About the Zapco ST-BR
From our tech experts at CEN
The Zapco ST-BR is a remote level control for Zapco Studio Series amplifiers, allowing you to adjust output volume from under the dash. It features a solid housing for a neat, secure mounting and is compatible with the ST-6X SQ III, all ST-XM III mono amplifiers, the ST-5B and the ST-1B.
Who it suits
The ST-BR suits anyone running a compatible Zapco Studio Series amplifier who wants a tidy, accessible level control within easy reach. It is a useful addition to a system built around the ST-5B or the ST-1B, as neither includes one in the box.
Our tech experts advise
All ST-XM III mono amplifiers already include an ST-BR in the box, so check before ordering. For the ST-5B and ST-1B, this is a separate purchase. Fitting the control under the dash involves routing the cable neatly; if you need help with installation, pricing varies per vehicle — see our car audio installation page.
