K45-SPLT
Figure 3 – K45 Audio Splitter cabing example
Here we have connected the K45-SPLT to accept audio input from a receiver (cable marked AF)
and splitting it between a K45 AF input and and an external speaker. Since the receiver output is
mono and is feeding a mono speaker, we set the switch to M for mono. If the receiver output was
stereo and we were feeding a set of stereo headphones, we would set the switch to S (stereo).
Note that the connection to the K45 is very simple, just one cable from K45-SPLT J2 to K45
Audio Input.
In general, the stereo switch position is used mostly when the audio destination is a set of stereo
headphones. Most modern receivers headphone jacks are formatted in right and left outputs with
both channels being the same. This will work fine with the K45 splitter set set to stereo.
An external speaker jack may or may not be stereo, if it's mono set the switch to mono and it will
work fine driving a mono speaker.
The K45 audio input takes audio from tip and sleeve and ignores the ring so this works fine with
the switch set either way.
