(6) EQUALIZER CONTROLS
All channels are fitted with a three-band EQ - High, Mid and Low
controls. The Mid control has a parametric Mid Freq control with
a 350Hz-5KHz range. All three bands have up to 15 dB of cut
and boost, with a center detent for OFF. The frequency response
is flat when all three EQ knobs are in the center detent position.
The High and Low shelving controls have their frequencies fixed
at 12 KHz and 80Hz respectively. The Mid control has a
parametric Frequency Control. This control can be used to
locate the frequency of the midrange tones that you want to
accentuate or cut. The channel EQ is a valuable feature of the
mixer as it allows the user to control the tonal characteristics of
each channel separately. For example, boosting the Low can
fatten the sound, add bass to vocals, or extra punch to bass,
drums and synths. The Mid control, with the Mid Freq set to
higher frequencies, can be used to define percussive instruments
or bring out the edge of vocals; when set to lower frequencies
the Mid can boost low midrange frequencies to fatten up guitars,
toms, or bring warmth to vocals. Adjusting the High control can
provide a crisp sounding high end. Another very important, yet
often overlooked technique is to use the EQ to subtract from the
mix. Cutting the High control can reduce unwanted sibilance,
hiss, cymbals, or high frequency feedback, while attenuating the
Mid or Low can also eliminate feedback or clear up a muddy
sounding mix. The Mid Freq control can also be used to reduce
any feedback from 250Hz to 6Khz. Cutting the High and Low,
then pushing up the
Channel Fader (10) is equivalent to mid
range boost!
The Stereo Channel 7/8 has a fixed Midrange control with
+/-15dB of attenuation at 2.8 KHz.
[Note: Always reset a channel’s input Trim Control (3) (or
external device’s output level) after altering the amount of
equalization.]
The key to successful equalization is to avoid excess. Too much
equalization on the input channels will result in a mix that is
smeared together with nothing specifically defined. During
rehearsals, experiment with the equalizer controls on various
instruments, vocals and combinations of these mixed together to
become familiar with various equalizer settings.
(7) AUX 1 CONTROL (PRE-FADER)
The channel Aux 1 control is mono, post-EQ, and pre-fader - the
signal level sent to the Aux Send 1 bus will be unaffected by the
channel fader setting. This configuration is ideal for almost all
monitoring purposes: for example, for a separate stage monitor
mix in live performances or a studio room monitor in recording
applications, such as a headphone cue system.
(8) AUX 2 / EFFECT CONTROL (POST-FADER)
This control adjusts the level of signal sent to the Aux Send 2 or
the internal DSP Echo Effects.
The channel Aux 2 control is mono, post-EQ, and post-fader
meaning the signal level sent to the Aux 2 bus will be affected by
the channel fader setting. For almost all effects send purposes,
you will want to use the post-fader Aux 2, so that when a fader
level is adjusted, any reverb send from that channel follows the
fader. Otherwise, when the fader is pulled down, the reverb from
that channel would still be audible. You can also use this Aux 2
send to feed inputs of a multi-track recorder or any other
unbalanced line level application. On the other hand, for cueing
purposes and monitor amplifiers, use the pre-fader Aux 1 (i.e.
independent of the channel fader).
The Aux 2 Effect Send controls also adjust the level sent by each
channel to the internal DSP (Digital Sound Processor) Echo
Effects.
(9) PAN / BALANCE CONTROLS
The channel Pan positions the output of the channel in the
left/right stereo field of the Master mix. Its constant-power design
ensures there are no level discrepancies whether a signal is
hard-panned, center-stage, or somewhere in-between. The
Balance Control for Stereo Channel 7/8 increases or decreases
the volume of each Left and Right signal as the control is
adjusted.
(10) CHANNEL FADER
The channel faders determine the output signal level to the Left &
Right Master faders. They offer a smooth logarithmic taper for
optimum control of the signal.
2. MASTER CONTROL, EQ, & HEADPHONE SECTION
(11) AUX RETURN LEVEL CONTROL & PAD SWITCH
This control adjusts the signal levels from the Stereo / Mono Aux
Return Inputs, which are then mixed into the Left and Right
Master bus. These can be used to return effected signals into the
PMX-8700 powered mixer or they can be used as auxiliary inputs
from line level devices such as keyboards or Tape Returns of
multi-track recorders. The internal Echo Effects cannot be applied
to these auxiliary returns. The AUX Return is equipped with a
-20dB pad switch for optimum level control.
(12) HEADPHONE OUTPUT & VOLUME CONTROL
The Headphone (12) stereo output can be used to monitor the
L-R Main outputs or the Aux 1/Aux 2 output levels depending on
the settings of the Headphone LED Display
Select Buttons (14) .
One ear can monitor the Left or Aux 1 while the other ear
monitors the Right or Aux 2. The output will power headphones
with impedances of 8 ohms or greater. The volume control
adjusts the level of the headphone output.
[Warning: Make sure to set the headphone volume to minimum
before putting on headphones as loud levels can damage
hearing and may cause hearing loss.)
(13) PHANTOM POWER LED
The red LED will illuminate when 48V Phantom Power is
enabled. The LED indicates the actual phantom power sent to
the inputs which takes several seconds to discharge completely
when the
Phantom Power Switch (30) is turned off.
[Note: When turning on the Phantom Power switch, turn the
Master Volumes to minimum.]
