Important Security Advices
Please read and keep this manual. You should carefully follow all of the safety and operating
instructions before you use the device. Please also note all warnings and special safety
instructions noted in this manual and on the unit.
Connections: Only use the connections as described. Other connections can lead to health
risks and damage the equipment.
Water and humidity: Do not use this device anywhere near water (for example in a bath room,
a damp cellar, near swimming pools, or similar environments). Otherwise your are dealing
with an extremely high risk of fatal electrical shocks!
Insertion of objects or fluids: Be careful to not insert any object into any of the chassis open-
ings. You can otherwise easily come into contact with dangerous voltage or cause a damaging
short circuit. Never allow any fluids to be spilled or sprayed on the device. Such actions can
lead to dangerous electrical shocks or fire!
Opening the unit: Simply put: DON‘T, if you are not a certified SPL technician or engineer.
Really: Do not open the device housing, as there is great risk you will damage the device, or –
even after being disconnected – you may receive a dangerous electrical shock!
Electrical power: Operate the device only from power sources that can provide proper power
in the range from 90 to 264 volts. When in doubt about a source, contact your dealer or a
professional electrician. To be certain you have isolated the device, disconnect all power and
signal connections. Make sure that the power supply plug is always accessible. When not
using the device for a longer period, make sure to unplug it from your wall power socket.
Cord protection: Make sure that your power and audio signal cords are arranged to avoid
being stepped on or any kind of crimping and damage related to such event. Do not allow any
equipment or furniture to crimp the cords. Extra caution is required for the MADI optical fibre
cables, the glass fibre inside the cords can be easily broken by bending or kinking.
Power connection overloads: Avoid any kind of overload in connections to wall sockets,
extension or splitter power cords, or signal inputs. Always keep manufacturer warnings and
instructions in mind. Overloads create fire hazards and risk of dangerous shocks!
Lightning: Before thunderstorms or other severe weather, disconnect the device from wall
power; do not do this during a storm in order to avoid life threatening lightning strikes.
Similarly, before any severe weather, disconnect all the power connections of other devices
and antenna and phone/network cables which may be interconnected so that no lightning
damage or overload results from such secondary connections.
Air ventilation: Chassis openings offer ventilation and serve to protect the device from over-
heating. Never cover or otherwise close off these openings. Never place the device on a soft
surface (carpet, sofa, etc.). Make sure to provide for a mounting space of 4-5 cm/2 inches to
the sides and top of the unit when mounting the unit in racks or on cabinets.
Controls and switches: Operate the controls and switches only as described in the manual.
Incorrect adjustments outside safe parameters can lead to damage and unnecessary repair
costs. Never use the switches or level controls to effect excessive or extreme changes.
Repairs: Unplug the unit from all power and signal connections and immediately contact a
qualified technician when you think repairs are needed – or when moisture or foreign objects
may accidentally have reached inside the housing, or in cases when the device may have fallen
and shows any sign of having been damaged. This also applies to any situation in which the
unit has not been subjected to any of these unusual circumstances but still is not functioning
normally or its performance is substantially altered. In cases of damage to the power supply
and cord, first consider turning off the main circuit breaker before unplugging the power cord.
Replacement/substitute parts: Be sure that any service technician uses original replacement
parts or those with identical specifications as the originals. Incorrectly substituted parts can
lead to fire, electrical shock or other dangers, including further equipment damage.
Safety inspection: Be sure always to ask a service technician to conduct a thorough safety
check and ensure that the state of the repaired device is in all respects up to factory standards.
Cleaning: Do not use any solvents, as these can damage the chassis finish. Use a clean, dry
cloth (if necessary, with an acid-free cleaning oil). Disconnect the device from your power
source before cleaning.
