Connecting loudspeakers
If your source provides bass management, you can use the BM14S LFE input alone
in LFE or SLAVE mode, depending on the management system capabilities. Avoid
double processing if possible.
To connect loudspeakers
1. Connect the subwoofer (see “Connecting a single subwoofer” on page 8).
2. From the subwoofer SAT/SUB output connect a XLR cable to the inputs of the
power amplifier you use for your speakers.
Operation
Switching the subwoofer on
Once you have ensured yourself that all necessary connections have been made, the
subwoofer and the connected components can be switched on.
1. Connect the subwoofer to the mains power.
2. Switch the subwoofer on with the main POWER switch on the rear panel.
The status LED on the rear of the subwoofer will light up red.
3. Select a power mode with the Power switch on the rear panel.
Power modes
• On: the subwoofer is switched on permanently
• Auto
– When a music signal is detected, the internal amplifier is activated
automatically. The status LED on the back of the subwoofer will light up green.
As long as a music signal is available on the subwoofer’s input, it will remain
switched on.
– After 15 to 20 minutes of not sensing any input music signal, the subwoofer will
switch itself to Standby mode automatically. The status LED on the back of the
subwoofer will light up red.
Note: The signals connected to the inputs are provided at the Slave output for
connecting another subwoofer. See page 8 to learn more about connecting
multiple subwoofers.
Note: To switch the subwoofer completely off, set the main POWER switch to the
OFF position.

Dopo essersi accertati che ogni collegamento necessario è
stato effettuato, il subwoofer e le componenti collegate pos-
sono essere attivate.
1. Collega il subwoofer alla presa di corrente.
2. Attiva il subwoofer agendo sull’interruttore POWER del
pannello posteriore; il relativo indicatore LED di stato si
accenderà di colore rosso.
3. Seleziona una modalità di alimentazione tramite il seletto-
re Power, sempre nel pannello posteriore.
Modalità Power
– On: il subwoofer è attivo in modo permanente
– Auto
– Quando un segnale audio viene rilevato in ingresso,
l’amplicatore interno si attiva automaticamente. Il
LED di stato sul pannello posteriore dell’unità sub ap-
parirà di colore verde. Il subwoofer rimarrà attivo no
a quando un segnale risulterà presente in ingresso.
– Se entro un intervallo compreso tra 15 a 20 minuti
non viene rilevato alcun segnale in ingresso, il subwo-
ofer entrerà automaticamente in modalità Standby.
L’indicatore LED di stato del pannello posteriore
apparirà di colore rosso.
Nota:
Per disattivare completamente il subwoofer, imposta l’interrut-
tore POWER in posizione OFF.
Regolare il volume (Gain)
CAUTELA
Segnali con livello elevato!
L’uso di livelli elevati può causare danni all’udito.
– Per evitare i danni all’udito, evita di ascoltare livelli sonori
elevati per periodi di tempo prolungati.

Adjusting the volume (Gain)
The correct volume setting is an important aspect in achieving a well balanced
speaker combination.
To adjust the gain:
Adjust the Gain control, until correct setting is reached.
Selecting the subwoofer cut-off frequency
(Lowpass)
The Lowpass control allows the frequency range of the subwoofer to be defined.
Above the selected frequency the sound level decreases rapidly. The correct setting
of this cut-off frequency is important for a well balanced combination of subwoofer and
speakers.
To selec the cut-off frequency
Set the Lowpass control to the desired frequency between 50 and 150 Hz.
Please also heed the instructions given in the operating manual of your
loudspeakers.
CAUTION
High Sound Levels!
High sound levels can cause auditory defects.
To avoid auditory defects do not listen to high sound levels over a longer period
of time.
Note: You cannot adjust the volume, when subwoofer is in slave mode. In this case
the volume is controlled by the setting of the master subwoofer.
Note: • The Lowpass only works on SAT/SUB input.
• Perhaps subwoofer cut-off frequency is already set in the bass
management of your source. Please refer to the operating manual of
your source. In general use only one bass management system.
La corretta impostazione del volume costituisce un aspetto
importante per ottenere una combinazione bilanciata tra il
subwoofer e i diffusori.
Per regolare il guadagno:
– Regola il controllo Gain no ad individuare un’impostazio-
ne corretta.
Nota:
Non è possibile regolare il volume quando il subwoofer si tro-
va in modalità Slave. In questi casi, il volume viene controllato
dalle impostazioni dell’unità sub Master.
