[. . . ] The dbx® Type IV Conversion System is a proprietary analogto-digital (A/D) conversion process that combines the best attributes of digital conversion and analog recording processes to preserve the essence of the analog signal when it is converted to a digital format. AES Setup The AES Setup sub-menu gives you the status of the following AES information: Data Validity - "Valid" indicates the data is OK. "Invalid" indicates that the Validity bit was set in a frame of incoming data and that the data attached to it may be corrupted. Mode - Select "Consumer" to send information in S/PDIF format. "1" indicates the PCM92 is detecting excessive jitter or noise on the digital audio line. Sample Slip - An unchanging number indicates you are not slipping samples. An increasing number indicates samples are misaligned with the window defined by the Input Source. This may occur when an external master changes sample rate, or when it is just powering up, but should not occur in normal operation. "1" indicates that at least one bit (and therefore at least one audio sample) was corrupted. "1" indicates a Cyclic Redundancy Check error in the incoming data. "1" indicates that at least one bit (and therefore at least one audio sample) was corrupted. 19 MAchINe coNFIG The Machine Config menu lets you configure the PCM92 processor as one, two, three, or four virtual machines in a new preset. Note that once you've selected a configuration, you must then populate each virtual machine with a Machine Preset (see page 11 for more information). Choices include: Single Mono In Stereo Out Single Stereo Dual Mono Cascade Stereo Cascade Mono Cascade Mono to Stereo Combined Stereo Mono In For more detailed descriptions of each configuration, see page 14. MIdI coNtRoL The MIDI Control sub-menu lets you adjust the following MIDI-related options: MIDI Turns MIDI processing on or off. Base Channel Select the connected MIDI device's base channel here. Bank Dump Lets you copy an entire bank of presets from the PCM92 to another device via MIDI. (For a map of banks and presets, see page 26; to see the current preset's bank number, press Knob C while viewing the Preset screen. ) When Bank Dump is highlighted, turn the corresponding B or C Knob to select a bank. Press the corresponding B or C Knob to send the bank to the connected device. teMPo coNtRoL The Tempo Control sub-menu contains the following options: Tempo Value Set the current preset's tempo here by turning Knob A, or by pressing the Tap Tempo button at least two times. If, for example, the rate is 120 BPM, and you select eighth-note here, the tempo will be 120 eighth-notes per minute. If you select quarter-note here, the tempo will be 120 quarter-notes per minute. (The factory default is quarter-note. ) 20 Tempo Source Select INTERNAL to determine the tempo using parameters within the PCM92, or MIDI to set the tempo using MIDI beat clock. Refer to your DAW's manual to learn how to transmit this value. NetWoRK coNFIG Here you can set the PCM92 Subnet Mask, IP Address, Gateway, and DHCP information. Turn the Select knob to select a three-digit number (of the DHCP value) and turn Knob A to change the number (or the DHCP value). [. . . ] When this is selected the signal rate parameter is used to control rate. When this is selected the signal rate parameter is used to control rate. When this is selected the signal rate parameter is used to control rate. White Noise (correlated) -- sends identical white noise to all outputs White Noise (decorrelated) -- sends decorrelated white noise to all outputs. [. . . ]
