Output Connections
Use the OUT jacks for feeding A/V to an external device such as a mixer, recording device, second amplifier
and/or television.
To make the connection, connect the left and right AUDIO INPUT jacks on the external device to the left and right
OUT jacks on the DTX-9900K. For VIDEO, connect the VIDEO INPUT jack on the external device to the VIDEO OUT
jack on the DTX-9900K.
Loop Connections
An audio LOOP channel is designed to feed the audio signal out of a host device, into an external device, and back
into the host device prior to speaker output. Loop channels are typically used by mixing amplifiers to get external
effects processing applied, such as digital key control or equalization.
To connect an external device to the LOOP channel, first remove the metal LOOP BARS. It is important to store
the LOOP BARS in a safe place when they are not connected, as they are necessary for audio output when no
device is connected to the loop. After removing the LOOP BARS, connect an RCA-type patch cable from the
OUTPUT jacks of your external effects device to the LOOP IN jacks on the DTX-9900K. Connect a second RCA-
type patch cable from the INPUT jacks of your external effects device to the LOOP OUT jacks on the DTX-9900K.
