DSPB23

Graphical User Interface Software

 
Acoustic Technologies DSPB23 Graphical User Interface Software provides complete control of the DSP System embedded within the QDC42.dsp Multi Channel Amplifier.
  
 
The Main Screen allows access to each of the functional processing blocks. A Menu Panel allows communication with the QDC42’s hardware, disk based file operations and several ancillary functions.   
 
 
DSPB23 MAIN SCREEN
 
The DSPB23 digital signal processing system provides comprehensive audio processing.
  The PC based graphical user interface provides a familiar programming environment for the installation professional.
 
The Main Screen allows access to each of the functional processing blocks.  A Menu Panel allows communication with the QDC42’s hardware, disk based file operations and several ancillary functions.
 
The Main Screen allows the naming of the Channel’s Input and Outputs and provides a text Comment Box suitable for documentation purposes.
 
The DSPB23 provides 7x 2nd Order PEQ Filters / Channel with 13x filter topologies available for each PEQ, selected from a drop down selector box.
 
 
DSPB23 PARAMETRIC EQUALIZATION
 
 The DSPB23 provides 7x 2nd Order PEQ Filters / Channel with 13x filter topologies available for each PEQ, selected from a drop down selector box. Available filter types are:
 
Parametric Constant Q Parametric Adaptive Q
Shelh Low 6dB Shelf High 6dB
LP Butterworth HP Butterworth
Band Pass Stop Band
All Pass 1 All Pass 2
Low Pass Q High Pass Q
IIR Coefficients Bypass

Filter adjustments are made with value sliders, text boxes and scroll buttons.   The combined response of each channel’s equalization, both magnitude and phase, is graphically displayed.
 
The DSPB23 provides 2x 2nd Order Crossover Filters / Channel. <BR> The Crossover can be configured to provide either a <BR> 2nd Order LPF/HPF Crossover.
 
 
DSPB23 CROSSOVER
 
 The DSPB23 provides 2x 2nd Order Crossover Filters / Channel. The Crossover can be configured to provide either a 2nd Order LPF / HPF Crossover, or the filters can be combined to provide a single 4th Order LP or HP Filter section. Available filter types are:
 
Butterworth Linkwitz-Riley
Bessel Butterworth
 
  Crossover adjustments are made with a drop down selector box, text boxes and scroll buttons.   The combined response of each channel’s Crossover, both magnitude and phase, is graphically displayed.
 
The DSPB23 provides Gain Control, Polarity Invert<BR> and Mute for each channel..
 
 
DSPB23 OUTPUT GAIN CONTROLS
 
The DSPB23 provides Gain Control, Polarity Invert and Mute for each channel.
Channel Gain is variable over a 36dB range, adjustable in 0.1dB increments via a value slider or text box.
Buttons are used to select the Polarity Invert and Channel Mute functions.
The DSPB23 provides a continuously variable Delay Time for each channel. The Delay Time is variable from 0.00mSecs to 3.40mSecs in 0.02mSec increments.
 
 
DSPB23 OUTPUT DELAY
 
 The DSPB23 provides a continuously variable Delay time for each channel. The Delay time is variable from 0.00mSecs to 3.40mSecs in 0.02mSec increments via a value slider or text box.
 
Alternatively, the DSPB23 allows the relative distance between acoustic centres to be entered.  Clicking the [Auto Align] button computes the required Delay to physically align the acoustic centres.
 
The DSPB23 provides highly flexible Dynamics control by offering a Limiter or Compressor for each output channel.
 
 
DSPB23 DYNAMICS PROCESSOR
 
 The DSPB23 provides highly flexible Dynamics control by offering a Limiter or Compressor for each output channel.
Adjustable parameters are:
 
Threshold Knee
Compression Ratio Noise Gate Level
Attack (dB/Sec) Release (dB/Sec)
Hold Time (mSecs)  

 A graphic display of the Dynamics transfer function is shown.
 
The Final Response Panel graphically displays the combined response of the entire DSPB23 Preset.
DSPB23 FINAL RESPONSE
 
 The Final Response Panel graphically displays the combined response of the entire DSPB23 Preset.  Both magnitude and phase response plots for each channel are provided.
 
In addition the DSPB23 Software allows the direct import of the SPL and Phase response of each of the loudspeaker system’s components, allowing the response of the entire processing, amplifier and loudspeaker system to be accurately modelled.
