The Portal is an active signal mixer that offers two operational modes: parallel and series. In parallel mode, it features two send/return loops along with a main output, allowing you to blend three independent inputs or function as an active ABY switch.
In series mode, the A and B channels operate in sequence, with an A/B switch that enables bypassing either channel. When all three switches are engaged, the mixer provides true bypass functionality, ensuring a clean signal path when not in use.
