DP48X Professional Digital Audio Processor, 4 Inputs, 8 Outputs, Power Shelf, Processor with RIR DEQ, 192 kHz Sampling Rate, Speaker Management System
The DA-48 series utilizes the latest SHARC ADSP21489 fourth-generation ADI processor. It features integrated routing, gain, delay, compression, limiter, mute, equalizer, high-pass/low-pass filters, all-pass filters, and phase, along with many other conventional audio algorithms. In addition, the following customizable functions are included, each of which can be independently enabled or disabled.
Parameters
● 96 kHz / 192 kHz sampling rate switch, 32-bit 400 MHz DSP processor, 24-bit AD/DA conversion.
● Each input channel is equipped with six-stage automatic feedback suppression.
●The input processing section includes 3 DEQs, 12 PEQs, FIR filters, noise reduction, gain, mute, phase and delay processing, and other functions.
●The output processing section includes split FIR and IIR filters, 16-parameter balance, gain, mute, compressors, peak cutter, phase, time delay, and adjustment of processing units such as muscle.
●All PEQ channels offer adjustable gain, bandwidth, continuously variable frequency, and filter type selection: parametric balance, low-frame filtering, enhanced filtering, low-cut filtering, and high-cut filtering. Phase switching sequences are available in 1st and 2nd order.
●All DEQ input channel gain, bandwidth, continuously variable frequency, filter type, dynamic threshold, ratio, start time, and recovery time are continuously adjustable.
● All input and output channels feature independent phase curve adjustment. The PEQ type selection curve setting offers a phase shift of 180 degrees in order 1 and 360 degrees in order 2.
● The IIR crossover filter type can be selected: Butterworth, Ningke, Bessel, with a slope of -6 dB/dB/Oct to -48 (optional).
● Split FIR filter: Optional between sampling points in the 256 to 512 format, with many optional types and a continuously adjustable cutoff frequency of 20 kHz.
● The input channel noise gate threshold, start time, recovery time, and continuous operation time are adjustable, and the noise port percentage is independently adjustable.
●The compressor valve output channel's value, soft point, ratio, start time, and recovery time are continuously adjustable. The output also functions as an independent tip cutting machine, with adjustable threshold, start time, and recovery time.
●All input and output channel delay modules have a delay time of up to 1200 ms.
●The front panel features a 2-inch LCD display, an external Wi-Fi interface, and a USB port. The rear panel has an RS485 interface, allowing connection to third-party central control systems and up to 250 devices.
