Description

The QTX 6.3mm mono jack plug to RCA socket adaptor converts a 6.35mm (quarter-inch) mono jack plug connection into an RCA phono socket, allowing unbalanced mono audio signals to pass between consumer and professional equipment. The jack plug terminates in a single-conductor mono configuration, while the RCA socket accepts a standard phono plug from CD players, cassette decks, DJ mixers and similar RCA-output devices.

Commonly used in studios and live sound setups where RCA-output sources need to feed into mixers, amplifiers or recording interfaces with jack inputs, the adaptor eliminates the need for separate conversion cables. The compact in-line design adds minimal projection to the connection point, making it suitable for tight rear-panel installations or crowded patch bays. The metal body provides mechanical strength and helps screen the connection from RF interference in dense equipment racks.

The 6.3mm jack plug and RCA socket are both nickel-plated for corrosion resistance and consistent contact. The mono configuration means the adaptor carries a single audio channel rather than stereo, so it's used for instrument outputs, mono effects sends, or summing stereo-to-mono where appropriate. The adaptor weighs approximately 10g and measures around 40mm from plug tip to socket rear, allowing it to be left permanently connected to frequently-used cables without adding significant bulk.

Frequently Asked

Is this adaptor mono or stereo?

This is a mono adaptor. It carries a single audio channel through the 6.3mm jack plug tip and RCA socket centre pin. It does not carry stereo signals and should not be used where left and right channels need to be preserved separately.

What equipment is this typically used with?

Common uses include connecting RCA-output sources like CD players, tape decks or DJ equipment to mixers and amplifiers with 6.3mm jack inputs, or adapting mono instrument cables to interface with RCA-based recording devices.

Does it work with balanced signals?

No. This is an unbalanced mono adaptor. Balanced signals require a TRS (tip-ring-sleeve) jack and different wiring. Using this adaptor in a balanced signal path will result in signal loss or incorrect operation.

Can I use this to convert stereo RCA to a single jack?

Physically yes, but it will only pass one channel of the stereo signal. If you need to preserve both left and right channels, you need either two mono adaptors (one per channel) or a dedicated stereo RCA-to-dual-jack solution.
