The Omnitronic XDA-1204 is a versatile and feature rich 4 channel Class D amplifier designed for use in PA systems.
The amplifier has can be used in 4 ohm, 8 ohm or 100V modes. The output at 4 ohms is 4 x 300W, this means each of the four channels can deliver 300 watts of continuous power to a 4 ohm load. At 8 ohms the output is 4 x 180W similarly, it can deliver 180 watts per channel to an 8 ohm load. The amp can also be bridged at 8 ohms or 100v, When bridged at 8 ohms two channels can be combined to provide 600 watts to an 8 ohm load or the 100V option allows the bridged mode to deliver 2 x 600 watts at 100 volts.
The switch mode power supply (SMPS) is known for its efficiency and compact size. This helps reduce the overall weight and height of the amplifier, making it more portable and rack-friendly.
The amplifier has 3 operating modes giving full flexibility of use. Stereo mode, each channel operates independently, which is useful for distributing audio to different areas or speakers. Parallel, channels can be paired in parallel to increase the power output to a single set of speakers. This can be handy when you need more power in specific areas or bridged mode which combines channels to create a single, more powerful output, which is useful for driving larger speakers or subwoofers.
Each channel offers level controls which allow you to adjust the input level for each channel individually. This level of control can help you fine-tune your audio setup.
The amplifier is 19" rack mountable & occupies 1U (1 rack unit) of space. This makes it easy to integrate into existing audio setups.
The presence of status LEDs allows monitoring for power, signal, clipping and bridge mode.
Overall, the OMNITRONIC XDA-1204 is a versatile and compact solution for audio amplification in PA systems, catering to various power needs and configurations. It's essential to follow the manufacturer's instructions and guidelines for safe and optimal use, especially when configuring it in different operating modes and adjusting levels.
