Firmware Update Procedure
Redline series products are equipped with user upgradable firmware to accommodate future voicing
and DSP updates. To update the firmware, please follow the instructions below.
Firmware Update on RL12/RL15
1.
Disconnect the unit from AC supply and disconnect all
analog audio cabling.
2.
Remove the 12 mounting screws using a standard Phillips
head screwdriver. Notice the top center screw indicated in
the diagram, this is not a mounting screw, but a jacking
screw location.
3.
If the amplifier remains fixed to the loudspeaker after
removing the 12 mounting screws, it is because the amplifier
to loudspeaker gasket is binding them together. To free
them, use the center jacking location to free the amplifier
from the loudspeaker.
4.
To do so replace the keeper screw from the center location
with one of the mounting screws already removed.
5.
Turn the mounting screw clockwise, pushing against the
loudspeaker and forcing the amplifier’s corner out. If the
amplifier remains fixed to the gasket it may be necessary to
jack another corner away from the loudspeaker.
6.
Once free, carefully lift the amplifier from the loudspeaker
and disconnect the electrical leads at the coupling. Set the
amplifier module aside.
7.
Locate the Micro USB input port at the top of the amplifier
and connect the user supplied micro cable to the amplifier.
8.
Connect AC power to the amplifier module and follow the
firmware update quick start guide.
WARNING: Once AC power is applied to the amplifier
module, avoid direct contact with the protective cage
surround the amplifier.
9.
When the firmware update is complete, disconnect AC power
from the amplifier, disconnect the USB cable, then re-secure
the amplifier module to the loudspeaker.
