Description

Overview

An in-line adapter that steps a 2.5 mm male plug up to a 3.5 mm female jack, joining small-jack gear to standard auxiliary cabling. Models run CR-099 to CR-106 plus CR-134.

Specifications

  • Plug end: 2.5 mm male
  • Jack end: 3.5 mm female
  • Direction: 2.5 mm source to 3.5 mm cable
  • Form: short in-line body
  • Models: CR-099, CR-100, CR-101, CR-102, CR-103, CR-104, CR-105, CR-106, CR-134

Purpose

Equipment with a 2.5 mm output, such as headsets, compact speakers and radios, will not seat in a 3.5 mm socket, and cutting the plug off is a permanent fix to a temporary problem.

Applications

  • 2.5 mm headset into a 3.5 mm source
  • Portable speaker auxiliary input
  • Radio and intercom earpieces
  • Car auxiliary socket for a small-jack device

How to Use

  1. Measure both if the markings are worn; one millimetre is easy to misjudge.
  2. Confirm direction: this presents a 2.5 mm male plug, so the source must be a 2.5 mm jack.
  3. Seat the plug fully, then test at low volume before raising the amplifier.
  4. Expect diameter change only: it adds no contacts, so mono stays mono.
  5. Caution: no rating is published, so line-level audio only, never mains or an amplified output.
