an excellent impulse response, reproducing all
transient phenomena in music and speech
without coloration. The entire internal con-
struction is decoupled from the housing to
avoid structure borne and handling noise.
Electrical features
The output signals of the included matrix am-
plifier are in either MS or XY format. The small
capsules are mounted in close proximity to en-
sure transparent and coloration-free stereo
sound with excellent mono-compatibility. The
stereo acceptance angle is variable and con-
trolled remotely.
Filter and attenuation
For the handling of very high
sound pressure levels, a 10 dB
attenuation can be switched
ON to avoid overloading of the
following equipment.
To suppress structure borne
noise, a high-pass filter in the
matrix box provides cutoff fre-
quencies of 40 Hz, 80 Hz, and
200 Hz.
Battery supply
The RSM 191 system is fed
from either 2 x P48 phantom
power or from a 9 V battery in-
side the matrix box.
One alkaline battery provides
8 hours of operation.
