8PAKAMP kit is a 8 channel version of our popular 60W AMP kit. We originally designed the 8PAKAMP for a large Dolby Labs project we did a while ago. 

• 8 x 75Watts of power configurable to lots of combination (eg 4 x 140watt bridged, 2 x 280watt bridged, 1 x 560watt bridged, 1 x 280watt bridged + 1 x 140watt bridged + 2 x 75watt. etc)
• 2 x 8000uF 50v capacitor power rail smoothing banks on board PCB. So only power transformer, Bridge rectifier and heatsink needed to complete full 8 channel amp.
• Fully balanced inputs to all amps (can be wired unbalanced in by shorting either +in or -in to 0v depending on amp phase needed)
• Amp level setting trims on all channels. Can be fitted under the PCB for external front panel trimming or on top of PCB for internal trimming.
• Inputs can be PCB XLR or TRS sockets or hard wire
• Amp IC's can be fitted flat under PCB or vertical standing on top of PCB for different heatsink setups.
• PCB measures 184mm x 81mm
