Unbalanced L & R analogue outputs. These carry the same audio signal as the main outputs (1) above, but in unbalanced form on phono connectors (RCA jacks) at a nominal level of -10dBu. Output level is calibrated internally to be +8dBu from a maximum (digital clip) PCM signal level of 0dBFS. Output impedance is 47Ω.
AES/EBU out. This provides a two-channel AES/EBU digital output conforming to AES3-2003. The connector is an XLR3M, output impedance 110Ω.
S/PDIF Coaxial digital output. A 2-channel“semi-pro” digital output conforming to the IEC60958-4 is available at this connector. Transmission of CD PQ codes and CD Text data are enabled in the S/PDIF data stream; the signal is otherwise the same as that available at the AES/EBU connector (8).
Note that the channel status bits denoting whether the digital outputs are “Pro” or “Consumer” may be set via the menu system (Record > Digital Output Format), and that this setting applies to both the AES/EBU and S/PDIF digital outputs.
Also note that the S/PDIF output is used in Multi-Machine modes to pass audio, clock and CD Text data between units.
S/PDIF Optical digital output. Standard TOSlink connector carrying the same signal as (9) above, in optical form. Use a standard optical TOSlink cable of not more than 3m. length.
RS232 Link Input connector. The CDR-882 can be fully controlled remotely via RS232 serial commands. Pinout, port parameters and an abridged command set can be found at page 13. This port permits one or more (see
(12)below) CDR-882s to be controlled from a dedicated computer with appropriate software, or by a proprietary external control system (Crestron, AMX, etc.). A “crossed” cable (i.e., one with transmit and receive pins cross- connected) should be used when controlling the CDR-882 from an external control system. A D9M connector is used.
RS232 Link Output connector. This allows control information to be passed from Master to Slave units in Multi-Machine mode. It also allows multiple CDR-882s to be controlled from a single RS232 controller.
The link connector is a D9F. The pinout is the same as the RS232 input, except that the Data transmit and receive pins (2 & 3) are reversed. Thus when “daisy-chaining” CDR-882s, “straight” cables must be used, in which all connections between machines are “pin-to-pin”. Note that in multi-machine modes, the “master” CDR-882 generates control data for the connected “slave” units.
Note that the RS232 link connector only passes control data, not audio. In multi-machine modes, the audio signals need to be distributed to multiple CDR-882s separately using S/PDIF interconnections. See page 42 for full details of Multi-Machine operation.
Parallel remote control connector. The CDR-882’s basic transport commands can also be implemented by volt-free contact closure at the pins of this connector (a D9F). Five of the pins are designated as inputs, three as outputs (tallies). The functions controlled by each of the inputs are user-definable via the menu system. The source of the tally outputs is similarly definable. Full information, including pinout, is available at page 51. Assignment of inputs and outputs is performed via the menu system; see page 36 for full details.
Word Clock input. An input for an external 44.1kHz digital audio word clock is provided on a BNC socket. The input impedance is either 75Ω or high-impedance, set by the termination switch adjacent to the connector.
Word clock selection and routing is done via the menu system; see sections page 21 & page 31.
Keyboard input. A PS/2 connector is available on both front and rear panels for the connection of a standard QWERTY keyboard. The CDR-882 supports CD Text with audio CDs in both record and replay modes, and connection of a standard keyboard provides a rapid means of entering textual data to be displayed on the front of suitably-equipped CD players (including the CDR-882).
AC mains input. The CDR-882 is powered via a standard IEC connector. The CDR-882’s design includes a universal power supply and will accept all AC mains voltages from 100 to 240V, 50 to 60Hz.
