The HD2050.20 amplifier incorporates a white / pink noise generator and an auxiliary input to receive signals from other external devices.

Using supplied Podware software you can modify the EQ curve stored in the amplifier’s DSP in order to tailor the frequency response of the system to specific measurement needs.

It’s also possible to connect the HD2050.30 façade loudspeaker or the HD2050.40 sub-woofer (matched to the source HD2050) to HD2050.20 amplifier.

The system can be both AC and DC current supplied.

It allows calibrating 1/2” (1/4” with HD2020AD4 adapter) microphones with mechanical dimensions compliant with IEC 61094-1 and IEC 61094-4.

The generated sound pressure level is equal to 94 dB at 1000 Hz frequency. A LED signals the low battery condition.

Advantages of the HD2024 calibrator:

• The 1000 Hz frequency allows calibrating sound level meters with any frequency weighting (LIN, A, B, …), without applying any correction factor.
• The generated sound pressure level is indipendent of atmospheric pressure: you don’t need to adjust the value according to static pressure over a wide range of values.
• Its simplicity of use allows even unskilled staff to use it.

It includes ISO17025 Calibration Certificate.

Features:

• High performance materials Sound Insulation: a 130 dB SPL in the frequency range 45 Hz to 120 Hz allows the subwoofer HD2050.40, combined with HD2050 dodecahedron and HD2050.20 digital power amplifier, to excite rooms in order to measure extremely high insulations at lower frequencies. HD2050.40 is the correct solution for laboratories with measurement requirements up to date with the development of highperformance insulating materials in construction and shipbuilding fields
• Large rooms architectural acoustics: HD2050.40 subwoofer integrates HD2050 dodecahedron in applications where reverberation time measurement of high-volume environments is needed. In such environments, often the sound power and frequency extension characteristics of dodecahedron loudspeaker, are not sufficiente to recreate a good diffuse sound field or even high sound pressure levels on the walls of large rooms. The measures in these sound field conditions can be unreliable, or heavily dependent on the need for a very low background noise. In these cases, HD2050.40 is the correct solution.

The system is composed of dodecahedron loudspeaker HD2050, digital power amplifier HD2050.20 and related accessories; it allows to perform building and architectural acoustics measurements:

• Acoustic insulation
• Buildings acoustics
• Acoustic absorption
• Reverberation time
• Room acoustics ( RASTI, STI, Clarity, Definition descriptors etc.)
• Pulse response

HD2050 is a sound source able to emit sound energy in the room in a isotropic way with very high very high sound power levels. The HD2050 sound source is designed to offer maximum performances with special attention to international standards in the field of architectural and building acoustics.

The standards it complies with, are EN ISO 140-3:2006 and EN ISO 3382:2001 as concerns directivity.

HD2050 features a wide extension frequency response and provides an emission sound power level of more than 122dB re 1pW. Twelve coaxial loudspeakers arranged on the dodecahedron faces, provide a high acoustic performance. The twelve faces cabinet is multilayer wood made and has a light weight allowing an optimal on site portability. The double components plastic coating VFI-2513 gives the case a high hardness, so to conform ASTM (American Society for Testing Materials) standards. A further opaque geal-coat finish makes the cabinet surface scratch and waterproof resistant.
