With the Expansion Rack, a desktop device, such as the Phonitor 3, can be installed in a 19-inch rack. All compatible devices are installed in the same way. Detailed, illustrated installation instructions can be downloaded a little further down on this product page.

 

The Expansion Rack is equipped with a rotary switch that passively routes the stereo output signal of a built-in device to four stereo outputs. Switching takes place passively, i.e. without active electronics in the signal path and without a power supply. Phonitor 3, Phonitor 3 DAC or SMC 7.1 are expanded with three additional stereo outputs together with the Expansion Rack so that for example full-range, midfield and nearfield monitors can be connected.
