POWER CONNECTIONS

Note: Your amplifier can only be operated from a 12- Volt Negative Ground electrical system. If your car was produced before 1970, or if you have any doubts, make sure of the type of electrical system you have before making any connections.

Determine the alternator rating of your car and the current consumption of the car’s other accessories. It may be necessary to upgrade the alternator or to install a sep- erate battery and battery isolator.

For power wiring, use Soundstream power cable or an equivalent premium cable. The plus 12 Volt terminal of the amp should be connected directly to the posi- tive terminal of the vehicles battery. Install a fuse in line between the amplifier and the battery using the follow- ing fuse for the respective amplifier:

D-20011	. . . . . . . . . . . . . . . . . . . . . . . . . . 30 AMP
D-l 001 I	, . . . . . . . . . . . . . . . . . . . . . .20 AMP

D-601 I	. . . . . . . . . . . . . . . . . . . . . . . . 15 AMP
	.

If your system is using more than one amplifier, each amp should be fused seperately.

The Ground terminal of your amplifier should be con- nected directly to the automobile chassis with the same gauge wire being used for power. Make sure this wire is as short as possible to prevent noise in the system. A nearby bolt can serve as a ground terminal. Make sure that the wire contacts the chassis, not coated metal or paint. It is important that the ground connection you select have minimal noise resistance to the battery ground post. (A maximum of .l ohm resistance should be present.)

REMOTE POWER=ON CONNECTION

If your tuner/deck has a remote power-on control wire, connect it to the REMOTE terminal on your amplifier. This is a control line, not a power line, so small wire (18-20 gauge) is acceptable.

If your tuner/deck has no remote power-on control labeled as such, but has a power antenna control, it may be possible to wire the power antenna control to the REMOTE terminal.

If your tuner/deck has neither a remote power-on control wire nor a usable power antenna control, it will be necessary either to connect the REMOTE terminal to a 12 Volt source which is switched by the ignition key or to connect the REMOTE terminal to a constant 12 Volt source through an ON/OFF switch you install in series with the ignition switch in a location accessible to the

driver. Note: If an outboard switch is used, make sure it is switched off when you leave the vehicle or when the sound system is not in use otherwise it is possible to run down your battery.

BEFORE POWERING UP THE SYSTEM

To prevent unnecessary labor, proof all your connec- tions for shorts and improper connection. Double check to make sure you have chosen all of the correct ampli- fier settings.

POWERING UP THE SYSTEM

Once the installation is complete, turn on the system. The LED indicator on the amplifier should now be lit. If it did not light up, turn the system off immediately. Proof wiring and check for shorts or poor connection.

If wiring is okay, check the relay or fuse in the power line. If blown, replace it with another identical fuse. Also check the interior power supply fuse. If blown, replace with a fuse of identical value.

INPUT LEVEL ADJUSTMENT

Input levels are adjusted by means of two independ- ent controls located between the heat sinks directly above the appropriate RCA connector, When the amplifier is being operated in the stereo mode both of these adjustments are to be used. When bridged, only the right input control is used.

To set your amplifier levels, begin by turning all level controls to minimum (counter clockwise) Turn the system on, and set the volume on your tuner/deck at its mid- point. Advance the amplifier input level controls until you have reached your maximum desired listening level and both channels are in balance.

LINEAR SUBWOOFER EXTENSION

D-20011 AND CLASS A- 10011

The LSE circuit will compensate for the natural rolloff of most loudspeakers, and can extend deep bass as much as one full octave.

The control allows for continuously variable adjustment over the range from 35 Hz to 280 Hz, of the frequency at which LSE begins its boost. Below the chosen fre- quency, the boost is applied at 6 dB per octave. When properly adjusted, LSE will “linearize” the low end response of the woofer(s) and provide remarkably smooth and deep bass. A word of caution: small inex- pensively constructed woofers may be unable to handle the equalization which results from setting the LSE to above 100 Hz. Also, never activate the LSE circuit while operating the system at high volume. Activate and deactivate with the system off or at a very low level.
