Balancing a Microphone Channel
When adjusting Mic levels, it is recommended to do so in this order:
1. First adjust the MIC VOLUME control to approximately 50%. (Shown on Fig. 1)
2. Then balance the LOW, MID and HIGH controls to approximately 40-60%. (Shown on Fig. 2)
3. Start background music with the MUSIC VOLUME set at approximately 50%. (Shown on Fig. 3)
4. Fine-tune each MIC CHANNEL as necessary till you get a clean balanced mix (MIC channels 2 and 3 are
controlled together).
5. Remember to compensate if the background music has striking volume changes. To do this, you can utilize
the +20dB GAIN PAD. The +20dB Gain Pad toggles between a current volume level and boosted gain
volume level. This control can be used to immediately go from one volume level to another by a quick push
of the button.
6. Once all the settings are complete, do a complete song for complete balancing success.
Using Digital Echo
The DA-3600 Pro has built in Pro-Echo circuitry that can be applied to the Digital Echo effect. Digital echo
provides a very spacious feeling to the vocals, however when Pro-Echo is applied, you get a 3-D-like feel with
stereo enhanced echo positioning. You can adjust the ECHO in several ways. First off, you can adjust the
overall ECHO applied to the Mic channels via the ECHO VOLUME control. This limits the echo to all 3
channels together. Once you have your ECHO VOLUME level established, you can control the level of echo
applied to each MIC channel individually by adjusting the ECHO control on each MIC channel (MIC channels
2 and 3 are controlled together). After all the echo levels are set, you can start customizing the nature of the
echo via the HIGH, LOW, DELAY and REPEAT controls. The HIGH (HI.) and LOW (LO.) controls adjust the
levels of high and low frequencies applied to the echo processed signal. The DELAY control adjusts the
interval time between each echo, while the REPEAT control adjusts the # of times the echo will repeat prior to
fading out. To toggle the PRO-ECHO and normal DIGITAL ECHO effects, use the PRO-ECHO/ECHO button.
Set the PRO-ECHO/ECHO button to its outer position to apply the PRO-ECHO effect and press the PRO-
ECHO/ECHO button to its inward position to use the normal DIGITAL ECHO. By fine tuning these controls,
you can achieve the "perfect" echo effect.
