Connecting the Resound Sub woofer

Choosing the Correct cables
The Resound series speaker connections are made via the rear panel 1/4-inch and/or Neutrik Speakon® connectors.
Standard unshielded speaker wire, available at your local pro audio or music store, with either 1/4-inch phone or
Speakon connectors (wire gauge of 12-14 is recommended).

If your amplifier uses binding posts, you can use speaker cables with banana plugs, but be sure to pay attention to the
plus and minus polarity when making the connections. It is important that your PA system is connected in phase, other-
wise you will not have the proper low-end response and stereo image.

In order to ensure that your PA system is in phase, be careful to pay close attention to the positive and negative marking
on the amplifier and wires. Make sure that the + terminal of the speaker, or banana connector, is connected to the + ter-
minal of the power amplifier and that the - terminal of the speaker, or banana connector, is connected to the - terminal of
the power amplifier. For a detailed wiring diagram, see page 42 of this manual.

About Impedance
Before you hook up your speaker cabinet, be sure that you understand a little about impedance. Impedance is the elec-
tronic load that the speaker puts on the power amplifier and is measured in Ohms.
tronic load that the speaker puts on the power amplifier and is measured in Ohms.
Here is the tricky, yet simple rule of impedance: When two speakers, of equal impedance are wired in "Parallel", like when
you use the Extension Output, the total impedance is cut in half and when two speakers are wire in “Series”, (usually for
internal cabinet wiring only), the total impedance is the sum of the speakers individual impedance.

Each of the Resound models, EXCEPT the RS15S, RS18S and RS215 is 8 Ohms. So, when two Resound models, EXCEPT
the RS215, are connected together in parallel, the total impedance is 4 Ohms. The RS215 impedance is 4 Ohms. So, when
two RS215’s are connected together in parallel, the total impedance is 2 Ohms. The impedance of your speaker also has
an effect on your amplifier. In general, the lower the impedance, the more power your amplifier will put out.

IMPORTANT NOTE: There is minimum safe impedance for running power amplifiers so be sure to check the manufactur-
er’s recommended impedance for your amplifier to avoid any damage to your amplifier or voiding your warranty.

Using the EXTENSION Output
The Resound models provide a convenient Extension Output for connecting additional speaker cabinets in parallel. Be
sure to read the section above on impedance to insure a proper hook up with your amplifier. To connect two Resounds
using the Extension output, connect your amplifier output to the Input of the first Resound and then, connect the
Extension Output to the Input of the second Resound.

Powering the Resound
Each of the Resound loudspeakers have a specific power rating, which is printed on the input jack-plate, and also, in the
Specification section on page 12 of this manual. Be sure to check that your power amp has the correct power output for
your Resound. Be careful to consider the total impedance if you are connecting more the one Resound to one side of a
stereo power amplifier. Using a power amplifier with too low of a power rating can be dangerous since the output signal
is often clipped in an effort to get the desired level. Over powering the Resound can result in catastrophic failure and
therefore using any amplifier with a power rating over the recommend power rating may void your warranty.
