Input Section

MONO Buttons – Under normal circumstances, all of the odd numbered channels entering Sumo are routed to the left side of the bus, while even numbers are routed to the right. Of course, this is going to sound a little unusual if your kick drum appears on the left and your snare is on the right, etc. So the first two channel pairs (1/2 + 3/4) can each be mono’d, effectively panning them dead centre, right where you want them. Also, routing mono sources through a single channel saves outputs from your DAW.

Mix Gain – This control gives you a pre-dynamics gain trim from –20 to 0dB, so even if you’ve been especially normalize-happy whilst editing, you won’t have any problems with headroom, either within Sumo or, more likely, with any attached inserts.

MIX INSERT Switches – These buttons refer to the insert connections on the back panel. Use these if you want to add your own EQ, compression, or anything else you can think of. The ‘In’ switch puts the inserts in circuit, breaking the signal path if nothing is connected.

The ‘Post Dyn’ switch allows you to alterthe position of the inserts in the chain: before (pre) or after (post) the internal compressor and limiter.

!Be careful of boosting with an inserted unit when in post-dynamics mode as the limiter is no longer able to protect the output level. This is

particularly important with digital gear, where overs must be avoided at all costs.

Output Meter – This meter will display system output level in dBu for either the main sum bus or two track input; whichever is selected in the monitor section. Or whichever source you are listening to, if you like. The legend beneath the meter shows how the analogue levels relate to digital output when the digital card is installed. If you wish to line the analogue inputs of your digital gear up to match the meters, 0dBu should equate to –24dBFS.

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.
