DM48 Audio Processor
Overview
Features
2-bit DSP chip processing, 48kHz sampling rate, 24 bit AD / DA conversion
The input processing section includes high-pass, low-pass, 5-parameter equalization, noise gate, gain, mute, phase, delay, and linked adjustment functions.
The output processing section includes frequency division, 7-parameter equalization, gain, mute, compressor/limiter, phase, delay, and synchronization adjustment units.
The PEQ gain, bandwidth and frequency of all channels are continuously adjustable, and the types are selected: parameter equalization, low-pass filter, high-pass filter, low-cut filter, high-cut filter, phase shift 1st order, phase shift 2nd order.
All inputs and outputs can be freely allocated in matrix mode, and each input/output channel name can be changed.
All input/output channels feature independent phase curve adjustment capabilities. When selecting PEQ type, Phase Shift 1 enables 180-degree adjustment, while Phase Shift 2 provides 360-degree adjustment.
All high-pass and low-pass filters, as well as frequency dividers, can be selected from the following types: Butterworth, Linqueryli, and Bessel. The slope can be chosen from-6dB/Oct to-48dB/Oct.
The threshold, ratio, start-up time and recovery time of the output channel's compressor/amplifier are continuously adjustable.
The threshold, ratio, start-up time and recovery time of the output channel's compressor/amplifier are continuously adjustable.
Parameters between any channels can be freely copied, and any channel can be adjusted in sync.
View the PEQ curve adjustment diagram for all input/output channels at any channel.
The built-in test signal generator provides customizable output modes including pink noise, white noise, and adjustable 20Hz-20kHz sine waves, with adjustable signal amplitude.
The front panel features input/output level indicators and a USB control port, while the rear panel includes an RS232 control port. The one-touch connection simplifies and accelerates user operations.
30 user presets, with both device parameters and each preset being stored and called individually. Password protection is also available to enhance device security.
