DSP Audio Processor

● 9.3.4 LED Indicators

 

   Each input and output channel has a 4 segment LED array for audio level display, ranging from  

   -48dB (SIGNAL) through clipping  (CLIP); the 0dB LED indicate that the signal level is at 0dBu 

   (0.775Vrms), the LIMIT LED light up indicate the limiter is activated; The red LED aside the 

   MUTE button indicate that the output channel has been muted when light up.

   The LED array of AES / EBU and DANTE lights up indicate that AES-3 digital audio or DANTE  

   network audio is connected and the audio signal is fed into the unit. 

● 9.3.5 Audio Functions

 

● 9.3.5-1 Gain

    Input and Output Gain are separately adjustable from -48dB to +12dB in 0.1dB increments. 

    The output gain menu also provides for selection of input source(s) for a given output channel,  

    as well as polarity of the outgoing signal. Any input or combination of inputs can be routed to  

    any or all outputs. Beware of that two signals which share significant content, such as a stereo 

    source, will be up to 6dB louder when combined.

● 9.3.5-2 EQ

    The DSP-428 EQ section offers full parametric EQ filters on inputs and outputs, each input  

    and output channel has 10 selectable EQ filters, filter type is selectable between Bell, Notch, 

    Low Shelf, High Shelf, All Pass, BandPass, Low Pass and High Pass. 

    Filter's Center/Cutoff/Corner frequency is adjustable from 20Hz to 20 kHz; ±12dB of boost/cut  

    control range and -40dB of attenuation range for the Notch filter. 

    Q factor or BW (Bandwidth) of Bell type filter is adjustable from Q= 0.2 to 25, for Notch filter  

    Q=10 to 80, for Low & high Shelf filter Q=3 to 25, for Low-pass & High-pass filter Q=0.5 to 2, for  

    All-pass & Bandpass filter Q=0.2 to 25.

● 9.3.5-3 Delay

    Within the DSP-428, up to 2000 milliseconds of time delay are available for input channels,   

    allowing secondary loudspeaker clusters to be time aligned with the primary speakers up to 2,252  

    feet (686m) away from the main stage area.

    Output channels have the same time delay as well; output delay is best used to align discrete  

    drivers within a speaker cabinet or cluster, the delay time unit can be selected as Second,   

    Millisecond, Feet, Inch, Mil-inch, Meter and Millimeter.
