means of a mechanical switch. In ‘redundant’ mode the unit
shall provide full redundant connection to the Mixrack or
Surface. In ‘cascade’ mode the unit shall allow series
connection of two units.
The Ethernet protocol shall provide control to the remote
preamp, and all mic preamps are scene recallable by the
digital mixing system. Unit firmware shall automatically be
updated or downgraded when connected to the digital
mixing system.
The remote audio rack shall have a robust steel chassis and
shall be designed to be placed in different mounting options
including NEMA12x12” box, horizontally or vertically, flush or
straight mount.
The remote audio rack shall have a built-in power supply
accepting AC mains voltages of 100~240V, 50/60 Hz, 35W
max via an earthed 3-pin IEC male connector or thru an
optional screw terminal with Cable gland mounted on the
rear chassis. Secondly there needs to be a 12V DC power
connection which can be used as primary power supply or
