User manual TASCAM TM-D1000 PART 1

[. . . ] 1 - TM-D1000 Operations Manual Congratulations on your purchase of the TM-D1000. This high-quality digital mixing console allows you to produce crystal-clear multitrack recordings and to mix them to a digital stereo mastering machine. We do not expect you to read the Reference Manual from cover to cover, but if you take the time to read through this Operations Manual, this will be repaid in terms of future familiarity with the unit. Since the TM-D1000 is a complex unit, with many software features that are not immediately visible from the front panel, we suggest, however, that you make yourself familiar with at least the contents of the main reference manual, so that you can find the answers you need when you have questions. [. . . ] If this is already shown on the bottom line of the display, there is no need to press ENTER. 4 5. 5 Using digital effect returns An increasing number of digital effect units allow you to send signals to them, and to input their returns in digital format. To select the EFFECT or AUX return as a digital input: Turn the DATA ENTRY knob until the bottom line of the display shows Digital In A2. 1 2 Press and hold down the SHIFT key and press the OPTION key. Turn the DATA ENTRY knob until the bottom line of the display shows Setup, and press ENTER. If the optional IF-TD1000 Digital I/O Board has been installed, you will also have the options of selecting the input from the second TDIF-1 port and from the second (B) digital input. If channels 7 and 8 are selected, the third (C) digital input will also be available. NOTE It is possible for you to assign the digital input to more than one input channel (including the Effect and Aux return busses). All controls assigned to the digital input will be enabled. 5 Remember to assign the input to the appropriate busses. Push the DATA ENTRY knob to enter the assignment screen, and assign the return to the L-R, 1-2 or 3-4 busses. 2. If the optional IF-TD1000 Digital I/O Board has been installed, you will also have the option of selecting the input from the second (B) digital input. Again, if channels 7 and 8 are being used, Digital input (C) can also be used. 15 TASCAM TM-D1000 Operations Manual 6 - Word synchronization When you have a digital audio setup, it is most important that all equipment in the setup shares the same word clock. This is not at all related to timecode synchronization, but refers to a digital signal at the sampling frequency which marks the beginning and the end of digital data "words". If this clock is not present, or is distorted, the resulting signals passed between different pieces of equipment will not be synchronized, with audible noise which may even be high-frequency noise which will damage amplifiers, speakers, etc. The proper setup of a word clock in a digital audio system is therefore essential. We refer to devices as word clock masters or slaves, depending on whether the word clock is originated by them, or received from another device. If the TM-D1000 is configured as a word clock master, you cannot use any varispeed facilities on any digitally connected devices (multitrack systems, CD players or DAT recorders). 1 2 Press and hold down the SHIFT key and press the OPTION key. Turn the DATA ENTRY knob until the bottom line of the display shows System and press ENTER. Turn the DATA ENTRY knob until the bottom line of the display shows Master Clock Select, and press ENTER: Clock Select 3 Master Internal[44. 1 k ] NOTE There must be one, and only one, word clock master in a system. Furthermore, each device in a digital audio setup must be set up to work at the same sampling frequency. You cannot have a system in which a CD player (with a fixed sampling frequency of 44. 1 kHz) can be used to provide digital audio signals to a recorder or mixer whose sampling frequency has been set to 48 kHz. The standard stereo digital signals (AES/EBU and SPDIF) that are marked as "DIGITAL" from DAT recorders, CD players, etc. carry their own clocks as part of the signal. Most "domestic" CD players and DAT recorders will expect to be the word clock master when playing back, and (in the case of a DAT recorder) when recording, will become a word clock slave. Professional equipment (DAT recorders, CD players, digital multitrack and hard disk recorders, and digital mixers such as the TM-D1000) can usually be configured to act as either a word clock master or slave. 4 5 Use the data entry knob to choose either 48 kHz or 44. 1 kHz as the internal clock. Make sure that any other devices which can accept external word clocks are set to do so. NOTE The TDIF-1 standard allows any DTRS or other TDIF-1-equipped device to take its clock through the TDIF-1 connector. [. . . ] This sub-menu is available from the Setup options, and appears as follows: Ch7-8 Route1 Target In C? Digital 1 2 3 The wristpad below the faders should be unscrewed before mounting the TM-D1000 in a rack. Attach the two rack mounts to the TMD1000 using the five screws (provided) on each mount. Fit the TM-D1000 into the rack, allowing enough space at the top for cables to be fitted to the connectors. Use the data entry knob to choose between Digital In C and Analog. As well as the additional stereo digital inputs, the IFTD1000 Digital I/O Board also provides another TDIF-1 connector (TDIF-1 B). [. . . ]
