This user guide describes the features and explains how to set up the amplifier for the best sound quality and ease of operation in order to allow for the most enjoyable reproduction of sound from all your sources.
For additional support and assistance please contact your local authorized Primare dealer, or visit our website at www.primare.net.
Your A35.8 is supplied with:
If any of these items are missing please contact your supplier. We recommend you retain the packaging in case you need to transport the unit at a later date.
Note that due to the high current draw, the A35.8 features a C20 IEC socket on the back panel, rather than the usual C13/14 IEC socket, so a replacement power cord should be terminated in a C19 IEC plug.
The A35.8 can be used in a number of different speaker configurations. For examples of typical configurations see System configurations.
Each channel of the A35.8 can be connected directly to a loudspeaker of between 2Ω and 8Ω impedance.
Note that each pair of channels must both use the same type of input.
Alternatively, any adjacent pair of channels can be connected to a single loudspeaker in bridged mode to achieve a higher power output.
This will attenuate the input so the loudspeaker sounds as loud as if it was connected using a direct connection to one channel. This makes it easier to have a mixture of directly connected loudspeakers, and bridged loudspeakers, in a single configuration.
Alternatively, set the channel switch to 3: BRIDGED +6dB. This leaves the input unattenuated, so the bridged loudspeaker will sound 6dB louder than one connected directly to a single channel.
Four channels can be used to connect separately to the bass and treble units of a pair of loudspeakers to drive them in bi-amped mode. Because of the way the outputs are configured internally the right loudspeaker should use two odd-numbered channels, and the left loudspeaker should use two even-numbered channels, as shown above.
The terminals can accept speaker cables terminated with bare wires, spade terminals, or banana plugs.
For the best sound quality connect the red wire from each speaker to the red terminal marked + and the black wire from each speaker to the black terminal marked –.
To connect bare wires unscrew the terminal, pass the bare wire through the hole in the terminal bolt, and clamp the wire in place by screwing the terminal back down hand tight.
While no damage will occur, it is not recommended to have both the XLR and RCA inputs of a channel connected at the same time.
If you are using the RCA inputs use high quality stereo RCA leads.
If you are using the XLR inputs use balanced XLR cables.
If this cable is not suitable for your power outlets please contact your supplier for an alternative cable.
Note: See Phase for information about getting the best sound from your A35.8.
WARNING: Always disconnect the A35.8 from the mains power before connecting or disconnecting any cables.
The A35.8 will go into standby mode, indicated by the front panel light dimly illuminated.
The indicator light will blink for a few seconds before staying on.
The bridging capabilities of the A35.8 allow it to be used in a variety of two- and multi-channel system configurations, in some cases with additional amplifiers, to suit most system requirements.
This section describes some typical configurations, with information about how you would connect the A35.8 and other amplifiers in each system.

These instructions help you get the best possible sound from your A35.8.
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:
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.
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.
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.
By default, if no signal is present for 20 minutes the A35.8 will automatically go into standby to save power.
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:
