  • Contents

    • Additional information

    These instructions help you get the best possible sound from your PRE35.

    Phase

    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:

    Burn-in

    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.

    RS232 and trigger

    The RS232 input allows you to connect the PRE35 to a controller system. Use a twisted (null modem) cable. For more information contact Primare at info@primare.net or visit www.primare.net.

    The Trigger output allows the PRE35 to switch on other devices, such as a CD32.

    Using the PRE35 with a CD35

    Your PRE35 is an ideal companion to the Primare CD35 CD Transport. For best results link the two products together as follows using the two cables supplied with the PRE35:

    To connect the trigger cable

    The Trigger cable ensures that the CD35 switches on, or to standby, when you operate the  button on the front panel of the PRE35.

    • Connect the Trigger cable from the PRE35 TRIG OUT to the CD35 TRIG IN.

    Error messages

    The following error messages on the front panel display indicate an error condition:

    Clipping has occurred on an input. Decrease the input gain; see Input gain.

    • Power off PRE35 and disconnect the speaker connections.

    If this solves the problem, check the speaker wiring.

    If the problem persists

    • Power off PRE35 and disconnect all input connections.

    If this solves the problem, there is a DC offset on one of the inputs.

    If the problem persists

    • Contact your dealer for service arrangements.

    Factory reset

    Press and hold the standby button on the front panel to display the main firmware version number.
