Microphone Stand Mount -- Fixed and Shock
TetraMic is supplied with a shock-mounted microphone clip. The clip
mounts to any standard 5/8-27 threaded microphone stand or fixture. A
fixed stand mount (non-shock mounted) is also available.
Phantom Power Adapter (PPA) and Breakout Cable
Phantom Power Adapters (PPA) are available to power TetraMic from
microphone pre-amplifiers and mixing boards that supply standard 48 Volt
phantom power. Four PPAs are required along with a breakout cable. The
breakout cable plugs into TetraMic's 6-pin output jack (or into an
extension cable) and provides four 3-pin mini-XLR-F plugs, each of which
plugs into a PPA. The PPA also has an standard XLR-F jack from which a
balanced microphone output signal is available and through which 48 Volt
phantom power is supplied.
6-Pin Extension Cables
6-pin-F to 6-pin-M extension cables are available in lengths of 6-,
10- and 20-feet. These cables typically are used between TetraMic and
either a PPA breakout cable or a 4Mic breakout
cable.
Since the TetraMic's output is unbalanced, to reduce the pickup of
electromagnetic noise and hum, we recommend using only as long a 6-pin
cable as is necessary. If you need to run long cables, we recommend
using the PPA to convert TetraMic's output to balanced, and then
preferably using a four-channel snake, or less preferably, four
individual balanced XLR cables.
Wind Screens
Wind screens are available to reduce wind noise when recording outdoors
with TetraMic.
The two-part foam wind screen fits over and under TetraMic's capsule
head. It should be used in light to medium
wind conditions.
The windscreen with a combination furry outer layer and
foam inner layer should be used in heavier wind conditions. (The
furry/foam wind screen includes the foam wind screen -- there's no
need to order both.)
An even more effective (and considerably more expensive) windscreen
system is available from Rycote dealers. You would order the Small
(1-Modular) Stereo Modular Suspension with 12mm sleeves to fit the 19mm
suspension holders, the Stereo Windjammer 1 and the WS1 (Stereo Blimp
windscreen).
Windscreen Usage: Push the bottom foam collar up onto the
TetraMic shaft as far up as it will go, seated against the bottom of the
two lower capsules. Fit the top foam over the top of the TetraMic and
push it down as far as it will go. Then fit the furry sleeve over
it.
Four-Channel Snake
For long TetraMic cable runs we prefer to use an ETS InstaSnake PA200 snake. InstaSnake
uses a single, lightweight and low-cost CAT5, CAT5e or CAT6 shielded
twisted pair cable, as used in data networks. Using an InstaSnake you
can run TetraMic's four signals for as far as 850 feet without
appreciable signal degradation. Separation between channels using the
InstaSnake is greater than 100 dB. And since you only need to lay one
slender shielded CAT5-type cable, there's no tangle of multiple
microphone cables or large old-style snake cables.
Cables for the RED Digital Cinema Camera
TetraMic works great with the RED Digital Cinema Camera. Its
microphone pre-amp inputs are four mini-XLR jacks. We offer 6-foot
cables that plug into the TetraMic PPA (XLR-F) on one end, and the RED
camera mic inputs (mini-XLR-M) on the other. If you need other lengths
please contact us.
