input distortion. Make sure you have the proper signal levels set on the

inputs to the Delta R-BUS. If you find that you are still clipping, you will

need to turn down the audio at the source.

Possible Cause 2: If you are recording from the S/PDIF input, but

you have the Delta R-BUS’s master clock set to something other than the

S/PDIF input, you are recording an out-of-sync S/PDIF stream. This can

result in lost or bogus samples being recorded.

Possible Cause 3: If you are recording from the R-BUS input, but

you have the Delta R-BUS’s master clock set to something other than the

R-BUS Clk, you are recording an out-of-sync R-BUS stream. This can

result in lost or bogus samples being recorded.

Possible Cause 4: Your application software may not have the proper

audio buffer sizes set. Each software application handles this differently, but

typically there is somewhere in the software’s setup to set the size of the

playback and recording buffers used by the application. Some applications

also require you to run a card calibration (sometimes called "profiling") the

first time you use the software with a new audio card.

Possible Cause 5: Some accelerated graphics cards use excessive

amounts of system bandwidth, preventing the recording buffer of an

audio card from keeping up with demand. This can cause clicks in the

recording. Reducing or turning off the graphics card’s graphics

acceleration feature often resolves this problem. In Windows, the level of

graphics acceleration is accessed from Start |Settings | Control Panel |

System | Performance | Graphics.

Problem: I’m getting some pops and clicks in my monitoring signal,

even when my system is idle.

Possible Cause: If the S/PDIF input is not muted in the monitor

mixer, and you have the Delta R-BUS’s master clock set to something

other than the S/PDIF input, you are monitoring an out-of-sync S/PDIF

stream. This can result in lost or bogus samples being recorded. This can

also occur when using the R-BUS input without “R-BUS Clk” selected as

you master clock.

Problem: The sound from the monitor mixer is muffled. It sounds as

if it were running through a mixer with the treble control turned all the

way down!

Possible Cause: The current Delta R-BUS sample rate is too low. The

monitor mixer is a digital device that runs at the current sample rate of the

Delta R-BUS board. The frequency response of the mixer is roughly one-half

of the sample rate. There is no way to prevent this lost frequency response

while playing back or recording at a low sample rate. However, it may be

prevented when the system is idle. See the "CODEC SAMPLE RATE"

paragraph of the section ‘Hardware Settings Page’ for more information.
