Product function introductionA977 passive preamp active speaker volume dual-channel controller is small in size and suitable for active speakers or preamp/post-amp, it supports full-balance or input and output of single-ended signal. The product has functions of independent L/R channel volume adjustment, 2 signals input and 2 signals output. It provides balanced XLR and unbalanced RCA connectors which are automatically converted to each other, with a selector switch facilitates the signal switch of input/output.Small size, big intelligence. The product is of small size, but has well-function connecters. It is suitable for decoders and speakers without volume adjustment. the product has the design of balanced input/output and RCA input/output architecture, with switching function. The operation of the product will not cause loss of signal source. Generally, the audio signal released from the decoder is the original sound source signal. Great dynamics will not cause loss of sound quality, retaining the complete original signal source.Product parametersInput/output impedance: 10KΩ - 50KΩ2 in 2 out switchover, unbalanced RCA connector and balanced XRL connector for input/outputInput: unbalanced RCA connector / balanced XLR connector (convert selection)Output: unbalanced RCA connector / balanced XLR connector (convert selection)Product net weight: 0.32 kgProduct package weight: 0.42 kgProduct dimensions: length 145mm X width 65mm X height 43mmPackaging dimensions: length 200mm X width 180mm X height 55mmKit list1 X A977 2 In and 3 Out Switcher Full-balance Passive Preamp Active Speaker Double Sound Source Volume ControllerSpecification: Package Weight One Package Weight 0.48kgs / 1.06lb One Package Size 16cm * 16cm * 5.5cm / 6.3inch * 6.3inch * 2.17inch Qty per Carton 35 Carton Weight 15.00kgs / 33.07lb Carton Size 52cm * 52cm * 17cm / 20.47inch * 20.47inch * 6.69inch Loading Container 20GP: 580 cartons * 35 pcs = 20300 pcs40HQ: 1346 cartons * 35 pcs = 47110 pcs
