This note will discuss DC Power sources and how they relate to 12 volt
products .
General Specifications
Our general specification for the voltage range of operation is 10 to
16 volts DC .
Voltage
The voltage of a fully charged battery ( engine not running ) is
approximately 12.5 VDC. Once a load (items being powered represent the
"load" ) is applied , the voltage will drop. How much the voltage is reduced will
depend on the following:
1. Current draw (amount of amperage) The higher the draw the
greater the voltage will drop.
2. The size and length of the conductor (wire) supplying power.
Converters
Many boats incorporate convertors as a source for 12VDC when
connected to shore power (110-120 VAC). Some converters put out a very
clean DC supply where others may have a considerable amount of AC
ripple noise under maximum load.
This AC ripple noise is filtered by the boat battery when connected
into the circuit, but when the battery is disconnected the amount of AC
ripple noise can create major problems for audio products. Noise may
result and the line fuse may fail .
APPLICATION NOTES
4 SPEAKERS, WITH FADER
Negative (- ) ground connection (black)
Connect to the car chassis ( - ) via the black connection lead.
Note: Ground over antenna socket is not sufficient.
( + ) 12 volts battery / permanent / memory (Orange)
Connect to uninterrupted positive supply, terminal (behind the
car fuse) via the connection lead.
( + ) 12 volts/ power line (RED)
Connect the connection cable to fuse holder terminal (switched
by the ignition switch) or to uninterrupted positive supply termi-
nal (behind the fuse).
Connection for External Amplifier (white / red) (OPTION).
Using these connections an additional amplifier may be
connected.
