244 Chapter 18-System Examples Two 01Vs & two ADAT-Interface Recorders This example shows how two 01Vs can be used with two 8-track digital tape recorders, or 8-track hard disk recorders, featuring ADAT optical connections to create a 32-input, 16-track fully digital recording system, with the 32 mic/line inputs and 16 digital tape returns providing up to 48 inputs during mixdown. 01V-A and 01V-B are cascaded together using the Stereo Digital In and Stereo Digital Out connections. 01V-B audio signals are combined into a stereo mix, which is then fed to 01V-A via the Digital Stereo Coaxial connections and mixed with the audio signals of 01V-A. The TO HOST connection links the two 01Vs together for simultaneous operation, so when, for example, the fader mode is set to Aux 1 on 01V-A, the fader mode on 01V-B is also set to Aux 1, and vice versa. See "Cascading 01Vs" on page 214 for more information. System Components • Two 01V Digital Mixing Consoles • Two MY8-AT Option I/O cards • Two 8-track digital tape recorders, or 8-track hard disk recorders, such as Alesis ADAT, ADAT-XT, Alesis M20, Akai DR8, Akai DD8, Fostex D-90, or Fostex CX-8. • Four ADAT optical cables • ADAT sync cable See "Installing Option I/O Cards" on page 218 for MY8-AT installation instructions. Wordclock Configuration For digital audio transfer, digital audio devices must be wordclock synchronized (see "About Wordclocks" on page 206). In this example, digital multitrack recorder A is wordclock master, while digital multitrack recorder B, the 01Vs, and DAT recorder are wordclock slaves. Digital multitrack recorder B derives its wordclock from the sync connection with recorder A. The 01Vs derive their wordclocks from their Option I/O digital inputs, and the DAT, from the Digital Stereo Coaxial Out of the 01V. The wordclock frequency, which is the same as the sampling rate, is set when the digital multitrack tape is formatted or first recorded. For digital recording from the DAT recorder to the digital multitrack recorders, the DAT recorder must be configured as wordclock master and the 01Vs and digital multitrack recorders as wordclock slaves. The sampling rate will be the same as that used when the DAT tape was recorded. If a CD player is used instead of the DAT, the sampling rate will be fixed at 44.1 kHz, the industry-standard for music CDs. System Notes • The digital IN and OUT connectors on the MY8-AT cards are connected to the digital multitrack recorders using ADAT optical cables. • On Alesis ADAT 8-Track Digital Audio Recorders, use the DIGITAL IN button to select the optical digital input. • Although the 01V is a four-bus mixer, a combination of bus outs, aux sends, and channel direct outputs can be assigned to the digital outputs for eight-track simultaneous recording. See "Assigning Option I/O Digital Outputs" on page 219 for more information. 01V-Owner's Manual
