Drumfire DF-500 DRUM SYNTH with Original Box

via this auction
"The Drumfire DF-500 is a 5 channel drum synth module. The 5 channels are identical, with their own Trigger-In and Audio Out sockets. Each channel is a mini analogue synth drum module, capable of producing a wide range of electronic drum sounds, and since every parameter is defined by a knob, it's highly tweakable. The 5 drum channels also have their own level and pan pots, and the signals are mixed to a pair of stereo outputs with Left/Right volume control. Each channel has 9 controls (8 knobs & 1 switch): -SENSITIVITY controls pickup/trigger in sensitivity -OSCILLATOR DECAY controls decay time of the synth oscillator -NOISE DECAY controls decay time of the noise sound -SWEEP alters oscillator frequency -PITCH changes oscillator pitch -BALANCE controls balance between oscillator/noise -VOLUME output volume to mixer -PAN L/R balance control, also allow dual output on L/R jacks"
