[Case Study] ANTIKNOCK

[Case Study] ANTIKNOCK

Especially matches situations where a powerful high is needed! An example that also contributed to the improvement of vocal clarity.

We would like to introduce a case where Martin Audio's 'TORUS' was installed at the long-established live house "ANTIKNOCK" in Shinjuku. The existing speakers were very large and designed for medium to long distances, which made the stage appear smaller. Additionally, there were concerns about the resolution of the bass during live performances. The solution was to introduce a simple combination of two main speakers from the series, the "T1215," and two subwoofers, the "SXCF118," on each side. The height of the setup was meticulously calculated, resulting in a configuration that was optimal in terms of both sound quality and size. [Case Overview] ■ Installation Location: Long-established live house "ANTIKNOCK" in Shinjuku ■ Installed Products: Martin Audio TORUS T1215, SXCF118, iKON iK42 *For more details, please refer to the related links or feel free to contact us.

Authorized retailer 'GPA-680DU/GPA-680D2'

Authorized retailer 'GPA-680DU/GPA-680D2'

Compact speaker weighing about 3kg in A4 size! Certified with the technical standards mark.

Due to the 2.4GHz band, we have implemented measures to prevent information leakage. This is an active speaker with a built-in amplifier that does not require wiring. *Note: If there is interference from products in the same band, such as Wi-Fi, televisions, microwaves, cordless phones, or Bluetooth devices, the wireless microphone may not produce sound. This is not a malfunction and is not covered by warranty. It is also possible to output simultaneously wirelessly to other companies' audio equipment (existing facility audio, microphone connection issues, or speakers that can no longer use audio functions). Of course, simultaneous operation with OKAYO (GPA series, JL series, JDL series) is also possible. This product complies with the technical standards certification stipulated by the Radio Law. Using devices without the technical conformity mark may violate the Radio Law, so please be cautious about purchasing unapproved devices or using equipment that complies with the old spurious emission standards. Sales Start: GPA-680 (2.4GHz band) from July 2016 GPA-670 (800MHz analog band) from May 2019 - discontinued JL-A500 (800MHz analog band) from September 2020 JDL-510 (800MHz digital band) from April 2022

Mutracks

Mutracks

No speaker wiring is needed. It's a new technology that transmits music via wireless LAN.

"Mutrax" is a technology that wirelessly distributes music from a single source to multiple speakers. Since all music data is processed as digital data, it is possible to freely control the volume, sound quality, and delay of each speaker. As there is no longer a need for audio cables connecting the source and speakers, it allows for a flexible and safe layout when building audio systems in stores or event venues. [Features] - Individual settings for volume, sound quality, and delay - Capable of playing multi-channel audio sources *For more details, please download the PDF or feel free to contact us.

[Example] Speaker structure verification confirmation water jet cutting

[Example] Speaker structure verification confirmation water jet cutting

Simultaneous cutting of all materials such as metal, resin, fiber, and adhesive.

A cost-effective car speaker that incorporates high-performance carbon fiber in the diaphragm. The request was for a complete equal division with center cuts, but due to concerns about the retention rate of each part after cutting, a 90-degree opening cut was proposed. The separated side retained almost its original shape except for the cutting width (cut allowance, kerf width). However, even with the insertion of special stabilizing materials in the frame (unstable areas) and the magnet section to fill the gaps, there was still some impact on the interlayer and cutting surface near the cutting width (cut allowance, kerf width) due to the state of jet water flow diffusion after penetrating through the layers, resulting in a lack of clarity and a completely vertical surface.
