Installing and Looking After the Product
Connection to the electrical mains
Before connecting the device to the mains, make sure that the mains voltage is the same as that
marked on the rear panel (max. tolerance ±10%) and that the POWER supply switch is in the
off
position.
When connecting to the mains it is always important to take the necessary precautions to avoid the risk
of electric shock; for example, do not make the connection with wet or damp hands.
Connections and the prevention of interference
Connections must only be made with the device switched off.
When switching your audio devices on and off, it is best to switch on this device last and switch it off first.
Use quality cables and check their condition regularly. When disconnecting cables from sockets, always
take hold of the connector and not the cable itself; when winding cables, do not knot or twist them.
Do not install too close to radio devices, cell-phones, etc., which normally generate interference.
The device generates magnetic fields: do not place it too close to TVs or video monitors, computers,
audio and video tapes and magnetic media, etc.
Check that the installation site is not subject to industrial interference, strong RFI or power blackouts.
When installing permanent systems:
X
For microphones use balanced cables, especially for long-distance connections.
X
Do not lay audio cables close and/or parallel to electrical lines, telephone lines, IT networks and
70V or 100V speaker lines, or other low-voltage conductors.
X
Flame retardant materials should be used, especially in large installations, even when not strictly
necessary under safety regulations.
Looking After the Product
Do not apply excessive force to the controls (knobs, switches, etc.).
Avoid prolonged exposure to direct sunlight, intense heat sources, strong vibrations and especially damp
or dusty environments or rain, since they may cause malfunctions, deterioration and even electric shocks.
Never insert foreign bodies inside the device or pour liquids of any kind into it.
If the device is to be unused for some time, protect it from dust. Any dust which does collect on the
device can be removed “dry” using a soft cloth or a brush. Never use methylated spirits, acetone or
solvents of any kind.
In case of malfunction
In case of malfunction, contact only an authorised service centre.
