Product information

Description

The Omnitronic 80709786 Performance/stage Black audio amplifier provides a robust solution for live sound and installed audio applications. Designed with a Class A/B output stage, the amplifier delivers up to 250 W peak power per channel while maintaining low distortion. Compact rack-friendly dimensions and clear front-panel LED indicators for power and fault status make it suitable for stage rigs and fixed installations where clarity, reliability and straightforward operation are required.

Advantages

The Class A/B topology balances sonic performance and thermal efficiency, achieving a low Total Harmonic Distortion (THD) of 0.5% for accurate audio reproduction. Clamp-style speaker terminals ensure secure and fast speaker connections without special tools. A standard 230 V AC, 50 Hz mains supply and a typical power consumption of 500 W allow integration into common European power environments. The units compact 1U rack height and robust construction support transportation and rack mounting in performance setups.

Suitable for

  • Small to medium live sound reinforcement for stages and performance venues
  • Fixed audio installations in clubs, bars and event spaces
  • Monitoring systems for rehearsals and studio environments
  • Portable PA systems where rack-mountable amplifiers are required

Key specifications

  • Amplifier class: Class A/B
  • Peak output power: 250 W per channel
  • Total Harmonic Distortion (THD): 0.5%
  • Mains input: 230 V AC, 50 Hz
  • Typical power consumption: 500 W
  • Speaker connections: clamp terminals
  • Dimensions (W x D x H): 483 mm x 385 mm x 89 mm
  • Front-panel indicators: power and fault LEDs

How to use

Install the amplifier in a standard 19-inch equipment rack using the 1U height form factor, or place it on a stable surface with adequate ventilation. Connect the amplifier to a 230 V AC, 50 Hz mains supply and switch the unit on using the front-panel power control. Use the clamp terminals to attach speaker cables securely, observing correct polarity. Feed input signals from a mixer or source device at appropriate levels, and monitor the front-panel LEDs for normal operation or fault indications. Allow the amplifier to reach operating temperature before high-power use to ensure stable performance.

Usage recommendations

For reliable long-term operation, ensure adequate rack ventilation and avoid obstructing airflow around the amplifier. Use correctly rated speaker cables and protect the system from short circuits or sustained overloads. Regularly check connectors and LEDs to detect early signs of faults; if the fault indicator activates, power down the unit and inspect connections and load before further use.

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%.

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.
