Pre-amplifiers

With this DSP audio quality being of an exceptional standard it is necessary to design the pre-amplifier circuit very carefully. The pre-amplifier circuit is a very unique and specialist design featuring an exceptional input range and a maximum input of +33dBu!! Coupled with this is the use of a hardware input limiter before the ADC (Analogue to Digital Converter). This allows for unexpected changes in level to be "smoothed" before they reach the conversion stage. This means that the ADC will be protected from high transients with good audio quality. Without the ADC high transient could distort the ADC resulting in a distorted signal being fed through the system to the outputs. The limiter can be switched on or off as required.

The preamp stage has gain control (in 3dB steps), Phantom power and a -20dB Pad.
