AudioControl AC Studio ACSI420 — 20 ft 4-Channel Double-Shielded Twisted-Pair RCA Interconnect

AudioControl AC Studio ACSI420 — 20 ft 4-Channel Double-Shielded Twisted-Pair RCA Interconnect

The ACSI420 is a 20-foot 4-channel RCA interconnect from AudioControl's AC Studio line. It carries line-level audio signal between components and is built to keep that signal clean over its length.

Key Design Features

AC Studio interconnects use AudioControl's SolidPath cable architecture and PureFlow finely stranded OFC conductors. The TripleTwist layout twists signal, return and drain conductors together to reject interference, and the DualMesh shield adds a second barrier of EMI-rejecting foil and woven mesh. Connectors use a precision-cut Lockgrip 6-point RCA shell for a secure fit.

System Application

A 4-channel run carries front and rear (or front and subwoofer) signal pairs in a single cable, keeping the routing to the amplifier location clean. A 20-foot length is typical for runs from the dash to an amplifier under a seat or in the cargo area.

Installation Considerations

Route RCA cables away from power wire wherever possible, crossing it at right angles where they must meet, to minimize induced noise. Measure the actual routing path, including trim and seat-track clearance, before choosing a length.

Specifications

HF Audio Labs Perspective

AC Studio interconnects are the choice where noise rejection matters most: long runs, high-gain amplifiers, or routing near power wiring. The double shield and 6-point connectors are the practical difference from the EPIC line.
