6 Equalizer controls
This set of four controls allows you to individually
modify the channel’s response. Each channel of the
EMX3500 is equipped with a three-band equalizer (EQ)
that has shelving HIGH and LOW controls, and a
peaking MID control with a sweepable center fre-
quency (which is adjusted by the MID FREQ control).
Refer to “Using the Channel Equalizers” on page 12 for
details on the use of these controls.

7 MONITOR control
This control determines the level of the post-EQ/pre-
fader signal that is sent from the channel to the monitor
mixing bus. All signals sent to the Monitor bus are
mixed, then fed to the two MONITOR OUT jacks on the
top panel after their final output levels have been set by
the MONITOR A and B controls in the master control
section.
8 EFFECT 1 control
This control determines the level of the post-EQ/post-
fader signal that is sent from the channel to the Effect 1
mixing bus. The channel signals mixed by this bus
have their overall level set by the EFFECT SEND 1
fader, then are sent to the EFFECT SEND 1 jack. The
output from this jack can be processed by an external
effect device.
9 EFFECT 2 control
This control determines the level of the post-EQ/post-
fader signal that is sent from the channel to the Effect 2
mixing bus. The channel signals mixed by this bus are
sent via the EFFECT SEND 2 fader to the EFFECT
SEND 2 jack on the top panel . The output signal is
also fed into the EMX3500’s internal digital signal
processor. Thus, a signal fed to the Effect 2 bus using
this control can be processed externally or internally.
0 PAN control
This control pans the channel signal across the master
L and R buses, thus determining the perceived position
of the sound from that channel in the output stereo
sound field. If a PAN control is set all the way to the
left, for example, the sound from that channel will be
heard from the left speaker system only. If it is set all
the way to the right, the sound will be heard from the
right speaker system only. Intermediate settings will
cause the sound to appear at corresponding locations
in the stereo sound field.
A Channel ON switch
This switch enables input from the channel to the
mixing buses. When turned off (that is, when the button
is out), the channel will be removed from the mix.
Turning off unneeded channels may help to minimize
noise during quite passages.
B Channel fader
This is the channel’s main level control. It determines
the level of the signal that is sent from the channel to
the master mixing and effect buses. It is the settings of
the input channel faders that determine the “mix,” or
the balance of sound levels between the instruments or
other sources connected to the inputs. When a channel
is not being used, its fader should be set at the mini-
mum position to prevent the addition of unwanted noise
to the main program signal.
