Qoms1
Monopole Omnidirectional hemisphere sound source
Qoms1 is a unique small and lightweight hemisphere monopole pointsource for broadband sound measurements.
Like it’s fully omni-directional Qoms2, the Qoms1 sound source can be used for acoustic optimization of performance sites such as theaters, schools or religious sites for speech and music.
A smooth broadband spectrum from 50 – 16000 Hz and output level of Lw 109 dB allow measurements in large spaces.
he measurement can be conducted very fast and accurately at high broadband output levels (122 dB Lw). Another advantage of using Qohm is that no subwoofers are needed and it offers the highest quality in material within the smallest dimensions and extremely lightweight. This means that the product can easily be taken on-site by only one single consultant.

The Qam power amplifier provides an extremely high power/weight ratio for maximum portability. The internal firmware and DSP allow a very flexible use with different sound sources. The button-controlled operation is fast, straightforward, and stable. Application dependent, internally generated white/pink noise, sine sweep and pulsating noise signals are available as well as acceptance of any external signal generator. Especially for measurement in difficult small spaces, a low frequency third octave band equalizer allows adaption to the measurement space. Remote activation and de-activation up to 100m. range in free sight. Equalization is available for the Infra-Qsources sound sources and up to 10 settings per type of sound source can be stored for standardized measurements
