Product information

Description

The Omnitronic MPZ-180.6 ELA mixer amplifier in 19" format is designed for public address and ELA (electro-acoustic) sound reinforcement systems for both mobile and fixed installations. It provides six mixable inputs that accept up to three microphones and three line-level devices, and offers outputs for 70 V and 100 V constant-voltage speaker lines as well as for 4–16 Ω low-impedance loudspeakers. A line output is available for connecting an external device such as a mixing console.

Advantages

The unit combines mixer functionality with an integrated amplifier in a compact 19" housing, enabling flexible deployment in racks or stand-alone setups. Multiple output options (70 V, 100 V and 4–16 Ω) cover common ELA and low-impedance speaker configurations, while six mixable inputs allow simple routing and simultaneous connection of microphones and line-level sources. Zone outputs can be switched individually from the front panel to adapt coverage as required.

Suitable for

  • Public address systems in schools, offices and retail
  • Background music and paging in hotels and restaurants
  • Small to medium fixed installations and mobile sound systems
  • Multi-zone announcements and voice evacuation setups

Key specifications

  • Format: 19" rack-mountable unit
  • Power: up to 180 W peak per channel (see product data for detailed power ratings)
  • Inputs: 6 mixable inputs (up to 3 microphones + 3 line-level devices)
  • Outputs: 70 V and 100 V ELA transformer outputs; 4–16 Ω low-impedance output; line output for external devices
  • Front-panel switchable 6 zone outputs
  • Power supply: 230 V AC, 50 Hz (typical consumption depends on operating conditions)

How to use

Install the MPZ-180.6 in a 19" rack or place it on a shelf in a secure, ventilated location. Connect microphones and line sources to the corresponding input channels and set input levels on the front panel. Choose the required speaker output mode (70 V, 100 V or low-impedance) and connect speakers using appropriate transformer taps or impedance-matched wiring. Use the front-panel zone switches to enable or disable individual zones, and route a line output to an external mixing console or recorder if needed. Adjust master and zone volume controls to achieve the desired coverage and level balance.

Usage recommendations

For reliable operation, ensure adequate ventilation around the 19" unit, use correct wiring and speaker taps for the chosen output (70 V/100 V or 4–16 Ω), and verify input gain staging to avoid clipping. Follow local regulations for paging and emergency audio systems when deploying multi-zone ELA installations.

Amplifier class: An electronic amplifier, amplifier, or (informally) amp is an electronic device that increases the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. Power amplifier circuits (output stages) are classified as A, B, A/B and C for analog designs, and class D and E for switching designs based on the proportion of each input cycle (conduction angle), during which an amplifying device is passing current.

Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.
