The Product

The Sonifex RB-HD6 is a 1U rackmounting headphone amplifier which distributes stereo audio up to six different sets of headphones, or can be used as 6 independent headphone amplifiers, each having their own input and volume control. A typical application might be to provide common headphone feeds for guests in a radio studio, with a separately derived feed with cue for the presenter. The main stereo input is on the rear panel and is presented on XLR connectors which are electronically balanced but can be wired unbalanced if required. A stereo/mono input select switch on the rear panel sums left and right outputs to provide a mono feed to the headphones. Each channel has an individual input on a ¼" Jack which will overplug the main stereo input to each channel as required. These override audio inputs can also be individually configured as parallel outputs by setting internal jumpers. The master volume control adjusts the overall headphone level but can be disabled internally if required.
