Portable full Balance headphone amplifier
BX-2 Instruction
Support unbalance input and output. Caution : Balanced output only support the balanced headphone only.
High definition matched components
ROMH twins transistor ,ON power transisor ,Panasonic CBB audio capacitor ,NEC tantalum capacitor ,VISHAY resistor
Fully supported analog signal amplifier
Supported 3.5 unbalance?2.5 and 4.4 balance signal input. Supported 3.5 unbalance output?2.5 and 4.4 balance headphone output?
CAST full balance current boost up circuit. Mirror high speed buffer operaition amplifer ON-DB139/140 transisor, Low impedance type A serial type volume contorl?audio signal passthrough without carbon volume control?more clear and natural. Amplifier inclucding AI switching.whan 3.5 unbalance singal input will auto convert to full balance singal to keep the high quality output.
