INSTALLATION

CONNECTIONS

1. Strip o the vinyl covering and twist the tip of the wire core.

2. Loosen the knob and insert the wire core into the terminal hole.

3. Tighten the knob to x the wire core in place.

In sta l l th e u nit in a we l l ve nti l at ed p la ce an d n o t exposed to high temperatures or humidity, nor any heat sources such as heaters or radiators. Be sure to leave space around the unit for ventilation to improve heat radiation (at least 30 cm at top, 10 cm at rear, and 20 cm at each side). If not enough space is provided between the unit and walls or other equipment, heat will build up inside, interfering with performance or causing malfunctions.

Before making or changing the connections, switch o the power switch to prevent damaging the product. To connect the speakers, always check the correct polarity (red +) (black -) to avoid damaging them irreparably.

Inputs

Output

The amplifier has four inputs for various audio components, inputs CD and AUX are RCA and have the same function, the XLR input is a balanced, the input BYPASS only allows to use the amplifier only as a power amplifier, not the preamplifier stage.

Incorrect operations are often mistaken for trouble and malfunctions. If you think that there is something wrong with this component, check the points below. Sometimes the trouble may lie in another component. Investigate the other components and electrical appliances being used. If the trouble cannot be rectified even after exercising the checks listed below, ask your nearest ONIX authorized service center or your dealer to carry out repair work.

MANUALE D’USO

INSTALLAZIONE

COLLEGAMENTI

1. Mettere a nudo le estremità dei cavi ed attorcigliarne l’anima di rame.

2. Allentare la manopola ed inserire nel foro del terminale la parte di cavo messa a nudo.

3. Riavvitare la manopola per ssare bene il cavo.

Installare l’apparecchio in un luogo ben ventilato e non esposto ad alte temperature o umidità, ne a fonti di calore quali stufe o radiatori. Assicuratevi di lasciare uno spazio intorno al prodotto per ottenere una corretta ventilazione (lasciate uno spazio minimo di 30 cm in alto, di 10 cm dietro l’unità e di 20 cm ai lati). Se non si rispettano queste distanze l’apparecchio si surriscalderà alterandoil suo normale funzionamento con un possibile guasto.

Prima di eettuare o modicare qualsiasi collegamento spegnere sempre prima l’apparecchio evitando danneggiamenti del prodotto. Per il collegamento ai diusori vericare sempre la giusta polarità (rosso +) (nero -) per non danneggiarlo irrimediabilmente.

COLLEGAMENTO DEI CAVI DEGLI ALTOPARLANTI

Attorcigliate l’anima del cavo.

COLLEGAMENTO DEI CAVI PIN-RCA

1 Canale sinistro

2 Canale destro

4 Spinotto rosso

3 Spinotto bianco

Collegare la spina bianca 3 al canale L (sinistro) 1, e la spina rossa 4 al canale R (destro) 2. Le Spine devono essere inserite saldamente e ben a fondo.

L’amplicatore è dotato di ltri per la soppressione delle interferenze in radiofrequenza, secondo la normativa CEE

MANUTENZIONE DELLE SUPERFICI ESTERNE

Togliere la polvere e lo sporco con un panno pulito e asciutto. Non usare mai solventi, benzina, insetticidi spray ed altre sostanze chimiche su o vicino all’apparecchio perché ne corrodono le superci.

Prendete sempre il lo di alimentazione per la spina. Non tiratelo mai agendo per il lo stesso e non toccate mai il lo con le mani bagnati, perchè questo potrebbe causare cortocircuiti o scosse elettriche.
