DIGITAL SPEAKER MANAGEMENT SYSTEM
32-bit digital 2 / 4 in, 4 / 8 out speaker management system, including RS485 interface.
The Marco Audio digital speaker management systems are equipped top-end “Texas Instruments” DSP processor AD/DA converters with sampling rate up to 192KH enable a dynamic range of up to 114dB.
The DSM24 and 48 is equipped with 2 / 4 analog and digital (AES/EBU© format) inputs. 4 / 8 output and with RS485 connector. The use of modern and fast DSPs enables a latency (analog to analog) of 0.63ms only.
Each input channel includes 6 equalizers (with low-shelf, high-shelf and parametric function), a delay function and a noise gate.
The polarity of each input channel can be switched from + to –.
Each output channel includes 6 equalizers (with low-shelf and parametric function) and a delay function. The HPF (high-pass filter) and LPF (low-pass filter) is part of each output channel.
Both offer three different operation modes: Linkwitz-Riley. Butterworth and Bessel (up to 48dB/Oct).
Each output channel includes a high performance limiter.
The integrated flash memory chip offers space for 30 presets, which can be loaded via the preset-menu, three default-buttons or the PC remote software.
