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. Protect the device against damage by leaving it switched off until it has reached room 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.

• 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.VPA2200U1 Rev. 01 29/07/2011 ©Velleman nv

An Overview on the Different Noise Levels 10dB – Heartbeat 25dB – Whisper 40dB – Average home 50dB – Light traffic 60dB – Normal conversation 70dB – Vacuum cleaner 80dB – Telephone ringing 90dB – Pneumatic drill 100dB – Power mower 120dB – Boom box in car 130dB – Pain level 140dB – Jet plane 30m overhead

• It is important to know that a 3dB increase will double the sound level. The human hearing only recognises a doubling of the sound level when the noise level is increased by 10dB. Hearing loss does not depend on the sound level but on the noise level and starts way before than the pain level.

• Many a one deceives himself by thinking that noise is something you can get accustomed to. Nothing is further form the truth!

• The reason why some people have got accustomed to a certain noise level and are no longer disturbed, is that they have already suffered hearing loss. The damage makes the hearing insensitive to the frequencies forming the loudest part of the noise. Getting accustomed to noise does not mean anything other than trying to get along with hearing loss in everyday life. Hearing loss cannot be recovered and can only be compensated with hearing aids. Subjectively, hearing loss feels like having dampened ears. This effect weakens with time but loss in hearing sensitivity is permanent.

• In order to relax your hearing sufficiently, the noise level should not exceed 70dB for 10 hours. Higher noise levels during this relaxing period can prevent relaxation and promote permanent hearing damage or hearing loss.

WARNING: Protect your ears if you want to prevent hearing damage!

• original appearance and precise manufacturing

• limiter to prevent speaker damage when the amplifier is overloaded

• high audio frequency performance

• amplifier-on time delay and amplifier-off mute protection protect the speaker from transients

Refer to the illustrations on page 2 of this manual. a. Front panel (fig. 1)

To turn the unit ON or OFF, press this button. Before turning ON the amplifier check all connections and turn down the level control. A momentary muting is normal when turning the amplifier ON or OFF. CAUTION: Always turn on your amplifier last, after all your other connected equipment, and always turn OFF your power amplifier before your other connected equipment.

2. Power LED indicators

These LEDs illuminate when the power is turned ON.

3. Limit LED indicators

These LEDs illuminate if any section of the power amplifier’s input are within 3dB of clipping. Occasional blinking of the LEDs are acceptable, but if they remain on more then intermittently you should turn down the level on the amplifier or reduce the output level of the preceding component to avoid audible distortion.

4. Signal LED indicators

These LEDs illuminate to confirm the presence of an input signal greater than 100mV at that channel of the amplifier.29

• If you want to switch off the system, switch off the amplifier first and then the pre-amplifiers in order to avoid transients on the speaker.

PROBLEM POSSIBLE CAUSE SOLUTION

The power cord is not connected.

Check the power cord and any extension cables. No sound.

The power cord of the respective device is not connected properly or not connected at all.

• The connection socket or the plug is dirty.

Check if the power cord and the plugs are tightly connected with the sockets.

• Clean the socket and/or the plug. Noise.

The input signal is too strong.

Reduce the input signal with the gain control. Fan does not work; LEDs do not light.

The power cord is not connected.

Connect the power cord. PROTECT LED stays lit.

Inputs receive DC voltage.

• Overheating due to clogged fan grille.

• Impedance of speakers too low.

• Short circuit in speaker connection or in speaker.

Switch amplifier off and have the device checked by a service technician.

• Clean the fan grille.

• Connect other speakers.

• Switch amplifier off and have the device by a service technician.

12. Cleaning and maintenance

1. All screws should be tightened and free of corrosion.

2. The housing, visible parts, mounting supports and the installation location (e.g. ceiling,

suspension, trussing) should not be deformed, modified or tampered with e.g. do not drill extra holes in mounting supports, do not change the location of the connections.

3. Moving mechanic parts must not show any signs of wear and tear.

4. The electric power supply cables must not show any damage. Have a qualified technician

maintain the device.

5. Disconnect the device from the mains prior to maintenance activities.
