Frequently Asked Questions - Redbox RB-SYA Sonifex
What is the Sonifex Redbox RB-SYA used for?
The Sonifex Redbox RB-SYA is a digital audio format converter that converts between AES/EBU and S/PDIF signals with asynchronous sample rate conversion. It is ideal for interfacing professional and consumer digital audio equipment.
How do I connect the RB-SYA to my equipment?
Connect the digital output of your source device to either the AES/EBU (XLR) or S/PDIF (RCA) input. Then connect the corresponding output to your destination device. Select the appropriate input and output connectors based on your gear. The RB-SYA automatically detects the signal and performs necessary sample rate conversion.
Does the RB-SYA support sample rates above 96 kHz?
The RB-SYA supports sample rates from 32 kHz to 96 kHz. If your equipment operates at higher rates, such as 192 kHz, this unit is not suitable for direct conversion; you would need a different model.
Can I use the RB-SYA to convert both ways simultaneously?
The RB-SYA is a bidirectional converter but only in one direction per operation. It can convert from AES/EBU to S/PDIF or from S/PDIF to AES/EBU. The output mirrors the selected input format.
Is an external power supply required?
Yes, the RB-SYA operates with an external 12V DC power adapter. The adaptor is included with the unit. Always use the supplied adapter to ensure correct voltage and polarity.
How can I tell if the unit is receiving a valid signal?
The RB-SYA features LED status indicators. The 'Power' LED lights when the unit is powered. The 'Input Lock' LED illuminates when a valid digital signal is detected on the input, and the 'Output Lock' LED shows that the output is active.
Can I mount the RB-SYA in a rack?
Yes, the RB-SYA can be mounted in a 1U rack using an optional Sonifex Redbox rack mount kit. This allows you to install multiple Redbox units side by side in a standard 19-inch rack.
What is the maximum cable length for the inputs?
For AES/EBU (balanced XLR) connections, cable runs of up to 300 feet (approx. 100 meters) are typically possible. For S/PDIF (unbalanced RCA) connections, keep cables shorter than 10 meters to avoid signal degradation.
How do I clean and maintain the RB-SYA?
To clean the unit, use a dry, lint-free cloth. Avoid using liquids or sprays. Ensure the connectors remain free of dust and debris. Periodically check the power adapter and cables for any signs of wear.
What should I do if there is no output signal?
First, check that the Input Lock LED is lit; if not, the source signal may be missing or invalid. Verify the selected input and output connectors. Ensure the output device is set to the correct input. If the problem persists, try a different sample rate or consult the manual's troubleshooting section.
