4. General Guidelines

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.

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.

VPA2100U1 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!

7. Features

• outstanding tone

• original appearance and precise manufacturing

• protection circuits

• 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

8. Description

Refer to the illustrations on page 2 of this manual.

a. Front panel (fig. 1)

1. Power switch

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.

Velleman® Service and Quality Warranty

Velleman® has over 35 years of experience in the electronics

world and distributes its products in more than 85 countries.

All our products fulfil strict quality requirements and legal

stipulations in the EU. In order to ensure the quality, our products

regularly go through an extra quality check, both by an internal

quality department and by specialized external organisations. If, all

precautionary measures notwithstanding, problems should occur,

please make appeal to our warranty (see guarantee conditions).

General Warranty Conditions Concerning Consumer

Products (for EU):

• All consumer products are subject to a 24-month warranty on

production flaws and defective material as from the original date of

purchase.

• Velleman® can decide to replace an article with an equivalent

article, or to refund the retail value totally or partially when the

complaint is valid and a free repair or replacement of the article is

impossible, or if the expenses are out of proportion.

You will be delivered a replacing article or a refund at the value of

100% of the purchase price in case of a flaw occurred in the first

year after the date of purchase and delivery, or a replacing article

at 50% of the purchase price or a refund at the value of 50% of

the retail value in case of a flaw occurred in the second year after

the date of purchase and delivery.

• Not covered by warranty:

- all direct or indirect damage caused after delivery to the article

(e.g. by oxidation, shocks, falls, dust, dirt, humidity...), and by the

article, as well as its contents (e.g. data loss), compensation for

loss of profits;

- frequently replaced consumable goods, parts or accessories such

as batteries, lamps, rubber parts, drive belts... (unlimited list);

- flaws resulting from fire, water damage, lightning, accident,

natural disaster, etc. …;

- flaws caused deliberately, negligently or resulting from improper

handling, negligent maintenance, abusive use or use contrary to

the manufacturer’s instructions;

- damage caused by a commercial, professional or collective use of

the article (the warranty validity will be reduced to six (6) months

when the article is used professionally);

- damage resulting from an inappropriate packing and shipping of

the article;

- all damage caused by modification, repair or alteration performed

by a third party without written permission by Velleman®.

• Articles to be repaired must be delivered to your Velleman®

dealer, solidly packed (preferably in the original packaging), and

be completed with the original receipt of purchase and a clear flaw

description.

• Hint: In order to save on cost and time, please reread the

manual and check if the flaw is caused by obvious causes prior to

presenting the article for repair. Note that returning a non-

defective article can also involve handling costs.

• Repairs occurring after warranty expiration are subject to

shipping costs.

• The above conditions are without prejudice to all commercial

warranties.

The above enumeration is subject to modification according

to the article (see article’s manual).

Velleman® service- en kwaliteitsgarantie

Velleman® heeft ruim 35 jaar ervaring in de elektronicawereld en

verdeelt in meer dan 85 landen.

Al onze producten beantwoorden aan strikte kwaliteitseisen en aan

de wettelijke bepalingen geldig in de EU. Om de kwaliteit te

waarborgen,

ondergaan onze producten op regelmatige tijdstippen een extra

kwaliteitscontrole, zowel door onze eigen kwaliteitsafdeling als

door externe gespecialiseerde organisaties. Mocht er ondanks deze

voorzorgen toch een probleem optreden, dan kunt u steeds een

beroep doen op onze waarborg (zie waarborgvoorwaarden).

Algemene waarborgvoorwaarden consumentengoederen

(voor Europese Unie):

• Op alle consumentengoederen geldt een garantieperiode van 24

maanden op productie- en materiaalfouten en dit vanaf de

oorspronkelijke aankoopdatum.

• Indien de klacht gegrond is en een gratis reparatie of vervanging

van een artikel onmogelijk is of indien de kosten hiervoor buiten

verhouding zijn, kan Velleman® beslissen het desbetreffende

artikel te vervangen door een gelijkwaardig artikel of de

aankoopsom van het artikel gedeeltelijk of volledig terug te

betalen. In dat geval krijgt u een vervangend product of

terugbetaling ter waarde van 100% van de aankoopsom bij

ontdekking van een gebrek tot één jaar na aankoop en levering, of

een vervangend product tegen 50% van de kostprijs of

terugbetaling van 50 % bij ontdekking na één jaar tot 2 jaar.

• Valt niet onder waarborg:

- alle rechtstreekse of onrechtstreekse schade na de levering

veroorzaakt aan het toestel (bv. door oxidatie, schokken, val, stof,

vuil, vocht...), en door het toestel, alsook zijn inhoud (bv. verlies

van data), vergoeding voor eventuele winstderving.

- verbruiksgoederen, onderdelen of hulpstukken die regelmatig

dienen te worden vervangen, zoals bv. batterijen, lampen,

rubberen onderdelen, aandrijfriemen... (onbeperkte lijst).

- defecten ten gevolge van brand, waterschade, bliksem,

ongevallen, natuurrampen, enz.

- defecten veroorzaakt door opzet, nalatigheid of door een

onoordeelkundige behandeling, slecht onderhoud of abnormaal

gebruik of gebruik van het toestel strijdig met de voorschriften van

de fabrikant.

- schade ten gevolge van een commercieel, professioneel of

collectief gebruik van het apparaat (bij professioneel gebruik wordt

de garantieperiode herleid tot 6 maand).

- schade veroorzaakt door onvoldoende bescherming bij transport

van het apparaat.

- alle schade door wijzigingen, reparaties of modificaties

uitgevoerd door derden zonder toestemming van Velleman®.

• Toestellen dienen ter reparatie aangeboden te worden bij uw

Velleman®-verdeler. Het toestel dient vergezeld te zijn van het

oorspronkelijke aankoopbewijs. Zorg voor een degelijke verpakking

(bij voorkeur de originele verpakking) en voeg een duidelijke

foutomschrijving bij.

• Tip: alvorens het toestel voor reparatie aan te bieden, kijk nog

eens na of er geen voor de hand liggende reden is waarom het

toestel niet naar behoren werkt (zie handleiding). Op deze wijze

kunt u kosten en tijd besparen. Denk eraan dat er ook voor niet-

defecte toestellen een kost voor controle aangerekend kan worden.

• Bij reparaties buiten de waarborgperiode zullen transportkosten

aangerekend worden.

• Elke commerciële garantie laat deze rechten onverminderd.

Bovenstaande opsomming kan eventueel aangepast worden

naargelang de aard van het product (zie handleiding van het

betreffende product).
