Omnitronic XPA-700 -päätevahvistin

The Omnitronic XPA-700 is a 2.0 channel power amplifier designed for live sound and installed audio applications. It delivers peak output of 350 W per channel using A/B class amplification, accepts AC mains at 115/230 V and includes clamp-type speaker terminals for secure cable connections. The unit's compact chassis (483 mm width, 354 mm depth, 89 mm height) and LED power indicators make it suitable for rack mounting and quick visual status checks during performances.

Advantages

The amplifier combines A/B class topology with high peak power capability to provide reliable transient response and sustained output for loudspeaker systems. Its compact rack-friendly dimensions save space in mobile rigs and fixed installations. Clamp terminals simplify speaker hookup while minimizing contact resistance, and the power status LEDs allow operators to verify operation at a glance. Typical power consumption is around 495 W under normal operating conditions, giving an expectation of energy use during events.

How to use

Install the amplifier in a standard 19-inch rack using appropriate mounting hardware, ensuring adequate ventilation around the chassis. Connect the amplifier to the mains supply matching the local voltage (115 V or 230 V) and verify fuse or circuit protection as required. Use appropriately rated speaker cables and secure them in the clamp terminals, observing correct polarity. Feed the input signals from a mixer or line-level source, set channel gains to unity, then increase output gradually while monitoring speaker and amplifier behaviour. Observe the LED indicators for power and operational status during use.

Recommendations

To maintain performance and safety, allow sufficient airflow around the unit, avoid overdriving the channels for prolonged periods, and use speakers with compatible power ratings and impedance. Regularly inspect clamp connections for tightness and check mains connections before extended use.
