Water and moisture:
Do not expose the mixer to rain or moisture or use it in damp or wet conditions.
Do not place containers of liquids on it which might spill into any openings.
Ventilation:
Do not obstruct the ventilation slots or position the mixer where the air flow required for ventilation is impeded.
If the mixer is to be placed in a rack unit or flight case ensure that it is well ventilated.
Heat and vibration:
Do not place the mixer where it is subject to excessive heat or direct sunlight.
Keep the mixer away from any equipment which produces excessive heat or vibration.
Servicing:
Switch off equipment and unplug the power cord immediately if it is exposed to moisture, spilled liquid, objects fallen into
the openings, if the power cord or plug have become damaged, during lightning storms, or if smoke, odour or abnormal
noise is noticed.
Refer servicing to qualified technical personnel only.
Installation:
Install the mixer in accordance with the instructions printed in this User Guide.
Do not connect the output of power amplifiers directly to the mixer.
Only use audio connectors and plugs for their intended purpose.
Read instructions:
Retain these safety and operating instructions for future reference.
Adhere to all warnings printed here and on the mixer and follow the operating instructions printed in this User Guide.
Do not remove cover:
Never operate the mixer if the cover is not correctly fitted.
Power sources:
Only connect the console to mains power of the type described in this User Guide and marked on the rear panel.
Use a power cord with sealed mains plug appropriate for your local mains supply as provided with the mixer.
If the provided plug does not fit into mains your outlet consult your service agent for assistance.
Power cord routing:
Run the power cord so that it is out of the way and not likely to be walked on, stretched or pinched by items placed upon or
against it.
Grounding:
Never remove or tamper with the ground connection or polarity in the power cord.
4.2 Shaping Sound
EQ
filters audio passing through it and allows you to ‘cut’ (turn down) or ‘boost’ (turn up) selected frequencies.
‘Boosting’ a frequency too much may cause the signal to clip or distort. ‘Cutting’ a frequency will cause a reduction in
signal level.
Overuse of EQ may cause the sound to be unnatural. Understanding the frequency
responses of different instruments and how they might overlap will help you make
good decisions on how to EQ musically.
1.
lo
-
cut
(Hi-pass Filter) removes unwanted low frequency noise such as rumble,
handling noise, thumps and proximity effect and helps maintain clarity in the
signal.
lo
-
cut
affects both
Mic
and
Line/Inst
inputs. The corner frequency
is set at 100Hz.
2.
HF
EQ (High Frequency) affects treble frequencies in the signal. The
corner frequency is at 12kHz for adding “brightness” and “definition” to guitars or
for reducing “hiss” in vocals and “harshness” in cymbals.
3.
LF
EQ (Low Frequency) equaliser affects bass frequencies in the signal.
The corner frequency is 80Hz for adding “roundness” and “sub-bass” to bass
guitar or kick drum, or to remove “boom” from toms.
When you’re happy with the input signal level and tone you can disable the
channel’s
PFL
switch and think about how to mix all these sounds together!
4.3 Balancing the Mix
Once you have set input gain levels and applied EQ to source signals, you can start to mix all of your
channels to the outputs. Consider the importance of each instrument and how they should be heard in the
mix.
1.
Make sure all PFL switches on your mixer are disabled to show
MAIN MIX
metering in
LR Meters
.
2.
Slowly raise the
MAIN MIX fader
to around “
0
”.
3.
Turn up channel
MIX
controls to send their signal to the main mix.
4.
You will see the signal level displayed in the
LR Meters
.
5.
As you mix the signals together you will see the combined level getting higher in the meters.
6.
Avoid clipping and leave headroom for any louder moments in the program material.
Average
peaks around “
0
” on the meters are a good indicator.
Maintain a natural sounding balance and relationship between voices and instruments.
i.e. which instruments should be heard more clearly over others.
If you find that
MIX
controls are turned up very high and signal is still low, or
MIX
control is very low but
signal is too high, readjust channel
Gain
and
EQ
controls to improve gain structure and tone (see
section 6.1)
8.
Use
PAN
and balance to separate sounds and give instruments space in the mix or a realistic
impression of where they might sit in the stereo image.
Ideally, high energy LF sounds such as kick drum should be kept centre to distribute them evenly and
share the load between speakers.
