Satri Circuit Laboratory VHA-5240C Earphone Amplifier

VHA-5240C is an earphone amplifier featuring the VHA-5240 series developed for VR goggles only for music listening.

The VHA-5240 series was developed to minimize time delay with the goal of accurately and precisely reproducing surround sound used in VR. The case is made of conductive carbon mixed filament to prevent inductive noise. The small size and light weight make it an earphone/headphone amplifier that can be easily carried in a bag or pocket.

It can be connected to the earphone output terminals on smartphones and tablets, as well as to the line output on CD players and video players.

Realistic sound without distortion

The VHA-5240C precisely controls the bias current to maximize the amount of information and accuracy. Furthermore, by widening the bandwidth and using a no-feedback circuit that does not apply negative feedback, transient distortions such as TIM distortion are eliminated and time delays are minimized to the limit, thereby eliminating phase distortion and accurately representing the localization of stereo sound.
