Building and architectural acoustics measurements often need high, controllable excitation without adding unnecessary noise to the test environment. HD2050.20 drives the HD2050 dodecahedron or HD2050.30 facade loudspeaker with 1200 W @ 12 ohm and 2 x 530 W RMS continuous power, giving acoustic teams the output needed for demanding sound insulation and room acoustics work.
The integrated white/pink noise generator reduces external equipment needs, while the auxiliary input allows external generator signals such as sine sweeps. A wireless remote control can operate the internal generator up to 100 m away, supporting practical source control during field measurements.
For site-specific response tuning, the internal DSP works with PodWare software via USB. Users can manage mute, gain, parametric EQ, shelving filters, HP and LP filters and delay, then load user setups into the amplifier memory. Factory presets for HD2050 and HD2050.30 help match the amplifier to the connected source.
The system includes the HD2050 dodecahedron, HD2050.20 digital amplifier/noise generator and related accessories. It can also operate with the HD2050.30 facade loudspeaker or the HD2050.40 subwoofer.
The HD2050.20 includes an internal white and pink noise generator with manual level control. An auxiliary input allows operation with an external generator for signals such as sine sweeps.
The amplifier provides selectable presets for the HD2050 dodecahedron and HD2050.30 facade loudspeaker. A separate User DSP function loads a correction curve created in Podware software.
The integrated HD2050.20R remote control kit operates the internal noise generator from up to 100 m. The system uses a portable transmitter and an integrated receiver with external antenna.
The HD2050.1 stand is retractable and extendible from 1300 mm to 2050 mm and includes wheels. The HD2050.30.2 support positions the facade loudspeaker at 45° on the ground or on the stand.
Source connections use Neutrik speakON connectors. The amplifier includes Neutrik XLR output, Combo input, NL4FC speakON output, powerCON AC power connection and USB for PC-based DSP management.
