The 16 inputs are connected via two Tascam DA88 type female D-Sub connectors. Interconnect cables are readily available in pre-wired form from Audient and from any good cable manufacturer. You can get these with different tail types to suit your other equipment, see the accessories section on page 18. Always use balanced connections to reduce any cable interference and noise.

Note: All undesignated pins are unconnected. All screen connections are joined inside the unit and connected to metalwork earth.

Outputs are provided on male XLR connectors: two for the main outs and two for your monitors.

Inserts are connected via TRS (Tip-Ring- Sleeve) jacks. Rather than an unbalanced loop on a single cable, there are separate jacks for sends and returns, providing balanced connections throughout.

A third D-Sub connector (which breaks out to XLRs) can provide extender linking and an external monitor input. The first two channels connect the external input to the monitor section, while the remaining three pairs of channels allow additional Sumo units to connect directly into the mix bus.

All of Sumo’s analogue audio connections operate at +4dBu, the professional standard, so you may need to ‘pad’ outputs fed to semi-pro equipment.

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.
