Setting System Volume
After completing the system wiring, follow the steps below to properly adjust the
EQS744.
1. Turn the master control volume on the EQS744 and the amplifier gain controls
to their minimum setting.
2. Turn the source unit on and increase the volume until distortion is heard, then
reduce volume just below this point. * Once the source unit volume has been
set, it will no longer be used. Always use the volume control on the EQS744 as
the master (main) volume control. It has better electronics, higher S/N ratio
and is more linear than any source unit volume available.
* This is the maximum usable musical signal for the source unit. Turning the volume beyond this point will
increase noise and distortion without an increase in musical signal
.
Setting Equalizer Controls
The EQS744 provides a graphic adjustment band for each of seven frequency
ranges: sub, low, mid, mid-high and high frequency. The center frequency of each
band is adjustable to allow fine tuning of the acoustical response of the vehicle.
1. Begin by setting the SUB/LO/MID/MID-HIGH/HIGH frequencies at the
center position.
2. Play a favorite music track and adjust individual EQ controls to a desired taste.
Avoid extreme settings which can distort musical peaks.
3. Increase or decrease the Equalizer Gain Controls as necessary.
4. If your system includes a subwoofer, slowly increase the Subwoofer control
until you hear solid bass.
5. If your system includes rear speakers, adjust the Fader control to add rear
sound. Set it to so most of the music comes from the front and only fills the rear.
Setting the Low Pass Frequency
The EQS744 provides a built-in Low Pass Crossover, located on the top panel of the
unit. Set at 60Hz or 90Hz depending upon type and size of your subwoofer system.
AUXILIARY INPUT
The EQS744 has a built-in auxiliary input that allows use with portable devices
(such as MP3 player) or a video system.
1. Plug the auxiliary source into the auxiliary RCA input.
2. With the auxiliary switch in the main position, turn the equalizer volume
control to a normal listening level.
3. With the auxiliary source in the play mode, switch to the auxiliary source..
4. Adjust the auxiliary input gain controls, located on the top panel of the
EQS744, so that the volume of the auxiliary source matches the volume of the
main source.
