The 1U sized S2-PSU is pin compatible with the original 2U sized S2-PSU power supply, so can be used as a straight like-for-like swap, using the same connection cables. The new units have a great deal of improvements on the original design:

1. Increased power efficiency, so that less power is drawn and therefore less heat generated.

2. An improved over-current and over-voltage protection system to give increased reliability and stability.

3. A quiet internal cooling fan with selectable Fast, Medium, or Slow speeds to reduce noise.

4. A new 1U chassis so it takes up less space in a 19” rack.

Important Notes:

1. Please note that ALL connections to the mixer should be made before powering up the S2-PSU, otherwise this could trigger the over-current protection. If the over-current protection kicks in, then the unit needs to be powered down for approximately a minute to reset the over-current protection.

2. This 1U sized S2-PSU is incompatible with S2-PSUS power supply switcher. Please contact Sonifex for recommended settings to configure the S2-PSUS.
