Switching A/V Channels
Sine the MX-30 DSP has 4 A/V inputs ,you can switch between them via the INPUT button . Let's say you are performing
live ,and want to do 4 songs back to back ,but they are on different discs! Instead of stopping to switch CD'
S between songs (not very good for live performances),have a disc queued in A/V 2-4,and simply hit the INPUT
button and PLAY ,you are back in action!
Balancing the Music with the Vocals
Have you ever been to a musical performance where the music was so loud that you could barely hear the singer?
Or maybe to a performance where the singer was so loud hat the music was drowned out ? Those situations are
created with poor musical balancing. To avoid these situations ,the PA-1650has a MASTER ,BASS ,MID and TREBLE
control for both the music and the Mic levels .If you find that music is too loud ,simply adjust the MASTER
MUSIC control knob for the music ,Also ,keep in mind that BASS ,MID and TREBLE levels also affect the overall
"sound"and can be adjusted to correct sound balancing problems.
Balancing Microphone Levels
When adjusting Mic levels ,it is recommended to do so in this order:
1)Cut off the Echo and back ground music.
2)First adjust the MASTER MIC control knob to an appropriate level without background music and test.
3)Then balance the BASS ,MID and TREBLE levels for fine tuning .A just these knobs till no feed-back from the MIC.
4)Start background music and adjust each MIC CHANNEL accordingly.
5)Remember to compensate if the background music has striking volume changes.
6)Do a complete song for complete balancing success.
Using Digital Echo
The PA-1650has a built in , adjustable Digital Echo effects processor that can really add a spacious feeling
to the vocals .you can adjust ECHO is several ways .First .you can adjust the overall ECHO applied to the Mic
channels via the DIGITAL ECHO control knob .This limits the echo to all 3 channels together. Once you have your
master ECHO level established ,you can start customizing the nature of the echo via the DELAY and REPEAT
controls .The DELAY knob controls the interval time between each echo and the REPEAT knob controls the # of
times the echo will repeat. By fine tuning these controls .you can start customizing the nature of the echo via
the DELAY and REPEAT controls. The DELAY knob controls the interval time between each echo and the REPEAT
knob controls the times the echo will repeat .By fine tuning these controls. you can achieve the "perfect"
echo effect. Each Mic channel has it's own DIGITAL ECHO VOL knob to adjust echo individually, To add, turn
clockwise ,To remove ,turn counter-clockwise.
