If you were to set the output rate to 48k, the signal will actually be sent at a 24 kHz frame rate, a format which is not generally used. Input A Source The INPUT A switch selects the desired source connection for INPUT A. The INPUT A STATUS LEDs monitor certain bits in the digital audio stream--pro or consumer, and audio 5 or non-audio (e. g. , AC3). Input B Source The INPUT B switch selects the desired source connection for Input B, either XLR, coaxial, or TOSLINK. The INPUT B STATUS LEDs will monitor certain bits in the digital audio stream--pro or consumer, and audio or non-audio (e. g. , AC3). Output Sample Rate The OUTPUT SAMPLE RATE switch determines the sample rate of the digital audio output on both outputs A and B. For word clock input, AES11 Sync input and Input A input, the selected sync source's LED will flash if a valid clock signal is not present on that connector. For the internal clock frequencies, the selected sync source's LED illuminates. Settings of 20-bit or 16-bit indicate that the output signal has been dithered, using triangular PDF dithering, to these word lengths. 6 PRODUCT DESCRIPTION - SRC9624 FRONT PANEL SECTION 4 Feature ROUTING Description LEDs indicate the current signal routing. Independent Distribution 96 kHz Dual AES (source) Input A drives Output A, Input B drives Output B. This could be a sync-only signal or it could be a digital audio signal (the audio portion is ignored). WORD IN AES11 Digital Output A and B The two sets of outputs are driven separately and there is no interaction between the connectors. Signals appearing at these outputs vary according to the setting of the ROUTING selector switch. OPTICAL (S/PDIF) AES3 Digital Input A and B The digital inputs are all separate; any or all may be connected. The actual connector used as the signal source depends on the setting of the INPUT A SOURCE or INPUT B SOURCE selector switches. Long cable runs require 110-ohm shielded twisted-pair cable. *BNC to RCA adapters are included with the SRC9624. Use these adapters if you are connecting to equipment with RCA/coaxial connectors. TOSLINK connector. Long cable runs require 110-ohm shielded twisted-pair cable. COAXIAL (AES3-S/PDIF) BNC* connector. Carries S/PDIF-AES3 signal. 8 USING THE SRC9624 SECTION 5 This chapter discusses operation of the SRC9624.

[. . . ] The WORD OUT signal always reflects the sample rate of the output converters. If the Output Sample Rate switch is set to the WORD CLOCK position, then the WORD OUT is a thru connection from WORD IN. Remember that WORD IN is a bridging connection; if the SRC9624 is the last unit in a chain, you must terminate the input with a 75-ohm resistor (use a tee-connector). If you need to chain multiple WORD IN connectors, use tee connectors and remember to terminate the last unit in the chain. [. . . ]
