If the voltage on the back of my TubePRE does not match the voltage listed on the power supply what do I do?
The voltage on the TubePRE’s external power supply may change. If the power supply came factory sealed with the unit, then it is the right power supply. If the power supply did not come with the unit it is recommended that it not be used. If your power supply is damaged or missing, please consult your salesperson or call Presonus.
Can I use a higher/lower/alternate voltage power supply that was not supplied with my TubePRE?
Use of any power supply that was not included with the unit voids the warranty of the TubePRE and may cause damage to the unit or the user. It is strongly recommended that you refer any service issues to Presonus.
Can the TubePRE be rack mounted?
Yes, please consult your local Presonus dealer or www.presonus.com for rack mounting instructions and to locate the appropriate rack mount adaptor.
Can I use a different size/style tube in the TubePRE?
The only tube that can be used in the TubePRE is a 12AX7. Any variation can cause damage to the unit/user and voids the warranty. Please refer to Section 3.5 of this manual for further directions on changing the tube. It is strongly recommended that you refer any service issues to Presonus or check our website at www.presonus.com.
