Crystal mini是一款锂电池供电,机内提升至高电压的便携式耳机放大器,在便携式设备中一般是使用较低的供电电压,而且是非对称或单电源供电,这样的耳机放大器驱动能力有限,Crystal mini使用钰龙韵电子自主开发的高性能超低纹波专用开关电源供电,将锂电的电池电压变换为正负对称的+ -8VDC双电源供给电路使用,ADA4075进行放大,BUF634缓冲输出。
精密设计调校的电路参数,配合高达3000MAH的锂电池,使本机拥有优异的声音表现。强劲的输出功率,足够驱动600R耳机的电压摆幅,和良好的续航能力。(60小时)
警告:本机充电只能使用本机原装充电器进行充电,使用非原装充电器充电可能会导致电池爆炸。
Crystal mini is a portable headphone amplifier which uses the Li-ion as the power supply,in the machine the voltage of Li-ion can be boosted up to high voltage.The portable devices usually use the lower voltage as the power supply and the power supply is either asymmetrical or single,the driving ability of the headphone amplifier is limited.The Crystal mini uses the high efficient switching power supply with lowest ripple to boost the voltage of the Li-ion up to +8V-8V to supply the circuit.The ADA4075 is used to amplify and the BUF634 is used as the buffer output.
With the circuit parameters that is designed and adjusted carefully,and the lithium battery that can reach up to 3000mAH,the Crystal mini can have the best sound performance, the powerful output power and good abilty of duration.
Warning: This machine must be used the original charger to charge, using the non-original charger to charge could cause an explosion!
