TASCAM IF-AE8 3 IF-AE8 Digital Audio Converter The TASCAM IF-AE8 provides a convenient way of exchanging digital audio data between TDIF-1-equipped devices, such as DTRS recorders, and AES/EBU devices. A single TDIF-1 connector carries eight channels of digital input and output. Four XLR-type connectors accept four two-channel input signals in AES3-1992 format, and another four XLR-type connectors output four two-channel input signals in AES3-1992 format. The word synchronization is selectable, using a front panel switch, from any of the four AES/EBU inputs, from the TDIF-1 source, or from an external independent word clock source. The word clock source can be used as the clock source for sampling frequency conversion. All standard rates (32 kHz, 44.1 kHz and 48 kHz) are supported for input and output. If sampling frequency conversion is carried out, the IF-AE8 will generate an independent clock signal, based on the target frequency, so that other units may be synchronized to it. The signal transmitted from the AES/EBU outputs can be selected to come from the AES/EBU input signals or from those received at the TDIF-1 connector, using a front panel switch. Format conversion is possible with up to 24-bit data with TDIF digital audio format, and 20-bit with AES3-1992 format data if no sample rate conversion is performed (20-bit data for both formats if the sampling frequency is converted). The digital audio output format is selectable as either professional or consumer format using a front panel switch. 1 Front panel 1 POWER switch and indicator Push the POWER switch once to turn on power, and again to turn it off. The POWER indicator lights when power is supplied to the IF-AE8. high-frequency noise generated by word clock incompatibilities. 4 DIGITAL OUT switch and indicators This switch allows you to select the source of the digital audio signals that are output from the DIGITAL I/O (AES/EBU) OUTPUTS (1/2, 3/4, 5/6, 7/8) 7. The source can either be the signals received at the AES/EBU inputs 8 (DIGITAL IN) or at the TDIF-1 connector 9. If the TDIF-1 option is selected, the eight channels of the TDIF-1 audio are mapped on a "one-to-one" basis to the eight AES/EBU audio output channels. If the DIGITAL IN option is selected, the input data received at the AES/EBU ports is passed through to the corresponding output ports. However, it may be passed through the sample rate conversion before reaching the output ports. 2 LOCKED indicator When a valid clock signal is received at the selected clock source, this indicator will light. 3 CLOCK switch and indicators This switch allows you to cycle between the six possible clock sources for the IF-AE8: the WORD SYNC IN A connector, the DIGITAL I/O (TDIF-1) 9 connector, or any of the four two-channel AES/EBU connectors (DIGITAL I/O (AES/EBU) INPUTS (1/2, 3/4, 5/6, 7/8) 8), as shown by the indicators to the right of the switch. WARNING There should usually never be more than one word clock signal in a digital audio system. If there are not, at worst, damage may occur to speakers, amplifiers, etc. as a result of 5 DIGITAL OUT FORMAT switch and indicators The format of the digital audio output from the AES/EBU output connectors 7 may be either professional AES3-1992 format (PRO) or 4 TASCAM IF-AE8 IF-AE8 Digital Audio Converter CONSUMER IEC-60958 TYPE II format. The electrical characteristics of the output connectors remain the same, regardless of the data format selected. the clock source for the converted signal. The DIGITAL I/O (TDIF-1) 9 cannot be used as the clock source for conversion, though both it and the DIGITAL I/O (AES/EBU) OUTPUTS (1/2, 3/4, 5/6, 7/8) 7 can be the destination. 6 Fs RATE CONVERT switch and indicators This switch provides two settings: THRU-1 and CONVERT. When the switch is set to THRU-1, the input signals (selected using the DIGITAL OUT 4 switch) will be output from the AES/EBU output connectors at the same frequency. When the switch is set to CONVERT, the input signals will be output at the sampling frequency of the clock source selected with the CLOCK switch 3. Note that any of the DIGITAL I/O (AES/EBU) INPUTS (1/2, 3/4, 5/6, 7/8) 8 may be selected as NOTE The AES/EBU unit which provides this clock source may be different from the unit which provides either the input or the output signals. You must, however, make sure that word clock synchronization is correctly carried out. 2 Rear panel 7 DIGITAL I/O (AES/EBU) OUTPUTS (1/2, 3/4, 5/6, 7/8) These balanced connectors output digital audio data in AES3-1992 professional or in consumer format, depending on the selection made with the DIGITAL OUT FORMAT switch 5. The content of the data depends on the setting of the DIGITAL OUT switch 4. The sampling frequency of the output data depends on the setting of the Fs RATE CONVERT switch 6, and the currently-selected clock source 3. The signals received at this connector may be selected as the word clock source using the CLOCK switch 3. WARNING Note that you should always use genuine TASCAM cables, or cables which have been approved for use with TDIF-1 interfaces by TASCAM. Although these cables appear similar to certain types of computer cables and use similar connectors, the cables themselves are very different, and the different electrical characteristics of the cables can cause damage to the equipment connected with the wrong cables. If the use of cables other than TASCAM cables causes or results in damage, the warranty is voided. 8 DIGITAL I/O (AES/EBU) INPUTS (1/2, 3/4, 5/6, 7/8) These balanced connectors accept digital audio data in AES3-1992 format. The signal received at any of these connectors may be selected as the clock source for the IF-AE8 using the CLOCK switch 3 A WORD SYNC IN The BNC connector accepts a word clock signal from an external source. It may be selected as the word clock source for the IF-AE8 using the CLOCK switch 3. TASCAM IF-AE8 5 9 DIGITAL I/O (TDIF-1) Use this connector to connect a suitably-equipped TDIF-1 digital audio unit (e.g. a DTRS recorder or a TASCAM digital mixing console). IF-AE8 Digital Audio Converter B WORD SYNC OUT This BNC connector outputs a word clock based on the word clock source selected using the CLOCK switch 3. The mastering system takes its word clock through the AES/EBU data from the appropriate DIGITAL OUT of the IF-AE8. The DIGITAL OUT FORMAT switch 5 is set to PRO, so that the data coming from DAT 2 is converted to professional format data. NOTE This may or may not be the same as the clock received at WORD SYNC IN A and retransmitted through WORD SYNC THRU C. However, it is always the word clock selected using the CLOCK switch 3. 4 Specifications XLR-type, balanced outputs Switchable between professional (AES3-1992) and consumer (IEC-60958 TYPE II) formats XLR-type Auto-detect professional (AES3-1992) and consumer (IEC-60958 TYPE II) formats Conforms to TDIF-1 specification Any of AES/EBU DIGITAL INPUTS, TDIF-1, or WORD SYNC IN (front panel selection) Lights when valid clock source received at selected input 48 kHz, 44.1 kHz, 32 kHz 48 kHz, 44.1 kHz, 32 kHz, taken from CLOCK source Up to 24 bits TDIF-1,(20 bits with Fs conversion), 20 bits AES3-1992 75 75, reproduces clock selected from front panel switch 75 (auto terminating), echoes clock at WORD SYNC IN 428 x 48 x 194.8 (mm) 16.9 x 1.9 x 7.7 (in.) 2.6 kg (5.7 lbs) 120V (UL), 230V (Europe, Australia) 6W Rack mounting kit DIGITAL OUTPUTs (1­2, 3­4, 5­6, 7­8) DIGITAL OUTPUT output format C WORD SYNC THRU This BNC connector echoes the word clock signal received at WORD SYNC IN A.

DIGITAL INPUTS (1­2, 3­4, 5­6, 7­8) DIGITAL INPUT input format 3 Application example D IGITAL I/O (TDIF-1) Clock source In this example, the original material (from two sources) has been mixed to DAT, and has been produced in both professional and consumer formats, and at both 44.1 kHz and 48 kHz sample rates. The final master data will be recorded and coded on a computer-based system, with an AES/EBU interface. LOCKED indicator Valid input Fs rates DAT 1 AES/EBU audio in 48 (C) 44.1 (P)* Valid output rates Word length DAT 2 IF-AE8 44.1(P) WORD SYNC IN WORD SYNC OUT Mastering system WORD SYNC THRU Here, the two DAT recorders are fed through the IF-AE8. Since the resulting data will be at 44.1 kHz, the DAT playing back the material at 44.1 kHz (DAT 1) is selected to act as the clock master. Since the TDIF-1 I/O is not used here, the DIGITAL OUT switch 4 is set to DIGITAL IN. The word clock is therefore derived from this, and used to resample the 48 kHz material from DAT 2, and the Fs RATE CONVERT switch 6 is set to CONVERT.
