DI boxes can rightfully be considered one of the most popular devices in the stage and sound recording field. Their main function is to convert the unbalanced output of a musical instrument into a balanced one for further transfer via cables to the desired device – a mixing console, sound card, etc. Also, DI boxes perform a number of such functions necessary for the signal to arrive without loss or distortion, as ground lifting and proper signal amplification. But, if the solution to the first problem was largely a trivial issue for the passive type of diboxes, then lossless signal transmission is the cornerstone of such devices. On the other hand, active diboxes successfully cope with the loss problem, but due to technical implementation, ground lifting is difficult for them, since active devices require phantom voltage, which, as a rule, is supplied from the mixing console and, as a result, exclusion of this power supply do not allow ground lift without using separate power sources, which makes such devices extremely inconvenient to use on stage. Thus a vicious circle is obtained.
After meticulously market investigation, and attempts to find something that could solve problems mentioned above, we decided to approach the issue from a completely different perspective, and tried to craft devices, which technical decisions are fundamentally different from any of the competitors.
The first and very noticeable aspect, which differs our devices from others is that on a first stages of development we abandoned the use of operational amplifiers completely, therefore, the entire amplifying part of Simpleway DI boxes is developed only on discrete elements. In simpler terms, the advantages of this implementation are not only the preservation of “air” in the instruments, but also the absence of distortions in the low-frequency region, which allows you to maintain the density and solidness of the instrument.
The second difference is the linearization of individual transistor cascades and their small application. In fact, our devices have a high-impedance input stage, which allows you to convert any unbalanced signal into a balanced and low-impedance power amplifier without distortion, and, as a result, gives an opportunity to transfer the signal from the DI box output to multimeter cables without noticeable signal degradation. In other words, our devices work perfectly with wires of any length, which makes it possible to use them not only in small venues, but also in arenas and stadiums without any problems.
The third and important feature of our device is the stable operation with poor quality phantom amplifiers. Thanks to our unique solution, the device is able to adapt the operation of the circuitry depending on the incoming power, which makes it possible to work even at + 24V with minimal loss in sound. It is worth noting that in such extreme cases, the device may show power indication absence, but at the same time it will save from the loss of sound. In addition, each DI box is equipped with the Simpleway Ground Safety option, with which the device indicates a grounding problem.
All of the above aspects makes our DI boxes indispensable and reliable devices, capable to ensure impeccable and high-quality work in any conditions.
