12. FM Antenna. This socket has to be used to connect your 75 ohms FM antenna. You can use the shipped
indoor “wire” antenna, but to improve the reception, we advise to install an outdoor FM antenna or to
connect the PR4000 to a cable radio network. Normally, when you use a cable radio network you must use
a ground isolator transformer adaptor (GIT). Since your PR4000 is already equipped with a build-in GIT, it is
not necessary anymore to use or to buy such an external transformer.
13. Output Volume control FM1, FM2, FM3 and FM4.
With these attenuators you can level the output vol-
ume of each tuner on the PR4000, so that they can match the levels of other sound sources in your music
system. Each signal can be levelled between -20dB and +10dB.
14. RCA Outputs FM1, FM2, FM3 and FM4.
Use these stereo sockets to connect your tuners to your music
system (e.g. tuner in, cd in, aux in…) Never connect this output to an amplifier loudspeaker output!
When you connect your PR4000 to a microphone input, this input will have signal overload, so the sound
will be masked. In this case you should use a DI-box or other signal levelling device.
15. IR-Receiver Input. By installing an extra IR-eye receiver, your comfort will be increased by 100%. Some
features can then be controlled from the palm of your hand. Always use screened cable to
install this IR-eye.
16. Earth Lift Switching. If “Humm” or “Buzz” occurs when connecting different outputs, this is often caused
by ground or earth loops. In this case you have to set this switch onto the “LIFT” position.
17. Mains Socket. Your PR4000 can be connected to the mains by the shipped standard IEC type power
cord. The socket contains also a 315mAT slow blow fuse. In order to replace the fuse, you need to flip out
the fuse compartment by using a flat screwdriver. Use always the same type. When this fuse blows
frequently, you should bring your PR4000 to a qualified service centre. First check whether you didn’t use a
quick-blow fuse!
