AudioQuest Yosemite 90° JIS to RCA Tonearm Cable with Ground Wire

Advanced Tonearm Cable Technology with a Space-Saving 90° JIS Connection

The AudioQuest Yosemite 90° JIS to RCA Tonearm Cable is a premium analog interconnect designed for high-performance turntables that require a right-angle JIS tonearm connection. Featuring Solid Perfect-Surface Copper+ (PSC+) conductors, Carbon-Based Noise-Dissipation, FEP Air-Tube insulation and AudioQuest's 72V Dielectric-Bias System (DBS), Yosemite is engineered to manage distortion and unwanted radio-frequency interference in sensitive vinyl playback systems.

Its defining feature is the 90-degree JIS connector, which accommodates compatible tonearms where a straight connector may be impractical because of limited clearance or cable-routing requirements.

The cable terminates in stereo RCA connectors for connection to a compatible phono preamplifier and includes a separate ground wire. Its green-on-black nylon braided jacket completes the distinctive Yosemite design.

 

90° JIS Connector for Compatible Tonearms

The Yosemite 90° is designed for turntables and tonearms that require a right-angle JIS connection.

Unlike the straight Yosemite JIS to RCA cable, the 90-degree version changes the cable's exit direction at the tonearm. This can be especially useful when a tonearm's output connector is positioned near the turntable plinth, supporting structure or another surface that limits cable clearance.

The right-angle configuration can also make it easier to route the cable without creating an unnecessarily sharp bend immediately after the connector.

Because tonearm connections are not universal, confirm that your turntable requires a 90° JIS connector before ordering. The straight and right-angle versions should not be considered interchangeable without checking the available clearance and connector orientation.

Solid Perfect-Surface Copper+ Conductors

Yosemite uses AudioQuest's Solid Perfect-Surface Copper+ (PSC+) conductors, the company's highest-grade copper conductor material.

AudioQuest developed Perfect-Surface Technology to produce exceptionally smooth, high-purity conductor surfaces. PSC+ is intended to minimize distortion associated with conductor grain boundaries and surface irregularities.

The solid-conductor design also eliminates the electrical and magnetic interaction between individual strands found in conventional stranded cables.

These design considerations are particularly relevant to tonearm cables, which carry the extremely low-level electrical signals generated by phono cartridges.

Yosemite's PSC+ construction is designed to maintain signal integrity while supporting AudioQuest's broader RF Noise-Dissipation strategy.

Carbon-Based Noise-Dissipation

Yosemite incorporates AudioQuest's Carbon-Based Noise-Dissipation system, using three alternating layers of metal and carbon-loaded synthetic materials.

These layers are designed to absorb and reflect unwanted radio-frequency energy before it reaches the shield connected to ground.

Modern listening environments contain numerous potential sources of RF interference, including wireless routers, computers, televisions, mobile devices and switching power supplies.

Because phono cartridge signals require substantial amplification, controlling unwanted interference along the tonearm cable is an important consideration.

AudioQuest's Carbon-Based Noise-Dissipation is designed to reduce the amount of induced RF energy reaching connected audio components.

72V Dielectric-Bias System

One of Yosemite's principal technologies is AudioQuest's 72V Dielectric-Bias System (DBS).

Cable insulation behaves as a dielectric, meaning it can store and release electrical energy. AudioQuest developed DBS to establish a consistent electrostatic field within the insulation.

According to AudioQuest, maintaining this polarization minimizes dielectric-related noise and improves the cable's ability to dissipate induced RF interference.

The 72V DBS works alongside Yosemite's conductor and insulation technologies as part of its overall noise-management design.

FEP Air-Tube Insulation

Yosemite features FEP Air-Tube insulation around its positive conductors.

Air has exceptionally low dielectric absorption, making it desirable for minimizing interaction between a conductor and its surrounding insulation.

AudioQuest's Air-Tube construction reduces physical contact between the positive conductors and the FEP insulation. The negative conductors use a deliberately different insulation arrangement suited to their electrical function.

This approach is intended to reduce insulation-related interference and preserve dynamic contrasts.

Direction-Controlled Conductors

All internal conductors in Yosemite are Direction-Controlled.

AudioQuest identifies a directional grain structure created during the metal-drawing process and controls conductor orientation as part of its RF Noise-Dissipation strategy.

This construction is designed to manage how induced RF energy travels through the cable.

Where directional arrows are present on the connectors, follow the manufacturer's indicated installation direction.

Cold-Welded, Direct-Silver Plated Pure Red Copper Terminations

Yosemite features cold-welded, Direct-Silver Plated Pure Red Copper terminations.

AudioQuest's high-pressure cold-welding process creates a conductor-to-connector connection without conventional solder. Direct silver plating is applied without an underlying nickel layer.

These terminations complement Yosemite's PSC+ conductors and advanced noise-management construction.

Integrated Ground Wire for Vinyl Playback

Yosemite 90° includes a separate ground wire for compatible turntable and phono preamplifier connections.

Many turntables use a dedicated grounding connection alongside the stereo audio cables. Establishing the appropriate ground connection can help prevent certain types of hum and interference.

Yosemite combines the stereo tonearm connection and ground wire into a purpose-built cable assembly.

Grounding requirements vary between turntables and phono stages, and a replacement cable cannot correct every electrical noise or ground-loop problem.

Where to Use AudioQuest Yosemite 90°

Yosemite 90° is designed for compatible high-performance turntables and tonearms that require a right-angle JIS connection.

Typical applications include replacing an existing 90° JIS tonearm cable, connecting a compatible tonearm to an external moving-magnet or moving-coil phono preamplifier, or completing an analog system where the tonearm's connector position makes a straight cable impractical.

Its dedicated ground wire allows the grounding connection to be routed alongside the stereo audio cables.

Before selecting Yosemite 90°, verify your tonearm's connector type, required connector orientation and the input configuration of your phono preamplifier.
