Preamplifier Type 2699

TYPE 2699

CCLD, A-WEIGHTED MICROPHONE PREAMPLIFIER

Designed to eliminate low-frequency disturbance caused by body boom and road noise during in-car measurements

Code Polarization Freq. range (low) Freq. range (high) Diameter Lower operating temperature Higher operating temperature Lower operating temperature Higher operating temperature Connector Calibration facility
-2699--- CCLD 10 Hz 20 kHz 1/2 inch -20 °C 60 °C -4 °F 140 °F BNC None

Type 2699 uses a built-in, A-weighting filter to eliminate low-frequency disturbance caused by body boom and road noise which would otherwise be a source of error during in-car measurements. Its robust, compact design means that you can use Type 2699 in a wide range of environmental conditions.

  • Connects directly to DeltaTron input
  • Current output allows use of long, inexpensive, coaxial cables
  • Built-in, A-weighting filter for in-car noise-signal reduction
  • Dual-polarity overload-detection facility
  • Low noise and high dynamic range
  • CE and Australian C-tick compliance
