4.3 Analogue Audio Output
The Analogue Output are designed around the
AK4324 24-bit Digital-to-Analogue converter (DAC)
from AKM®. This converter of the S/D type,
ensures an amazing dynamic range of 115 dB. The
analogue outputs are electrically balanced and are
able to output a +18 dBm signal level.
4.4 Digital Audio Output
The Digital AES-3 Output is a true transformer-
balanced output specified by AES. The actual AES
encoding is done by the Cirrus Logic® AES-3
transceiver chip, the CS8420.
The AES-3 outputs will always be synchronous to
the used master clock, which either can be driven
from the external sync input or from the internal
48 kHz clock oscillator.
Combined with the SRC on the AES-3 input this
arrangement enables the MSD’s to be used as a
high performance SRC taking an AES-3 input sig-
nal of any arbitrary sample rate between 32 kHz to
96 kHz and convert it to the internal used sample
rate.
4.5 External Sync Source Input
All supported MSD models are able to use any of
the available AES-3 inputs as an External AES-3
Sync Input. This is a huge advance since no dedi-
cated Sync inputs are required.
The MSD can be set to synchronise to an AES-3
signal in the range 32 kHz to 50 kHz.
4.6 DSP Microcomputer
The MSD data processing is entirely based on a
very powerful Digital Signal Processing (DSP) chip,
a so called DSP (Digital Signal Processor) Micro
computer. By using DSP all errors with ballistic and
scaling found on older analogue VU-Meter based
equipment is virtually eliminated.
The Software Version referred to in the Info Menu is
the software running on this DSP Microcomputer.
The used DSP is a 52 MIPS version of the
Analogue Devices® ADSP-2183, a single-chip
microcomputer, optimised for digital signal
processing (DSP), and other high-speed numeric
processing applications. The computer has
