Refer to the Velleman® Service and Quality Warranty on the last pages of this manual.
Keep this device away from dust and extreme heat. Make sure the ventilation openings
are clear at all times. For sufficient air circulation, leave at least 1” (± 2.5 cm) in front
of the openings.
Protect this device from shocks and abuse. Avoid brute force when operating the
device.
• Familiarise yourself with the functions of the device before actually using it. Do not allow
operation by unqualified people. Any damage that may occur will most probably be due to
unprofessional use of the device.
• All modifications of the device are forbidden for safety reasons. Damage caused by user
modifications to the device is not covered by the warranty.
• Only use the device for its intended purpose. All other uses may lead to short circuits, burns,
electroshocks, lamp explosion, crash, etc. Using the device in an unauthorised way will void the
warranty.
• Damage caused by disregard of certain guidelines in this manual is not covered by the warranty
and the dealer will not accept responsibility for any ensuing defects or problems.
• A qualified technician should install and service this device.
• Do not switch the device on immediately after it has been exposed to changes in temperature.

temperature.
• This device is a professional audio amplifier for amplifying audio signals. This product is allowed
to be operated with an alternating current of 230VAC / 50Hz or 115VAC / 60Hz and was designed
for indoor use only.
• Important remark: the operation of an amplification system in public or industrial areas is subject
to specific safety instructions. Contact the proper authorities for more information.
• Choose an installation spot where the device will not be exposed to extreme heat, moisture or
dust. Don’t leave cables lying around. They only endanger your own safety and that of others.
• Only use the device in an ambient temperature of -5°C to +45°C. Keep away from direct
insulation and heaters.
• The relative humidity must not exceed 50%.
• Always disconnect the device from the mains during thunderstorms as overvoltage could destroy
the device.
• Never use solvents or aggressive detergents in order to clean the device. Use a soft and damp
cloth.
• Removing the serial bar code from the device will void the warranty.
• The figures in this manual describe the VPA2100U1. Other models and their features are
comparable with the VPA2100U1.
• Use the original packaging if the device is to be transported.
• Keep this manual for future reference.
5. Legal Provisions
• Operating an amplification system can produce extremely high noise levels that may cause
permanent hearing loss. The legal instructions for using an amplification system vary from
country to country. The user is responsible for respecting the legal provisions applicable in his
country.
• Always monitor the sound pressure level when operating an amplification system in discos,
concerts etc. Never exceed the permissible noise level as specified by the law.
• Hearing damage caused by high noise levels can be regarded as a physical injury and may lead to
criminal prosecution.
• Please note that the organiser is responsible for respecting maximum noise levels.
6. Information on Hearing Loss
• More and more younger people suffer from hearing loss of 25dB or more, mainly caused by
listening to loud music. Every person operating amplification systems should know to what sound
pressure levels he is exposed to. In a discotheque, average levels of 75dB to 105dB are reached.
At a rock concert, the sound pressure levels can rise from 95dB up to 115dB. Individual peaks
can exceed the 130dB pain level. Such levels are typical for e.g. motor chain saws.
