Overview

The Mogami Gold Key S-15R is a 15-foot unbalanced stereo cable purpose-built for connecting stereo keyboards and instruments to mixers, audio interfaces, or amplifiers. It uses a single 1/4" TRS connector on the keyboard end that splits into two 1/4" TS right-angled connectors on the output end, carrying the left and right stereo channels independently. The cable is constructed around Mogami's dual-conductor 75-ohm coaxial design with oxygen-free copper cores, which is engineered to preserve the full frequency range and dynamic detail of your keyboard's output without introducing coloration or signal degradation.

Each connector features gold-plated contacts for corrosion resistance and long-term connection reliability, while ultra high density spiral shielding along the cable's length provides effective rejection of electromagnetic and radio frequency interference. The right-angled TS plugs on the output end reduce strain and keep a low profile when connected to rack gear or tightly spaced inputs. At 15 feet, the cable offers enough reach for most stage and studio configurations, making it a practical choice for keyboardists who need a dependable stereo connection with minimal signal compromise.

Pros & Cons

👍 Pros

  • Oxygen-free copper conductors preserve signal clarity and reduce resistance-related tone loss
  • Ultra high density spiral shielding provides strong rejection of electromagnetic and radio frequency interference
  • Gold-contact connectors resist corrosion and maintain reliable connections over time
  • 15-foot length offers practical reach from keyboard to mixer or audio interface on most stages and studios

👎 Cons

  • TRS-to-dual-TS configuration is specific to stereo keyboard setups and not usable as a standard mono instrument cable
  • 15-foot length may be more than needed for compact home studio setups, adding unnecessary cable bulk
  • Higher price point compared to generic keyboard cables, which may not be justified for casual or practice use
  • Unbalanced design means it is more susceptible to noise on very long runs compared to a balanced connection

Frequently Asked Questions

One end has a single 1/4" TRS (stereo) plug, and the other end splits into two 1/4" TS (mono) right-angled plugs. The TRS end connects to your keyboard's stereo output, and the dual TS ends connect to a mixer, audio interface, or amp inputs.
This is an unbalanced stereo cable. It carries the left and right channels of a stereo keyboard output via separate conductors, but it is not a balanced audio connection.
The right-angled TS plugs reduce strain on the connectors when plugged into rack-mounted gear or tight spaces, and they keep the cable close to the equipment to minimise snagging.
The Gold Key S-15R uses Mogami's proprietary 75-ohm coaxial construction with oxygen-free copper cores and ultra high density spiral shielding, which is designed to minimise signal loss, interference, and noise over the 15-foot run.
