CARATTERISTICHE DELLA SEZIONE DI AMPLIFICAZIONE E DI CONTROLLO

L’amplicatore DIGIPRO G3 è il cuore dI SIGMA S218.

Il sistema è silenzioso ed il controllo è afdato ad un

DSP dedicato che gestisce diversi parametri.

La potenza di amplicazione sonora è di 1800 W RMS.

Il pannello dell’amplicatore è caratterizzato

da:

ATTENZIONE!

• Sezione di Input, Output e Controllo

• Sezione di Alimentazione

Italiano

• Non tentare in nessun modo di aprire

l’amplicatore.

• In caso di surriscaldamento eccessivo, il

volume audio viene ridotto gradualmente

no alla stabilizzazione termica del

modulo. Il livello viene ristabilito

automaticamente al raggiungimento della

corretta temperatura di funzionamento.

• In caso di malfunzionamento,

interrompere immediatamente

l’alimentazione, scollegando il modulo

dalla rete, e contattare un riparatore

autorizzato.

• Il diffusore viene fornito con un fusibile

già montato per operare nel range 220-

240 V. Se è necessario operare nel range di

tensione 100-120V~:

1. Disconnettere ogni connessione,

compresa l’alimentazione.

2. Attendere 5 minuti.

3. Sostituire il fusibile con quello

fornito nella confezione per il range

100-120 V.

SEZIONE DI ALIMENTAZIONE SEZIONE DI INPUT, OUTPUT E CONTROLLO

• Non rimuovere mai la griglia frontale di

protezione del prodotto. Per prevenire

il pericolo di scossa elettrica, in caso

di danneggiamento accidentale o

sostituzione della griglia di protezione (da

effettuarsi presso il servizio assistenza),

disconnettere immediatamente

l’alimentazione. Non connettere mai

l’alimentazione di rete mentre la griglia è

rimossa.

Per la connessione dell’alimentazione del dispositivo inserire il connettore del cavo powerCON in dotazione

in “AUTO RANGE MAINS INPUT” [8]. Inserire quindi la spina in una presa dotata di conduttore di terra.

Italiano

Se si desidera rilanciare l’alimentazione ad un secondo speaker, è necessario utilizzare

un cavo con connettori powerCON (non fornito). La massima corrente e potenza del

sistema rilanciato (compreso l’assorbimento di S218) è indicata sulla serigraa e riportata

WARNING!

• Input, Output and Control Section

• Power Supply Unit Section

English

• Never attempt to disassemble the amplier

in any way.

• In case of overheating, the audio volume

is gradually reduced until module thermal

stabilization. The level is automatically

restored when the correct operating

temperature is reached.

• In the event of a malfunction, immediately

cut power supply off, by disconnecting the

module from the mains, and contact an

authorised repair centre.

• The fuse installed at the factory is rated for

operation in the 220-240 V voltage range. If

you need to operate the speaker in the 100-

120V~ range:

1. Disconnect all connections,

including the power supply

connection.

2. Wait 5 minutes.

3. Replace the fuse with the fuse

rated for the 100-120 V range,

which is included in the package.

POWER SUPPLY UNIT SECTION INPUT, OUTPUT AND CONTROL SECTION

• Never remove the front grille protecting

the product. To prevent electric shock,

in case of protection grille accidental

damage or replacement (to be carried out

at the after-sales service), immediately

2. FIRST POWER-UP

CONFIGURATION AND OPTIMISATION

SIGMA S218, used in a stand-alone conguration, is characterised by

omnidirectional sound emission. This feature is emphasised in case of

low frequencies, while it decreases as frequency increases.

For subwoofer use optimisation in given congurations, the control

panel displays the following:

• “OUTPUTS” SECTION [4]

1. Xover (the signal present at OUTPUTS may be ltered with a

crossover frequency for daisy chain to a speaker, at 120 Hz or

90 Hz)

2. Outputs Mode (Link if the signal present at OUTPUTS is the one

applied to the subwoofer, Xover if the signal at OUTPUTS is

ltered according to the frequency selected by means of Xover

button)

• “SUBWOOFER SETUP” [5]:

1. Delay (applicable delay: 0 ÷ 4.5 ms, with 0.5 ms steps)

2. Polarity (0°, or 180°, useful for wavefront optimisation through

acoustic wave phase reversal)

Before power-up, set Subwoofer Level selector [3] to 0 dB (Mono or

Stereo, depending on the selected conguration).

INPUT CONNECTIONS AND AUDIO DAISY CHAIN

CASE A (MONO connection) between subwoofer and speaker:

According to the specic conguration (mono or stereo), one or two cables (not supplied) are required at

input and at daisy chain. XLR connectors are required.

In the event of a MONO connection between subwoofer and speaker:

1. Connect mixer output to subwoofer INPUTS 1 connector

2. Connect subwoofer OUTPUTS 1 connector to speaker input.

3. For each speaker, select the type of input impedance on LINE.

4. For each channel in the conguration, set subwoofer OUTPUTS MODE [4] to XOVER, in order to daisy-chain a

signal ltered to the crossover frequency to the speaker.

English

28

SIGMA S218 Cod. 420120258 REV. 1.0

CASE B (STEREO connection between a subwoofer and 2 speakers)

1. Connect mixer L, R outputs to subwoofer INPUTS 1 and 2 respectively.

2. Daisy-chain the signal to the speakers connecting OUTPUTS 1 to LH speaker Input, and OUTPUTS 2 to RH

speaker Input.

3. For each speaker, select the type of input impedance on LINE.

4. Select XOVER [4] frequency and set subwoofer OUTPUTS MODE [4] to XOVER, in order to daisy-chain a

signal ltered to the crossover frequency to the speaker.

CONNECTION AND POWER DAISY CHAIN

For power supply connection of the device, insert the connector of the supplied powerCON cable into

“AUTO RANGE MAINS INPUT” [8]. Then insert the plug into an outlet having a proper earth conductor.

English

If you want to daisy-chain the power supply to a second speaker, use a cable having powerCON connectors

(not supplied). The maximum current and power of the daisy-chained system (including S218 absorption)

are indicated on the screen print as well as in the POWER SUPPLY SPECIFICATIONS section of SPECIFICATIONS.

3. USAGE EXAMPLES

• Types of installation other than those here described are not allowed.

• Never use the handles to suspend the subwoofer

• Always check that the positioning is stable and that the installation does not pose a danger to

people, animals or property.

English

FLOOR USAGE

SIGMA S218 subwoofers may be used directly on the oor (see

gure opposite showing a usage example.)

USAGE WITH SPEAKER IN A STACK

A speaker may be installed directly on SIGMA S218 subwoofer.

In particular, we recommend congurations with: SIGMA S215 or

S115/115F.

Fastening by means of additional belts is required to ensure

stable and safe installation, on the optional BP-M20 base (see

ACCESSORIES).

Except for single oor usage, always use BP-M20 accessory and fastening belts, which have to be

properly anchored to the handles.

31

SIGMA S218 Cod. 420120258 REV. 1.0

To completion of the series, the following accessories are provided as options:

• BP-M20 base, required for S218 oor installation in stacked conguration (see USAGE EXAMPLES)
