Caution
The outputs are powered outputs, which put out a strong,
amplified signal (not a low-level LINE signal!). For this reason,
only PASSIVE loudspeaker systems can be connected. Other
devices could get damaged.
If loudspeakers with an impedance of 4 Ω are used, the two
•
outputs have a maximum power of 900 W.
If loudspeakers with an impedance of 8 Ω are used, the two
•
outputs have a maximum power of 800 W.
3.5 Graphic Equalizer
The EPA900 is equipped with a 7-band graphic equalizer, which
enables you to adapt the sound to the room conditions and your
own ideas for the sound. The equalizer always processes the
LEFT/MAIN and RIGHT/MAIN bus equally.
Fig. 3.6: Graphic equalizer section
EQ ON
You can activate the equalizer using the EQ ON switch.
FBQ ON
Using the FBQ ON switch, you can activate the feedback
detection circuit. This function only has an effect if the equal-
izer is active. For every frequency that causes feedback, the
corresponding LED on a slide control lights up. Lowering the
displayed frequency minimizes feedback.
3.6 Effects Unit
The EPA900 is equipped with an internal stereo effects proces-
sor, which offers 100 different standard effects, including reverb,
chorus, flanger, and echo, as well as various multieffects. It is
permanently integrated into the mixer as a Send/Return effect;
i.e., an adjustable signal portion can be routed to the effects unit
from every input channel. The selected effect is applied to the
signal portions of the channels, and the signals are then mixed
with the direct signals via the stereo bus.

CLIP/SIG
The CLIP and SIG LEDs provide information on the signal level
on the effects unit.
When continuously lit up, the CLIP LED indicates a signal
•
overdrive. In this case, the effects unit input level should
be reduced through lowering of the Send level using the
EFFECTS controls for the input channels.
The SIG LED signalizes that the effects processor is receiv-
•
ing a signal and is working. If the LED is not lit up, the input
signal is too weak.
PROGRAM (PUSH)
You can turn the PROGRAM control knob to select an effects
preset. Then press the knob to activate the selected effect.
EFFECTS (LEVEL)
The EFFECTS (LEVEL) control is used to adjust the effects
signal volume.
