Our brand name, “GRESIM”, was formed from the starting letters of
each of the words in the phrase “GREat Sound IMprovement”.
We design a superior time of life by providing a stable supply of
profound and comfortable sound.
Want to experience a world of deep and elegant sound?
GRESIM promises to be the ultimate partner to help you spend
your time in true bliss.
Active audio board
This board can help draw the best performances
from your audio equipment in everything from low to high tone ranges.
- W600mm × D500mm
- Product main body weight
- Maximum load weight
Our vibration control technologies shutout all extraneous vibrations that can disrupt sound.
Enjoy rich audio that let you faithfully reproduce the original sounds.
This is an active audio board of the highest quality, far beyond the performance of insulators.
Our “HIBIKI” active audio board was born as the result of our proven track record and the vibration control technologies we have cultivated over many years in the nanotechnology field. You can experience the benefits yourself by just placing your audio device on top of the HIBIKI active audio board and carrying out some simple operations. The refined, high nano-level vibration control functions can provide the maximum audio improvement benefits.
Features of HIBIKI active audio board
with 6 degrees of freedom
- Control vibration in every possible direction of the 3 translation and 3 rotation directions.
The HIBIKI active audio board’s superior vibration control functions which can stably maintain the playback conditions of audio equipment make it possible to achieve audio improvement benefits.
- The HIBIKI active audio board makes it possible to auto-level load-bearing surface with 1 button, and to lock the load-bearing surface with 1 button when changing layouts or moving devices.
- Gain is automatically output based on the load weight.
Audio improvement benefits and mechanisms
When no control is applied, disruptive vibration from floors and other sources can be transmitted to audio equipment, causing the equipment’s natural vibration frequency to peak.
Applying control reduces equipment vibration to lower than the disruptive vibration from floors and other sources in all ranges, making it possible to achieve superior performance in all frequencies.
Vibration transmission ratio
Vibration control improves needle sound groove tracing precision.
Improvement of needle sound groove tracing precision in turn improves audio signal reproduction.

The unnatural peak sections marked as “*1” in the graph will be heard as noise.
The fine horizontal lines marked as “*2” in the color map are noise.
You can see that when not using the HIBIKI active audio board, noise like that in the sections marked *1 and *2 will occur, however when using the HIBIKI active audio board noise is reduced.
The HIBIKI active audio board’s nano-level vibration control reduces disruptive vibration and also reduces vibration transmitted to equipment and equipment parts, enabling accurate tracing of records and other audio sources. As a result, noise is reduced and sound quality is improved.
