This chip offers high quality sound and makes the compatibility and integral performance more optimizing. Just use 3-pin XLR to connect console or active speaker, then using Bluetooth® to connect smart phone, pad such devices to realize wireless transmission. STEREO-LINK button helps BX-4 pairing with another BX-4 to transmit the signal to audio equipments. 技术要求与检验要点： 单面尺寸：145x210mm 材质： 105g铜版纸 黑白双面印刷，需折叠 更改记录：V1.1尺寸，材质和地址更改 V1.2功能更改 单位：mm 宁波奥创电子科技有限公司 NINGBO ALCTRON ELECTRONICS TECHNOLOGY CO., LTD Alctron 设计 DESIGNED_BY 核准 CHECKED_BY 工艺 TECHNOLOGIZED_BY 标准化 STANDARDIZED_BY 审核 APPROVED_BY 日期 DATE: 签名 NAME: SHEJI SHENHE PIZHUN GUIDANG SJRQ SHRQ PZRQ GDRQ 1. USB CHARGE: charging interface supply power to devices. 2. POWER ON/OFF: push switch-turns the BX-4 on and off. 3. PAD 0dB -10dB: sensitivity attenuator, lower the input signal sensitivity and avoid signal overload and distortion. 4. CHARGE: battery indicator,during charging the blue light lits, when battery is already full, the indicator goes out. 5. LED indicator: when turn on the BX-4, the product to be paired, red and blue light lit alternation; when paired successfully, blue light flash slowly. When paired and Bluetooth played music, blue light solidly lit; if no music, blue light flash slowly. 6. STEREO-LINK button: press the button(STEREO-LINK) on both BX-4 for 2 seconds, the blue light flash quickly(on both BX-4 LED indicator flash). Each BX-4 searched for each other, when they are successfully paired, one BX-4 red and blue light lit alternation another BX-4 blue light flash slowly(at that time, the output signal is STEREO). 7.

USB CHARGE：充电口给设备提供电量。 2. POWER ON/OFF：电源开关，打开/关闭BX-4。 3. PAD 0dB -10dB：灵敏度衰减开关，降低输入信号灵敏度，防止信号过载出现削波现象。 4. CHARGE：充电指示灯，充电的时候，亮蓝灯，充满时灯灭。 5. LED 指示灯：当您打开BX-4时,产品处于等待配对的状态，此时红蓝灯交替闪；配对成功的时候,蓝灯慢闪。 配对成功且有音乐播放，蓝灯常亮；无音乐播放，蓝灯慢闪。 6. STEREO-LINK按钮：在两个BX-4上按STEREO-LINK键2秒，蓝灯快闪（两个BX-4上的LED指示灯闪 烁），BX-4会自动搜索彼此。当两个BX-4配对成功的时候（此时输出为立体声），一个BX-4红蓝交替闪烁， 一个BX-4蓝灯慢闪。 7. XLR：平衡输出接口。 5. 成功匹配之后，蓝灯慢闪。当匹配成功，蓝牙设备在播放时 蓝灯常亮，无音乐播放，蓝灯慢闪。 1、按两个BX-4上的STEREO-LINK键2秒。 蓝灯常亮 或慢闪 2、两个BX-4上的STEREO-LINK蓝灯快闪，进入 立体声配对状态。 3、两个BX-4产品匹配成功，一个红蓝灯交替闪烁， 一个蓝灯慢闪。 * 版本： * 供电： * 待机电流： * 工作电流： * 温度范围： * 无线传输距离： * 灵敏度： * 频率范围： * 信噪比： * 失真度： * 充电方式： * 待机时长： * 工作时长： * 净重： * 尺寸： Bluetooth V5.0 3.7V锂电池供电 <50uA ≤10mA -40°C--- +80°C 10m -95dBm<±0.1% BER 2.4Ghz-2.480Ghz ≥95dB ≤0.1% USB充电 50天（理论上） 24小时（理论上） 95g 33.4*27.5*124mm 4、根据蓝牙设备与BX-4的配对的步骤连接蓝牙设备。 STEREO-LINK 蓝灯快闪 一个红蓝灯交替 闪烁，一个蓝灯 慢闪 FCC Statement This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)This device may not cause harmful interference, and (2)this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
