Ramsey Electronics RCA to XLR Converter R2XL1 - Manual (Page 17)

If neither of these methods works and you have a source of RF nearby like a
transmitter, it may be RF causing interference. This is a more difficult problem
to fix, but not impossible. The first thing to do is move equipment away from
the RF source. The next is to put the R2XL1 inside of a metal case. The last
method is to use RF chokes on your audio cables (usually snap-on ferrite
beads of various sizes). You should be able to find these at most electronic
supply stores.
ASSEMBLY INSTRUCTIONS FOR CUSTOM CASE
The enclosure is a key element to the overall pride you will have upon com-
pleting your Ramsey kit. The enclosure will show how you were able to “build
from scratch” a commercial piece of high-tech electronics. For some of us,
the enclosure will also hide a number of “not-so-pretty” assembly mistakes.
Once the kit is enclosed, your friends will never know that you were new to
soldering. Finally, the enclosure case will protect your electronics from many
possible causes of damage so that you can receive years worth of enjoyment
using, talking about, and remembering the fun you had building your kit. In
short, TAKE YOUR TIME when assembling the enclosure. This is the part that
you and your friends will look at and admire for years!
ˆ 1. Lay the front and rear plastic plates over their corresponding labels to
verify which sticker goes with which panel. You’ll want to work with one
panel at a time to avoid possible mix-ups.
ˆ 2. Remove the backing material from one of the stickers and line it up
properly on its pre-punched panel. Make sure that they are aligned cor-
rectly before allowing them to touch the plastic plates. They stick the first
time; line them up right!
ˆ 3. Use a sharp hobby knife to cut out the holes in the labels along the pre-
punched holes. A short sawing motion works well around the inner circum-
ference of the holes.
ˆ 4. Repeat the above steps for the other panel.
ˆ 5. Insert the board into the case with the knobs and switches extending
through the holes in the front panel.
ˆ 6. Raise the rear portion of the PC board and extend the jacks through the
rear plastic plate. Insert the plate into the grooves on the base tray.
ˆ 7. Secure the PC board to the bottom base tray with 4 short Phillips head
screws.
