These days, more and more educational institutions such as colleges, universities and high schools are expected to provide downloadable recordings - podcasts - of lectures and classes, for students to access at all times on the local area network. These recordings are typically taken from the classroom/lecture theatre sound system and saved to a computer in real time.
Problem 1: Getting the correct recording level is hard, given that the level requirements are different to those of speakers.
Problem 2: Maintaining a steady input level to the computer requires continual monitoring to prevent digital overload.
The new UniFace 'Universal Interface' from ARX: A user-friendly way of adapting existing systems to be ‘podcast-ready’ by simply inserting it into the existing signal chain.
Automatic Gain Control
Two Balanced XLR Line input channels feeding into the Automatic Gain Control circuitry taken from our unique UniMIX. Specially tailored parameters ensure that levels remain constant, irrespective of Mic placement and user technique.
The result is a consistent level for the recording, removing the need for fulltime monitoring and the risk of overloading and distortion.
The Recording Outputs are stereo balanced XLR connectors, transformer isolated to prevent ground loops and associated noise.
For the room system, the UniFace has 2 Balanced XLR outputs, looped from the Balanced Inputs. The Input and loop Output XLRs are hardwired so there is no interaction with the existing room system.
Industry standard connections ensure that the UniFace neatly and compatibly interfaces with existing systems with no wiring modifications being required
Wide Dynamic Range
Internally, careful attention to the signal path design, using precision components found in high-end mixing consoles, has resulted in a unit with very wide dynamic range. The UniFace has enough headroom to cope with the hottest line signal, and better than digital noise specifications
Universal AC Power
AC power range is a universal 100 to 120V or 220 to 240V AC, and is connected to the unit via a standard three pin IEC connector, with built-in fuse and voltage change switch.
Other applications include Boardroom/Annual General Meeting recording, Courtroom, Houses of Worship, and much more.
