Datavideo DAC-80 2-Channel Audio Isolation Transformer

The Datavideo DAC‑80 is a passive, two-channel audio isolation transformer designed to remove hum caused by ground loops between connected audio equipment. Place it in the signal path using its two XLR inputs and two XLR outputs: it breaks the inter-equipment ground path while preserving the audio signal with low insertion loss and distortion. The DAC‑80 requires no power. The optional RMK‑2 rackmount kit can hold up to eight compatible Datavideo converters in a 19-inch rack.

Two-channel audio transformer

Clean audio without ground-loop hum

The passive Datavideo DAC‑80 isolation transformer helps remove hum caused by ground loops between connected audio devices. Its two XLR signal paths break the inter-equipment ground connection while keeping the audio signal transparent with low insertion loss and distortion. No external power is required.

Two signal paths

Two XLR inputs and two XLR outputs isolate both channels of an analogue audio signal in one compact device.

No external power

The passive design needs no power supply or battery; connect the transformer directly in the audio signal path.

Rack integration

The optional RMK‑2 rackmount kit can install up to eight compatible Datavideo converters in a standard 19-inch rack.
