The Morley ABY Pro combines top-shelf quality with dead-simple operation. It can be employed in multiple situations. Use it to route one signal to two outputs, then select between them or combine them. The ABY Pro includes a custom Ebtech 1:1 isolation transformer for absolute transparency and level output, along with silent switching to minimize pops and bleed. Beyond that, you get a reverse polarity switch to resolve phasing issues and a ground-lift switch to combat hum. If A/B/Y boxes give you a headache, give Morley’s ABY Pro a try — it’s just what the doctor ordered.
