2699 -
CCLD, A-weighted microphone preamplifier
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.
Uses
- Sound measurement with optimum channel cost
- Sound measurements using ½", prepolarized microphones
- In-car measurements to ANSI S 1.4, IEC 60651 and IEC 61672 standards
Features
- Connects directly to CCLD 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
The preamplifiers low output impedance allows the problem-free use of long extension cables. Its robust, compact design means that you can use Type 2699 in a wide range of environmental conditions.
