User manual RANE RC 24T

[. . . ] Set the AES/EBU or SPDIF SELECT SWITCH to the appropriate position to select the proper input. Connect the AES/EBU OUTPUT on the rear of the RC-24T to whatever is receiving the 24-bit digital audio signal during playback (and monitoring). Connect the supplied Rane RS-1 remote power supply to the red POWER jack on the rear of RC-24T. Press the DIGITAL IN button on the DA-88 to select the TDIF-1 interface as the audio signal source. [. . . ] This switch engages 16-bit dithering and truncation on the AES/ EBU OUTPUT. Dither should be engaged when the AES/EBU OUTPUT is feeding a device that truncates the signal to 16 bits (e. g. The dithering used by the RC-24T follows the Triangular Probably Density Function described by Stanley Lipshitz and John Vanderkooy in their paper: "Resolution below the least significant bit. . . ". REAR PANEL DESCRIPTION 1. The AES/EBU OUTPUT transmits digital audio conforming to the AES/EBU standard. Digital audio exiting this Output is identical to the original digital audio fed to the AES/EBU (or SPDIF) INPUT and recorded onto the DA-88. This Output is typically connected to a D/A converter, hard disk recorder or a CD mastering system. The AES/EBU OUTPUT follows international conventions, with pin 2 hot, pin 3 negative, and pin 1 tied to chassis ground. The AES/EBU Input receives digital audio following the AES/EBU standard. This Input follows international conventions, with pin 2 hot, pin 3 negative, and pin 1 tied to chassis ground. This input is typically connected to the digital audio source, such as an A/D converter or the output of a digital mixer. The SPDIF Input is just like the AES/EBU INPUT, except data received here is formatted with the consumer "Sony Philips Digital Interface Format". This switch allows you to select the desired input (SPDIF or AES/EBU). Another way of putting it is: you must select the proper input (the one you plugged a cable into). Note: The RC 24T generates the DA-88 WORD SYNC from the AES/EBU (or SPDIF) input. Therefore, it is necessary for the A/D converter (or whatever your AES/EBU source is) to feed the PAQRAT AES/EBU (or SPDIF) INPUT at all times (whether you're recording or playing back). This connector interfaces the RC-24T to the DA-88 modular digital multitrack. This Output sends a digital audio synchronization signal to the DA-88. It must be connected to the DA-88's WORD SYNC IN connector with a typical BNC cable (terminated with male BNC plugs on each end). Failure to connect this cable will prevent the RC-24T from synchronizing with the DA-88. Caution: Never connect anything except the Rane RS 1 AC power supply (enclosed with the unit) to the thing that looks like a red telephone jack on the rear of the RC-24T. This is a low-voltage AC power input, and connecting it to telephones, computer keyboards, or other devices will result in unpredictable, and potentially catastrophic, results. If you want to destroy your RC-24T, we suggest wiring it to the output of a power amplifier, or dropping it out of an airplane. IMPORTANT NOTE FCC & VDE NOTICE 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 similar requirements found in European specifications VDE 0871/0875. [. . . ] The resultant audio file then needs to be converted to 16-bit only once, and the nasty artifacts are kept to a minimum. The 24-bit files can be backed up through a PAQRAT to maintain the highest quality in the audio data. When mastering a project that was mixed 16-bit, use the PAQRAT to make an EQ safety. The output from digital mastering consoles is usually 24-bit (the 24-bits is generated by the math used to perform digital EQ, limiting, compression and level changes). [. . . ]
