Our pre-amp is built around the capabilities and feature set of the MiniDSP 2x4HD processor board. This gives us the power to process the stereo audio stream in real time to perform room correction and digital crossover functions. Room correction technology is powered by Dirac Research AB, world leaders in this field. The Dirac Live platform combines powerful and flexible capabilities with an easy to follow measurement process. 

In brief, this process maps out the frequency and impulse response characteristics of the loudspeakers in the room in a 3D grid around the listening position, using a series of frequency sweeps recorded by a supplied measurement microphone connected to a PC running the measurement utility. After completing the measurements, the summed frequency response is displayed, and a target or desired frequency response curve can be superimposed over the measured data and a set of filters generated to map the two together. Impulse response is also optimised during this process.  This data is then uploaded to the unit and stored in one of four configuration slots, which can be easily activated via the unit's remote control or via the software utility. This provides great flexiblity in that up to four combinations of tonal response, crossover parameters and optimal listening position can be stored and readily recalled.

To get the best from the MiniDSP hardware, we developed an active analog volume control board to provide the best approach to gain structure, ie. maintaining volume control in the analog domain, before power amplification. A custom linear power supply for the volume control and DSP boards ensure top audio performance.

An on-site expert calibration service is included in the price for local customers in order to get the best possible outcome for your situation. In situations where this is not practical, we will offer a one-on-one video call to guide you through the procedure and any subsequent tuning required to get you up and running.
