仕上げと外観

The cable jacket is printed using environmentally friendly, water-based ink. As a characteristic of this sustainable process, minor printing imperfections (such as slight blurring or ink bleeding) may occasionally be present. It is important to note that these cosmetic variations do not affect the electrical performance or integrity​ of the cable. Gotham does not consider such minor aesthetic inconsistencies to be product defects.

Gotham Cables のブランドの歩み

Since its founding in 1976, Gotham has been dedicated to the engineering of professional-grade audio cables. The brand's core philosophy is rooted in "technical correctness,"​ prioritizing signal integrity above all else. This commitment is exemplified by their renowned double-shielding technology, a design principle with origins in German broadcast engineering traditions. This legacy of quality and reliability has led to Gotham cables being the trusted choice for numerous renowned microphone manufacturers and professional studios worldwide.

精密な製造工程

To ensure the highest quality and preserve the designed performance, each cable is meticulously hand-assembled by authorized distributors (such as the reputable Tiger Fu Audio Studio). The critical soldering process is performed using precision tools like JBC constant-temperature soldering stations. This controlled approach to soldering guarantees flawless, reliable connections that maintain the signal path's purity and ensure consistent, high-quality sound.

用途

Engineered for critical applications, this cable is ideally suited for:

• プロ用レコーディングスタジオ：​ 信号品質が重要となる環境。
  
• ハイエンドオーディオシステム：​ ソースからアンプまで高い再現性が求められるシステム。
  
• 長距離のマイク配線：​ Its superior shielding effectively rejects RF/EMI interference over extended lengths.
  
• 高い耐ノイズ性と最小限の信号損失が求められる用途。
