The DL431 is a 6U 19-inch rack fixed configuration unit which features 24 mic / line inputs. Each input feeds three separate preamps, two with separate gain controls, the third being fixed gain. The two variable-gain preamps feed separate ADCs which then pass 96kHz digital audio to the AES50 ports. Four discrete AES50 outputs supply dual redundant digital audio to AES50 networks, and allow for easy connection to any AES50 device. Two balanced analogue splits are provided on the rear panel. The third, fixed gain, preamp feeds a transformer isolated split on the front panel for recording or broadcast applications. The two variable gain pre-amps are remote controllable from two separate locations e.g. FoH and Monitor positions. Front-panel controls and local monitoring with integral headphone amplifier also makes the DL431 usable as a stand-alone device. Integral dual-redundant power supplies ensure peace of mind at all times.
