Now that your speakers are connected, it is time to connect your audio input devices. Looking at the rear panel 

of the DTX-9900K you will notice several jack groupings. Below we will cover which devices are suited for 

connection, and how the connections are made.

Analog Source Connections

The analog input channels are located between the digital channels and the speaker outputs. Each analog input 

channel has a L/R audio and a corresponding video jack. There are four analog input channels, one analog 

output channel and one loop channel (no video) available for connection. Connections are to be made via RCA-type 

patch cables, preferably shielded to minimize the possibility of cable noise.

Input Connections

To make an analog connection, connect the left and right AUDIO OUTPUT jacks of the external device, such as a 

CD+G or VCD player, to the left and right AUDIO INPUT jacks of the receiving channel on the DTX-9900K. If 

connecting video, connect the VIDEO OUTPUT jack of the external device to the yellow VIDEO INPUT jack on the 

same channel you connected the audio to.
