1. Introduzione

Congratulazioni per l'acquisto dei diffusori

PERFORMANCE

!

Per un impiego corretto dei diffusori seguite le istruzioni
riportate in questo manuale. Buon divertimento e buon
lavoro.

2. Norme di Installazione e Uso

1. La protezione e la manutenzione.

Evitate di vesporre collocare i diffusori in vicinanza di
forti fonti di calore e di esporli direttamente alla luce
solare, alla pioggia, all’umidità, alla polvere o ad intense
vibrazioni. Lasciate l’apposita griglia di protezione
sempre applicata al diffusore. In caso di avaria non
aprite il diffusore, ma rivolgetevi al più vicino Centro di
Assistenza GENERALMUSIC.

2. Prevenzione di possibili disturbi.

Collegando gli apparati del vostro impianto audio,
ponete molta attenzione ai cosiddetti “loop di massa”
che potrebbero causare ronzii: in caso di disturbi,
provate ad agire sullo switch 

EARTH LIFT/SHIELD

posto sul pannello controlli del diffusore.

3. Collegamenti

Prima di collegare il diffusore alla presa della corrente,
accertatevi che la tensione di rete corrisponda a quella
indicata sul retro dell’apparato (è accettata una
tolleranza fino a ±10%). Collegate il cavo di
alimentazione al diffusore sempre prima di accenderlo
e rimuovete il cavo sempre dopo aver spento il
diffusore.Per evitare pericolosi picchi di segnale
effettuate i collegamenti con altri apparati sempre a
diffusore spento e accendete sempre prima il mixer e
poi il diffusore.

4. I cavi di collegamento (fig. 4)

Per il collegamento di casse amplificate al mixer
accertatevi di utilizzare sempre e solo cavi di segnale
schermati costituiti da due fili più una calza che funge
da schermo. L’utilizzo di cavi non schermati potrebbe
determinare l’insorgere di fastidiosi ronzii e rumori di
fondo. Per il collegamento di casse passive
all’amplificatore di potenza accertatevi di utilizzare
sempre e solo cavi di potenza costituiti solo da due fili
di uguale sezione. L’utilizzo di cavi di segnale potrebbe
determinare un’eccessiva dispersione di potenza.
Verificate periodicamente che i cavi impiegati siano in
buono stato, con le connessioni realizzate nel modo
corretto e con tutti i contatti in perfetta efficienza, in
modo da evitare inconvenienti come falsi contatti,
rumori di massa, scariche, ecc.

3. Pannello connessioni (fig. 2)

1.   Connettori XLR + JACK collegati in parallelo

(LINK) per l’ingresso ed il rilancio del segnale.

1. Introduction

Congratulations for having chosen 

PERFORMANCE

loudspeaker systems!
To make the best use of the PERFORMANCE systems,
please read this manual thoroughly before operating the
equipment.

2. Instructions for use and installation

1. Protection and maintenance.

To avoid jeopardizing correct operation, it is best not
to position the enclosure for long periods in exposed
places (damp, high temperature, etc.), in dusty
environments or those subject to strong vibrations. On
this subject, it’s advisable to always leave the protective
grille mounted on the enclosure. In the event of
breakdown, do not open the enclosure, but contact the
nearest GENERALMUSIC Service Centre.

2. Prevention of possible interference.

Avoid installing your equipment in the vicinity of radios,
televisions, etc., since this could cause noisy
disturbance. When connecting other equipment to your
sound system, pay close attention to so-called earth-
loops, which can cause hum: in the event of
interference, try using the 

EARTH LIFT/SHIELD 

switch

on the enclosure’s control panel.

3. Connections.

Before connecting the enclosure to the mains supply,
make certain that the current corresponds with that
indicated on the rear of the unit (there is an allowance
of ±10%). Always connect the power cable to the
enclosure before switching on the enclosure and always
remove it after having switched off. Remember to
always connect or disconnect other equipment with the
enclosure off and to always switch on the mixer first,
then the enclosure: in this manner, annoying and often
dangerous peaks are avoided.

4. Connector cables (fig. 4).

When connecting amplified enclosures to the mixer,
make certain to always use only screened signal cables
made up of two wires plus a braid/screen: the use of
unscreened cables could in fact probably cause
annoying hum and noise. When connecting passive
enclosures to the power amplifier, make certain to
always use only power cables made up of just two wires
with the same cross-section: the use of signal cables
could cause an excessive loss of power. Check
periodically that your cables are in good condition,
correctly wired and with perfectly efficient contacts: in
fact many problems and drawbacks (false contacts,
ground hum, crackles, etc.) are caused by the use of
unsuitable or damaged cables.

3. Connection panel (fig. 2)

1.   XLR-F + JACK sockets connected in parallel for

the signal input and linking.

2.   XLR-F + JACK sockets connected in parallel for

the signal input and linking (only PFM15SA and
PFM18SA).

3.   XLR-M + JACK sockets connected in parallel for

the connection of the satellites (only PFM15SA
and PFM18SA).

4.   Control for selecting the crossover frequency from

a 80Hz to 320Hz (only PFM15SA and PFM18SA).

5.   SIGN/COMP LED (only PFM15SA and PFM18SA):

show the presence of a signal with minimum level
-26dB (green color) or the built-in compressor
operating (red color).

6.   Control of the signal level sent to the built-in

amplifier.

7.   Control for separating the electrical earth from that

of the chassis.

8.   ON/OFF switch with LED indicator.
9.   Power supply socket.
10. JACK 1/4” power input.
11. 1/4” JACK power output for the linking of two

loudspeaker systems in series (only in the 8-Ohm
versions).

10. 1/4” JACK output power with 230 Hz

CROSSOVER for the connection of the satellite to
the sub-woofer (only PFM15S and PFM18S).

4. PFM15SA and PFM18SA connections (fig. 3)

PFM15SA and PFM18SA have two balanced LEFT &
RIGHT outputs to enable the use of the system in
STEREO or MONO. These outputs feed out the signal
coming from the ACTIVE CROSSOVER.

1. STEREO configuration

Connect the mixer’s RIGHT output to the sub-woofer’s
RIGHT input and the sub-woofer’s RIGHT output to the
RIGHT input of the RIGHT amplified enclosure. Connect
the mixer’s LEFT output to the sub-woofer’s LEFT input
and the sub-woofer’s LEFT output to the LEFT input of
the LEFT amplified enclosure.

2. MONO configuration

Connect the mixer’s RIGHT output to one of the two
inputs (LEFT or RIGHT) of the RIGHT-HAND sub-
woofer and the corresponding sub-woofer output to the
input of the RIGHT-HAND amplified enclosure. Connect
the mixer’s LEFT output to one of the two inputs (LEFT
or RIGHT) of the LEFT-HAND sub-woofer and the
corresponding sub-woofer output to the input of the
LEFT-HAND amplified enclosure.
