Page 7: Chapter 1 Introduction
DolbyRemote Overview The DolbyRemote application is used to remotely control the entire range of Dolby Laboratories Inc. Dolby Digital encoders. Key features of the software include: Control of several Dolby professional audio products from a single instance of the DolbyRemote application, hardware permitting. Off-line mode, without the presence of a unit, to create and edit parameter files. -

Laboratories. Click Next to accept the default or click Browse to select an alternative location. 7. Use the program folder default Dolby Laboratories or enter an alternate folder name and click Next. 8. Insert the DolbyRemote Software Install Disk 2 when prompted to do so and click 9. -
Page 9: Cable Installation
D-9 end of the cable. The other end of the cable connects to the Remote port on the front panel of the encoder. Additional cables may be purchased from Dolby Laboratories. RS-485 connection for the DP567/DP569 requires a separate cable, not provided. -
Page 11: Chapter 2 Establishing Communication
Starting DolbyRemote From the Windows Start button, select DolbyRemote from the folder in which you installed the DolbyRemote application. The Open Device window is displayed, Figure 2-1. Figure 2-1 DolbyRemote Open Device Window 2.1.1 Device Type Selects the Dolby encoder model to be controlled. Choices are DP561, DP567 or DP569. 2.1.2 Communications These settings control the communication parameters for the DolbyRemote application. -

DolbyRemote Installation and Operation through the front panel of the encoder. The rate you select in DolbyRemote must match the rate selected in the unit. Address The default address setting for the DP567 and DP569 is 0x8280. If the address has been changed from the front panel of the encoder, set the remote address accordingly. -
Page 13: Additional Devices
DolbyRemote Installation and Operation Additional Devices The DolbyRemote application can control several Dolby professional audio products. If you have more than one device you may control them all from a single instance of the DolbyRemote application, hardware permitting. To add additional encoders, click the New button or select File, New Device. The Open Device window is again displayed. -

Saving and Restoring Configurations DolbyRemote can save the configuration of the active device so that it can easily be recalled later. The file extension for these configurations is .dby and can only be read with DolbyRemote. Configurations can be transferred between different devices of the same type, without complication, using this function. - Page 16 DolbyRemote Installation and Operation...

Page 17: Chapter 4 Dolby Digital Parameters
This chapter briefly describes each of the parameters available in the windows of DolbyRemote. It is designed as a quick reminder for experienced users or as an introduction for new users rather than the full explanation that will be required. Detailed information about each encoder setting can be found in the relevant encoder user’s manual or in the pages of the Dolby Digital Professional Encoding Manual. -
Page 18: Data Rate
DolbyRemote Installation and Operation 4.1.2 Data Rate Data Rate determines the bit rate of the encoded Dolby Digital bitstream. All data rate options are allowed, however, selection of the data rate is dependent on the settings of the Audio Coding Mode, Sample Rate and Auxiliary Data parameters. Certain low data rates may not be supported in all channel modes. -
Page 19: Lfe Enable
DolbyRemote Installation and Operation designated as two numbers, A/B, with A indicating the number of front channels, and B indicating the number of rear (surround) channels. The following table lists all eight modes and defines which input channels are used for encoding based on the selected mode. -
Page 20: Audio Bandwidth
DolbyRemote Installation and Operation many different program types, with different reference levels, can be encoded with full dynamic range and then be decoded to give a uniform loudness level. 4.1.8 Audio Bandwidth Audio Bandwidth displays the current audio bandwidth of the main channels. This is dependent on the number of channels being encoded and the data rate. -
Page 21: Coding Delay
DolbyRemote Installation and Operation Encoder State Encoder State displays the status of encoding for the current device. There are three options for the encoder state: • Not Encoding—the user has requested that the unit start encoding, but the encoder is unable to encode because it is missing a required input signal. •... -
Page 22: Preprocessing
DolbyRemote Installation and Operation Preprocessing 4.2.1 Input Filtering Deemphasis The Deemphasis parameter controls whether or not 50/15 µs digital deemphasis may be applied to the main input channels before the Dolby Digital encoding process is performed. If Deemphasis is set to Disabled, deemphasis will never be applied and the emphasis channel status bit of input signals will be ignored. -
Page 23: Surround Channel Processing
DolbyRemote Installation and Operation 4.2.2 Surround Channel Processing 90 Degree Phase Shift 90 Degree Phase Shift controls whether or not a 90-degree phase shift is applied to the surround channel(s) before the Dolby Digital encoding process. Its use enables decoders to create a Dolby Surround compatible two-channel downmix. This parameter is disabled if the encoding mode does not include any surround channels. -
Page 24: Bitstream Info
DolbyRemote Installation and Operation custom compression modes. The default setting for RF Overmodulation Protection is disabled. This parameter is not available on the DP567. Input Level Meter Input Level Meter shows the input signal that the compressor is using to determine the amount of boost or cut. -
Page 25: Audio Production Information
DolbyRemote Installation and Operation Surround Mix Level Surround Mix Level is a parameter that indicates to the decoder the nominal downmix level of the surround channel(s) with respect to the left and right channels when listening in stereo. This is only active when in 2/1, 2/2, 3/1, or 3/2 coding modes. -

Page 27: Input And Output Settings
DolbyRemote Installation and Operation Input and Output Settings 4.5.1 Input Lock Status Lock Status shows whether the input channels for the current coding mode have been detected and locked by the encoder. Sample Rate Sample Rate shows the sample rate of the digital input channels. Integrity Integrity shows the data integrity of the digital input channels. -
Page 28: Channel Assignment
DolbyRemote Installation and Operation • Autodetect: Automatically detects and processes PCM and pre-encoded bitstreams. Invalid bitstreams will be assumed to be PCM data, and encoding will be enabled. Aux Data Aux Data allows you to indicate whether the auxiliary data field is present in the encoded Dolby Digital bitstream. -
Page 29: Input Subcode Status Bits
DolbyRemote Installation and Operation Audio Bit Audio Bit allows you to set the audio bit in the output bitstream as either audio or non-audio, data. Certain AES/EBU inputs may require this to be set to audio before they will record the encoded bitstream. Multiplex Mode Multiplex Mode allows multiple encoded bitstreams to be combined into the main digital output bitstream. -
Page 30: Stream Number
DolbyRemote Installation and Operation does not guarantee that a valid test tone will be produced at the output of the DP567 or DP569. Dolby Digital encoding must also be active, which requires that the selected clock source be valid. The selection of a Test Tone mode automatically overrides the input format settings. -
Page 31: Reference Input Subcode Status Bits
DolbyRemote Installation and Operation Stream Number Stream Number shows the stream number for a pre-encoded bitstream present at the reference input. 4.6.2 Reference Input Subcode Status Bits These show the format, sample rate and audio bit as indicated in the subcode of the reference input signal. -

Page 35: Chapter 5 Troubleshooting
Opening a Device If the DolbyRemote application is unable to communicate with the unit, check the following: DP569/DP567 Make sure the unit is in remote mode (press shift-left arrow). The remote LED should be lit. Make sure that you are either using a RS-232 connection through the front panel or a RS-485 (RS422 for DP567) connection through the rear panel. -
