Apache Quote
“The Apache is the ideal device for the majority of lightpipe-based setups and an obvious choice. It’s a great time-saver and a worthy addition to your digital world.

Apache Frequently Asked Questions
- How do I route 96kHz audio in Apache?
- I saw the statement that Apache re-clocks the ADAT optical signals, but that sounds like the signal would then not be in sync with the clock master (because it's now clocked by Apache). Why don't I have to set Apache to internal or external clock?
- If I patch an input to several outputs, does the signal become degraded or distorted?
- Can Apache route several inputs to a single output?
- How do I select an Apache input to serve as the clock master for the Apache outputs?
- Can Apache convert between ADAT-format and TOSLINK-format signals?
- Can I use multiple Apaches together?
- What's the longest length optical cable that can be used with Apache?
- Can Apache pass S/MUX, MR-X, PAQRAT, or other variations of ADAT optical signals?
How do I route 96kHz audio in Apache?
Any of the Apache optical ports can transmit 96kHz audio. You just use twice as many optical ports as you use for 48kHz audio. For example, to route 8 ADAT channels at 96kHz from a digital mixer to a hard disk recorder, you''d connect two optical cables from the mixer (to Apache inputs 1 & 2 for example) and two optical cables to the recorder (from Apache outputs 5 & 6 for example), and then patch input 1 to output 5, and input 2 to output 6.
I saw the statement that Apache re-clocks the ADAT optical signals, but that sounds like the signal would then not be in sync with the clock master (because it's now clocked by Apache). Why don't I have to set Apache to internal or external clock?
Apache's input circuits lock to the clock that''s embedded in the incoming lightpipe stream. Any lightpipe outputs that are patched from that input are themselves clocked with the recovered input clock, and are therefore in sync with the original source.
If I patch an input to several outputs, does the signal become degraded or distorted?
No. Whether the input is patched to one output or to all 12, the same clean signal is delivered through each output.
Can Apache route several inputs to a single output?
No. Combining multiple inputs is a mixing function. Apache doesn''t mix or alter the optical signals.
How do I select an Apache input to serve as the clock master for the Apache outputs?
You don't! Each Apache input is separately re-clocked and transmitted to its patched outputs. In effect, whatever is the clock source of the Apache input becomes the clock source of its patched outputs. In terms of clocking, Apache acts just like a set of optical cables.
Can Apache convert between ADAT-format and TOSLINK-format signals?
No. Apache is only for routing signals, not for converting signal formats.
Can I use multiple Apaches together?
Yes. You can cascade any number of Apaches and use them together. See "Cascading Apaches" in the User's Guide for details.
What's the longest length optical cable that can be used with Apache?
Apache has been tested successfully with many devices, using optical cables up to 10 meters (33 feet) long.
Can Apache pass S/MUX, MR-X, PAQRAT, or other variations of ADAT optical signals?
Yes. Apache recognizes, re-clocks, and faithfully passes any information that is encoded in an ADAT optical signal, including these alternative formats.
