7 EUROPORT EPA900 User Manual
Channel strips 3.3
Each channel strip is equipped with an equalizer section, an effects control,
and one control each for signal routing and volume control.
TREBLE/BASS
The equalizer section comprises these two controls. With the
TREBLE control, you can modify the high frequencies, and with
the BASS control the low frequencies. Rotate the control knob:
clockwise to boost the frequency range by max. 15 dB. •
counterclockwise to cut the frequency range by •
max. 15 dB.
If you use the equalizer section to boost frequencies, ◊
the signal level of the channel increases. If the CLIP
LED lights up, you need to reduce the level using the
corresponding LEVEL control.
EFFECTS
With the EFFECTS control, you can specify the portion of the
channel signal to be routed to the effects unit. The further
clockwise you turn the control knob, the greater the effect that
is applied to the signal. Turning the knob counterclockwise as
far as possible results in a signal with no effects.
BAL
Use the BAL control of the mono channels to adjust the
position of the signal within the stereo image (left/right) or for both mono paths.
Turn the control:
completely to the left to hear the signal only on the left side, that is the •
LEFT/MAIN path.
completely to the right to hear the signal only on the right side, that is the •
RIGHT/MAIN path.
Positions between these settings will result in a proportionate signal allocation
between LEFT/MAIN and RIGHT/MAIN.
The BAL control determines the levels of a stereo source’s left and right input
signals in relation to each other. Turn the control:
completely to the left to hear only the left signal component of the stereo •
source on the LEFT/MAIN path.
completely to the right to hear only the right signal component of the stereo •
source on the RIGHT/MAIN path.
Positions between these settings will result in a proportionate signal allocation
of the left/right signal component between LEFT/MAIN and RIGHT/MAIN.
CLIP
When lit up, the CLIP LED indicates that the corresponding channel is being
overdriven. If this LED lights up regularly, you need to reduce the level of the
respective channel using the LEVEL control and/or the PAD switch.
LEVEL
The LEVEL control is used to set the volume of the channel signal. If the CLIP LED
is lit up, the level has to be reduced using this control.

Additional connections 3.4
The EPA900 is equipped with additional inputs and outputs as well as a
footswitch connector.
STEREO AUX IN
The STEREO AUX IN sockets are designed as separate ¼" jacks and as a stereo
minijack. You can connect additional devices with adjustable line levels
(e.g., other mixers, MD player) here. The signal is sent directly to the output
busses, with no further adjustment possible. Use either the minijack or the
two ¼" jacks, not both types at the same time. For mono sources, use the
LEFT connector.
EFFECTS FOOTSW
The EFFECTS FOOTSW socket is used to connect a footswitch. You can switch the
effect on and off with the foot switch.
SUB OUT
You can connect an active subwoofer to the SUB OUT socket.
TAPE OUT
You can connect a 2-track recorder (DAT, MD, etc.) to the TAPE OUT sockets.
The two TAPE OUTs carry the output bus signals.
Speaker outputs 3.5
The SPEAKER OUTPUTS connectors on the back of the unit are used to connect the
supplied loudspeakers.
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.
