About The ProductAlmost all 60Hz AC buzzing is caused by earthing loops and acts like a radio antenna (ring antenna). The buzzing noise canceller completely eliminates this by disconnecting the grounding circuit, making the signal line unable to absorb the AC buzzing and noise first. Compared with balanced circuits, unbalanced circuits are more susceptible to current noise and RF interference, the longer the unbalanced cables are, the more likely problems are. Using this device to connect two devices is one of the most economical and effective methods to convert between unbalanced signal and real balanced signal. Automatically convert signal voltage to match ground potential difference.Features1. 60 Hz noise cancellation, eliminating AC buzzing noise. 2. Safety earthing breaks the grounding cycle, keeps the highest sound quality. 3. Passive equipment: No power supply, high performance ultra compact design. 4. Four channel stereo 6.35mm and XLR and 3.5mm and RCA signal inputs and outputs. - A set of input and output 6.35mm TRS signals. - A set of input and output XLR signals. - A set of input and output 3.5mm signals. - A set of input and output RCA signals. 5. Note: there is no multi-channel stereo input and output at the same time. 6. Fever grade high quality components and very sturdy structure. 7. Automatically converts an unbalanced signal to a balanced signal without any signal loss. 8. Use the 11:1 isolation transformer to disconnect the ring antenna and the balanced audio line.Specification: General Model B890 Material Metal Product Size 115*100*37mm Weight 450g Package Weight One Package Weight 0.61kgs / 1.33lb One Package Size 22cm * 20cm * 6cm / 8.66inch * 7.87inch * 2.36inch Qty per Carton 20 Carton Weight 12.65kgs / 27.89lb Carton Size 42cm * 38cm * 30cm / 16.54inch * 14.96inch * 11.81inch Loading Container 20GP: 556 cartons * 20 pcs = 11120 pcs 40HQ: 1292 cartons * 20 pcs = 25840 pcs
