CHAPTER 4: Operation
Sample Rates
The scaling factor and the base sample rate are indicated by four LEDs.
2 FS LED - indicates scaling factor of sample rate
( ON, yellow) = scaling factor set to 2 FS
( OFF, yellow)= scaling factor set to 1 FS or 4 FS
4 FS LED - indicates scaling factor of sample rate
( ON, white) = scaling factor set to 4 FS
( OFF, white) = scaling factor set to 1 FS or 2 FS
48k LED - indicates the use of 48 kHz as
base sample rate
(ON, green) = base rate of 48 kHz
(or multiple of) is used
(OFF, green) = base rate is different from 48 kHz
44.1k LED - indicates the use of 44.1 kHz as
base sample rate
(ON, green) = base rate of 44.1 kHz
(or multiple of) is used
(OFF, green) = base rate is different from 44.1 kHz
NOTE
With the clock set to internal (INT) the sample rate can be adjusted in the menu.
All other clock sources (word clock, MADI, NET) defi ne the base rate automatically
and the measured frequency of the clock source is indicated then.
The scaling factor of the sample rate has to be defi ned manually when the clock
source is set to internal , word clock or MADI with S/MUX.
High Speed mode - Legacy mode
High Speed mode implements the AES 10-2020 standard, which means that the
MADI frame type is always the same as the sampling frequency of a signal (48 kHz
-> 48 kFrame, 96 kHz -> 96 kFrame, 192 kHz -> 192 kFrame).
In Legacy mode, which most MADI devices on the market are still exclusively
using, for example a 96 kHz signal could be transmitted using 48 kFrame type
(S/MUX). '96k Frame' defi nes a '2 FS' signal (e.g. 96 kHz).
