Dynacord PowerMate 2200 Mode D'emploi page 39

One more tip, in case you desperately need another input and all channels of the PowerMate
are already in use:
The microphone input and the phone plug-type inputs are electrically totally separated
from each other. Each input is equipped with its own gain control – respectively trim
control, providing you with the possibility to connect a LINE level sound source in addi-
tion to a microphone. Of course, the two sources share all other controls. Consequently,
separate adjustments are not possible. Hence to that fact, this option is only meant as a
subsidiary function and should only be used when there is absolutely no other alternative.
18. EQ SECTION
The mixer's EQ section allows very differentiated shaping of the incoming audio signal within
miscellaneous frequency bands. Turning one of the EQ level controls to the right enhances/am-
plifi es the corresponding frequency range while turning them to the left lowers/attenuates the
signal of the specifi c frequency band. Before you begin to alter the sound, all EQ controls should
be set to their neutral position; that is: their marker points straight up (locked in place). Do not set
the EQ controls to extreme positions. Usually, minor changes are totally suffi cient and produce
the best results in the overall sound. You should use the natural reproduction as an orientation
mark and rely on your musically trained ear, being the perfect instrument to judge the sound
quality. The moderate use of the MID control is the best remedy to avoid acoustical feedback.
Especially in this frequency range you should try to avoid excessive enhancement. Lowering
the level more or less in this band will provide you with high amplifi cation rates without feedback.

The HI and LO controls of the STEREO channels' EQ section provide a degree of control
that is equally adequate for LINE level inputs and microphones. The MID control is active in a
comparably wide frequency band around 2.4 kHz. With most microphones this is the critical
range, where a slight attenuation offers excellent results.
19. AUX/FX
These controls determine the amount of the summed L/R signal that is send to the AUX/FX
bus. The signal split is POST FADER. For more details on the functioning of these controls,
please refer to the INPUT/MONO section of this owner's manual.
20. AUX3
These controls determine the amount of the summed L/R signal that is send to the AUX3
bus. Depending on the setting of the AUX3 POST switch within the PowerMate's master sec-
tion you can choose if the signal gets split PRE or POST FADER.
