INTRODUCTION

Thank you for purchasing the Marantz DP870 Dolby Digital Surround demodulator/decoder. This remarkable component has been engineered to provide you with many years of home theater enjoyment. Please take a few minutes to read this manual thoroughly before you connect and operate the DP870. As there are a number of connection and configuration options, you are encouraged to discuss your own particular home theater setup with your Marantz A/V specialist dealer.

DESCRIPTION

Dolby Digital (also known as AC-3) is a new technology that was originally developed to provide six separate channels of high-quality discrete multi- channel sound for motion picture theaters. The Marantz DP870 Dolby Digital demodulator/decoder brings that same high-quality sound into your home when used with a compatible laser disc player, as well as from future Dolby Digital sources such as DSS, Digital Video Disc (DVD) and High Definition Television (HDTV). The wide dynamic range of Dolby Digital enables the Marantz DP870 to reproduce soundtracks with their full fidelity and a realism that is not possible with conventional matrix surround systems.

Depending on the specific equipment in your home theater setup, the DP870 can be connected in one of three configuration options:

• Direct connection to A/V receivers such as the Marantz SR-96/SR870 that feature a SIX CHANNEL DIRECT INPUT.
• Connection between your existing A/V surround processor/pre-amp, such as the Marantz AV600, and your power amplifier(s) and subwoofer (for owners of separates-based home theater systems).
• Connection to the PRE-OUT/MAIN-IN jacks on the rear panel of your A/V receiver, provided that it is equipped with 5 pre-out/mainin jack pairs and a sub woofer output jack, such as the Marantz SR-92/SR-92mk2 and SR-82/SR-82mk2 models.
  The DP870 is manufactured under license from Dolby Laboratories Licensing Corporation. “Dolby”, “AC-3”, and the double-D symbol! OO are trademarks of Dolby Laboratories Licensing Corporation.

SYSTEM SETUP & CALIBRATION

The DP870 delivers optimal performance when it is used with the Marantz SR-96, although it is also compatible with many other home theater system configurations. Please follow the instructions in this section that describe the equipment and speaker choices that most closely resemble that of your own system. Depending on the equipment in use, some of the switches and settings may require adjustment, while in other cases they may be left in their factory preset positions.

SPEAKER SELECTION

The home theater system you already have installed should function provided that there are left, center, and right front speakers, left and right rear/surround speakers, and a subwoofer. For best results, we recommend that the front speakers be of the same type, with identical or similar driver units. This will deliver smooth pans across the front sound stage as the action moves from side to side.
Your center channel speaker is very important as over 80% of the dialog from a typical motion picture emanates from the center channel. Rear channel speakers need to be identical to the front channel speakers, but they should be of high quality. One of the benefits of Dolby Digital AC-3 is that they surround channels are full range, while they were frequency limited in earlier “ProLogic” type systems. Bass effects are an important part of home theater. For optimal enjoyment, a subwoofer should be used as it is optimized for low- frequency reproduction. If you have full-range front speakers, however, they may be used in place of a subwoofer with proper setting of the rear panel switches.
Using the switches on the DP870, however, Using better quality surround speakers will enable you to more fully enjoy the sound quality the DP870 is able to deliver.
For the best advice on speaker selection consult your Marantz dealer.

Speaker system configurations (diagram, as currently used)

If possible, mount the surround speakers on the walls to the sides of the viewing ‘area, 2-3 feet above seated viewers, firing straight across at each other.

SPEAKER SWITCH SETTING

Since the DP870 may be used with a wide variety of speaker types, it is important that you adjust the rear panel speaker switches before using the DP870. Setting these switches will tell the DP870 what type of speakers you are using so that the audio outputs will be directed to the proper speaker.
In general, a “Large” speaker is defined as a traditional full-range speaker that includes a woofer and is capable of reproducing sounds below 100 Hz. For the purposes of this product, a “Small” speaker is one that is not capable of delivering sounds below 100 Hz. Most “satellite” type speakers fall into this category. Before setting the switches make note of the type of front, center, and rear speakers that will be used. For further clarification of your speakers’ type consult the speaker owner’s manual and look on the “specifications” page to find the frequency range.

When you have the information on your speakers, set the four switches as follows:

1. Front Speakers
   This switch determines the frequency range of the front left/right speakers. Select Large or Small depending on the type of speaker you will be using. The factory default setting is “Large”.
   Large: Select this position if you are using full-range speakers that are capable of reproducing sounds below 100 Hz. In this position, the output to the front left/right output jacks is full range.
   Small: Select this position if you have small, frequency-limited satellite-type speakers that do not reproduce sounds below 100 Hz. Do not select this position if your system does not include Subwoofer. In this position, low-frequency sounds are routed to the SUB WOOFER OUTPUT jacks.

2. Surround Speakers
   This switch determines the frequency range of the rear surround speakers. Select Large, None, or Small depending on the type of speakers you will be using. The factory default setting is “Small”.
   Large: Select this position if you are using traditional, large speakers that are capable of reproducing sounds below 100 Hz. In this position, the output to the audio feed to the surround output jacks is full range.
   None: Select this position if you will not be using any rear channel/surround speakers. In this position, the full-range surround audio that would otherwise be routed to the surround channels will be mixed in with the FRONT LEFT and FRONT RIGHT audio.
   Small: Select this position if you have small, frequency-limited satellite-type speakers that do not reproduce sounds below 100 Hz. In this position, low-frequency sounds are routed to either the SUB WOOFER OUTPUT or the FRONT LEFT and FRONT RIGHT jacks depending on the position of the FRONT, CENTER, and SUBWOOFER switches.

3. Center Speakers
   This switch determines the frequency range for the center channel speaker. Select Large, None, or Small depending on the type of center channel speaker installed. The factory default setting is “Small”.
   Large: Select this position if the center channel speaker is a large, full-range model capable of reproducing sounds below 100 Hz. In this position, the output to the audio feed to the Center Channel output jack is full range.
   None: Select this position if you will not be using any rear channel/surround speakers. In this position, the full-range signal audio that would otherwise be routed to the center channel will be mixed in with the FRONT LEFT and FRONT RIGHT audio.
   Small: Select this position if you have small, frequency-limited satellite-type speakers that do not reproduce sounds below 100 Hz. In this position, low-frequency sounds are routed to either the SUBWOOFER OUTPUT or the FRONT LEFT and FRONT RIGHT jacks depending on the position of the FRONT and SUBWOOFER switches.

4. Sub woofer
   Set this switch to determine the routing of low-frequency sounds for all channels. The factory default setting is “ON”, to indicate that a subwoofer is present.
   On: Select this position if the DP870 is connected to an amplifier or receiver equipped with a Subwoofer INPUT terminal, or if it directly connected to a powered subwoofer.
   Off: Select this position if a Subwoofer will not be used. In this position the low-frequency sounds (below 100 Hz) will routed to the FRONT LEFT, RIGHT, and/or CENTER terminals, depending on the setting of the speaker switches for those channels.
