In order to match the BAD4 delay, you must set two jumpers. Jumper A adds a raw delay of 21 samples

and Jumper B switches to a longer delay filter of 45 samples. Both combined add to the 66 samples of

delay necessary to match BAD4.

NOTE: All ADCs and DACs have a delay which is inherent in their conversion from high speed sigma-

delta data to PCM data. There is digital signal processing involved that requires a low pass digital filter.

Each type of filter has its own sound and its own delay. When in doubt, just go with the default setting.

Here are the Jumpers (JP2) and their effect. To match BAD4, jumper A and B.

No Jumper set – 7 samples of delay, default short filter

Jumper A – 21 samples of delay (just adds delay)

Jumper B – 45 samples of delay, long filter

Jumper C – 16 samples of delay, alternate short filter

Jumper D – High pass filter by-pass (not recommended)

Default Jumper Settings, 7 samples of delay

BAD4 matched, 66 samples of delay

In addition to the low pass filter settings, we allow the user to by-pass the high pass filter (low cut filter).

The high pass filter is normally used to cut out any DC offset that is in the analog audio. The high pass

filter has a very low cutoff point. By-passing the high pass filter will give you slightly better low end, but

it can have negative side affects if not used carefully. If you plan on processing the audio data with

plug-ins or boosting the signal in any way, the DC offset can increase and cause undesirable clicks and

pops in the audio, especially if auto fade in/out is not enabled on playback.

If you are using the BAD8 as just a record and playback device (for example, in mastering) or if you plan

to use a high pass filter plug-in, experimenting with the high pass filter by-pass might be worth checking

out. Again, proceed with caution.
