Reliable acoustic measurements require a microphone chain perfectly matched to the sound level meter, the field setup, and the specific acoustic field.
This versatile family of preamplifiers for HD2010UC, HD2010UC/A, and HD2110L sound level meters is designed to supporto free-field, diffuse-field, and outdoor configurations.
For HD2010UC and HD2010UC/A instruments, the HD2010PNE2 preamplifier provides CTC electrical calibration and a line driver for cables up to 10 m, supporting the pre-polarized UC52 microphone. The heated HD2010PNE2W variant features an integrated 5 m cable (10 m on request) for seamless integration with the HDWME outdoor microphone protection unit.
For the HD2110L, the HD2110PEL works with pre-polarized microphone capsules, while the HD2110PL supports 200V polarized models. Heated outdoor variants, HD2110PEWL and HD2110PWL, support HDWME installations with integrated extension cables extending up to 50 m.
HD2010PNE2 is a microphone preamplifier for UC52 microphones, featuring CTC electrical calibration and a line driver for cables up to 10 m. The preamplifier supports HD2010UC and HD2010UC/A sound level meters. The HD2010PNE2W variant adds a heated design and a 5 m integrated extension cable with a 10 m version available on request.
HD2110P is a microphone preamplifier for 1/2" microphones, compliant with the IEC 61094 standard and featuring CTC electrical calibration and a line driver for cables up to 50 m. Designed to support the HD2110L sound level meter, it is available in specific variants for both pre-polarized and 200 V polarized microphone capsules.
Built upon all the features of the standard version, the outdoor variant adds a heated design and an integrated 5 m extension cable, with lengths up to 50 m available on request. The preamplifier is available in the specific variants HD2110PEWL and HD2110PWL for pre-polarized and 200 V polarized microphone capsules, respectively.
The HD2110P preamplifier is compatible with MC21E and MC21P free-field capsules (pre-polarized and 200 V polarized, respectively). For diffuse-field measurements, it pairs with the MC22E and MC22P models, covering both polarization types.
