<strong>Lexicon</strong> <strong>480L</strong> Owner's Manual<br />
Solving Problems<br />
When I try to use a cartridge, the <strong>480L</strong> tells me that the<br />
cartridge is not formatted.<br />
Before a cartridge is used for the first time, it must be<br />
formatted. While this is generally done at the <strong>Lexicon</strong><br />
factory or by your dealer, it is possible that you have<br />
obtained an unformatted cartridge.<br />
To format a cartridge:<br />
1. Press CTRL to enter the control mode.<br />
2. Press PAGE, 2 to go to page 2.<br />
3. Use the FUN slider to select the format function.<br />
4. Hold down STO and press REG to format the<br />
cartridge.<br />
Important! A cartridge cannot be formatted if the<br />
register protect function is activated, or if the<br />
cartridge's memory protect switch is ON.<br />
My <strong>480L</strong> was just upgraded to a new software version,<br />
and my cartridges no longer work.<br />
Some (but not all) software improvements may be<br />
incompatible with cartridges formatted with older software.<br />
To make a cartridge usable again, it must be<br />
reformatted as described above. This will erase the<br />
old contents of the cartridge.<br />
When connected to the effects loop on my console,<br />
turning up the console's effects send and returns just<br />
makes the dry signal louder--I don't hear any effects<br />
from the <strong>480L</strong>.<br />
Assuming that your system is wired correctly, the<br />
problem is probably that the Wet/Dry Mix control on the<br />
registers you are using has been set to 100% dry. Set<br />
it to 100% wet and try again.<br />
LARC displays "Mainframe Link Failed" message.<br />
When you first power up, all four indicators on the Host<br />
card should light up momentarily, and then go off. If<br />
they don't, contact <strong>Lexicon</strong> Customer Service. If ROMs<br />
have been changed recently, make sure all pins are<br />
inserted in their sockets correctly. Make sure that Host<br />
board is correctly seated in its socket. Make sure the<br />
LARC cable is correctly connected. Check line voltage.<br />
Inadequate line voltage will prevent the <strong>480L</strong> from<br />
powering up normally. Finally, check to see if a LARC<br />
port has been accidentally connected to the automation<br />
port. Connection of a LARC port to the automation<br />
port will blow an internal power supply fuse and shut<br />
down the <strong>480L</strong>.<br />
My <strong>480L</strong> loses register contents.<br />
The most likely cause is dead batteries on the Host<br />
card. Contact <strong>Lexicon</strong> Customer Service for information.<br />
Another possibility is a blown fuse. The LARC<br />
fuse is accessed by removing all of the cards. There are<br />
two fuses on the backplane. The lower fuse is the<br />
automation fuse and the upper fuse is the LARC fuse.<br />
The automation fuse is currently unused, and can be<br />
used as a spare LARC fuse. The power supply fuses<br />
are inside the unit and can only be accessed by<br />
removing the top cover. The +5V power supply fuse is<br />
on the left side of unit, and the +15V power supply<br />
fuses are near the rear.<br />
My <strong>480L</strong> cannot run more than one program at a time.<br />
Whenever I try to control Machine B, the message "Not<br />
enough HSPs" appears.<br />
There are four possibilities. Your machine is missing<br />
one HSP board (two are required to run two programs<br />
simultaneously); one of the two HSP boards is not<br />
seated correctly; or one of the two HSP boards is<br />
malfunctioning. Finally, you may be attempting to run a<br />
program (such as the stereo sampler) which can only<br />
run when the <strong>480L</strong> is in the SINGLE configuration.<br />
I tried to use Digital I/O, and it is extremely noisy and<br />
distorted. Sometimes it doesn't work at all.<br />
In the course of shipment the phase locked loop (PLL)<br />
may have become misaligned. With external word<br />
clock connected and selected, use a small insulated<br />
screwdriver to adjust the trimmer capacitor on the far<br />
right hand side of the Host Card until undistorted audio<br />
passes. Find the extremes where the PLL goes out of<br />
lock, and then set the pot for the center of this range.<br />
If this fails to correct the problem, but the status slider<br />
indicates that external word clock is present, you may<br />
have excessive noise in the digital interface. This<br />
problem should be referred to a qualified service technician<br />
for diagnosis and correction.<br />
