Model
2210
Battery
powered microphone signal conditioning for multi-channel DAT
recorders, analog tape recorders and computer-based data
acquisition systems. Provides microphone polarization
voltage, adjustable gain and filtering (A-weight, C-weight,
or band-pass). Can also be used with ICP and charge-coupled
accelerometers with the appropriate accessories.
Automated
sequential multi-channel sound and vibration measurements
using a single or dual channel analyzer under PC control via
RS232 interface. One example is the measurement of sound
power using multiple microphones in anechoic, hemi-anechoic,
or reverberation rooms as per the ANSI S12.30 series or the
ISO 3740 series of standards. Another is the measurement of
reverberation time, airborne sound transmission loss and
impact isolation using multiple microphones.
