[. . . ] Fully Integrated Digital Recording Systems 1212 I/O PCI MULTI-CHANNEL AUDIO INTERFACE English Owner's Manual The FCC Regulation Warning English This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules and CISPR pursuant to subchapter EN 55022 of the EMC Directive. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. [. . . ] If this parameter is set incorrectly, the connected S/PDIF device may not function properly. The internal sample rate and S/PDIF output will be set to 44. 1 kHz. The internal sample rate and S/PDIF output will be set to 48 kHz. English Analog Input Trim Left 0dB to -78dB, OFF. This allows you to attenuate the analog input sensitivity of the left channel, prior to the A/D conversion. At the Korg 1212 I/O 25 1212 I/O Utility maximum value of 0dB, the volume of the input signal will be unchanged. At lower values, the volume will be reduced. At the minimum value of OFF, the input signal will be completely muted. In general, it's best to leave the input pad set to 0dB, and attenuate only when necessary to avoid digital clipping. If you're using an external mixer, you may find it more convenient to reduce the output level of the mixer. Also, if you find yourself routinely attenuating by around -12dB, this may mean that the 1212 I/O is configured for -10 levels, while the rest of your system is operating at +4. For more details on setting the 1212 I/O's analog levels, please see "Analog levels: +4 or -10" on page 3. This allows you to attenuate the analog input sensitivity of the right channel, prior to the A/D conversion. It works just the same as the control for the left channel, as described above. English Sound Manager Routing (MacOS) The Apple Sound Manager offers two audio inputs and two audio outputs, each of which can be routed to (or from) any of the 1212 I/O's twelve input channels and outputs, respectively. For more information on setting up and using the Sound Manager, please see the section titled "Sound Manager (MacOS), " starting on page 39. If the 1212 I/O is not selected for use with Sound Manager (as described under "Sound Manager (MacOS), " starting on page 39), the Sound Manager Routing parameters will be inactive and grayed out. If the 1212 I/O is selected for input only, then the output parameters will be grayed out; if it is selected for output only, then the input parameters will be grayed out. If you have multiple 1212 I/O cards installed in your computer, select the same card for Sound Manager input and output. If the current card (as set in the 1212 I/O In PCI Slot parameter) is not assigned for use with the Sound Manager, the input and output parameters will be grayed out, as described above. Input L Analog L, Analog R, S/PDIF L, S/PDIF R, ADAT 1-8. This selects the 1212 I/O input channel which will be routed to the Sound Manager's left input channel. Input R Analog L, Analog R, S/PDIF L, S/PDIF R, ADAT 1-8. This selects the 1212 I/O input channel which will be routed to the Sound Manager's right input channel. 26 Korg 1212 I/O 1212 I/O Utility Output L Analog L, Analog R, S/PDIF L, S/PDIF R, ADAT 1-8. [. . . ] If the problem goes away, then there is an interaction with that card's video driver. If this is the case, contact the video card's manufacturer. They may have an updated driver or a switch similar to the Matrox above that addresses the problem. Timecode Synchronization Digital audio program repeatedly tries to locate, but does not remain locked In Deck, try increasing the SMPTE Pre-Roll time; insufficient Pre-Roll settings may cause locates to fail. In general, this should be a minimum of 4 seconds. [. . . ]
