OPERATION / ADJUSTMENT
The output of most any car audio equipment will follow a common distortion
curve. This curve will show that the distortion is at its lowest level right before it
reaches full rated output. After that point, the distortion increases rapidly to
unusable levels.
For any system to operate at minimum distortion with minimum noise and still
reach full power output, the equipment should all be aligned to operate at the
same point on the curve at the same time.
In a basic system, using a single amplifier, set the amp gain to minimum, turn the
deck up until it just starts to distort, then back the deck down slightly. This is the
point where the output of the deck is cleanest. Now, bring the gain of the amp up
until it just starts to distort, and back it down slightly. This will allow the amp to
reach maximum useable output at the same time.
WARNING
Your new LINEAR POWER™ 502HV
amplifier, when used in conjunction with

many of the efficient speaker systems on the market today, can produce sound
pressure levels that are considered harmful to your hearing.
Exposure to loud music may lead to loss in hearing. This effect may not be
readily appreciated because the damage to hearing is progressive. Those who
are exposed to excessive sound pressure should utilize direct individual
protection in the form of earplugs or earmuffs, which are specifically designed for
noise reduction.
In accordance with the OSHA (Occupational Safety and Health Act) regulations
for noise levels as they relate to the work area, excessive sound pressure is
defined as 115db(a) continuous for any length of time.
We recommend that you exercise restraint while enjoying the performance of this
and other high-powered mobile audio equipment.
MOUNTING
1.The amplifier works best if it is kept as cool as possible. Mount in a position
that allows air to flow freely through the fins. Be sure there is ample space above
the amplifier to avoid trapping heated air rising from the amplifier. The amplifier
should not be mounted upside down. Avoid mounting any amplifier in the dash or
on the firewall to avoid noises being radiated directly onto the case.
2.The case of your amplifier is designed to act as a noise shield. To maintain this
protection, be sure the metal case of the amp does not touch the metal of the
