Active Digital Rererencestudiomonitor

 

The ADM 20 represents a complete revision of the very successful ADM 2, which was the first loudspeaker with a digital equalizer worldwide. Naturally we have retained the valued neutrality in transmission behaviour as well as the now legendary frequency and phase characteristics. The specially developed and patented FIRTEC ™ filter technology allows for corrections during the course of the sound emission. This means a flattening in amplitude as well as in the phase frequency characteristic.

 

On top of this, the precision is increased with a higher sampling rate combined with a whole series of parameters and their different possible configurations which are accessible to the user. For example, these include three parametric peak filters to facilitate the exact adaptation to the equipment positioning, low and high shelving, delay as well as phase and monotest functions. At the same time, the FIRTEC ™ filtering not only compensates for any inadequacies of the drivers, but also considers the whole monitor system including cabinet, amplifier etc. At the analogue input, the signal is converted with a 27 bit ADC (gain staging method). The digital AES3 input works with up to 32 bit directly on the 32 bit floating point DSP with the FIRTEC ™ filter, the digital, linear phase, differential crossover unit and overload protector of the drivers. An optional hardor software remote control facilitates the adjustment of the volume to the required level or setting up the peak filter in order to reduce the spatial responsiveness for room modes or other variables. The connection to the remote PC can optionally be set up via wireless LAN if so
required.
