SM2558 | Fully Featured Stereo Summing Mixer

The SM2558 is an Active Stereo Discrete Summing Mixer unit which fits in a single 500 rack space.

The SM2558 has a total of 10 active balanced summing inputs which can be used to mix any music material in the Outside-the-Box Analogue Domain.

The Direct Monitoring feature helps to save the outputs of an audio interface and provides seamless workflow without the latency!

The stereo summing bus section is based on the Discrete Operational Amplifiers made with NOS transistors.

The Outputs of the SM2558 are coupled with custom HRK Transformers powered by Class A Discrete Drivers.

Flexible routing allows to assign summing inputs to channel LEFT, RIGHT or LEFT + RIGHT summing bus.

The Vintage Console Mode adds more harmonics by increasing the saturation of the output transformers.

The SM2558 is a compact, yet fully functional summing mixer, with features which can be found only in very expensive studio mixers!

Direct Sale allows us the keep the price low and passes the saving on the distributor fees to our Customers!

Use the SM2558 with a Simple Audio Interface!

The SM2558 can be used even without the D25 split cable, with a simple two-channel audio interface.

The front panel TRS inputs can be used to process any stereo signal.

Simply connect the inputs and outputs of your interface, run any track or finished the mix with SM2558 and get the analogue warmth of Class A Discrete Circuitry and Output Transformers.

All you need are the standard TRS cables!

Discrete Operational Amplifiers Summing Bus

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.

Vintage Console Mode

The Vintage Console Mode adds the harmonics to the signal by saturating the output transformers, typical for the vintage mixing consoles.

The output transformers are not overdriven by the higher signal level.

Special Class A Discrete, open feedback circuitry is used to power the output transformers.

Such solution ensures the high fidelity of the processed mix, equal signal levels and prevents the digital clipping.

The signal is enriched with even harmonics resulting in enhanced bottom-end, space between the mix elements and vivid sound scene.

The Vintage Console Mode can be engaged by the switch on the front panel.

Direct Monitoring

The Direct Monitoring feature helps to save the outputs of an audio interface.

The Direct Monitoring function allows to edit, listen and process the mix at the same time without the latency.

The MON switch converts the front panel TRS sockets into the Direct Monitoring outputs.

The front panel TRS sockets mirror the signal available on the main rear panel outputs.

You can connect the studio monitors and use all interface outputs for mixing.

No cable switching, just seamless workflow without the latency!

The use of the 500 single slot in a stereo configuration.

It might be counter-intuitive to use a single slot of the 500 rack in stereo mode. Nonetheless, it is absolutely possible and completely safe.

The 500 rack rear panel XLR input connector is nothing more than a straight-wire connection between the XLR socket and the 500 module PCB edge connector. Therefore, it can be easily converted to the output with the included XLR male-to-male adapter.

The picture below shows the arrangement of the rear panel XLR connectors. The XLR male-to-male adapter is included with the SM2558.

NOTE: If your 500 rack has any built-in extra routing features, remember to disable any routing options before the use of SM2558.
