Logic decoders incorporate a delay to the rear speakers. This delay takes advantage of the precedence effect, whereby we tend to localize on the first sound we hear when being confronted with several similar sounds (as in the case of surround sound, or a visit to a reverberant concert hall). -

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. -

Room Acoustics The following information on room acoustics does not need to be considered in every installation.

Page 60: Room Modes
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. The front Left, Center and Right speakers should be the same distance from the wall behind them, and there should be approximate symmetry of the Left and Right speakers with respect to their respective side walls. -
