Listening For A Lifetime
Selecting fine audio equipment such as the unit you've just purchased is only the start of your musical enjoyment. Now it's
time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic
Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a
safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most
importantly, without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing 'comfort level' adapts to a higher volume of sound. So what sounds
'normal' can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level
BEFORE your hearing adapts.
To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and clearly, and without
distortion.
Once you have established a comfortable sound level:
• Set the dial and leave it there.
• Pay attention to the different levels in various recordings.
Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for
a lifetime.
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud
noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association's Consumer
Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for
your protection.
Some common decibel ranges:

NOTE: The DA-900 can be used with 110V-120V and 220V-240V power supplies. Please set the VOLTAGE SELECTOR to match your AC power
supply. If plugged into a AC power outlet with the VOLTAGE SELECTOR set improperly, the DA-900 may malfunction, possibly to the point of
system failure. In this case, the product warranty would become void.
(b) Turn on power to all connected external devices.
(c) If dealing with VIDEO, be sure your TV is set to receive video input from the source player's VIDEO OUTPUT jack. (Some TV's use a VIDEO INPUT,
AUX or CHANNEL 0 as a "dedicated" video channel). Check you TV's instruction manual to see how it selects its video channel(s).
(d) Turn on the power to the DA-900.
Sound Check
(a) Select the correct input on your amplifier. For example, if the LINE OUTPUT from the DA-900 is connected to the LINE 1 INPUT on the amplifier, set
the amplifier's INPUT CHANNEL to LINE 1.
(b) Set the MASTER VOLUME control on amplifier to moderate level for testing and adjust the MUSIC E.Q. as desired.
(c) Set the DA-900's MIC 1-2 VOLUME controls to 50% and set the MIC E.Q. as desired.
(d) Set the DA-900's INPUT SELECTOR to the correct channel that a source player is connected to. For example, if you wish to play from the player
connected to the DVD input channel, press the DVD button.

Customizing Source Music Output
To get your SOURCE MUSIC to sound just how you want it, use the MUSIC EQ. It's 10-band design provides detailed frequency adjustments. The
MUSIC EQ does not have to be adjusted every listen. Rather, it should be adjusted when room acoustics, environments, performers, source music or
other significant factor changes, causing a loss in sound quality and balance. Here are some common uses for adjusting the different frequency settings:
30Hz - This range is commonly used to adjust the very low SUB-BASS frequencies that form bass traps in bad acoustical environments.
60Hz - This range is commonly used to adjust SUB-BASS frequencies from subwoofers.
120Hz - This range is commonly used to adjust the MID-LOW BASS frequencies from musical instruments.
240Hz - This range is commonly used to adjust UPPER-MID BASS frequencies that either increase definition of bass or reduce a bass signal's
"muddiness".
480Hz - This range is commonly used to increase or decrease the "presence" of vocals in a mix.
1kHz - This range is commonly used to adjust the "color" of speech in spoken word and other similar source ranges. The more allowable
frequencies in this range, the more definition.
2kHz - This range is commonly used to adjust the attack or "snap" of percussion instruments. The less allowable frequencies in this range, the
less attack.
4kHz - This range is commonly used to adjust the higher frequencies in outdoor environments where rapid loss of those frequencies occur.
8kHz - This range is commonly used to adjust the sibilance of speech. Sibilance includes the sharp "sssss" sounds of pronunciation that can be
annoying when occurring repeatedly at high volumes or in closed, reflective quarters.
16kHz - This range is commonly used to adjust the level of "air" in audio output. Too much "air" results is "hiss", so be careful when adjusting.
To adjust frquencies, slide the faders up to boost the frequency presence and down to trim the frequency presence.
Customizing Digital Echo Settings
When using Digital Echo, you can customize the effect by adjusting the ECHO, REPEAT and DELAY controls. First set the ECHO level control to 5.
Then customize the effect with the REPEAT and DELAY level controls. REPEAT adjusts the interval repetition of the echo effect. As more REPEAT is
applied, more echo intervals will be heard when using it and vice versa. DELAY adjusts length of each interval. As more DELAY is applied, there will be
more "space" between the starting and ending point of each echo. When the Digital Echo effect is customized, adjust the ECHO level control as you
would a master level control.

Customizing Microphone Output
1. Set the MIC 1 and MIC 2 sliders to their center positions.
2. Make adjustments to the 540Hz and 1100Hz MIC EQ sliders for fine-tuning "vocal presence". The 60Hz and 2200Hz sliders are also available for
adjustment of very low/high frequencies in the MIC OUTPUT. However, it is recommended not to apply too much TREBLE as that can lead to
microphone feedback.
3. If you know there will be striking VOLUME changes in the MUSIC signal, remember the MIC GAIN button for those times when you temporarily need a
boost..
