Troubleshooting & Frequently Asked Questions

There are little clicks and pops, like some type of static, when using

the MaxxBCL.

This is nearly always a synchronization issue. Make sure that your Sync selec

tion is proper. If you are using digital inputs, then you should select (D) for

Digital sync, to lock to the selected digital input. This gives the lowest jitter

performance and should solve any clock problems. If for some reason you

have the Sync set to Internal while using a Digital input, it is nearly guaran-

teed that you’ll have clicks and pops.

What is true uncorrelated stereo dither?

Uncorrelated simply means that the items being compared are separate

and distinct and have no relation to each other. In this case we’re talk

ing about a random signal, unlike the pseudo-random or periodic signals

of some technologies, which by deﬁnition cannot be truly uncorrelated.

What’s the big deal? Stereo image is the bottom line. If you take Left and

Right channels and take a signal that is similar, or worse yet, exactly the

same (such as mono dither, as some popular “ﬁnalizing” products have),

then add it to both channels, you have made them more similar at low lev-

els of detail than they were. This causes these details to be more alike, and
