OVERVIEW – THE BENEFITS OF ANALOGUE SUMMING

Having bought the unit, you’ve probably figured out that Sumo is a high-resolution summing amplifier with stereo bus compressor and peak limiter, not to mention a handy little monitor section. Nevertheless, here are a few more interesting and descriptive words with which to impress your inquisitive friends.

In essence, Sumo takes a bunch of signals from several inputs and adds or “sums” them together to present them to one output. This is exactly the same process as takes place in mixing consoles – the mix bus sums signals from all of the channels together.

“But my software has a mixer. Why can’t I just use that?” I hear you cry. Digital summing has one crucial problem; that the output bit depth is equal to or less than each of the internal signals. This means that when signals are summed, some data must be thrown away. Moreover the volume of data discarded in this process increases with your track count. It would, of course be unfair to suggest that modern software performs this data reduction indiscriminately or with especially poor results, however many engineers and producers have found there to be something lacking in their digital mixes – often employing an analogue console purely to make use of its summing bus.

So what’s so special about the mix bus on a big console? Well… only the highest of high end, large format consoles employ balanced mix buses to reduce crosstalk and fend off noise. And this is precisely the kind of mix bus you’ll find in your Sumo, delivering the sound of a large format console without the huge footprint, or price tag.

Not only is Sumo’s summing bus as clean as a whistle, it has frighteningly high headroom. This is particularly important because adding signals means adding their levels, too. The more signals you add, the more level you’re likely to find on the sum bus. Consequently, Sumo has been designed to handle levels in excess of +28dBu.

Summing Amplifier specifications

A Sumo Summing Amplifier is a specialized audio device designed to combine multiple audio signals into a single output while maintaining optimal sound quality and dynamics. These amplifiers are widely used in professional audio settings, such as recording studios, live sound reinforcement, and broadcast environments, where multiple audio sources need to be mixed together seamlessly.

One of the main features of a Sumo Summing Amplifier is its ability to achieve high headroom, allowing for a clean and powerful mix without distortion. This is particularly important in high-dynamic-range audio applications, where maintaining audio fidelity is crucial. The amplifier typically incorporates low-noise components to ensure that the signal remains clear and free from unwanted artifacts.

In terms of technology, Sumo Summing Amplifiers often utilize a combination of analog and digital processing. This hybrid approach enables users to benefit from the warmth and character of analog circuitry while also taking advantage of the precision and flexibility provided by digital signal processing (DSP). Many modern Sumo amplifiers are equipped with programmable features, allowing for customized mixing and routing of audio signals.

Characteristics of Sumo Summing Amplifiers can also include multiple input channels, offering extensive connectivity options. Users can connect various sources such as microphones, instruments, and playback devices, making it suitable for diverse applications. The user interface is generally designed for ease of use, with intuitive controls and visual indicators to help operators manage levels and monitor signal integrity efficiently.

Moreover, Sumo Summing Amplifiers tend to feature robust build quality and durable components, ensuring longevity and reliability in demanding environments. They often include options for EQ adjustments and dynamics processing, enabling users to fine-tune the audio mix to their liking.

In conclusion, Sumo Summing Amplifiers are essential tools in professional audio mixing, offering powerful features, a blend of analog and digital technologies, and high-quality signal processing capabilities. Whether in a studio or a live performance setting, these amplifiers are integral to achieving rich and balanced sound outputs that meet industry standards. As technology continues to evolve, Sumo Summing Amplifiers will likely integrate even more advanced features, further enhancing their functionality for audio professionals worldwide.
