Setup
One cable is provided with your SP4 to connect it to a K4 transceiver as described under Monaural Setup with
One SP4 below. The SP4 connectors accept standard two-circuit (stereo) audio cables with 3.5 mm male
connectors.
Monaural Setup with One SP4
 Connect the SPKRS jack on the K4 rear panel to either the INPUT A or INPUT B jack on the SP4 using
the stereo cable provided.
 If you have a second K4, use a second stereo cable to connect it to the remaining input at the SP4.
 Press the front panel switch in to select the audio at INPUT B or press and release it until the button is
out to select audio at INPUT A.
 If you want to listen to both the SP4 and headphones at the same time, be sure your K4 Menu is set to
Speakers + Phones YES and Speakers, External 2. This will allow you to use stereo headphones for
AFX (audio effects) and dual receive (if your K4 is equipped with the optional sub receiver).
 Your speaker audio will continue to be monaural. You can add a second SP4 as described below to
obtain full stereo output.
Stereo Setup with Two SP4 Speakers
 Connect the main SP4 (left audio) to your K4 as described under Monaural Setup with One SP4 above.
 On the main SP4, plug an audio cable into the OUTPUT to 2nd SP4 jack. We recommend you use the
stereo cable supplied with the SP4 although a monaural cable will work.
 Plug the other end into INPUT A or INPUT B on the second SP4.
 Set the front panel pushbutton switch on the 2nd SP4 to match the input connection you selected.
 Be sure your K4 Menu is set to Speakers, External 2. This will allow you to hear the full stereo effect of
AFX (audio effects) and dual receive (if your K4 is equipped with the optional sub receiver).
You can connect another K4 to the unused input of the second SP4 for monaural listening. Only
audio from the main SP4 can be passed to the second SP4 for stereo listening.
