Adjusting The Audio Level - Audio Design SoundStream xxx-6500 Bedienungsanleitung

PLANNING AND MOUNTING YOUR SYSTEM
The mounting position of your Amplifier will have a great effect on its ability to dissipate the heat
generated during normal operation. Under normal conditions, the heatsink will dissipate sufficient heat
to avoid thermal shutdown. However please do not install the amplifier in a wooden box or similar device
as this will prevent heat dissipation into the atmosphere.
To achieve maximum advantage of convection air flow in an enclosed trunk, mount the amplifier in a
horizontal position.
Cooling requirements are considerably relaxed when mounting inside the passenger compartment since
the driver will not often allow temperatures to reach a critical point. Floor mounting under the seat is
usually satisfactory as long as there is at least 1 inch of clearance (2.54 cm) above the Amplifier's fins
for ventilation.
A. Select a suitable location that is convenient for mounting, is accessible for wiring.
And has ample room for air circulation and cooling.
B. Use the amplifier as a template to mark the mounting holes. Remove the Amplifier
and drill holes. Use extreme caution, inspect underneath surface before drilling!
C. Secure the Amplifier using the screws provided.
TURNING ON THE AMPLIFIER
The amplifier automatically turns on within a few seconds after remote voltage is applied. If your system
is set-up so that the head unit provides the remote voltage; then it would turn on when your stereo is
turned on. Note that there are alternate means of providing the 1 2 volt remote control signal, including
installing and auxiliary switch.

ADJUSTING THE AUDIO LEVEL

As stated previously, it is important to obtain a close match between the source unit's output voltage
and the amplifier's sensitivity or admittance setting.
1. Use a screwdriver to turn GAIN (MIN / MAX) fully counterclockwise to MIN.
2. Turn the auto sound system's volume control to about one-third of its full range.
3. Adjust GAIN (MIN / MAX) to a comfortable listening level.
4. Turn up the auto sound system's volume control until the sound begins to distort. Then
immediately turn the volume down to a point just before where the distortion began.
Caution: Never turn up the auto sound system's volume control more than needed to
adjust the audio level, more than two thirds of its maximum volume.
5. Adjust GAIN (MIN / MAX) until the sound is at the maximum level you want the amplifier to
produce.
6. Adjust the auto sound system's volume control to a comfortable listening level.
NOTE: Raising the Bass frequency allows higher frequencies to reach the bass speakers while
blocking lower frequencies from midrange speakers. Lowering the Bass frequencies
14
allows lower frequencies to reach the midrange speakers while blocking higher frequencies
from bass speakers.
