【Version Upgrade Details】

1. change gain
Change from conventional 10.5 dB to 4.5 dB. Gain is reduced by 6dB (gain is halved) and white noise is reduced.
Low-impedance, high-efficiency earphones are increasing in the market, and the gain has been optimized to meet their needs in terms of being a portable amplifier.
After the gain change, we have confirmed that headphones with a few hundred ohms can be sufficiently loud for today's players that can handle high output.

2. firmware update
Includes volume curve changes and other minor modifications.
In changing the volume curve, the adjustment range for the low volume range has been expanded. The maximum volume remains unchanged.
See below for detailed descriptions before and after the volume curve change.
