Neumann were at the recent IBC show in Amsterdam to announce their first ever studio monitors, The KH120A and KH120D. The new loudspeakers take their first two initials from high-end speaker manufacturers Klein+Hummel, who have been part of the Sennheiser group (Neumann’s parent company) since 2005, and upon whose designs the KH120s are based.
The KH120A and KH120D are essentially the same monitor, with the only difference between them being that the ‘D’ version features digital inputs, in addition to balanced analogue XLR ins. Both are active designs, and are powered by two 80W Class-AB amps, one for the titanium fabric soft-dome tweeter, and one for the LF driver. The latter is 4.5 inches in diameter, while the former is one inch, and resides in what Neumann call a Mathematically Modelled Dispersion Waveguide, which has been computer designed to ensure optimal HF dispersion. Both drivers have their own analogue limiters and thermal protection circuitry.
The KH120’s ported cabinet is constructed from aluminium, and is said by Neumann to have minimal resonances and improved heat dissipation compared with other materials. The cabinet walls have been angled to reduce internal standing waves, and the ports use a patented system for reducing resonance.
Around the back, there are three four-way switches for adjusting the level of high, low-mid and low frequencies, as well as separate input gain and output level controls. The non-digital version, the KH120A, has one 10kΩ XLR input, while the digital version also allows you to use the XLR socket to input AES-EBU signals at sample rates of up to 192kHz (though this can also be achieved via a coaxial BNC connector).
One feature that is unique to the digital version is the ability to delay the signal, either to compensate for time-of-arrival differences caused by speaker placement, or to maintain sync when working with picture. Both the KH120A and KH120D are expected to be available towards the end of November, and will cost somewhere in the region of 650 Euros per speaker.
