Input can be shared with additional amps or different inputs can be used

The OSD Audio PAX50 is a small format, 70/100-volt amp, that provides great flexibility for designing your commercial audio system. If your system needs more power or additional zones are needed, additional amps can be added to the rack, with both source sharing, or separate inputs for each amp. This makes expanding your system much easier. If you have multiple zones, you can share a source to each zone or have a different source in each zone.

This highly featured but small footprint amp has 50 Watts of power and is capable of powering 8 speakers tapped at 5 Watts.

Two amps can be used together to create stereo zones where left and right signals are desired.

The PAX50 is a Class D amp and is designed to run cool, this is ideal for rack mounting or other areas where ventilation is restricted. They also use a fraction of the electricity used in class AB amps.
