Network: Questions & Answers
Network is ok but there is no sound.
You should be aware that the MMM
cannot support all data formats that are
available on the Internet. It can occur
that a station cannot be played. See
Technical data
Other reasons why your Internet Radio
doesn't play:
• Not all radio stations broadcast 24/7
• Radio stations may not be available
any more
• The Revox equipment is muted
• The provider's (Radio Sender/
Provider) server capacity is fully
utilised
Transmission within your network breaks
down because:
• (Internet) network problems
• Server capacity fully utilised
NETWORK QUESTIONS / TIPS
The connection is lost after a few
minutes:
This is a system-based characteristic of
the UPnP standard. Active
communication starts on a port with a
number higher than 1024 and then
changes regularly during operation. Not
all firewall programs recognise this
knocking on different doors as a
continuous connection. Depending on
the configuration, the firewall may
decide against an unknown client in
case of doubt.
Depending on the firewall software, this
can be resolved through the following
actions:
• By using a fixed IP and without DHCP,
define the MMM as a so-called
Trusted Host, i.e. a device from which
all communication is considered to be
trustworthy.
• Allow the server to accept incoming
and outgoing communication with the
MMM over ports 1024 - 65535.
Activate the exception setting for "UPnP
Framework", e.g. Windows XP Firewall or
activate "Permit UPnP communication".
