Switchcraft 319 Stereo Jack to Balanced, Mono 3-Contact Terminal Block with Pad and Ground Lift Switch, 1/8"

Get reliable, low-noise line-level audio from consumer devices with the Switchcraft AudioStix 319 1/8" stereo jack to balanced, mono 3-contact terminal block. Designed for AV integrators and security professionals, this passive converter takes an unbalanced 3.5mm stereo input and delivers a balanced, mono, line-level output—reducing interference and improving signal integrity for surveillance, monitoring and live sound applications. A built-in isolation transformer protects downstream equipment and, together with the ground-lift switch, resolves ground-loop hum common in security and networked audio systems. The selectable 20 dB pad provides immediate level matching so smartphones, tablets or consumer media players won't overload pro mixers and recorders. Compact and rugged, the red AudioStix enclosure installs individually or rear-mounts into QGPK-Series rack panels for clean, scalable deployments. Ideal for installers working on CCTV audio, paging systems, conference rooms or broadcast monitoring, the Switchcraft 319 streamlines integration between consumer sources and professional audio infrastructure. Add it to your toolkit to eliminate noise, protect equipment and simplify level-matching—order now for secure, stable audio connections.
