Expansion Rack

Rack-mount for Phonitor 3, 

The SPL Expansion Rack is not only a 19” rack housing for the Phonitor 3, it also expands the connection possibilities.

A passive four-way switch integrated into the Expansion Rack allows the speaker output signal to be switched between up to four stereo speaker pairs.

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.

If the Expansion Rack is to be placed freely and not installed in a rack, the rack ears of the Expansion Rack can be removed. The feet of the installed device can be screwed into the bottom of the Expansion Rack.
