Stereo jack cable Procab 1KPCL020 — 3 m, male 3.5 mm to 3.5 mm

Procab 1KPCL020 is a 3 m stereo jack cable with male 3.5 mm connectors on both ends, designed to transmit stereo analog audio between portable devices and line-level inputs. The cable carries separate left and right channels to preserve stereo imaging and is intended for straightforward connections between smartphones, tablets, laptops, portable music players, car stereos and active speakers. With a three-meter length it provides extra reach for home, studio or mobile setups where an unbalanced analog connection is required.

Advantages

The cable offers a standard 3.5 mm TRS connection at both ends for wide compatibility with consumer and professional equipment that accepts stereo mini-jack inputs. Its 3 m length reduces the need for extensions while keeping signal loss and noise to a minimum in typical line-level use. The balanced construction of the connectors and consistent shielding help maintain clear left and right channel separation and reliable physical contact during repeated insertion and removal.

Suitable for

• Connecting smartphones or tablets to car stereos and portable speakers
• Linking laptops or MP3 players to active monitors or home audio systems
• Temporary studio patching where a short analog stereo connection is needed
• Use in presentations or meetings to feed audio from a laptop to room sound systems

Key specifications

• Cable length: 3 m
• Connector type: 3.5 mm male to 3.5 mm male (TRS stereo)
• Channel configuration: stereo, left and right channels
• Intended signal level: unbalanced analog line-level and headphone outputs
• Typical applications: portable audio devices, laptops, car audio, active speakers

How to use

Insert one 3.5 mm male connector into the headphone or line-out jack of the source device and insert the other connector into the line-in or auxiliary input of the destination device. Ensure both connectors are fully seated to avoid channel dropouts or mechanical noise. For best performance, route the cable away from power supplies or mains cabling and avoid sharp bends near the connectors. When disconnecting, pull the connector body rather than the cable to prevent strain on the termination.

Usage recommendations

Use the cable at line-level or headphone outputs and avoid exposing it to excessive tension, moisture or heat. If longer runs are necessary, consider a higher-gauge cable or an alternative connection type to maintain signal integrity over distance.
