3. About the Speakers
The NX4 incorporates two different types of loudspeakers. The front speaker is a high efficiency
horn with maximum sensitivity in the frequency range necessary to reproduce small animal
distress sounds. Distress sounds of rabbits, small rodents, birds, canines, and many others are
best reproduced by using the front horn only with the rear cone speaker turned off. This will
also ensure maximum battery life, as playing both speakers requires almost twice as much
battery power.
The rear cone speaker is best suited for sounds that have significantly lower frequency content.
These sounds include bear growls, mountain lion roars, certain owl hoots, and some other large
mammal sounds. The rear speaker, however, is not as efficient as the front horn. Because of
this, it will not play as loud as the horn. Understand that not all calling sounds will benefit
greatly from playing both speakers at once. If you elect to do this, remember that battery life
will be reduced.
3-1 Using External Speakers
The NX4 is equipped with two external speaker jacks, which allows you to connect up to two
additional speakers. The internal speakers perform admirably, however, you may encounter
situations that require higher volume levels. By connecting a larger and more efficient external
speaker(s) to the NX4, the volume level can be increased greatly.
The external speaker jacks on the NX4 accept standard 3.5mm plugs. When selecting an
external speaker, it is recommend to use one with an impedance rating of 8-ohms. Visit the
FOXPRO®website for a complete line of speakers compatible with this model.
3-2 Connecting External Speakers
Before connecting an external speaker, make sure that the NX4 is turned off!
To connect an external speaker, plug the connector end of the external speaker into one of the
external speaker jacks. If you wish to have only the external speaker(s) produce sound, you
must disable the internal speaker(s) as they are not disabled automatically.
3-3 Disabling the Internal Speakers
Move the speaker slide switch to the “Off” position for the desired speaker you wish to disable.
To enable the speaker again, simply move the slide switch to the “On” position. By disabling the
internal speaker(s), battery life will be extended longer than having all of the speakers operating
at once.
