DP564 Multichannel Audio Decoder

Chapter 1

Introduction

The DP564 Multichannel Audio Decoder gives studio professionals unparalleled ability to monitor different audio programs in a variety of listening modes.

Critical monitoring is essential to ensure that the highest quality audio reaches your listeners at home. The DP564 Multichannel Audio Decoder, the next generation reference decoder from Dolby Laboratories, is the perfect tool for monitoring and quality control applications in DTV broadcast, postproduction, and DVD authoring.

The DP564 enables decoding and monitoring of programs with Dolby® Digital, Dolby Surround Pro Logic®, or regular PCM soundtracks, as well as Dolby Digital Surround EX™ and Pro Logic II decoding, making the DP564 the ideal digital reference decoder for both Dolby Digital and Dolby Surround audio.

With the DP564, you can easily monitor all of Dolby Digital’s unique downmixing capabilities. This means content producers and providers can verify how material delivered in a 5.1-channel format will sound on systems that offer only Dolby Surround, two-channel stereo, or mono playback.

By switching between listening modes using the front-panel controls, it is possible to monitor how any multichannel program will sound when played on fully configured multichannel surround systems, as well as surround systems with no Center channel (Phantom) or even systems with no Surrounds (3 Stereo). Compression modes can also be selected from the front panel to easily monitor Dolby Digital’s dynamic range control and dialogue normalization features. These features are tailored to professional users to allow you to hear how your audio will sound on any set-top box, DVD player, or home theater receiver.

To set up and control the monitoring environment, the DP564 offers comprehensive monitoring functions—including a master volume knob on the front panel, channel mutes, reference monitoring level, individual channel level trims, center and surround channel delays, bass management, and both full and band-limited pink noise for quick and accurate room calibration. The headphone output has its own volume control, as well as Dolby Headphone processing, which provides surround sound monitoring over standard headphones. This allows more accurate QC monitoring and reduced listener fatigue for headphone listeners.

Figure 1-1 shows the DP564 system block diagram.

DP564 Multichannel Audio Decoder	Introduction

Figure 1-1 DP564 System Block Diagram

The 2-U rack-mount unit features multiple inputs including two AES3 inputs, a Toslink optical input, and an Ethernet port for RTP-streaming Dolby Digital audio. The inputs are easily selected with dedicated front-panel buttons.

The front panel also incorporates a display screen, featuring high contrast and a wide viewing angle. In addition to providing an intuitive interface for menu access and setup, the display is easy to read and offers clear graphic status menus for all Dolby Digital metadata settings and metering of output levels and dynamic range control.

The rear panel includes the main audio output connections for both digital AES3 and analog +4 dBu balanced outputs. A linear timecode (LTC) output generates timecode from a Dolby Digital bitstream, allowing DVD facilities to check A/V sync between encoded Dolby Digital audio files and uncompressed video. Frontand rear-panel serial interfaces and an Ethernet port enable remote control and software updates; a remote control software application is included to configure and control the DP564 from a PC via Ethernet or serial connection. Remote control is also possible from an optional dedicated hardware controller—either the Dolby Cat. No. 549 GPIO Controller or another system using the general-purpose I/O connector (GP I/O).

Installation

This chapter covers the physical connections necessary to operate the DP564.

2.1Mounting

The DP564 occupies 2U of rack space. The unit operates at ambient temperatures up to 122° F (50° C) and vents from front to rear.

Caution: Do not mount the DP564 directly above heat-generating equipment. Ensure adequate ventilation. The temperature inside a poorly ventilated rack can be considerably higher than ambient room temperature.

2.2Rear-Panel Connections

The rear-panel connections include BNC inputs and outputs, an optical input, serial ports, analog audio outputs, and the power supply. It is best to make all other connections before connecting the power supply.

2.2.1BNC Connectors

Figure 2-1 shows the BNC connectors. These are compliant with the AES3-ID standard.

DP564 Multichannel Audio Decoder	Installation

signal on to another unit; if pass-through is not necessary, this connector should be fitted with a 75-ohm terminator.

The Digital In connectors, AES 1 and AES 2, can receive both Dolby® Digital and PCM signals. The decoder recognizes each signal type and processes the signal appropriately. Digital inputs can also be received using the Optical In and 100BASE-T inputs shown in Figure 2-2.

The LTC Out connector provides a SMPTE 12M linear timecode output signal. Timecode is extracted from the timestamp embedded in a SMPTE 337M bitstream that may be present in a Dolby Digital signal.

The Digital Out connectors provide a digital output signal for connection to a digital monitoring system. Each connector is labeled according to the channel pair it contains.

2.2.2Optical In and Serial Ports

Figure 2-2 shows the Optical In and the serial connections.

Optical In 100BASE-T	Remote RS-485	37	GP I/O	20

Figure 2-2 Connection Ports for Optical, Ethernet, Remote, and GPI/O

The Optical In connection can receive both Dolby Digital and PCM signals. The decoder recognizes each signal type and processes the signal appropriately.

The 100BASE-T port can connect to a 100Base-T or 10Base-T network. The connection can then be used for streaming audio, and to enable the DolbyRemote 564 remote control application. See Chapter 8, Streaming Server and Remote Software, for details.

The Remote RS-485 port can connect to a computer running DolbyRemote 564. The DolbyRemote 564 application is far more efficient, however, when connected via the 100BASE-T port. For details, see Chapter 8, Streaming Server and Remote Software.

The GP I/O port connects to the Dolby Cat. No. 549 GPIO Controller (sold separately) or to a separate remote control device, which must be configured according to the pinout information under GPI/O Configuration in Section 4.4.4, I/O Control.

2-2

DP564 Multichannel Audio Decoder	Installation

2.2.3Analog Outputs

The +4 dBu balanced Analog Audio Outputs connect directly to your monitoring system. Each connector is labeled according to the channel signal it sends.

If your system includes a single speaker for Back Surround, use only the Bsl output, and leave the Bsr output open.

2.2.4Power

The main fuse rating is:

T 1A L (1 amp, 250 V, 20 mm, time-lag, low breaking capacity) for all operating voltages.

WARNING: Before applying power, check the main fuse using the procedure on page ix.

There is no power switch on the DP564. To apply power, connect the power cord to a live outlet.

one-touch recall of a complete set of parameter settings previously stored as a preset. Output-level controls set the volume level for your listening environment. Detailed explanations of each button function follow.

3.2Button Functions

Each button on the front panel controls a function or functions in the DP564. These functions are defined in this section.

Any time a feature is active, the front-panel button associated with that feature is lit. This is true whether the feature is activated or deactivated manually, or controlled by program metadata, GPI/O, or a preset configuration.

Setup

The primary function of each button in this group is printed on the button. To perform the alternate function (printed on the panel above or beside the button in yellow text), press Shift, then the button associated with the desired function. When you press Shift, that button stays lit until you press another button, or press Shift again to disable the alternate-function selection.

In this group of buttons, there is one function that goes beyond navigation: Bypass. If the DP564 receives a PCM signal while in bypass mode, it passes the signal straight to the Left and Right channel outputs with no processing. If the DP564 receives a Dolby® Digital signal, it decodes the signal, but all further processing is disabled. This includes dialogue normalization, dynamic range control, and downmixing, as well as all surround formats, bass management, and channel delays. Channel level trims and master volume continue to function. When you select Bypass (Shift, then Esc), bypass mode remains in effect until you disable it by using the same button combination. When you disable bypass mode, the unit returns to the settings in effect when you entered bypass mode.

The navigation buttons work in combination with the display screen menus. In setup menu screens and the Metadata Status, Error Status, and System Status screens, pressing Enter enters the submenu for the highlighted selection, and pressing Esc returns to the next higher menu level. If you are at the top of a menu structure, Esc has no effect. If you change a value for a parameter in the setup menu, Enter activates the new value and returns to the next higher menu level, and Esc discards the new value and returns to the next higher menu level. For details on menu structure, see Chapter 4, Menus.

The default menu at startup is the status menu. The status and setup menus have separate functions and structures, detailed in Chapter 4, Menus. If you are in a status menu, Setup changes the display to a setup menu. If you used the setup menu within the previous five minutes, it returns you to the last setup menu you saw. If you have not used a setup menu within that time, pressing Setup displays the top-level setup

▲ moves the item selection in the display to the next item up. In the setup menu, if the current menu designates a numerical value, ▲ increases the value to the next higher increment.

► navigates within and between menus. In the setup menu, ► enters that item’s submenu, unless there is no submenu. In the status menu, ► scrolls to the next available menu. Brightness takes you directly to the menu where you can adjust the intensity of the display.

▼ moves the item selection in the display to the next item down. In the setup menu, if the current menu designates a numerical value, ▼ decreases the value to the next lower increment.

◄ navigates between menus. In a multi-layer menu, ◄ returns to the next-higher menu (same as Esc). In the top-level status menu, ◄ scrolls to the adjacent menu, (in the opposite scrolling direction as ►). Remote invokes remote control by the DolbyRemote 564 software. When the DP564 is under remote control, Remote ends remote control and re-activates all front-panel controls.

Note: When the DP564 is under remote control, most front-panel controls are inactive. In this mode, the Master Volume knob is active, and you can scroll through the status menus, or press Remote, which ends remote control and reactivates all front-panel controls.

3.2.2Listening Modes

Stereo (Lo/Ro)

Lt/Rt

Mono

By reproducing the wide variety of consumer listening environments, listening mode selections enable you to make sure the audio program is optimized for every listening situation. The selections are divided into four categories: Downmix, Decode,

Listening, and Compression.

Downmix

Use the Downmix buttons to select the downmix you monitor. Lo/Ro downmixes to a stereo output. Lt/Rt downmixes to a Dolby Surround Pro Logic® compatible stereo output. Lo/Ro and Lt/Rt are unavailable if the Dolby Digital input signal is in audio coding mode 2/0, 1/0, or if the input signal is PCM.

Mono summing is available only if the input is PCM, a Dolby Digital signal in audio coding mode 2/0, or any other Dolby Digital signal downmixed to Lt/Rt or Lo/Ro.

EX

Decode

Use the Decode buttons to select a specific surround-decoding mode.

Note: Dolby Digital decoding is applied whenever a Dolby Digital signal is received. The Decode buttons offer additional processing options.

EX activates Dolby Digital Surround EX™ decoding. It is available only when decoding Dolby Digital bitstreams with stereo surround channels. You must also have back surround (Bsl, Bsr) speakers selected in the Monitor Configuration menu. Pro Logic and Pro Logic II activate those decoding modes, respectively. The Pro Logic modes are available only if the input is PCM, a Dolby Digital signal in audio coding mode 2/0, or any other Dolby Digital signal downmixed to Lt/Rt.

Note: To quickly access the display screen to adjust Pro Logic II settings, hold down the Pro Logic II button for two seconds.

Listening

Use the Listening buttons to simulate different consumer multichannel speaker systems. Phantom mixes the Center channel signal to the Left and Right channel outputs to emulate a speaker system with no center channel. 3 Stereo mixes the Ls and Rs channel signals to the front-channel outputs to emulate speaker systems with no surround speakers. (Ls routes to L, and Rs routes to R.) Full maps all channel signals directly to the associated outputs. Only one of these modes is active at a time.

Compression

The Compression buttons can apply the dynamic range control profiles available to consumers when decoding Dolby Digital audio. Only one of these modes is active at a time; to disable compression, press the active button.

RF applies the strongest profile available, equivalent to an RF connection to a TV set or small PC speakers. Line applies what appears on some consumer decoders as “light” compression; this is usually the default setting in DVD players and set-top boxes. Custom allows scaling of the Line profile. The factory setting for Custom is 0 percent. At that setting, selecting Custom turns off dynamic range compression. To access the display screen to adjust the percentage setting for custom scaling, hold down Custom for two seconds.

Note: When downmixing, the DP564 automatically applies compression at peak moments to prevent potential signal overload from combining multiple channels, regardless of whether a compression mode is selected.

3.2.3Input

Use the Input buttons to select the source for the input signal. Only one of these buttons is lit at a time, indicating the selected source: AES1, AES2, Optical, or Streaming. If the selected source receives an invalid signal, the Error LED turns red.

3.2.4Preset

Preset buttons 1, 2, 3, and 4 recall and store those preset configurations. To recall any one of those presets, press the associated button and release the button quickly. To store the current configuration as one of those four presets, pick a preset button and hold it down for two seconds or more before releasing. This saves the current configuration and keeps the existing preset name. To rename the preset, use the menus as described in Section 4.4.3, User Presets.

Caution: When recalling presets 1–4 by pressing the Preset buttons, you must release the button in less than two seconds, or that preset will reconfigure to store the current settings.

When you recall preset 1, 2, 3, or 4, the associated button is lit. When you alter any parameter setting, the button light turns off, because the configuration is no longer that of the preset.

3.2.5Output Level

You can control the DP564 output level with the Master Volume knob and the Ref and Dim buttons. The headphone output has its own dedicated volume-control knob. Rotate Master Volume to raise and lower the output level incrementally, within a range of –95 to +10 dB. Ref resets the output level to 0 dB at one touch. Any time the output level is 0 dB, Ref is lit, whether the level was set via button or by Master Volume adjustment. Dim adjusts the output by the amount set in the Dim Gain menu, as discussed in Section 5.4, One-Touch Output Level Adjustment.

The headphone output volume knob controls the output level to the headphone jack only, and is not affected by Master Volume, Ref, or Dim.

When any adjustment is made to the master volume, the middle of the screen momentarily shows the current master volume level.

Menus

Much of the versatility and power of the DP564 lies in its menu structure. This chapter covers:

•Menu basics

•Hot-key function

•Status menu

•Setup menu

4.1Menu Basics

The screen shows information on the current operating status via the status menu, and lets you adjust operational settings using the setup menu. In either menu structure, the title of a menu appears centered above a line at the top of the screen, and information or menu choices display below the line, as shown in the example in Figure 4-1.

Figure 4-1 Operating Mode Menu

In a menu with more options than lines available on the screen, an arrow appears in the title bar to indicate that you can see more by scrolling up or down past the visible items. If menu items are available both above and below the current display, the title bar displays both up and down arrows, as shown in Figure 4-2.

4.2Hot-Key Functions

Certain front-panel buttons activate a special function when you press and hold the button for two seconds. We refer to that function as the hot-key function.

No matter what menu you are viewing, there are three front-panel buttons that display the setup menu for that function when you press and hold the button for two seconds: Pro Logic II, Custom, and Dim. Holding Custom down is the only way to define the parameters for custom compression scaling using the front-panel controls, but those parameters are also adjustable using the DolbyRemote 564 software.

The Preset buttons have a different hot-key function. Holding down any Preset button for two seconds saves the current configuration but keeps the existing preset name. To rename the preset, use the menus as described in Section 4.4.3, User Presets.

Caution: When recalling presets 1–4 by pressing the Preset buttons, you must release the button in less than two seconds, or that preset will reconfigure to store the current settings.

4.3Status Menu

The status menu includes these displays:

•Main status menu

•Output level meters

•Compression meters

•Monitor status

•Metadata status

•Input status

•AES reference input status

•Timecode status

•Error Statistics

•System Status

4.3.1Main Status Menu

At power-up, the DP564 displays the main status menu. If there is no valid input, the main status screen shows No Input.

Figure 4-3 Main Status Menu with a Valid Dolby Digital Input

The main box displays the type of input, sample rate, data rate (in kbps), channel mode, and timecode. Dialogue level displays in the upper right-hand corner.

Timecode information displays according to the option selected in the Timecode Display menu. Timecode information continually updates with the input signal. In the display mode shown here, the timecode display is hours:minutes:seconds:frames. 29 indicates the frame rate—in this case, 29.97 fps. ND indicates non-drop frame status. In a drop-frame condition, those letters read DF, and semicolons separate the timecode units: hours;minutes;seconds;frames. Other options for the timecode information in the main status menu are the timestamp delay word, or blank. Complete timecode information is always available in the Timecode Status menu.

If a preset is in use, the preset number and name display in the bottom left-hand corner. On the right-hand side, any of the four abbreviations shown in Figure 4-3 may appear—these indicate metadata parameters in the Dolby Digital stream. All four will never appear together, as they do in Figure 4-3, because some of those bitstreams are mutually exclusive. The abbreviations are:

•PL (indicating a 2/0 bitstream is flagged “Dolby Surround encoded”)

•EX (indicating a 5.1, 5.0, or 2/2 bitstream is flagged “Dolby Surround EX™ encoded”)

•EB (indicating a bitstream includes extended bitstream information)

•DH (indicating a 2/0 bitstream is flagged as a pre-encoded Dolby Headphone mix)

If there is a valid PCM signal, the display appears as shown in Figure 4-4.

The space above the line displays the type of input, sample rate, bit depth, and mode (Professional or Consumer) of the stream. The DP564 accepts inputs up to 96 kHz, downsampling higher sample rates for processing at 48 or 44.1 kHz. Below

the line, you can still see the preset name and number, but the two-letter abbreviations do not apply to a PCM stream.

4.3.2Output Level Meters

The output level meters screen displays the level of each audio output signal after all decoding, downmix, listening-mode, compression-mode, and bass-management signal processing, but before any channel-level trims or delays.

4.3.3Compression Meters

The compression meters give a clear visual representation of the way in which the dynamic range control is working on a Dolby Digital program. This display shows dynamic range activity for both Line and RF profiles regardless of your Compression selection. This screen also shows the current dialogue level value in the Dolby Digital bitstream.

4.3.4Monitor Status

The Monitor Status menu shows the settings for your current monitor setup, including speaker configuration, subwoofer presence, crossover frequency (for bass management), extended bitstream emulation status, and headphone output mode (stereo or Dolby Headphone profile).

4.3.5Metadata Status

The Metadata Status menu displays the settings for metadata parameters received in the Dolby Digital bitstream. Use ▲ or ▼ to select any parameter, and Enter to view the unabbreviated parameter name and status. You can view extended bitstream parameter status by scrolling to the bottom of the Metadata Status menu to select Extended Bitstream, then pressing Enter. For more information about Dolby metadata, see Appendix A, Dolby Metadata.
