Audio cable Hosa CMP-103 — 0.91 m, 6.35 mm TS (male) to 3.5 mm TRS (male), OFC, black

Hosa CMP-103 is a 0.91 m audio cable that links devices with a 6.35 mm TS (male) connector to equipment using a 3.5 mm TRS (male) jack. The cable uses oxygen-free copper (OFC) conductors and nickel-plated connector contacts to provide reliable signal transfer. It is built to accommodate connections between instruments, mixers, headphones and portable players where a change in plug size or an unbalanced-to-balanced interface is needed.

Advantages

The cable’s oxygen-free copper conductors reduce signal loss and preserve audio clarity across the 0.91 m length. Nickel-plated contacts resist corrosion and ensure stable physical and electrical connection. The differing connector types — 6.35 mm TS to 3.5 mm TRS — allow compatibility between full-size instrument outputs and smaller consumer or headphone jacks without adapters. The cable’s construction balances flexibility with durability for regular handling in studio and live situations.

Suitable for

• Connecting electric guitars, basses or keyboards to amplifiers or mixers with a smaller input
• Adapting headphone outputs or portable players to larger 6.35 mm inputs
• Linking stage or studio equipment where a size-adapter cable eliminates the need for separate adapters
• Temporary signal routing between balanced TRS-equipped devices and unbalanced TS outputs (note: wiring remains unbalanced from the TS end)

Key specifications

• Cable length: 0.91 m
• Connector A: 6.35 mm TS, male
• Connector B: 3.5 mm TRS, male
• Conductor material: oxygen-free copper (OFC)
• Connector contact plating: nickel
• Color: black

How to use

Insert the 6.35 mm TS male plug into the instrument or amplifier output designed for a 6.35 mm jack. Insert the 3.5 mm TRS male plug into the smaller input or headphone jack of the target device. Ensure both devices are powered down or volume levels are low when connecting to avoid loud transients. Verify signal flow and adjust levels on the source and destination equipment for proper gain staging. Note that when connecting a TS output to a TRS input, the connection is effectively unbalanced and may be susceptible to interference on longer runs.

Usage recommendations

For best performance, use the Hosa CMP-103 for short runs (such as instrument-to-amp or portable-to-desk connections) where the 0.91 m length and unbalanced wiring are appropriate. Avoid running the cable parallel to power lines or near high-interference equipment. If a balanced connection over longer distances is required, consider using a true balanced cable or a direct box to maintain signal integrity.
