Connections And Controls - JAMO C 910 SUB Mode D'emploi

CONNECTIONS AND CONTROLS

CAUTION: Unplug the subwoofer from the AC wall outlet before making any connections.
"LINE IN" Connection - Most of today's surround receivers (and pre-amplifiers) have
1
a line level subwoofer output labeled Subwoofer Pre Out, Sub Out, SW Out, etc. If you have
this output, connect one end of a subwoofer cable to it and connect the other end of the
cable into the subwoofer line input labeled L/LFE. This connection allows the subwoofer
to operate with both music and surround sound movies (refer to your receiver manual). In
absence of a subwoofer output on your receiver, as an alternative hookup, you can connect
Left and Right channel Pre-Amp Outputs from your receiver (if provided) to the Left/LFE
and Right input on the subwoofer.
VOLUME - If your subwoofer is connected to a Subwoofer Output of a surround receiver,
2
first set the subwoofer volume level control in the receiver to the "half way" or "0 dB" position.
Then increase the volume (or gain) of the subwoofer up until the subwoofer's volume level
matches the output of your main speakers. After this setup is completed, the volume control
on your system's main amplifier or pre-amplifier will be the volume control for both your
subwoofer and speakers together. If your subwoofer is connected to the L/R Pre-Amp Outputs
of a receiver there will be no subwoofer volume in that receiver to set before setting the
subwoofer's gain control.
CROSSOVER FREQUENCY - 3 The crossover point chosen determines where low bass
frequencies are "handed off" from the speakers to the subwoofer. If setting the crossover
point in the receiver, turn the Lowpass Filter knob on the subwoofer to the farthest point
right (160Hz). Set the crossover point based on the size of the main left/right speakers
you are using in the system. As a general rule, for larger, floorstanding speakers, set the
crossover point between 50Hz-90Hz. If using small bookshelf or "satellite" speakers for the
mains, set the crossover point between 90Hz-150Hz. The smaller the speaker, the higher
the setting until the bass frequencies blend well between the speakers and your subwoofer
once your system is completely hooked up. If your receiver does not have a crossover point
setting, set the Lowpass Filter on the subwoofer instead within the same recommended
settings (see receiver manual for additional speaker setup info).
"PHASE" 0/180 - 4
This control is used to acoustically match the subwoofer's output
to your main speakers. Select the position, either 0° or 180°, in which your subwoofer has
more output at the listening position.
"POWER" AUTO/ON/OFF -
5 In the "On" position, the subwoofer will automatically turn
on when it senses a signal. It will automatically go into standby mode after 15 minutes with
no signal. When this switch is in the off position, the subwoofer will remain off until the
switch is manually turn back to the ON position.
WA-2 Port Connection - For wireless connectivity of your new Jamo Concert 910 SUB
6
orConcert 912 SUB, the optional WA-2 is available. The WA-2 will only operate with select
Klipsch, Energy, Mirage and Jamo brand subwoofers that have a "WA Port" input. The WA-2
is a 2.4 GHz product designed to wirelessly transmit a signal up to a 50 foot radius. See
jamo.com for more details.
Power LED Indicator - Located on the front baffle, this LED indicates the operating status
of the built-in amplifier. The LED will light blue when the amplifier is on and receiving a
signal. If the LED is red, the amplifier is in standby mode. If the LED indicator is not on, the
power to the unit is completely off. For more information on the controls mentioned in this
manual and on bass management, see your dealer or visit www.jamo.com
