Shure HPAQA1 Locking 1/4" Adapter for SRH240A, SRH440, SRH550D...
Product Overview
The Shure HPAQA1 1/4-inch threaded headphone adapter converts the 3.5 mm stereo output on Shure SRH-series professional headphones to a locking 1/4-inch (6.35 mm) connection. It is the standard accessory for connecting studio headphones to mixing consoles, headphone amplifiers, and rack-mounted monitoring gear in commercial AV environments. This threaded design prevents accidental disconnection during critical monitoring.
Product Description
The HPAQA1 is a precision-machined 1/4-inch threaded adapter designed to mate with the 3.5 mm stereo mini-plug on the detachable cables supplied with Shure SRH professional headphones. The threaded coupling screws securely onto the headphone cable connector, creating a locked 1/4-inch plug that stays seated in patch bays, console headphone jacks, and amplifier outputs. For AV integrators and facilities managers standardizing on 1/4-inch monitoring infrastructure, this adapter keeps SRH-series headphones compatible with existing equipment without re-terminating cables. It is a low-cost, commercial-grade accessory worth stocking as a spare for any installation that relies on Shure studio headphones. Replacement cables such as the Shure HPASCA2 cable assembly and the Shure HPASCA3 detachable cable pair with the same headphone families.
