Page 3: Introduction
The SRC9624 supports a range of sample rates and 16-, 20-, and 24-bit word sizes. Using asynchronous conversion algorithms, it handles any input rate from 30 kHz to 100 kHz, in- cluding varispeed and common pull-up and pull-down rates. -
Page 4: Operator Safety Summary
Identifies information that needs extra emphasis. Supplies extra information to help you to better use the product. Caution Identifies information that, if unheeded, may cause damage to the Lucid product or other equipment in your system. Warning Identifies information that, if ignored, may be hazardous to your health or that of others. - Page 5 There are no user serviceable parts inside the SRC9624. In case of failure, refer all servicing to the factory. Servicing is required when the SRC9624 has been damaged in any way, such as when a power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

The WORD IN BNC connector accepts word clock. This input does not terminate. If the SRC9624 is the last unit in a chain, you must use a tee connector at the input along with a 75- ohm terminator. The input accepts sample rates from 30 kHz to 100 kHz. - Page 7 Mode Selection Each portion of the SRC9624 uses three-position toggle switches to move the selection up or down. For the inputs, if the digital receiver does not achieve lock (no signal, or bad signal), the INPUT STATUS LEDs will not illuminate. Once the input locks, the status LEDs display the status information contained in the input signal.
- Page 8 or non-audio (e.g., AC3). These bits are fed through the unit to the output. If the selected input is not present, the input A source LED flashes. Input B Source The INPUT B switch selects the desired source connection for Input B, either XLR, coaxial, or TOSLINK.

COAXIAL (AES3-S/PDIF) BNC* connector. Carries S/PDIF-AES3 signal. AES3 XLR-male connector. Carries AES3 signal. 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. -

- Page 13 Simply stated, you can use the SRC9624 to convert digital audio signals to sample rates above 50 kHz, and transmit them via ordinary AES3 capable wiring, overcoming the distance limita- tion at high bit-rates.
- Page 14 A/D converter’s word clock input from the recorder’s word clock signal. But what if the A/D converter doesn’t have a word clock (external sync) input? You use the SRC9624 to reclock the signals to the recorder’s word clock.
- Page 15 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.
