The SV 01A is Type 1
microphone preamplifier. It accepts standard 1/2" condenser
microphones with 0 V or 200V polarisation voltage. It has 7-pin LEMO
connector. |
The SV 02 is 1/2"
condenser microphone. With 50 mV/Pa sensitivity, 200 V polarisation
voltage and 2 Hz - 20 000 Hz flat characteristics (typical) it
fulfils all requirements for precision sound measurements.
The SV 22 is robust, low cost
1/2" condenser microphone intended for measurements in heavy
environmental conditions. It has 200 V polarisation voltage and 10
Hz - 16 000 Hz flat chracteristics (typical). 25 mV/Pa sensitivity
ensures measurements of high level industrial noise.

SV
16 16 Channel Multiplexer
 |
The SV 16 is 16 channel,
condenser microphone preamplifier or ICP' compatible accelerometer
multiplexer intended for sound and vibration measuring systems. |
The
multiplexer can be configured as 16 to 1 or double 9 to 1. Each 8
inputs can be independently configured as microphone preamplifier or
ICP' compatible accelerometer. The SV 16 multiplexer can be
controlled manually or remotely via RS 232 or IEC 625 (IEEE 488)
built in interfaces.
