TROUBLESHOOTING
PROBLEM: I have no audio gain, in fact it only attenuates!
SOLUTION: You will need a voltmeter to check your power. Look at pin 4 of
U1 for +12 volts, and pin 11 for –12 volts. It may not be exactly that voltage,
but +- 0.5 volts if fine. Without power applied the R2XL1 will pass through au-
dio, but not much.
PROBLEM: Sound is very badly distorted.
SOLUTION: You may be using a high level source into the R2XL1 causing it
to overload. Using this to convert from speaker lever to XLR is not recom-
mended but it is possible. Just turn down your volume a bit. Also check that
you do not have the gain up all the way. Lastly, check to make sure your desti-
nation equipment is set up correctly.
PROBLEM: Audio seems noisy or picking up interference.
SOLUTION: Here is where R6 and R12 come into play. The two 560 ohm
(green-blue-brown) resistors that were left out of the normal construction steps
may need to be installed. With long cable runs you are more likely to run into
this type of problem. We left these parts out initially to help increase the over-
all frequency response of the unit and provide you with a much crisper sound.
You may need to install them however to combat the effects of long cable
runs.
(Note to wired and tested customers: By default, these are installed on the
wired and tested versions of the kit already.)
PROBLEM: It just wont work, it must be Ramsey’s fault!
SOLUTION: Look in the warranty section for information how to contact us
and to find out about our free services when it is our fault. We would recom-
mend however that you go through the assembly steps SLOWLY and check
for potential mistakes. If that fails, give us a call and we’ll be happy to help.
