mixer / preamplifier with 12 inputs and 4 outputs. It offers 4 mic/line inputs with selectable priority: the four microphone inputs override all other inputs, and mic‑input 1 has priority over mic inputs 2‑4. Each mic input includes volume control and a “voice” control, and phantom power (24 V) is available. There are also 4 stereo line inputs on double RCA connectors, selectable via a dedicated knob, plus master volume and tone controls. The outputs include two XLRs for left and right channels (each with independent volume control), one stereo output, and one stereo recording output. The unit fits in a 1U rackmount enclosure.

audio transmission and reception via Ethernet, supporting daisy-chain or star connections and allowing for a redundant network configuration. It can connect up to 16 M-8080D matrix mixer systems, providing up to 192 inputs and outputs. This makes it ideal for systems with numerous zones or floors, such as in large building complexes, and it can utilize existing Ethernet infrastructure.

unidirectional cardioid dynamic microphone is designed for both handheld and stand‑mounted use. It features an ON‑OFF switch for convenient muting, and a male XLR connector for professional audio connection. The body is finished in anthracite grey and is fitted with a black mesh grille plus an antipop filter to reduce plosives. With high performance and high‑quality voice reproduction, it delivers low distortion and is built to resist knocks. The special capsule suspension mount helps isolate handling noise, making the microphone ideally suited for speech‑applications.

unit offers balanced line input and output via XLR‑F and XLR‑M sockets with adjustable sensitivity, alongside an unbalanced line input via double RCA connectors. It also provides a dedicated RJ45 socket for connection of a MBT 1101‑series microphone station, and a telephone/emergency audio input with adjustable threshold and sensitivity for priority calls. On the front panel, there is a master volume control along with bass and treble tone controls, while a rear‑panel selector switch enables or disables the front panel’s tone and volume controls. The loudspeaker line output supports constant‑voltage operation (50 V / 70 V / 100 V) or 8 Ω impedance connection. An LED‑type VU‑meter on the front gives immediate visual feedback of output power. Also included are contact inputs for activating input precedence (override) and a built‑in alerting chime with level control. The unit supports selectable power supply modes at 230 V AC / 115 V AC and 24 V DC mains.

a UHF receiver with 193 selectable channels and PLL-synthesized technology. It features pilot tone and noise squelch for clear signal reception, as well as true diversity for stable and reliable operation. The unit can be used as a tabletop device or mounted in a 19-inch rack.

The 60W/120W amplifiers feature a comprehensive range of inputs and controls, including one XLR microphone input with phantom power and support for MBT 1101 series desk microphones (RJ45, CAT5 SFTP cable), as well as one MIC/LINE input with phantom power and a selectable MIC or LINE mode. They offer two XLR balanced microphone inputs with phantom power, including MIC1 equipped with A.P.T. (Automatic Priority Threshold) adjustment, and two AUX inputs for sound sources such as tape or CD. Micro-switches allow for setting priorities and input functions, supporting up to eight desk microphones with cascade connection. There is a TEL/EMERG input for emergency calls featuring input level and activation threshold (A.P.T.) adjustment. The amplifier provides a line auxiliary output and loudspeaker line outputs with constant voltage options of 50-70-100 V or low impedance 8 Ohm. Additional features include terminal strips for 24Vdc external power supply and precedence connection, along with warning signal (chime) level adjustment.
