Gashin Strong Bass System

Background
Gashin Strong Bass System was a system that was introduced by Namco in 1997 for their System 23 arcade system board, specifically for their games Time Crisis II and Crisis Zone. It was simply comprised of a bass amplifier that was hooked up to the arcade's sound system, which amplifies the bass frequencies of the speakers.

(December 13, 1997-March 29, 1999, June 20, 2006)
Logo: On a black background, we the see letters "GAS" and "HIN" moving from the left and right corners of the screen. As the letters collide with each other, the screen fades to white, forming the word "GASHIN" (which is surrounded by two white-colored bars). On the bottom of the logo is the text "STRONG BASS SYSTEM."

Technique: Simple 2D computer animation.

Music/Sounds: An impact sound effect can be heard after the the letters "GAS" and "HIN" collide with each other. Music/Sounds Variants:
 * On Crisis Zone, a whooshing sound effect can be heard.
 * On Time Crisis 4, an explosion sound effect is used instead.

Availability: Rare. The logo only appears in the arcade versions of Time Crisis II, Crisis Zone, and Time Crisis 4 after the Namco logo. Note that while the former two arcade games are easy to find (especially Time Crisis 4), the latter one is difficult to find.
