Caution!
Please, make sure to set the input channel VOLUME controls or at least the MASTER or AUX
VOLUME controls to their minimum position before connecting an external sound source to
any input of the PM 502. This will save you, your audience, and the equipment from
unnecessary discomfort.
Mono inputs (MIC/LINE)
Electronically balanced MIC/LINE inputs 1 to 5 for the connection of a monaural line level
signal source or a microphone. Generally, any type of XLR-type microphone can be connected
as long as its pin assignment is in accordance to the diagram shown in section Pin
assignments, page 43.
The connection of balanced or unbalanced signal sources can also be established through
monaural or stereo jacks, assigned according to the the illustrations in section Pin
assignments, page 43. If the device that you want to connect has a balanced output stage,
the use of balanced cables with stereo jacks is preferable. This type of connection is less
sensitive to the introduction of external noise or HF interference.
Notice!
Please, do not connect E-guitars or E-basses with passive, high impedance outputs directly to
a MIC/LINE input. The MIC/LINE inputs of the PM 502, as with the line level inputs of mixers
from other manufacturers, are designed for the connection of the relatively low source
impedance of electronic instruments. The reproduction of the instrument’s original sound
characteristics will be unsatisfactory. Connect those instruments using a special transformer
or pre-amplifier with very high input impedance. Musical instruments with an active electronic
output (battery-powered) can be connected without any problems.
