Description

The QTX RCA phono socket to 6.3mm mono jack plug adaptor converts an RCA phono output to a 6.3mm (1/4-inch) mono jack input, allowing connection between consumer audio equipment with phono outputs and professional or semi-professional equipment with jack inputs. The adaptor is passive, requiring no power, and handles unbalanced mono audio signals only.

Designed for patching CD players, mixers, and media players with RCA outputs into PA amplifiers, guitar amps, or mixing consoles with 6.3mm jack inputs, the adaptor suits installations where a short inline conversion is needed without running a full cable. The metal shell and nickel-plated contacts provide a secure connection that resists corrosion and maintains signal integrity over repeated plug/unplug cycles.

The adaptor passes the left or right channel of a stereo RCA source as a mono signal when connected to a single phono output. For stereo-to-mono summing or stereo pass-through, two adaptors are required. The compact inline design adds minimal length to the signal path, making it suitable for tight equipment racks and back-of-console patching where space is limited.

Diameter 6.3
Type 6.3mm (1/4 Inch Jack)
Frequently Asked

Does this adaptor work with stereo signals?

No. The adaptor carries a mono signal only. If you connect it to one side of a stereo RCA output, it will pass that channel as mono. To handle stereo audio, you need two of these adaptors, one for left and one for right.

Is the connection balanced or unbalanced?

Unbalanced. Both RCA phono and 6.3mm mono jack connections are unbalanced by design, so this adaptor does not provide balanced audio or noise rejection over long cable runs.

Can this be used in reverse, from jack to phono?

Yes. The adaptor is passive and bidirectional, so it can convert a 6.3mm mono jack output into an RCA phono input. Signal flow is determined by which end you plug into the source.

What equipment is this suited for?

This adaptor suits patching consumer audio sources (CD players, media players, turntables with phono outputs) into semi-professional or professional equipment with 6.3mm jack inputs, such as PA amplifiers, mixing consoles, or guitar amplifiers configured for line-level input.
