General Precautions
Damage To prevent damage to the controls and cosmetics avoid
placing heavy objects on the control surface, scratching the surface with
sharp objects, or rough handling and vibration.
Environment Protect from excessive dirt, dust, heat and vibration
when operating and storing. Avoid tobacco ash, smoke, drinks spillage,
and exposure to rain and moisture. If the console becomes wet, switch off
and remove mains power immediately. Allow to dry out thoroughly before
using again.
Cleaning Avoid the use of chemicals, abrasives or solvents. The
control panel is best cleaned with a soft brush and dry lint-free cloth. The
faders, switches and potentiometers are lubricated for life. The use of
electrical lubricants on these parts is not recommended. The fader and
potentiometer knobs may be removed for cleaning with a warm soapy
solution. Rinse and allow to dry fully before refitting them.
Lifting To avoid injury to yourself or damage to the equipment take
care when lifting, moving or carrying the console.
Transporting The console may be transported as a free-standing unit
or mounted in a purpose built flight case. We recommend that the console
is surrounded by shock absorbent foam to protect it from damage during
transit. Always use adequate packing if you need to ship the unit. Protect
the controls to avoid damage when moving the console.
Hearing To avoid damage to your hearing do not operate any sound
system at excessively high volume. This also applies to any close-to-ear
monitoring such as headphones and IEM transducers. Continued
exposure to high volume sound can cause frequency selective or wide
range hearing loss.
Important Mains plug wiring instructions.
The console is supplied with a moulded mains plug fitted to the AC
mains power lead. Follow the instructions below if the mains plug has
to be replaced. The wires in the mains lead are coloured in
accordance with the following code:
WIRE COLOUR TERMINAL
European USA/Canada
L LIVE BROWN BLACK
N NEUTRAL BLUE WHITE
E EARTH GND GREEN & YELLOW GREEN
The wire which is coloured Green and Yellow must be connected to
the terminal in the plug which is marked with the letter E or with the
Earth symbol. This appliance must be earthed.
The wire which is coloured Blue must be connected to the terminal in
the plug which is marked with the letter N.
The wire which is coloured Brown must be connected to the terminal
in the plug which is marked with the letter L.
Ensure that these colour codes are followed carefully in the event of
the plug being changed.
