ECURITY
VENTURE AUDIO appliances are designed to operate in a perfect reliable and durable
condition. This operation can however be influenced by external events. Some of them will
require the action of the inner
VP100
Reference
security system.
This security system aims at protecting the appliance from any over-voltage, for instance,
as they also act to protect the whole Hi-Fi elements under the preamplifier
« responsibility ». Speakers for instance are this way protected from DC offset (at input or
output of the preamplifier), often issued by source components such as CD players; once
amplified, they can cause irreversible damages.
An activated security (front red LED is ON) will block the preamplifier operation until the
problem or cause is fixed. In case of mains over-voltage for instance, the fuse within the
external power-supply unit may have been blown. Please, only replace the fuse with the
same one, as described here-under. In case of difficulties in finding these fuses, please
don’t hesitate to contact us.
For more information on the reasons of security system calls, please refer to the
associated table within the « questions and answers » chapter.
Last, it is important to underline that these are exceptional cases, which never occur under
normal conditions and good quality Hi-Fi elements (this implies that normal conditions do
not call the security system and consequently do not require fuse changes).
External:
A 500 mA (slow-blow) fuse is used on the mains socket base, within the external power-
supply unit (for 230V)
A 1A (slow-blow) fast fuse is used on the mains socket base, within the external power-
supply unit (for 100-120V)
Internal:
No fuse here, but a relay-based security system.
