DI Boxes

Signal Processing -> DI Boxes

DI boxes, also known as direct injection or direct boxes, convert unbalanced, high-impedance instrument or line sources into a balanced lo-Z format for direct connection to a balanced input such as a mixing console's mic input. This, plus the fact that balanced signals easily travel longer cable runs, makes DI boxes indispensible pieces of gear.
We carry a large range from entry-level Behringer models to the much sought-after models from Radial Engineering and Klark Teknik. Active or passive models, Jensen-equipped or other transformer-balanced isolators, we have them all.

AVLFX / Loud Technologies Asia is the official Radial Engineering, Klark Teknik and Behringer distributor and authorised service centre for Singapore.
