Technically, the S4000-ProPower occupies a special position because it marks the transition to the ultra-high-end range and thus also cuts a good figure in many recording studios.  It is likewise a classic StromTank, and now in its latest version also one with 16 LFP-batteries (48 Vdc system) and two inverters. These inverters are responsible for limiting the power draw. The maximum current of the DC/AC converter must be taken into account, as well as the heat generated during conversion.

In the S4000-ProPower, two such high-performance converters work in parallel to be able to provide the corresponding power. This has the advantage that each only has to process half the current and the heat is distributed over a larger area. The regulation of load peaks also takes place at twice the speed. In order to ensure optimal heat dissipation, the dimensions of the housing (in relation to S1000-SourcePower & S2500-Quantum) have been significantly enlarged. In addition, black anodised aluminium is used for the outer shell in combination with internal heat distributors made of copper.

As the second largest StromTank, the S4000-ProPower can also supply a complete large system with clean power. Another additional benefit describes the final ideal solution: an S4000-ProPower supplies all analogue devices of your stereo system, while an S1000-SourcePower in combination with the SEQ-5 power strip or an S2500-Quantum exclusively takes care of the needs of digital sources. That’s why we designed the S4000-ProPower so that two StromTank units can be operated one on top of each other. Consistency is a question of attitude. We know what you think about the best possible sound.
