TIPS

If you receive an "invalid sample rate" error message, check the

connections between the WavePRO interface and the audio

equipment. Also, make sure the sample rates all match up.

If you experience audio drop-outs and you are using the RCA jacks

for SPDIF, make sure that the cable you're using is 75-ohm cable

(video quality) and *not* standard audio cable that's used in home

stereos.

Word Clock and external clocking

The "heartbeat" of digital audio gear is determined by an electronic

clock. Due to design and manufacturing tolerances, the internal

clocks within different pieces of digital audio gear will vary by small

percentages.

To provide flawless data exchange and to prevent timing drift

between tracks, it's necessary that the digital audio gear share the

same clock. In other words, a piece of equipment is designated as the

"master" and it uses its own internal clock. The other pieces of gear

are then set to be the "slave(s)", using an external clock.

When a SPDIF or ADAT option card is added to a WavePRO interface,

the interface is enhanced to support external clocking.

The clock can be transmitted between the gear by the digital audio

interface cable (SPDIF or ADAT). In other words, the clock is

embedded in the digital audio signal.

Additionally, a Word Clock feature is included with the WavePro ADAT

option card. Word Clock is shared between digital audio gear via a

coaxial cable connected to the Word Clock input and output BNC

jacks.

NOTE: When you are using a WavePRO interface to receive

(record) digital audio data from another piece of

gear, it's necessary that the WavePRO interface be set

to use external clocking. The WavePRO card will act

as a "slave" to the other digital audio equipment.
