Headphone amplifier driven by a single battery
The HDA-5520mk2 has a current output and allows more precise playback by driving the headphones. This headphone amplifier allows you to experience the true power of headphones.
It will be the successor to the early model HDA-5520 which was popular overseas. By greatly upgrading the internal circuit than the first HDA-5520, it has evolved into a clearer and deeper sound.
Close-closed headphones and earphones are close to the driving method, which is said to be elasticity control, and it is possible to obtain the advantage of lower distortion when the impedance change is small and current drive, and less susceptible to the cable, and the amount of information that is regenerated because it is driven by direct current. However, in open headphones, it becomes close to speaker drive, and impedance change may be large, so use voltage drive in that case.
Because it becomes a battery power supply, there is no trouble with power supply noise. It can operate for about 40 hours with 12 batteries.
