AudioQuest Tower Interconnect Cable - 3.5mm to RCA

Tower Is the Long-Grain Copper Entry Point to AudioQuest's 3.5mm-to-RCA Cables

A 3.5mm-to-RCA interconnect lets a source built around a small headphone-style jack — a phone, portable player, or compact streamer — feed a stereo system's RCA inputs directly, with no separate adapter in the signal path. What separates a premium cable from a bargain one is conductor quality and shielding against outside noise.

AudioQuest's Tower is the entry model in its 3.5mm-to-RCA range, with a solid Long-Grain Copper conductor, Foamed-Polyethylene insulation and Direction-Controlled Conductors. Evergreen is the next step up in price.

Solid Long-Grain Copper Conductors

AudioQuest says solid conductors avoid the strand-to-strand contact that causes dynamic distortion, and that Long-Grain Copper has fewer oxides, impurities and grain boundaries than ordinary high-purity copper, for a smoother, clearer sound at both ends of the cable.

Direction-Controlled Conductors

AudioQuest's Direction-Controlled Conductors control the directional grain structure of the wire so induced noise drains away from the circuits it would otherwise disturb. Tower pairs this with Foamed-Polyethylene insulation, the same insulation used on Evergreen, one step up, for an open, low-loss signal path.

The Connectors, Explained

Tower ends in a 3.5mm mini plug on the source side and a stereo pair of RCA plugs on the amplifier side, both cold-welded and gold-plated rather than soldered, the same solder-free termination method used across this AudioQuest range. The jacket is Black with White Stripes PVC.

Who Is This Interconnect Best For?

• You want solid Long-Grain Copper at the lowest price in the range — Tower is the entry model, and Evergreen is there if you later want to step up
• Your source has only a 3.5mm output and your amplifier only takes RCA — Tower bridges that mismatch with no separate adapter
• You want AudioQuest's direction-controlled conductor construction — Tower has it from the entry point of the range
• You are connecting a portable source to a desktop amplifier or powered speakers — this is the short, single-ended run Tower is built for
• You want a little more from the same construction family — AudioQuest Evergreen is the next step up in price in the same 3.5mm-to-RCA line

How Does It Connect to Your System?

Plug the 3.5mm end into your source's headphone or line-out jack, and the two RCA plugs into the matching RCA inputs on your amplifier or receiver, matching red to red and white/black to white/black.

Then power up the system as usual.

Pairs Well With

A 3.5mm-to-RCA interconnect is one link between a source and an amplifier or receiver. It usually joins these categories.

• Music Streamers — many portable and desktop streamers use a 3.5mm output
• Headphone Amplifiers — a common source for a 3.5mm line-level feed
• Digital-to-Analog Converters — some compact DACs use a 3.5mm output instead of RCA
• Stereo Amplifiers — the usual destination for the RCA end of this cable

Frequently Asked Questions

Why does this cable have a 3.5mm plug on one end and RCA plugs on the other?

Many portable players, phones, and compact streaming devices only offer a single 3.5mm headphone-style output, while most home amplifiers and receivers expect a stereo pair of RCA inputs; this cable bridges that one mismatch without an extra adapter.

Does direction matter when I connect this cable?

AudioQuest controls the directional grain structure of its conductors so induced noise drains away from the circuits it would otherwise disturb; where AudioQuest marks a direction on the cable, connect it running from source toward amplifier as marked.

How does Tower differ from Evergreen?

Both share the same Long-Grain Copper, Foamed-Polyethylene insulation and Direction-Controlled Conductors; Tower is the lower-priced entry model in AudioQuest's 3.5mm-to-RCA range, with a Black with White Stripes PVC jacket, while Evergreen steps up in price with a Green/Black Braid jacket.

Is there a step up?

AudioQuest Evergreen is the next rung. It keeps the same Solid Long-Grain Copper conductors and adds a Green/Black Braid jacket.
