THE TELINGA INTEGRATED PARABOLIC MICROPHONE SYSTEM
The PRO 7 & PRO 7Wsystems - how to choose:
The Back-up
Handles:
PRO 7W - for Walkmans, analogue & digital
PRO 7 - for recorders with 48V Phantom power.
Microphones:
The Stereo DATmic - gives focused sound in mono and the
ambience in stereo.
The ”Classic” - an omni directional
microphone.
The "Twin Science" -
combines omnidirectional and cardioid capsules into one microphone.
The ”back-up” - a mono standard microphone for back up
purposes.
The
PRO 7 & PRO 7W handles power all Telinga interchangeable
microphones:
(shown with the Twin Science microphone)
Fit the Telinga PRO interchangeable microphone of
your choice to any of the following three bodies to match the requirements of
your recording system:-
· PRO 7W: For Walkman recorders, analogue and digital. Powered by an on-board re-chargeable 7,2v Ni-mHy accumulator.
· PRO 7: For equipment with 48V phantom power. Powered by the recorder.
The two types of handle have the following characteristics in common:-
· The active high-pass filter inside the handle cuts 12dB/octave with its 3dB knee point at 3000Hz. (Traffic filter)
· A transformerless output amplifier keeps the output impedance at only 200 ohms (100 ohms in the PRO 5 W)
· Radio disturbances are attenuated by an RF trap.
·
The Parabolic Dish is vacuum moulded out of
1.2mm unbreakable transparent Poly-carbonate.
It is flexible and can be rolled into a cigar shape with a diameter of about
150 mm (6 ins).
· Diameter of parabola: 580mm
· Total Weight with microphone 870 - 920 grams.
· Output connections:
· PRO 7Ws: one 3.5 mm stereo mini-jack..
· Pro 7: two Neutric 3-pin gold plated XLRs
THE MONO
MICROPHONES
There are basically two types of capsules (electrically powered sound
receptors) utilised in Telingas and the
advantages and disadvantages need to be understood.
Omni-directional
Advantages: Very
low wind and handling noise
Disadvantages: Sometimes
too much ambience recorded.
Cardioid
Advantages: Maximum attenuation of
ambience with far less wind and handling noise, ideal for recording birdsong, movement
effects of footsteps, grass, etc.
Disadvantages: Like all directional
microphones, they are sensitive to wind and handling noise so a Rycote Windshield
should be used to cover the dish opening to protect the cardioid capsule from
wind buffeting, and a tripod is usually a must.
The Telinga “Classic" microphone:
The Classic uses a conventional design for parabolic systems with omni-directional
microphone capsules collecting the focused sounds from the dish as well as the
overall ambient sounds.
The Telinga “Twin Science" microphone:
The Twin Science combines cardioid
and an omni-directional capsules into
one microphone with each capsule individually output to L & R channels. The best channel recording can then
be selected at replay. The two recordings can be mixed without audible phase
problems.
Because the cardioid microphone faces towards the dish, it optimizes the reflected
sound of the distant subject and suppresses the background, thereby improving
the directivity, by concentrating on the sound reflected by the dish. The
parabolic dish effectively "narrows" the zone of sound collected
and the increased directivity of the cardioid excludes much of the surrounding
sound.
Inherent Noise
Level of only 14dBA
Advantages: Both
microphone capsules can be recorded simultaneously creating a backup from the
omni in case of sudden wind or handling
noise but retaining the benefits of a
higher signal from the cardioid when conditions permit.
Disadvantages: None.
THE STERO
MICROPHONE
The Stereo DATmic
–
High performance, low noise microphone
for
digital
recording.
The Stereo DATmic has an Inherent Noise Level of only 12 dBA. Thus, it does great justice to the dynamic range of solid state flash memory field recorders such as the Fostex FR-2LE as well as the older DAT's and Mini Disc recorders.
The frequency range of the Stereo DAT microphone is 60 - 18.000 kHz without base filter.
The impedance from the handles:-
100 Ohms non-symmetrical out from the PRO 7W handle
200 ohms, balanced, from the PRO 7 handle.
Handling and wind noise suppression is
excellent.
The over-all sound characteristics of the DATmic,
is a "soft" high and a "big" and amazingly
transparent mid and low. Without the
parabola, it is a good multi-purpose stereo microphone
for capturing distant low-signals.
The connecting cablefrom handle to recorder is slightly less than 1 meter.
Because of the low output impedance you can have very long extension cable
to it, up to 40-50 meters
