Royer Labs Goes Green!
Royer manufactures RoHS Compliant Products |
Royer
Labs is phasing out the use of lead based solders previously
used in the manufacture of all models of its microphones.
The decision was made to address the health related concerns
that result from the use of lead. All products will bare
a stamp that reads "RoHs Compliant".
Careful consideration was given to this subject long before
RoHS became a buzz issue in our industry. Our engineers had
concerns about conductivity and solder ability of ultra low
impedance ribbon transducers and non-lead based materials.
Fortunately, the new solders that meet the RoHS specifications
actually have higher electrical conductivity properties than
lead based solders
Definitions of RoHS Compliant Products
Pb-free
Mindspeed products that contain ≤ 0.1% lead by weight in homogeneous materials
and can withstand 245C-260C maximum temperature profile per IPC/JEDEC J-STD-020C.
Green (RoHS compliant)
Mindspeed products that contain ≤ 0.1% by weight in homogeneous materials
for lead, mercury, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated
diphenyls ethers (PBDE) and ≤ 0.01% for Cadmium and that meets the recommended
maximum reflow temperature in accordance with IPC/JEDEC J-STD-020C.
Homogeneous Material
Homogeneous material means ‘of uniform composition, examples
are individual types of plastics, ceramics, metals, alloys,
paper, board, resins and coatings and mechanically disjointed
means that materials can be, in principle, separated by mechanical
actions such as unscrewing, cutting, crushing, grinding and
abrasive processes. A semi-conductor package contains many
homogeneous materials i.e. the impurity limit does NOT apply
to entire component.

Royer Labs
will resume inclusion of a complimentary microphone clip
with R-121, R-122, SF-1 and Sf-12 microphones. |
A couple of years ago we discontinued offering a free microphone
clip with certain models of microphones. This was done at the
behest of our customers that felt that the clip we were offering
was not of the same caliber of the microphone. Actually, the
clip was included merely as a means to test the microphone.
Royer always recommended that a proper shock mount be purchased
with the microphone. Unfortunately, some people misinterpreted
the gesture and thought that the mic clip was the
recommended device to hold the microphone. To avoid confusion,
we decided to discontinue including a free clip with the microphone.
Lately we've been getting feedback from our customers asking
us to once again include a mic clip. So we searched for a clip
that would work well, not scratch and be durable. We will resume
including a complimentary mic clip made from virtually unbreakable
composite of ABS and Nylon with all R-121, R-122, SF-1, and
SF-12 microphones.

IMPORTANT
NOTICE REGARDING THE OPTICAL BLACK FINISH OF THE SF-24 MICROPHONE! |
The optical
black finish on the SF-24 microphone is actually a sophisticated
surface treatment designed to refract light rather than
reflect light. The purpose of the optical black finish
and its properties are to make the microphone appear less
conspicuous, especially when used with high intensity lighting
or within a camera shot. The finish requires a certain
amount of maintenance to retain a smooth, even appearance
and to maintain its unique optical qualities.
The
metal components of the microphone's case are comprised
of a low carbon steel alloy. The outer surface is treated
with a special process that is mainly responsible for the
microphone's unique optical properties. The actual finish
consists of black chrome oxide deposited over a nickel
substrate. Together, this process creates a finish that
minimizes the reflective nature of the metal surface. To
protect this finish, a small amount of oil is worked into
the finish at the factory. However, physically handling
the microphone and absorbent materials (like the foam padding
of the microphone case), as well as any cloth will draw
out some of this oil due to "wicking"
action. This may give the microphone an uneven appearance
as the oils are drawn out of the microscopic surface layer.
To renew the appearance of the microphone simply "massage"
it gently with a lint free cloth treated with a small amount
of light machine oil or WD-40™ applied to the cloth
(not to the microphone!) will restore the microphone to "like
new" appearance. Be very careful whenever working around
the transducers to avoid contamination of the ribbon elements.
Age,
handling, and naturally occurring atmospheric conditions
will also cause physical changes in the appearance of the
finish due to oxidation. This patina is quite normal and
occurs slowly over time and is not considered an imperfection
in the plating process. If you have any questions regarding
the finish or care of this microphone please contact customer
service at Royer Labs (818) 847-0121.

| We
are all concerned about the negative affects of depleting
ozone in our upper atmosphere but have you considered the
effects of too much ozone right here on terra firma?
There is a recent
trend to use portable ozone generating machines in closed
spaces like homes and recording studios to get rid of unwanted
odors, such as smoke or mildew. Be aware that these devices
can cause irreparable harm to anything that contains natural
or synthetic rubber compounds. Microphones are extremely
vulnerable because capsules and shock mounts use rubber to
isolate components from vibration and low-frequency energy.
Ozone will destroy these items in a very short period of
time requiring a costly repair. Other devices are also at
risk. Tape recorders, CD changers, DAT recorders and video
recorders all use rubber components for shock absorption.
And don't forget your speakers and microphone cables. Anything
that has rubber, natural or synthetic, is at risk if you
use an ozone generating device. Check with the manufacturer
of these devices to see if they will guaranty that harmful
amounts of ozone are not being produced. We have included
a picture of an AT-84 shock mount that was ruined by an ozone
generating machine. The shock is less than three months old!

IMPORTANT
TECHNICAL BULLETIN REGARDING PS-101 POP SCREEN! |
Recently
we have become aware of PS-101 copycat pop screens being
distributed in the United States. They are being made in
China and they are dead ringers for Royer Labs' PS-101, which
is manufactured for Royer Labs by Stedman Corporation. Even
though these pop screens look like the real McCoy, they differ
greatly in performance. The patented expanded metal screen
used for the genuine pop screen works very effectively, while
the Chinese made copy does not! The Chinese version lacks
the angled louvers that are at the heart of the pop screen
and therefore acts more like a cloth pop filter than a pop
screen. These versions do not effectively prevent P-popping
and therefore we do not recommend their use. Please make
sure you purchase a genuine Royer Labs or Stedman Pop Screen.
The counterfeit versions are cheap, but they don't work well
and are no bargain at any price.
