Sonodore PG-78
Acoustic Grid for RCM-402 and CCM-65 for amplitude lift at 15kHz

Experience learns that if omnidirectional microphones are placed relatively far from the
musical instruments that you want to record, the result sounds somewhat dull. This also
applies to the Sonodore RCM-402. To solve this problem, Rens Heijnis developed a
grid that boost the higher frequencies more than the lower ones; it can be considered
as an acoustic
equalizer.

The standard grid of the Sonodore RCM-402 provides an almost flat frequency
characteristic.The PG-78 grid, on the other hand (made of titanium) shows a rise of the
high frequencies with a peak at approximately 15 kHz and a gain of 3.5 dB
(please refer to the graph below).
These values should be added to the frequency characteristic of the Sonodore RCM-402 .
The increase of the high frequencies does not introduce any additional noise, which
means that the signal-to-noise ratio even improves slightly when the PG-78 grid is being
used.

The directional characteristic is slightly influenced by the PG-78:
from 5 to 10KHz the directional characteristic is a little better than with the standard
grid (0.1-0.3dB); at 20kHz, the directional characteristic is slightly worse
(depending on the angle: 0.1-1.5dB).

Sonodore PG-88
Acoustic Grid for RCM-402 and CCM-65 for Amplitude lift at 20kHz

The PG-88 grid, (made of titanium) shows a rise of the high frequencies with a peak at
approximately 20 kHz and a gain of 2.5 dB (please refer to the graph below).
These values should be added to the frequency characteristic of the Sonodore RCM-402.

Together with the standard grid and the  PG-78 there is now a wide range of possibilities
for acoustic equalizing the Sonodore microphones. The PG-88 delivers a virtually ideal
frequency response with a slight boost of 2,5dB at 20kHz gradually coming down
to 0,7dB at 30kHz which is often perceived as delivering a more 'open' sound stage.
For use at greater distances then 1 meter this proves to be a very nice feature indeed.
Many mastering engineers add this bit of 'top-end' in recordings.
The Sonodore can add this now right at the source. All other qualities of the RCM-402
stay in tact, like the exceptional impulse response and omni directional character
of the microphone.

Sonodore Suspensions
The suspensions, mechanically isolates the microphone from the pole,
thus preventing unwanted cross talk from the floor and the microphone stand.
Together with the other Sonodore accessories, these clamps are a very practical
and worthwhile addition to the Sonodore product range.
Suspension for Sonodore RCM-402 and LDM-54:
Rycote InVision 7HG
Suspension for Sonodore MPM-81 and MPM-91:
Rycote USM
 

           

 

 

Sonodore Windscreen
For making outdoor recordings with the RCM-402, there are 2 types of windscreens available:
WS-4 diameter 4,5cm
WS-7 diameter 7cm. It will reduce the wind noise by about 25dB
