Unbalanced audio is a signal with a ground reference, usually a center wire with a outer ground, like a RCA jack, or coax cable. The center is the signal (hot) while the outer is the (ground) reference and shield.
Here is the 222 wire diagram showing the input in the unbalanced method.
This could be a 1/8 jack plugged into a computer sound card for example.
When using the control cable Ferrite if the hole is to big try to loop the cable through twice. The ferrite installs on the audio cable just outside the transmitter box.
Part of the BLOX series, this compact adaptor com- bines the L/R line level audio signal from standard consumer audio equipment, and converts it to an XLR balanced mic level output. Additionally, a variable attenuator allows control of the output vol- ume level.
The above can be a useful item, stereo in, then the item mixes your stereo to mono and sends it to an XLR out. Be sure to have an XLR jack handy so you can wire this to the 222

The Inovonics audio processor is a special audio processor made especially for a AM transmitter. It has special circuitry that enables it to drive the transmitter over 100% modulation without distortion, resulting in more range and louder sound. This is called asymmetrical modulation, because this processor allows the audio to be non- symmetrical
Am type audio processor and better ground are the two legal ways to increases the radio range.
