Max amplifier power not excess a human ear’s pain threshold
A: 50W usually is even excess power in most cases. Sound pressure level (SPL) in average is >90dB. Physical meaning of SPL – it provides sound pressure 90dB on distance 1m by providing 1W of power. 90dB is already a loud sound. A pain threshold in the human ear is 114dB. So it is enough with 20W of amplifier power to reach this pain threshold by using decent loudspeakers. Of course, we need to take into account also how big is the room where the loudspeakers are installed, but mostly excess amplifier powers are just a marketing gimmick.
Interconnection with KNX/EIB
A: The device has built-in support for KNXnet/IP. You have to interconnect it with a network where KNX IP Router (e.g. Logic Machine 3) is present and make sure that IP Router is not blocking telegrams going from/to the Streaming Player
Why is there no KNX TP1 interface?
A: It is affecting audio quality, while Ethernet is galvanically isolated
No access to KNX bus through IP Router
A: Try to switch off filtering table on IP interface
How to make playlists?
– once you are playing some playlist, tracks from it appears also in Streaming Player’s Audio Control menu
No tracks seen from remote media controller application
A: When doing first Upgrade Database for your Streaming Player, it may take some time while the database is updated. Do not restart Streaming Player during this process, just be patient.
No tracks seen from USB drive
A: Streaming Player supports FAT/FAT32/NTFS/EXT4 file-systems, please format the drive using one of these file-systems
