USB
The L/R master audio signal is always present at the USB interface. This allows using your
PC/Mac for recording while the PM 502 functions as premium A/D converter, without the need
for an external sound card.
Headphone
Stereo phone jack (3.5 mm) for the connection of headphones with an impedance of 32–
600 Ω. The phones output presents the master signal. The corresponding control is described
in section Headphone volume, page 31. The output is protected against short circuit.
Headphones or in ear monitor systems with an impedance below 32 Ω can be connected, in
this case the maximum reachable volume is reduced.
Other connections
USB data storage

integrated audio player of the PM 502. The external memory is scanned automatically for
suitable audio tracks (MP3 or WAV). If audio tracks are detected, the audio player dialog will
be shown in the LC-Display automatically.
Notice!
Powering external drives through USB
