Feature: 1. TECHNICAL PARAMETERS: The input and output of the active sound distributor are 3.5mm interfaces, dual channel signals, gain 3.5db, input impedance 100K, output impedance 16Ω‑600Ω, maximum output power is 32Ω/500mw 2. INPUT AND OUTPUT: 2 way active sound distributor one way input and two way output simultaneously. The output can be connected to sound devices such as headphone or sound amps, and the volume will be independently adjusted 3. STRONG DRIVE AND HIFI: Sound distributor adopt for JRC NJM4556A high current dual op amp chip, strong drive capability, high fidelity and dynamic 4. ISOLATION AND INTERFERENCE RESISTANT: Power supply voltage DC5V, static working current 100mA, the machine has a built in isolation boost power supply, the 5V voltage into positive and negative 9V for the internal circuit to provide working voltage, although the power part has been optimized filtering, it is still recommended to use excellent pure power supply, can ensure that the sound is clear and beautiful without interference 5. EROSION RESISTANT ALUMINUM ALLOY: Active sound distributor is made of excellent aluminum alloy material, light weight, possess good strength and good erosion resistance Specification: Item Type: Active Sound Distributor Model: AU 102 Material: Aluminum alloy Input Output Interface: 3.5mm Power Supply Voltage: DC5V Static Working Current: 100mA Gain: 3.5dB Input Impedance: 100K Output Impedance: 16Ω-600Ω Maximum Output Power: 32Ω 500mW Size(LxWxH): Approx. 65 x 53 x 25mm / 2.56 x 2.09 x 0.98in . Package List: 1 x Active Sound Distributor 1 x Data Cable
