Description
Audac ALI20MK2 Audio Line IsolatorThe ALI20 25 are audio line isolators designed to isolate audio devices from each other. In most cases, they are used to avoid hum caused by ground loops in audio systems. They offer a complete passive solution for the isolation of a stereo balanced audio signal. It features dual XLR in and output connectors and a ground lift switch. The in and output phase are matching. The ALI20 25 are both built with an audio transformer that has a turns ratio of
The ALI20/25 are audio line isolators designed to isolate audio devices from each other. In most cases, they are used to avoid hum caused by ground loops in audio systems. They offer a complete passive solution for the isolation of a stereo balanced audio signal. It features dual XLR in- and output connectors and a ground lift switch. The in- and output phase are matching. The ALI20/25 are both built with an audio transformer that has a turns ratio of 1:1 and an impedance of 600 Ohm. The difference is the shielding of the transformer. The ALI20 contains a shielded transformer which complies with the requirements of most standard applications, while the ALI25 contains a MU-metal shielded transformer which can be used when regular shielding becomes inadequate. This ensures the best results in even the highest EMI polluted environments.
