Operator Manual
Chapter 1: Introduction
The DL431 Mic Splitter is a six-unit (6U) high 19” rack unit that provides 24 mic/line
inputs. Each input feeds three separate preamps, two of which have separate remote
and local gain controls, while the third has fixed gain. The two preamps with gain
controls feed separate analogue to digital (A/D) converters, which pass digital audio to
the network. Four discrete AES50 outputs supply dual redundant digital audio to front
of house (FOH) and monitor XL8 systems, and allow for easy routing to any third-party
AES50 device, such as a recorder, via DL461 routers.
Two balanced analogue splits — sourced from post-each mic amp — are provided on
the rear panel. The third preamp (fixed gain) feeds a transformer isolated split on the
front panel for recording or broadcast applications.
Front panel control and local monitoring, including integral headphone amplifier,
enhance the DL431’s features, and dual redundant internal power supplies ensure
worry-free operation. Four DL431s are supplied with each XL8 system to provide
96 input channels.
