The SM2558 redefines Out of The Box stereo summing in a sleek, 500-series compatible unit.
With 10 active balanced inputs, it empowers your mixes with unparalleled clarity in the pure analog domain.
Experience zero-latency direct monitoring for an intuitive, efficient workflow.
Equipped with API Style discrete operational amplifiers and NOS transistors, it ensures exceptional signal summing quality.
Outputs are enhanced with custom Augmented HRK Active Transformers to deliver Classic Analog Sound.
Flexible routing and a Vintage Drive offer creative mixing options, adding warmth and depth.
Available directly from HRK Shop, the SM2558 combines professional-grade features with outstanding value, making high-end mixing accessible.
The SM2558 can be used even with stereo or two outputs audio interface.
You don’t need to wait until you’ll upgrade to a multi-outputs interface to benefit from the Analog Vintage Sound of the SM2558 Summing Mixer.
The SM2558 can be used as a Mastering Tool for a Stereo Mix. If a stereo signal is sent to the front panel Stereo Inputs, it will be enhanced by the analog circuitry and added harmonics content.
This simple process will upscale your music production eve if you are less experienced in Audio Engineering or not yet equipped in an expensive studio gear.
The analogue summing of all 10 inputs is processed with the Class A Discrete Operational Amplifiers.
The Opamps used in the SM2558 are inspired by the famous British design from the ’70s.
The SM2558 Discrete Opamps are made with selected NOS components.
The Vintage Drive Mode is designed to emulate the characteristic sound of vintage mixing consoles by adding harmonics through the saturation of the Discrete Circuitry.
This feature enriches the signal without overdriving the output transformers, next in the signal chain device, such as Audio Interface.
This approach ensures the high fidelity of the mix, maintains equal signal levels, and avoids digital clipping.
The result is a mix enhanced with even harmonics, bringing out a richer bottom-end, creating space between mix elements, and producing a more vivid sound scene.
Engaging the Vintage Drive is made simple with a switch located on the front panel, allowing for easy access to this classic sound enhancement.
Traditional passive transformers are known to be vulnerable to electromagnetic interference, such as 50/60Hz hum and HF RF smog. Additionally, their frequency response is contingent upon load and source impedance, which adversely affects the overall performance of analog studio equipment.
The HRK Active Transformer is a game changer that not only resolves the issues associated with passive transformers but also retains and amplifies the desired characteristics of the transformer output stage. This includes the enrichment of harmonic content and the enhancement of tonal response.
What sets the HRK Active Transformer apart is its ability to deliver the rich, beloved sound that audio enthusiasts seek, including the harmonic content and tonal response, while simultaneously eliminating the drawbacks of passive transformers.
Utilizing a single slot in the 500 rack for stereo mode might seem unconventional, yet it is entirely feasible and safe.
The XLR input connector on the 500 rack’s rear panel functions as a direct connection from the XLR socket to the module’s PCB edge connector, making it simple to convert to an output using the provided XLR male-to-male adapter.
The arrangement for this setup is illustrated below, demonstrating how the rear panel XLR connectors can be adapted.
The necessary XLR male-to-male adapter comes included with the SM2558.
It’s important to note that if your 500 rack includes any additional routing features, these should be disabled to ensure the proper operation of the SM2558.
