Operation/Adjustment - Linear Power 952 Owner's Manual And Installation Manual

Linear power 952 amplifier owner's manual and installation guide

4. The other end of the fuse holder should be connected to the positive power

wire from the amplifier. To extend the length of the power lead, use 12 gauge

wire or larger to reduce power loss.

5. The red and white wire acts as an electrical switch to turn the amplifier on and

off. It should be connected to the power antenna lead from the radio. Where no

power antenna lead exists, a source of 12 volts, connected through a toggle

switch, will do. Do not connect the red and white wire directly to a source that will

leave the amplifier permanently on as this will drain the battery.

6. The RCA (Phono) jacks will accommodate either high or low level signals,

ranging from 150 mV to 5 Volts. For low-level signals, always use shielded cable

and avoid routing signal cables in the vicinity of any power wires. The center pin

of the RCA plug is always the positive input connection. With the connector end

of the amplifier facing you, top side up, the connections are LEFT and RIGHT.

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 the

amp 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 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

source up until it just starts to distort, then back down slightly. This is the point

where the output of the source is cleanest. Now, bring the gain of the amp up

until it just starts to distort and back down slightly. This will allow the source and

amp to reach maximum usable output at the same time.

TWO-OHM CAPABILITY

The Model 952

amplifier is two-ohm capable. In order to make the 952

two-

ohm ready, the main power fuse must be removed and the bottom cover slid

open. Inside on the circuit board you will find two jumper wires attached to lugs

marked 4 ohms. Remove the jumpers from the 4-ohm lugs and press them firmly

back onto the lugs marked 2 for 2-ohm loads ohms. Replace the bottom cover

and main power fuse. Your 952

is now ready to operate into a 2-ohm load per

channel.
