JAMO J 110 SUB, User Manual

CONNECTIONS AND CONTROLS

CAUTION: Ensure that the subwoofer is unplugged from the AC wall outlet before making 

any connections. 

“LINE IN” Connection 

- Most of today’s surround receivers (and pre-amplifiers) have 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 LEFT/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. 

WA-2 Port Connection 

- For wireless connectivity of your new Jamo J 110 SUB or  

J 112 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 klipsch.com 

for more details.

Level

 - If your subwoofer is connected to a Subwoofer Output of a surround receiver, 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.

“LOWPASS” Control 

- 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

 - 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 

- When this switch is in the “ON/AUTO/STANDBY” position, the 

subwoofer will automatically turn “on” when it senses a signal. It will automatically go into 

“standby mode” after 15-20 minutes with no signal. When this switch is in the “OFF” position, 

the subwoofer will remain “off” until the switch is manually turned back to the “ON/AUTO/

STANDBY” position.

Power LED indicator

 - Located on the front baffle, this LED indicates the operating status 

of the built-in amplifier. The LED will light green when the amplifier is on and receiving 

a signal. If the LED is dark and not lit, the amplifier is off. For more information on the 

controls mentioned in this manual and on bass management, see your dealer or visit
