ISE 2019: Adam Hall Group expands LD Systems installation portfolio

New additions include new IPA and IMA installation amplifiers and the newest addition to the award-winning MAUI series, the MAUI I1 column speaker

The Adam Hall Group will be presenting a range of audio solutions for professional use in AV fixed installations at ISE 2019, stand 7-W200. 

This will include LD Systems’ new IPA and IMA installation amplifiers and the newest addition to the award-winning MAUI series, the MAUI I1 column speaker.

With the IPA series, LD Systems has expanded its installation portfolio with DSP-based 4-channel installation power amplifiers. The new IPA412 (120W) and IPA424 (240W) feature integrated transformers per channel and provide 100V/70V tap and low-Z output down to 4 ohms. Each model includes a slot for an expansion card, which can be used to control the IPA amplifiers, including all DSP parameters, via Ethernet, and to integrate them into larger installation networks thanks to Dante AoIP connectivity. In the basic version, the IPA amplifiers work as a standard installation amplifier with 100/70V tap and independent low-Z output for excellent sound quality. The DSP section includes PEQ (with matched speaker library), dynamics, matrix mixer, priority source selector and delay. Via a CAN bus (Controller Area Network), the IPA series is also capable of interacting with remote units and paging microphones.

The IMA30 is the first member of LD Systems’ new IMA series of installation mixing amplifiers for use in fixed installations. With its versatile input and output options and multi-stage priority switching, the IMA30 enables flexible integration in commercial and industrial applications. On a compact 9.5″ chassis and 2RU, the IMA30 offers two mic/line inputs with +24VDC phantom selector, two stereo line inputs plus an integrated Bluetooth wireless signal input for connecting music sources, and a priority input for emergency paging. Outputs include a powered 30W @ 4 Ohms output plus a 70/100V tap as well as bass and treble tone controls. A Low-Z/High-Z selector separates the output signal from the output transformer, in order to get the best frequency response for low impedance applications. The IMA30 can also be used in conjunction with external amplifiers, subwoofers or music-on-hold systems via the separate aux line output. The music mix selector can be used to determine whether the entire mix or only the selected music source is channeled to the output.

LD Systems will also present a new series of installation loudspeakers for outdoor and indoor use. The 2-way systems come in the new dynamic LD Systems design and are available as low-impedance version (8 Ohm) and high-impedance version (16 Ohm) with tap switch for variable power output in 70/100V applications. The sizes available are 3”, 5.25” and 8”. For flexible integration into different environments, the speakers feature an integrated wall mount plus a convenient slide-and-lock mechanism. Furthermore, the 27° tilt and 45° pan mechanism allows exact positioning for precise sound coverage.

The MAUI I1 is the next step for the award-winning MAUI series of active column speaker systems from LD Systems. The MAUI I1 is a surface-mount column speaker with 9 x 3” full-range woofers and 2 x 1” neodymium high frequency drivers with integrated 2.5-way crossover and 120W RMS power at 8 Ohms. The BEM-optimised high-frequency waveguide, which enables precise adjustment of the vertical dispersion, ensures homogeneous dispersion in acoustically challenging environments. For seamless integration into constant-voltage loudspeaker systems, the MAUI I1 has an input mode switch with 8 Ohms/70/100V options and a power tap selector for high impedance use with 60 – 30 – 15 – 7.5W taps. A dedicated U-bracket for flexible wall/ceiling mounting is included.
