SPEAKER OUTPUT
The speaker output connectors on the
LP2075©
are two pairs of 5-way binding posts. Attach a
lead from the positive terminal of the speaker to the left speaker positive terminal of the amplifier,
and the negative speaker terminal to the left negative terminal of the amp, repeat for the right
channel. The 5-way binding posts should have a red color band for positive and a black color
band for negative. The speaker terminal, with the terminals facing you, fins up, from left to right, is
as follows:
Left speaker (-), Left speaker (+), Right speaker (-), Right speaker (+)
For Bridging the
Left (+)
and the
Right (-)
are used. All the terminals are also marked on the end
of the amplifier.
GAIN ADJUSTMENT
In a basic system, using a single amplifier, set the amp 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 deck and amp to reach maximum useable output at the same time.
WARNING
Your new
LINEAR POWER™
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 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
115 db
(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.
GENERAL TROUBLESHOOTING
NO SOUND:
Check all connections. Check main power fuses. Check internal fuse(s). Check LED
status indicators, is the Green LED lit? Are any of the other LED indicators lit? With a trouble light
or DVM meter, be sure +12V is present at the amplifier on the large positive cable and on the
small red/white turn-on wire. Check for a good ground connection. Check by substitution or other
method for proper operation of music source. Be sure the
Turn on Switch
mode is in correct
position.
BLOWS FUSES:
Check all connections to be sure all power wires, ground wires and speaker
wires do not short to each other or ground to vehicle. Re-check polarity of main power wires.
Check for proper speaker impedance. Check for proper sized fuse(s)
DO NOT install oversized
internal fuse(s)!
