Fully programmable Digital Signal Processor with USB connectivity.

With its flexible potential applications, the PDI-05 is equally at home in the studio and home recording as well as onstage, e.g., in the racks of Rush or Def Leppard. Originally developed for the preamp/multieffect/power amp combination popular in the late eighties and nineties, this authentic reissue is also suitable for heads and combo amps. What's more - the precise frequency correction of the stereo speaker simulator turns overdrive and distortion pedals or multieffect units into a genuine preamp with an authentic sound. The PDI 05 lends digital keyboards and drum machines fullness and analogue warmth without complex and time-consuming post-processing at the mixing desk. A built-in headphone amplifier permits "environmentally-friendly" practicing

Engineered for rock-solid reliability day in, day out this active subwoofer is a truly professional performer. With built-in presets for quick system integration and a variety of cardioid array configurations it is completely user-friendly. The Stinger® SUB 15 A G3 is powered by high efficiency Class D amplification with a mighty 450 watts RMS output. It drives a custom designed 15” woofer delivering a huge bottom end with terrific punch and excellent definition.

The Stinger® SUB 15 A G3 incorporates LD Systems’ proprietary DynX® DSP technology to ensure top-level performance and pristine, distortion-free bass reproduction at all times. Designed to be a real workhorse throughout, the well-braced bass reflex enclosure is constructed for horizontal and vertical orientation. It is made of rigid 18 mm birch ply and coated with ultra tough polyurea for extraordinary strength and durability. Sporting a steel front grille, M20 threaded pole insert, stacking recesses and ergonomic handles the Stinger® 15 A G3 is an attractively priced choice for truly professional sound reinforcement.

The U500® Series vocal sets were developed in Germany to bring you affordable professional technology and sound quality. The radio systems for vocals and speech deliver impressive performance and high reliability, which will certainly exceed your expectations. We have designed the range specifically for professional users to ensure that your performance is an impressive and emotional experience.

Selectable transmit power up to 30 mW provides the U500® vocal sets with a free-field range of over 100 metres. They are available in three frequency bands: 584 - 608 MHz and 655 - 679 MHz, where 12 systems can be operated simultaneously, and 823 - 832 MHz + 863 - 865 MHz, where six systems can be operated at the same time. The True Diversity UHF wireless systems are equipped with an automatic scan facility to find the best free frequency, and convenient one-touch infrared synchronisation of transmitter and receiver to facilitate easy set up.

High-contrast OLED displays provide an excellent overview of functions, with indicators for group, channel, radio frequency, and signal strength and battery status. You can even enter individual usernames. In addition to the squelch function, the transmitter’s silent pilot tone ensures fail-safe operation. It protects against interference and mutes the receiver if signals without this tone are present. The U500®’s efficient technology and high-quality components provide clear, distortion-free transmission without latency or artefacts. Low power consumption means that the transmitter can run for up to 10 hours with 2 x AA batteries.

The U500® Series vocal sets are available with hand-held transmitters, headsets, lavalier microphones and single or double receivers. The hand-held transmitters feature interchangeable microphone capsules to suit singing or speaking.

Overview of frequency ranges of vocal sets:

• U505 // 584 - 608 MHz // 12 systems can be used simultaneously
• U506 // 655 - 679 MHz // 12 systems can be used simultaneously
• U508 // 823 - 832 MHz + 863 - 865 MHz // six systems can be used simultaneously
• U506 UK (Channel 38) // 606 – 614 MHz // six systems can be used simultaneously
• U518 // 1785 – 1800 MHz // four systems can be used simultaneousl

Perfectly equipped throughout, the MAUI® 5 GO is the ultimate system to deliver crystal-clear, powerful sound in any location. The ultra-portable battery-powered column-PA is supplied by a high-performance lithium-ion unit that provides power for up to 20 hours operating time. The charger is built into the subwoofer. An external charging dock is available as an accessory. Inputs for microphone, instrument and line signals as well as Bluetooth® stereo streaming make the MAUI® 5 GO the ideal system for street musicians or for music and speech reproduction at private and business events and all mains power-free applications.

Its superlight weight of just 13 kg makes the four-piece design ultra-easy to transport, and thanks to its special multipin connectors, it is assembled and ready to use in seconds. The line-array arrangement of the drivers achieves an extremely high range. The system’s wide dispersion and excellent feedback-resistance removes the need for separate monitors. With 800 watts peak power, the MAUI® 5 GO is the loudest and best-sounding battery-powered PA system on the market, effortlessly providing sound for audiences of over 100 people.

For unparalleled sound quality in all applications, the column system features LD Systems' LECC DSP with multi-band limiter, equalizer, compressor and crossover. The integrated 4-channel mixer provides separate volume controls for the input channels, sum and subwoofer as well as a variable high-frequency boost to facilitate fast and balanced adjustment to the sound. LD Systems’ Quick-Swap Technology® also facilitates immediate and simple battery replacement for practically unrestricted operating times for the MAUI® 5 GO.

Due to the changed situation in the area of general frequency allocations for the operation of wireless systems starting in 2015, LD Systems decided to develop the even more flexible and highly professional WIN 42 wireless system.

With its outstanding audio quality, the LD Systems WIN 42 UHF system offers numerous potential applications for live performances and permanent installations. The working UHF frequency range is 516 MHz to 558 MHz. Both the handheld microphone and belt pack transmitter versions provide any vocalist, speaker or instrumentalist optimal transmission of his or her performance with the greatest possible freedom of movement. By means of a threaded connection, the microphone head of the handheld transmitter can be swapped quickly and easily (dynamic and condenser capsules).

The system has more than 1680 freely selectable frequencies and thus makes it possible to operate up to 20 systems simultaneously. The "channel scan" function assists you in finding and tuning to a transmission frequency without interference. This frequency is then transmitted simply and conveniently from receiver to transmitter via an infrared link. The transmitting power is adjustable in 3 stages (10, 30, 50 mW) directly on the microphone, permitting adaptation to any environment.

The half-rack True Diversity receiver houses numerous system features, for example, a transmitter battery status indicator on the receiver display, an indicator for the (transmitter) "Mute On/Off" function on the receiver display, 4 EQ presets that are switchable at the receiver, and much more. A highly professional system embodying the outstanding value-for-money that is so typical for LD Systems.
