ALF-DSP88-U
-10-
The Alfatron DSP Controller is a full-feature application, including parameter adjustments and peripheral
accessory settings of all modules, such as RS232, RS485, and click-and-drag panel configuration etc. The most
interesting part is the user interface, which allows the engineer to customize the user interface so that the
integrator can edit it, or the onsite technicians or end users who have no idea of the relevant techniques can
operate it. Advanced security features make it possible for the end user to only access the controls allowed by
the engineer, or designer.
2.2 Audio Input Section
The Alfatron ALF-DSP88-U supports up to 8 fixed analogue audio inputs, which can be connected via removable
balanced phoenix connectors. The analogue input section supports microphone or line-level signals whose
nominal levels range from 0dBu to +48dBu in 3dBu steps.
+48VDC phantom power can be independently switched on/ off for each input.
Preamp gain and phantom power can be conveniently controlled via the DSP Controller.
The Analogue to Digital (A/D) converter, or ADC, adopts an advanced 24-bit 256X sampling converter.
Analogue to Digital (A/D) Converter Technical Specs:
Sampling rate: 48kHz
THD+N: 105dB
Dynamic range: 120dB
Audio format: 24Bit MSB TDM
