1. POWER button - This button turns the DA-900 ON/OFF.
2. 10-BAND GRAPHIC EQ - This GRAPHIC EQ is used to BOOST and/or CUT particular frequencies from SOURCE MUSIC output. Each slide fader
process' a particular frequency range indicated by the number above it. Frequencies from 30Hz - 120Hz constitute the very low to low range. Frequencies
from 120Hz to 1kHz are the mid-range and frequencies from 1kHz to 16kHz make up the high to very high range. To adjust slide the fader up to boost the
frequency presence and down to cut the frequency presence.
3. SPECTRUM GRAPHIC analyzer - This displays a GRAPHICAL representation of the master AUDIO OUTPUT and FREQUENCY levels. Use this
display to MONITOR your AUDIO OUTPUT signal for sound quality assurance. As with the graphic EQ, each LED bar represents a particular frequency
range indicated by the number above it.
4. INPUT SOURCE buttons - These buttons select devices connected to the (DVD) and (CDG) AUDIO INPUT channels for active audio playback. For
example, let's say you have player A connected to the DVD channel and player B connected to the CDG. If you wanted playback from player A, you
would press the DVD button and for player B, the CDG button.
5. PINK NOISE button - When pressed, this button generates a PINK NOISE signal that is routed through the AUDIO OUTPUTS to connected devices.
This is designed for quick and easy testing that the DA-900 is outputting a signal to external devices. NOTES: To test sound quality, it is recommended to
use a media track or microphone rather than the pink noise generator. It is recommended to keep the master volume on the DA-900 and external
amplifier to a moderate level suitable for signal transfer.
6. EQ MODE ON/OFF buttons - These buttons turn the EQ off and on.
7. DISPLAY MODE control - The SPECTRUM display can be REVERSED for different metering needs and techniques. Press NORMAL for standard
metering, and REVERSE for reverse metering.
8. EQ DISPLAY fader - The SPECTRUM display's graphic leveling can be adjusted for INCREASED or DECREASED peak valuing. Slide fader up to
INCREASE and DOWN to decrease.
9. DELAY fader - The DELAY fader adjusts the length of each echo interval with ECHO is applied. As more DELAY is applied, there will be more "space"
between the starting and ending point of each echo interval prior to fade out. Slide upward to increase DELAY and downward to decrease DELAY.
10. REPEAT fader - The REPEAT fader adjusts the number of echo repetitions prior to fade out by adjusting the echo interval's full-cycle time. As more
REPEAT is applied, more echoes will occur prior to fadeout. Slide upward to increase REPEAT, and downward to decrease REPEAT.
11. MIC 1-2 ECHO faders - These faders adjust the level of ECHO applied to the MICROPHONE channels 1 and 2 individually. Slide upward to increase
VOLUME, and downward to decrease VOLUME.
12. MIC 1-2 VOLUME controls - These controls adjust the VOLUME levels for MIC channels 1 and 2 individually. Turn clockwise to increase VOLUME,
and counter-clockwise to decrease VOLUME.
13. MIC 1-2 INPUT jacks - These ¼" MIC jacks are for connecting microphones with a ¼" type plug.
14. MIC GAIN/MORMAL button - Activate the MIC GAIN button for a boost to the MIC output. This is handy when singing along with source audio tracks
that differ in volume levels.
15. MASTER VOLUME fader - The MASTER VOLUME fader is the MASTER LEVEL control for the DA-900's OUTPUT. Turn clockwise to increase and
counter-clockwise to decrease MUSIC VOLUME.
