The two-mode switch: Led/SI mode (the abbreviation of Light Emitting Diode/Silicon), belongs to light emitting diode and silicon tube clipping type, in which its distorted tone plays as strong low frequency and natural midfrequency. SI (the abbreviation of Silicon), belongs to silicon tube clipping mode that, in which its distorted tone plays as solid low frequency and deep midfrequency. In order to make our products durable and generate a timbre of good quality, we use PCB made of RF-4 material by plug-in processing, trying to let it play the needed timbre. Electronic parameter: Working voltage: DC9V(usual 8V-15V) working currency: 2.5mA Input impedance: 52 ohm Output impenance: 50 ohm Battery:self-provided(Sorry, the airline doesn't permit.) Case material:aluminum alloy Packing size(mm): 160x93x70 Weight(g): 322
