    Front Panel The S2-PSU is a 2U high rack-mount unit, which can supply power to the entire range of S2 mixers. A lead with a special 9 pin D-Type socket (see Fig 2-9) on each end is used to connect the power supply to the mixer.

  • Page 29: Rear Panel

    The rear panel of the equipment carries the Serial Number of the machine. The operating voltage of the S2 power supply is selectable at the fuse carrier on the power inlet port of the S2-PSU unit. Ensure that the machine operating voltage is correct for your mains power supply.

  • Page 30: Ordering The Correct Mains Lead

    The safety specification of your S2 power supply complies with local requirements and must be earthed through the mains connector. If for any reason, you need to use the S2 with a different power cable, you should use the following wiring guidelines.

The S2-PSUS has been redesigned (from April 2011) to work with both 1U and 2U S2-PSU power supplies, but this is only for S2-PSUS switchers with a serial number higher than 16948. Contact Sonifex if you need to replace a 2U S2-PSU and are using an S2-PSUS power supply switcher - either a new version of the S2-PSUS will be required or a 2U S2-PSU power supply will need to be specifically requested.
