SELETTORE PRIORITY

Selettore per attivare la funzione “priority”
su MIC1. Quando il selettore è su ON, i livel-
li di MIC2, MIC3/AUX, LINE vengono abbas-
sati automaticamente (attenuazione -40dB)
in presenza di segnale sull’ingresso MIC1.

SELETTORE PHANTOM

Il pulsante schiacciato attiva l’alimenta-
zione phantom (+21VDC) sull’ingresso
MIC1.

INGRESSO MIC2

Connettore jack mono di ingresso microfo-
nico sbilanciato.

INGRESSO MIC3/AUX

Connettore jack mono di ingresso microfo-
nico o di ingresso linea sbilanciato, sele-
zionabile.

SELETTORE MIC/AUX

Seleziona se l’ingresso in MIC3/AUX sia
microfonico (MIC) o di linea (AUX).

INGRESSO LINE IN

Connettori pin-rca stereo di ingresso linea.

USCITA LINE OUT

Connettori pin-rca di uscita linea (pre-
fader master) utilizzabili per la registrazio-
ne o per inviare il segnale in uscita ad
un’altra unità.

USCITA SLAVE OUT

Connettore pin-rca di uscita linea (post-
fader master) per inviare il segnale in usci-
ta ad un’altra unità.

USCITE A MORSETTIERA

È possibile connettere diffusori passivi con
impedenza totale di 8

, collegando il termina-

le “-” del diffusore al terminale “COM” dell’am-
plificatore e il terminale “+” del diffusore al ter-
minale “8

” dell’amplificatore; oppure si posso-

no connettere diffusori con trasformatore di
linea a tensione costante (100V), collegando il
terminale “-” del diffusore con il terminale
“COM” dell’amplificatore e il terminale “+” del
diffusore con il terminale “100V” dell’amplifica-
tore. La somma delle potenze dei diffusori con-
nessi non deve superare la potenza di uscita
massima dell’amplificatore. È sconsigliabile col-
legare contemporaneamente diffusori a bassa
impedenza e diffusori con trasformatore di linea
a tensione costante. Fare attenzione che non si
verifichino cortocircuiti sulle connessioni.

MONTAGGIO SU RACK 19”

Con l’amplificatore vengono fornite in
dotazione due staffe per il montaggio del-
l’apparecchio su rack 19”.

PRIORITY SELECTOR

Selector to enable “priority” function on
MIC1. When selector is ON, MIC2,
MIC3/AUX, LINE levels automatically lower
(attenuation -40dB) with signal on MIC1
input.

PHANTOM SELECTOR

When this button is pressed, phantom
power (+21VDC) on MIC1 is activated.

MIC2 INPUT

Unbalanced mono jack microphone input
connector.

MIC3/AUX INPUT

Microphone input or unbalanced line
input, selectable.

MIC/AUX SELECTOR

Selects microphone (MIC) or line (AUX)
MIC3/AUX input.

LINE IN INPUT

Line input stereo RCA connectors.

LINE OUT OUTPUT

Line output RCA connectors (pre-master
fader) usable for recording or to send out-
put signal to another unit.

SLAVE OUT OUTPUT

Line output RCA connector (post-master
fader) to send output signal to another
unit.

TERMINAL BOARD OUTPUTS

It is possible to connect passive loud-
speakers for a total impedance of 8

by con-

necting the “-” loudspeaker terminal to
amplifier “COM” terminal and “+” loud-
speaker terminal to “8

” amplifier terminal;

or it is possible to connect constant voltage
(100V) line transformer loudspeakers con-
necting “-“ loudspeaker terminal with ampli-
fier “COM” terminal and “+” loudspeaker ter-
minal with amplifier “100V” terminal. Total
connected loudspeaker power must remain
within the amplifier’s maximum output
power. It is not recommended to connect low
impedance loudspeakers and constant volta-
ge line transformer loudspeakers at the same
time. Avoid carefully short circuits on the
connections.

19” RACK MOUNTING

Two 19” rack mounting brackets are sup-
plied with the amplifier.

SELECTOR PRIORITY

Selector para activar la función “priority”
en MIC1. Cuando el selector esté en ON,
los niveles de MIC2, MIC3/AUX, LINE bajan
automáticamente (atenuación -40dB) en
presencia de señal en la entrada MIC1.

SELECTOR PHANTOM

El pulsador apretado activa la alimenta-
ción phantom (+21VDC) en la entrada
MIC1.

ENTRADA MIC2

Conector jack mono de entrada microfóni-
ca no balanceada.

ENTRADA MIC3/AUX

Conector jack mono de entrada microfóni-
ca o de entrada línea no balanceada, selec-
cionable.

SELECTOR MIC/AUX

Se utiliza para seleccionar si la entrada en
MIC3/AUX es microfónica (MIC) o de línea
(AUX).

ENTRADA LINE IN

Conectores pin-rca estéreo de entrada
línea.

SALIDA LINE OUT

Conectores pin-rca de salida línea (pre-fader
master) utilizables para la grabación o para
enviar la señal en salida a otra unidad.

SALIDA SLAVE OUT

Conector pin-rca de salida línea (post-
fader master) para enviar la señal en sali-
da a otra unidad.

SALIDAS DE CAJA DE BORNES

Es posible conectar difusores pasivos con impe-
dancia total de 8

conectando el terminal “-“

del difusor al terminal “COM” de la etapa de
potencia y el terminal “+” del difusor al termi-
nal “8

” de la etapa de potencia; o se pueden

conectar difusores con transformador de línea
de voltaje constante (100V) conectando el ter-
minal “-“ del difusor con el terminal “COM” de
la etapa de potencia y el terminal “+” del difu-
sor con el terminal “100V” de la etapa de poten-
cia. La suma de las potencias de los difusores
conectados no debe exceder la potencia de sali-
da máxima de la etapa de potencia. Se aconseja
no conectar difusores de baja impedancia y de
transformador de línea de voltaje constante a la
vez. Tener cuidado que no se averigüen corto-
circuitos en las conexiones.

INSTALACIÓN SOBRE RACK 19”

Con la etapa de potencia se suministran
dos palancas para la instalación del apara-
to sobre rack 19”.
