The measurements given above were determined using equipment in the stetsom laboratory.
AUDIO PRECISION APX515 audio an AUDIO PRECISION AUX-0025 passive filter: reference
test at 60hz frequency with THD+N at ≤1%.
Amplifier dyno ad-1 smd: reference test at 40hz frequency with THD+N at ≤1%.
The electronic components and the manufacturing process can vary slightly and cause small
variations in the measurements.
SOUND DISTORTIONS:
▪ The speakers may be overloaded or defective, lower the level and then readjust
the level. This setting can be adjusted as follows:
a)
On the radio/player, play any musical signal and set the volume to 80% of
the maximum (if the maximum volume of the radio /player is 45 (100%), set to 36
(80%).
b)
On the amplifier, begin with the LEVEL control at minimum, increase
gradually until the LED CLIP starts to flash. Slowly decrease the LEVEL until the led
goes out completely.
WEAK OF BASS:
▪ Cables of the speakers may be reversed and (speakers out-of-phase
).
NOISE AND FAILURE IN SOUND:
▪ Make sure that the installation is not close to the vehicle’s
original
wiring
as it may cause interference and noise in the audio signal.
▪ Create a separate power connection for the sound system. Use a fuse/
circuit breaker as close to the battery as possible for protection.
▪ Make a good grounding for the amplifier. To do this, remove the paint
from the vehicle chassis at the desired point. Attach the wire using a ground
terminal. To prevent oxidation, isolate with paint.
▪ Do not loop the ground. Avoid using multiple grounds. If possible, use a
star connection, so all the grounds run from a single point.
