The Perception wireless system comes complete with bandwidths up to 30 MHz and excessively low-current transmitters, which are unique in its class, cementing Perception Wireless as one of the most comprehensive systems in its price range.

The Perception Wireless is designed to accommodate musicians and entry-level audio technicians, although it has the capabilities to handle even the most difficult audio setups with up to 8 channels per band.

The pocket transmitter PT45 - which is the smallest in its class - runs on a single AA battery, and is compatible with all AKG MicroMics. The SR45 Stationary Receiver delivers a diversity system, professional XLR and 1/4 inch jack outputs and the SMPS solution.

• The ACT-818 is a 1/2U single channel rack-mountable receiver with metal chassis.
• A full-color VFD (vacuum fluorescent display) provides clear viewing of all parameters. All controls are intuitive and easily accessible, allowing for quick and easy system setup via a single rotary control.
• Enhanced RF circuitry improves anti-interference characteristics and system compatibility with a 64 MHz-wide bandwidth, allowing more interference-free channels to be selected.
• New digital diversity receiving technology eliminates signal dropout and enhances receiving range.
• Full-range sound quality is not affected by the strength of RF signals or operating distance.
• Digitally-processed RF circuitry and DigitnamicPlus™ technology eliminates compander noise, assuring a wireless sound quality that easily rivals cable transmission.
• Improved proprietary Audio A/D Converter provides a true dynamic range of 115 dBA, T.H.D.
• AES3id Digital Audio Interface facilitates a direct connection to digital mixing consoles and transmits signal without distortion, ensuring a stable S/N ratio which will not deteriorate in long distance transmission.
• Proprietary 256-bit encryption provides secure audio transmission, preventing unauthorized listening.
• 10 built-in SmartEQ™ presets and user-defined microphone capsule equalization allows faithful sound reproduction to suit artistsʼ preferences.
• 10 built-in digital anti-feedback SmartEQ™ presets minimize feedback effectively without sacrificing sound quality.
• Optional MIPRO RCS2.Net software allows real-time network remote-controlling and monitoring of 64 systems.

Set composed of:

• 1 x LDWIN42R
• 1 x LDWIN42BP
• 1 x LDWS100GC

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 734 MHz to 776 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.
