1. General

The flashlink DAC-PAL-M is a high-quality SD distribution amplifier with 3 x SD digital and 3 x
composite analogue outputs. The SDI outputs are compliant to SMPTE 259M, and the composite
analogue outputs are PAL / PAL-M compatible.

DAC-PAL-M user monitoring can be performed via the GYDA control interface.
The DAC-PAL-M is designed for all distribution and monitoring purposes in studio, duplication and

Broadcast applications.
