Adjusting and Verifying Audio with DSP

21

Instruction Manual – BCS Basic Control Structure Protocol

Adjusting Balance 

Note:

 The examples below assume a default level which is audio or includes audio. If the default 

level does not include audio, you must enter a level that includes audio. 

Balance commands tell the output to pan to the left or to the right by a percentage of the total range. 
Positive percentages pan to the right, and negative percentages pan to the left.

To adjust balance for an output:

1.

Enter the balance command below. Replace the “

#

”s with the output number and replace “

^^^

” 

with the percentage.

CO#P^^^T

Balance Examples 

Adjusting Tone 

Tone bands (filters) for bass and treble can be adjusted to a specific decibel level at anytime during 
normal operations. Each tone band has a range of -12 dB to +12 dB. Further frequency adjustments can 
be made to each output by adjusting the equalization bands (see page 22).

To adjust the gain of a tone band (filter) for an output:

1.

Enter the tone command below. Replace the “

#

”s with the output number and tone band (filter) 

number and replace “

^^^

” with the decibel level. (Enter the decibel level as an integer number 

representing the desired decibel value multiplied by 10, e.g., -5.0 dB is entered as -50.)
