Product Overview

The Williams Sound AC ADP1D-N is a 3.5mm stereo jack to 3.5mm mono plug adapter that allows stereo headphones to connect to devices with mono 3.5mm audio outputs. This adapter is specifically compatible with Williams Sound receivers such as the PPA R35-8 FM receiver and the PKT C1 Pocketalker, bridging the mismatch between stereo headphone connectors and mono output jacks on assistive listening devices. AV integrators and facilities managers supporting hearing-impaired users can use the AC ADP1D-N to allow standard stereo headphone use with mono-output Williams Sound receivers.

Product Description

The AC ADP1D-N adapter converts the stereo TRS jack on headphones to a mono TS plug compatible with the 3.5mm mono output found on various Williams Sound FM receivers and personal amplifiers, including the PPA R35-8 and PKT C1. Without this adapter, connecting stereo headphones to a mono receiver output can result in audio in only one ear, depending on the headphone design and the mono output configuration. With the AC ADP1D-N, both headphone channels receive audio correctly from the mono receiver output. This is a compact, passive adapter requiring no power or batteries, and it stores easily in AV equipment kits or receiver carry cases. AV technicians deploying Williams Sound assistive listening systems where end users prefer stereo headphones should stock this adapter alongside compatible receivers. The adapter carries a 90-day Williams Sound warranty.
