3. Control Elements and
Connections
The EPA900 mixer is equipped with 4 mono and 2 stereo inputs
and an additional AUX input. The input signals are internally
distributed to a stereo bus. It is also possible to use its channels
separately (mono), such as when used for FOH/PA and stage.
Depending on the requirements, one stereo or two independent
mono sounds can be run. An internal effect can be used as an
AUX effect from each channel. The 7-band graphic equalizer is
used to process the stereo bus or the two mono paths.
3.1 Mono Channels (1-4)
Channels 1-4 are designed as mono channels and are used to
connect microphones or mono line-level sources. The connectors
are balanced to ensure high interference resistance. If possible,
you should use balanced cable connectors to profit from the
advantages of this type of connection.

and unbalanced connectors.
PAD
With the PAD switch, you can weaken loud input signals by
20 dB. Use this function if the CLIP LED is lit up and the level
cannot be reduced any further using the LEVEL control.
PHANTOM
With the PHANTOM switch, you can activate the phantom
power supply for all microphone channels. Use the supply for
condenser microphones.
MIC
You can connect either dynamic
microphones or condenser
microphones to the MIC
connector using XLR plugs.
LINE IN
Via the LINE IN connector,
you can connect instruments
(e.g., keyboards, electric guitars)
or other line-level sources
(e.g., CD player, external
3.2 Stereo Channels (5/6-7/8)
Channels 5/6-7/8 are designed as stereo channels and are used
to connect stereo line-level sources.
3.2.1 Line Inputs
LEFT (L) / RIGHT (R)
Via these connectors, you can connect stereo
line-level sources (e.g., keyboard, CD player,
external mixers, notebook sound card). Either
the cinch jacks or the ¼" jacks can be used, but
not both at the same time.
VOICE CANCELLER (CHANNEL 7/8)
The VOICE CANCELLER function enables
voice to be filtered out of stereo signals. This
function is useful for karaoke applications with
a player (CD/MP3 player, etc.).
3.3 Channel Strips
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.
