This amplifier is the ideal solution for information points, cash desks and vehicles using a roof speaker system. The amplifier is equipped with a Bluetooth module, which prevents physical galvanic connection to sound sources and thus eliminates the possibility of hum and noise. The USB 5V power plug can be used as a charger for external devices. There is a main switch on the front panel, and there are also 2 microphone inputs with 6.35 mm TRS jacks, rotary volume controls for both microphones and an AUX input, and easy EQ tone correction settings. There is one stereo AUX input on the rear panel with RCA and 3.5 mm jacks.

The system is equipped with frequency synthesis technology, where frequency stability is ensured by a phase feedback loop (PLL) system in transmitters and receivers and allows automatic selection of up to 100 frequency presets in the UHF band for both channels. The RUD-802 system, which is easy to set up and control, works with constant acoustic quality over the transmission distance for the lifetime of 6 hours of batteries in the transmitters (2 1.5V, AA per microphone). It is the perfect system for a wide range of applications, singers, conference moderators, live events or AV presentations, where two microphones with manual control without interference can be used simultaneously. If a new transmitter needs to be assigned to the receiver, this is facilitated by the auto-scan feature to identify free frequency carriers. The system of synchronizing the receiver with any new transmitter is facilitated by automatic synchronization using infrared radiation without any manual adjustment. The receiver is equipped with an LCD screen showing the preset number, frequency value, transmitter battery life and the quality of RF and AF signals. If necessary, it is possible to replace (supplement) the handheld microphones with U-899P pocket transmitters with LM-60(4B) lapel microphones  or with HM-38(4B) headset microphones .

There is a main switch on the front panel and there are also 2 microphone inputs with TRS 6.35 mm jacks, rotary volume controls for both microphones and AUX input, and tone correction settings - bass and treble. There is one stereo AUX input on the rear panel with RCA and 3.5 mm jacks. The rear panel also has a DC connector o5.5 \/ o1.5mm for connecting the input supply voltage 12V to 15V \/ DC and terminals for connecting a load with an impedance of 4?.

Jeho malá velikost a nízká hmotnost usnadňuje integraci do malého prostoru. Zesilovač je třídy D, má proto velkou účinnost a malé zahřívání. Provoz na 12 až 15V DC se dokonale hodí pro přenosné použití nebo pro instalace, kde není k dispozici přímé napájení střídavým proudem. Tento zesilovač je ideálním řešením pro informační místa, pokladní pulty a vozidla využívající střešní reproduktorový systém. Zesilovač je vybaven modulem Bluetooth, který zabraňuje fyzickému galvanickému propojení se zdroji zvuku a tím odstraňuje možnost vzniku brumu a šumu. Napájecí zástrčka USB 5V je využitelná jako nabíječka pro externí zařízení. Na předním panelu je hlavní vypínač a dále  jsou k dispozici 2 mikrofonní vstupy se zdířkami TRS 6,35 mm, otočné ovládací prvky hlasitosti obou mikrofonů a vstupu AUX a nastavení tónových korekcí - basů a výšek. Na zadním panelu je jeden stereo vstup AUX s konektory RCA a Jack 3,5mm. Na zadním panelu je také DC konektor o5,5\/o1,5mm pro připojení vstupního napájecího napětí 12V až 15V\/DC a svorky pro připojení zátěže o impedanci 4?.
