Hi Rotary Selector Switch; Flat; Lo Rotary Selector Switch; 0Db - Dynacord PM2600 Owner's Manual

FRONT PANEL
EQUALIZER SECTION
The controls and rotary selector switches of the equalizer section marked "LO" and "HI" are used to match the
system to different loudspeaker system configurations as well as for the compensation for acoustic problems of
the location.
a) HI Rotary Selector Switch
This rotary selector switch can be set to three different positions. It is used to acoustically improve the MID-HI
frequency range.

FLAT

Set to this position, the MID range is reproduced with a higher level. This setting is
preferable for lower and medium volumes and for achieving best intelligibility.
- 4dB
Set to this position, the MID range at 4kHz is attenuated by 4dB. Sound reproduc-
tion - especially at higher volumes - sounds less aggressive.
- 2dB
Set to this position, normally represents a good compromise. It is not too "sharp"
and at the same time not too "polite". Compared to the -4dB-setting, the upper
MID range is a little less attenuated.
b) LO Rotary Selector Switch
Using this rotary selector switch lets you match the sound reinforcement system to different acoustic require-
ments of the environment. It also lets you the volume levels of the bass channels.
The rotary selector switch is also utilized to adjust the balance of the LO and MID-HI frequency range, mat-
ching the operator's sound expectations. Therefore, the following notes are only meant as inspiration.

0dB

This is the factory pre-set state when shipped. The voltage gain, in relation to the level
of 0dB at 1kHz, is equal for the LO and MID-HI channels.
0dB....-8dB
These positions are preferably used when each MID-HI cabinet is accompanied by
several sub woofers. The LO-frequency range level is attenuated in relation to the
MID-HI range.
0dB....+12dB
These positions are preferably used when each MID-HI cabinet is accompanied only
by a single sub woofer system. In relation to the level of the MID-HI range, the LO-fre-
quency range level is raised.
