PL+S 2019: Adam Hall Group premieres audio innovations

The new products include many from LD Systems, as well as the Gravity Touring Series and Palmer Monicon Series

At this year’s Prolight + Sound (April 2–5, 2019) in Frankfurt, Germany, the Adam Hall Group will present a number of new pro audio product innovations.

LD Systems – Free Your Sound

At Prolight + Sound, LD Systems will reveal the brand’s new positioning and demonstrate how this comprehensive approach has accompanied and defined the latest from the Adam Hall Group’s pro audio brand from the onset: from the U500 IEM Series’ in-ear monitoring systems, the MAUI i1 fixed installation solution, the compact IMA and IPA installation amplifiers, to the flexible and rugged DQOR outdoor speakers.

LD Systems U500 IEM

LD Systems will present its U500 IEM Series of in-ear monitoring systems, designed for bands, musicians, and hire companies. Available as a set with or without headphones, the U500 IEM Series offers a switchable transmitting power of 2 mW, 10 mW and 30 mW, an incredibly clear OLED display, three-band EQ with parametric mids, username entry and storage for ten presets. Depending on the frequency band, it also allows for the operation of up to 12 parallel systems. The U500 IEM Series is available in five versions for worldwide use in different frequency ranges.

LD Systems MAUI i1 for fixed installations

The MAUI i1 sees LD Systems take the next step and also allow planners, integrators and end users to use the brand’s active column speakers as part of fixed installations. The MAUI i1 features nine three-inch full-range neodymium woofers and two one-inch high-frequency drivers, including two-way crossover, to deliver 120 W (RMS) at eight ohms. The BEM-optimised high-frequency waveguides provide precise control of vertical dispersion in order to ensure consistent sound distribution, even in acoustically difficult environments. For seamless integration into speaker systems with constant voltage, the MAUI i1 also has an eight ohm/70 V/100 V switch with taps for 60, 30, 15 and 7.5 watts. A special U-shaped bracket for flexible wall mounting is also supplied.

LD Systems IPA & IMA Installation Amplifiers

With the IPA and IMA series, LD Systems expands its growing installation portfolio to include mixing amplifiers specifically for fixed installations. The IPA series includes DSP-based, four-channel power amplifiers – IPA412 (120 W) and IPA424 (240 W) – with built-in transformers per channel, 100 V/70 V-taps and a low-Z output (four ohms). The IPA-models can be equipped with an expansion card to control all parameters via Ethernet and to integrate the amplifier into larger installation networks via Dante AoIP-connectivity. The IPA series can also communicate with remote devices and paging microphones via a CAN bus (controller area network).

With the IMA30, LD systems presents the first component of the new IMA series. Thanks to a wide range of input and output options, including Bluetooth for the wireless connection of music sources, as well as multilevel priority switching, the mixing amplifier in compact 9.5-inch housing can be flexibly integrated into commercial and industrial applications. The IMA30 provides four priority levels for emergency calls, microphone/line inputs and music sources, as well as selectable automatic standby mode for Energy Star certification.

LD Systems DQOR Outdoor Speakers

The new DQOR-series installation speakers are suitable for both indoor and outdoor projects. The two-way systems in the updated, dynamic LD Systems design are available in three”, 5.25” and eight” editions and are available in low and high-impedance versions at eight or 16 ohms. Furthermore, the DQOR models have a selector switch for selectable power tapping in 70/100 V environments. For flexible use in a wide variety of indoor and outdoor applications, the housing features an integrated wall-mounting bracket and a practical slide/lock mechanism. Thanks to the recessed front panel with no visible cable routes, the DQOR series is also suitable for integration into sophisticated interior design environments. For precision sound dispersion, such as in gastronomy and retail sectors, the speakers have a built-in 27° and 45° tilt-and-pan mechanism. The new DQOR series is available in black and white.


The Monicon XL is the flagship of the Palmer Monicon series and embodies the new Palmer positioning, which now characterises the overall new design and appearance of the brand. Equipped with many professional features, the Palmer Monicon XL is ideal for mixing in home and modern studio environments. The console design’s clearly structured user interface is divided into two levels and facilitates flexible table positioning and user comfort. A feature unique to the Monicon XL is the correlation meter, which displays the phase difference between the left and right stereo channels to enable error recognition in a mix’s mono compatibility. Furthermore, the fully analogue audio circuitry ensures no latency when listening. Another benefit for users who want to make their L/R studio monitoring even more flexible is the additional sub out on the rear of the housing.

Gravity Touring Series

With the new Touring Series, Gravity presents the first ever range of stands specifically developed for the professional rental market. The robust all-metal stands feature rugged construction and combine stability and functionality with innovative details. These details include captive, unlosable metal adjustment knobs and a single-twist boom securing system. The new Gravity Touring Series is expected to be available during the third quarter of 2019. The series will launch with a microphone stand, a speaker stand and a lighting stand. In addition, the Touring Series is fully compatible with other Gravity products.
