A35.8 Eight Channel Amplifier User Guide

  • Contents

    • Additional information

    These instructions help you get the best possible sound from your A35.8.

    Phase

    The phase of the AC supply can make a significant difference to the sound.

    Use the Polarity Pen supplied with the A35.8 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 right-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

    The RS232 input allows you to connect the A35.8 to a controller system. Use a twisted (null modem) cable. For more information contact Primare at Primare at info@primare.net or visit www.primare.net.

    Trigger

    For convenience the A35.8 can be powered on and off via a remote link cable, avoiding the need to switch it on or off separately from the preamplifier in the system. 

    To power the A35.8 on and off remotely from a Primare processor or preamplifier connect the TRIG OUT signal from the processor/preamplifier to the TRIG IN socket on the A35.8, using a mono 3.5mm jack plug.

    The TRIG OUT socket can be used to daisy-chain the remote output to further A35 series amplifiers.

    Automatic standby

    By default, if no signal is present for 20 minutes the A35.8 will automatically go into standby to save power.

    To disable automatic standby

    • Press and hold down the front panel button for a few seconds, and release once the indicator light has flashed two times and become steadily illuminated.

    To re-enable automatic standby

    • Turn the A35.8 off and then on again using the switch on the back panel.

    Condition Indicators

    Eight internal red clipping indicators, one for each channel, are visible when looking from above into the amplifier through the top cover openings

    When the A35.8 is turned on, or comes out of standby, the clipping indicators will flash briefly.

    The indicators will also flash if the input or output level is too high, and will remain on if that level is constant.

    If clipping occurs repeatedly on a channel reduce the input level on that channel, or increase the headroom on that channel by using a bridged connection to the loudspeaker.

    Additionally, an eight LED warning system is located under the top cover at the front of the amp that will indicate the following:

    • On – DC is detected on the related amp module
    • Flashing – overheating on the related amp module
    • All lights cycling – power supply unit overheating
