Problem
The "VALID" LED is not lit up, even
though a microphone is connected
and switched on. (The RCS "Mic
PWR" display is lit up).
The "VALID" LED blinks continu-
ously. (Blinking for a short period
during the synchronization process
is normal).
Functions cannot be controlled via
the user port.
▶
Possible causes
No valid data stream – Cause:
The microphone cable connection
is faulty or too long.
The microphone has not been
synchronized because the se-
lected word clock frequency is not
supported.
The microphone supports only
"mode 1" in accordance with the
AES42 standard, i.e. it cannot be
synchronized.
Control via the user port has not
been activated.
▶
Solution
Check to ensure a continuous
cable connection.
Comply with the recommended
maximum cable length and
required cable quality, as appli-
cable for the selected word clock
frequency. Avoid unnecessary
transition points (connectors). See
Section 7.2, Cables.
Select a word clock frequency that
it is supported by all of the con-
nected microphones.
Use a microphone that can be syn-
chronized (any Neumann Solution-
D series microphones).
In the RCS system menu, "Func-
tion controlled by user port"
must be activated for the relevant
functions.
