Venture Products VP100L manual Security, Cleaning

USER’S INSTRUCTIONS

4.SECURITY

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 VP100L security system.

This security system aims at protect the appliance from any over-voltage, for instance, as they also act to protect the whole appliances 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 below. In case of difficulties to find these fuses, please contact us.

For more information on the reasons of security system calls, please refer to the associated table within the « questions and answers » chapter.

At 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:

A500 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.

5.CLEANING

VP100L preamplifier was designed to operate perfectly with no specific setting or maintenance for a large number of years.

In case of dust removal, plainly process using a clean dry rag. In case of a dirty mark, DO NOT use any detergent or solvent, but use a clean wet rag.

Caution:

NEVER clean any appliance while in operation.
