Audio adapter SpeaKa Professional KKA-635 — 6.35 mm plug to 3.5 mm socket

The SpeaKa Professional KKA-635 audio adapter converts a 6.35 mm (1/4") plug into a 3.5 mm (1/8") socket, allowing headphones, instruments or audio leads with a 3.5 mm plug to be connected to equipment with a 6.35 mm jack. The adapter is compact and intended to provide a simple, space-saving connection solution in studios, rehearsal rooms and consumer audio setups where compatibility between plug sizes is required.

Advantages

The adapter offers a compact metal-bodied solution that occupies minimal space while maintaining a secure mechanical connection between plug sizes. Its straightforward passive design requires no power and introduces no electronic processing, preserving the original audio signal path. The form factor makes it easy to carry in a gig bag or audio kit and to insert into crowded panels without needing extra cables or converters.

Подходит для

• Подключения наушников с 3.5 мм штекером к усилителям, микшерам и другим приборам с 6.35 мм гнездом
• Присоединения инструментальных кабелей и электронных инструментов с мини-джеком
• Использования в студиях, репетиционных помещениях и домашних аудиосистемах
• Временных или постоянных монтажных решений, где требуется смена форм-фактора разъема

Key specifications

• Input: 6.35 mm (1/4") male plug
• Output: 3.5 mm (1/8") female socket
• Design: passive, no electronic components
• Housing: compact metal construction for mechanical durability
• Contact configuration: stereo-compatible TRS connection

How to use

Insert the 6.35 mm male plug of the adapter securely into the device's 6.35 mm jack. Then plug the 3.5 mm connector of the headphone, instrument or cable into the adapter's 3.5 mm socket. Ensure connectors are fully seated to avoid intermittent contact. Remove the adapter by pulling it straight out without excessive twisting to prevent strain on connectors or sockets.

Usage recommendations

Use the adapter for passive, line-level and headphone connections where a mechanical conversion between 6.35 mm and 3.5 mm formats is required. Avoid using the adapter in applications needing balanced TRS to TS conversions or impedance matching without additional equipment. Store the adapter in a dry environment and prevent heavy mechanical force or bending at connector points to maintain reliable contact and prolong service life.
