POWERPLAY PRO HA4400
5.6 Connecting multiple headphones
All of the four stereo amplifiers feature one front and one rear panel headphone output connector. Multiple
headphones can be connected per channel, on condition that the resulting connection impedance does not fall
below 100 Ohms. As the power amplifiers are resistant to temporary short circuits, an impedance drop will not
cause any damage, however, it can affect the quality of reproduction, in terms of long-term damage and
distortion.
Additional headphones can be connected to the front panel headphone outputs, even if the unit is installed in
a rack with fixed cabling. If you wish to connect more than three headphones per amplifier, it is advisable to use
a split box or appropriate “Y“ cables. Please find additional information on how to connect the headphones in
chapter 3, and note that the minimum connection impedance of 100 Ohms is maintained.
