transposes the musical key of your source music. The DOWN button lowers the MUSICAL
KEY a half step each time it is pressed. The NORMAL key resets the MUSICAL KEY back to it’s original key
and the UP button raises the MUSICAL KEY a half step each time it is pressed.
3. VOCAL CANCEL AND VOCAL PARTNER buttons – These buttons activate the MULTIPLEX audio
playback modes that are used to cancel out the guide vocals from multiplexed karaoke
media. During playback of a multiplexed track, press the VOCAL CANCEL button once to remove the guide
vocals. Press the VOCAL CANCEL button a second time to have the guide vocals return to playback.
VOCAL PARTNER also cancels out the guide vocals from multiplexed karaoke media, however the guide
vocals are only removed as long as you are singing into the microphone. When you stop singing into the
microphone, the guide vocals are reintroduced automatically. Press the VOCAL PARTNER once to initialize
the feature, and press a second time to disable the feature.
NOTE: Attempting to utilize this feature with a non-multiplexed track will not work as this
feature is designed to work with multiplexed tracks only.
4. A/V SOURCE button –This button toggles input between devices that may be connected to the CDG and
DVD A/V channels. For input from the CDG channel, press the A/V SOURCE button once.
For input from the DVD channel, press the A/V SOURCE button a second time.
5. LEVEL meters – These LED meters display the overall output level from both the A/V SOURCE and
MICROPHONE channels. When there is red LED activity, the output level is in or nearing a distorted level
and should be monitored carefully if not reduced.
6. MUSIC BASS, TREBLE AND MASTER controls – These controls adjust the BASS, TREBLE and
MASTER VOLUME levels for your source music. The BASS and TREBLE controls adjust the low and high

7. MIC MASTER control – The MIC MASTER control adjusts the overall volume of all microphone output.
NOTE: If you need to adjust the volume level of just one MIC channel in particular, use that MIC’s individual
