Orion COBALT Series Installation Manual

Each amplifier uses a DC switching circuit to multiply the incoming 12 VDC to the higher DC volt¬
ages needed for a high-power design. The switching time is optimized for efficient energy conversion
and minimum radiation of RFI (Radio Frequency Interference). A second-order filter is included in the
design to further reduce any potential interference artifacts.
The amplifier is turned on remotely via the connection on the male plug that inserts into the end
of the amplifier. When properly installed (see Installation, starting on page 16), you'll hear a gradual
level change when you power on the control head unit. Within two seconds, the amplifier will be at
the level you've set on the volume control. With this feature, you have time to judge and adjust the
loudness level without having to experience an immediate sonic blast.
Built into each amplifier are two additional fail-safe features. A thermal protection circuit senses
the temperature of the heat sink and will turn off the amplifier if the unit becomes too hot (see
Trouble-shooting Guide, on page 25). Once the amplifier has cooled down, the thermal protection
circuit will automatically turn the amplifier on again. An external fast-blow fuse, installed in-line with
the positive DCIine (red wire), protects the amplifier from any catastrophic system failures.
Each amplifier also includes a soft-start feature, to minimize turn-on "thump". Protective monitor
circuits in the output stages will shut down the amplifier in case of a speaker failure or a short circuit
in speaker wiring.
