Special Note for Permanent Installation
When installing the RBN™118 Sub, AC power runs will be used and a certified electrician should be consulted
to be sure that all AC wiring complies with local codes and regulations. It is also advisable to use a cable clip
properly affixed to the cabinet to strain relief the IEC power cord connected to the amplifier module at (2) so the
power cord cannot be pulled out or vibrate loose.
OPERATING INSTRUCTIONS
Connecting AC Power To The RBN™118 SUB
The RBN™118 Sub comes with an 6-foot IEC connection AC power cord. If you are using an extension cord
or power strip with this powered speaker, make sure it is of good quality and of a sufficient current capacity to
maintain safety and maximize the power output capability of the RBN™118 Sub. For maximum undistorted out-
put, do not connect any other device to the same extension cord that the RBN™118 Sub is connected to. Do not
exceed the rated current capacity of the extension cord with the sum total of all units connected to it.
When first plugging in the AC cord, make sure the power switch is in the Off position, and then turn it On only
once the power cord has been connected. Built-in muting will engage when the proper sequence of steps is tak-

Use of the RBN™118 SUB with a Speaker Pole
The RBN™118 Sub has a threaded pole mount cup built-in so that the system can stand mount a full-range
speaker on a supplied 1 3/8" (35mm) diameter stand pole with an M20 threaded end.
When using the speaker pole, be sure to follow these precautions:
A.
The pole is rated for use with a speaker that is less than 30 inches high, and less than 50 lbs.
B.
Always place the Sub on a flat, level and stable surface.
C.
Try to route cables so that people will not trip over them, or tip the speaker over. Use of duct tape, cable
channels or guards, or other appropriate tie-down/cover–up devices should be carefully considered and
implemented.
D.
When installing or de-installing the speaker on the pole, it is a good practice to have a helper if possible,
it can be hard to "thread the needle" and mate the full-range speaker stand cup to the Sub pole
while holding the full-range speaker system at arm's length.
E.
When using Subs with poles outdoors, never attach banners or flags to the pole or the full-range speak
ersystem, strong winds may cause the speaker to blow over. If there is a possibility of windy conditions,
then it may be prudent to consider weighting or locking down the Sub to prevent the RBN™118
Sub speaker system from being blown over.
Connecting a Signal to the RBN™118 Sub
There are a variety of ways to input a signal to the RBN™118 Sub.
The inputs (5) provides either a balanced mic- or line-level input, allowing the use of a 1/4" TRS (ring-tip-sleeve)
type phone plug or a male XLR plug.
There is also a 3.5 mm MEDIA IN jack on the Channel 2 input.
The 3.5mm TRS input jack has its own preamp designed for connection to the headphone jack on mobile audio
devices. The Channel 2 Gain control adjusts the signal level from all of the channel 2 input connectors. It is pos-
sible to use both the combo mic or line input and the 3.5mm input by setting the channel 2 Gain control for the
combo input source, and then using the mobile devices headphone volume to adjust its volume.
Note that the 3.5 mm jack mixes a stereo signal down to monophonic, as the RBN™118 Sub is a single sound
source.
Do not connect cables to the jacks while the unit is ON and the Gain knob is turned up! While a standard sin
