These instructions help you get the best possible sound from your PRE35.
The phase of the AC supply can make a significant difference to the sound.
Use the Polarity Pen supplied with the PRE35 to verify which pin is live on your AC power cable.
Ensure that the live pin of the AC power cable is connected to the left-hand pin of the power connector, viewed from the back panel:
Your Primare will start to sound best after an initial burn-in of approximately 24 hours.
You will notice a further smaller improvement in sound quality for at least another 3 days’ playing.
