ALF-DSP 88-U
-10-
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 rate converter.
Analogue to Digital (A/D) Converter Technical Specs:
Sampling rate: 48kHz
THD+N: 105dB
Dynamic range: 120dB
Audio format: 24Bit MSB TDM
2.3 Audio Output Section
The Analogue output section
refers to the digital to
analogue (D/A) converter, or DAC,
also adopts an advanced 24-bit 256X sampling converter. Just like the A/D converter, it also uses multi-bit
architecture for broader dynamic range. Unit gain (0dB) is set via volume control, and the analogue output
section is
corrected as +4dBu with 20dB headroom. That is to say that 0dBFS digital signal is equivalent to +24dBu output
signal. If other signal levels are required, you may change the output volume to achieve it.
Digital to Analogue (D/A) Technical Specs:
Sampling rate: 48kHz
THD+N: -100dB
Dynamic range (A-weighted): 118dB
Audio format: 24Bit MSB TDM
On the software output interface there are two controls: Phase and Mute.
Phase: The phase button inverts the phase of the output signal by swopping the polarity.
Mute: Mutes the analogue output of the respective channel
