User manual for the Marani DPA2448QR 2 x 4 Input / Output Speaker Processor

The user manual for the Marani DPA2448QR 2 x 4 Input / Output Speaker Processor provides necessary instructions for the proper use of the product Pro Audio - Installation Sound - System Processors.

The DPA2448QR 2 x 4 Input / Output Speaker Processor from Marani comes with 2 inputs displayed by rows of 6-level LEDs and 1 clip LED. The activity of 4 outputs is displayed by rows of 5-level LEDs, 1 clip LED, and 1 limiter LED.

This unit has 2 analog inputs, a stereo digital input, and 4 analog outputs. Each input has 5 parametric filters and each output has 7 parametric filters. All the input and output filters can be selected to be Bell, 1st / 2nd Ord shelvings with -3 dB at cutting frequency. Symmetrical shelving with variable Q, HP / LP with variable Q, 1st / 2nd Ord, and all pass (90 / 180° phase rotation at the cutting frequency), with bandpass and notch is also available.

The outputs X-Over section has Butterworth, Linkwitz / Reyleigh, and Bessel filters up to 48 dB/Oct or custom selectable HP / LP up to 48 dB/Oct configurable by the user as cascade of IInd Ord cells adjustable in Freq and Q. Outputs are available on the RMS compressor with a selectable ratio of up to 32:1 and an adjustable soft / hard knee.

The output peak limiter with THR in Vp or dBu offers loudspeaker protection. The RMS compressor and peak limiter's THR can range up to -30 dBu. Each input and output channel has delays up to 850 ms with steps of 22 µs. Linking functions between inputs and outputs are also available. The function allows having ramps close the output level on parameter changes when the unit is used for installation. This function can be excluded when the unit is used live and it is necessary to perform small changes to the set parameter on the fly.

The Pc software for the included remote control allows connecting up to 32 units in net up and shows the phase of the filter setting. It also enables graphical adjustment of the RMS compressor and peak limiter.
