Congratulations on selecting your new A35.2 Stereo Amplifier
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.
3.1. Unpack the A35.2
3.2. Connect speakers
The A35.2 is designed to be connected directly to a pair of loudspeakers of 8Ω impedance.
- Connect the left and right loudspeakers to the corresponding terminals on the back panel.
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.
NOTE: contrary to the back panel silk screen label, there is no need to connect a “short” wire as the circuit was changed after the back panels were manufactured.
Advice on positioning your speakers
For best results your speakers should be positioned about 2-3m apart, at least 20cm from the rear wall and at least 50cm from any side wall. The tweeter or high frequency unit in the speaker should be at head height when you are seated, listening to the speaker.
3.3. Connect inputs
- Connect the A35.2 to the preamplifier or processor using either the left and right RCA inputs, or the left and right XLR inputs.
- Put the input selector switches in the appropriate positions.
If you are using the RCA inputs use high quality stereo RCA leads.
If you are using the XLR inputs use balanced XLR cables.
3.4. Connect power
- Plug one end of the mains cable supplied with the A35.2 into the power connector on the back panel, and connect the other end to a wall socket.
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 A35.2.
WARNING: Always disconnect the A35.2 from the mains power before connecting or disconnecting any cables.
- Switch on the A35.2, using the switch on the back panel.
The A35.2 will go into standby mode, indicated by the front panel light dimly illuminated.
3.5. Switch on
- Press the front panel standby switch, in the middle of the Primare logo.
The indicator light will blink for a few seconds before staying on.
If no signal is present for 20 minutes the A35.2 will automatically go into standby to save power.
3.6. Automatic standby
By default, if no signal is present for 20 minutes the A35.2 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 A35.2 off and then on again using the switch on the back panel.
The following diagram explains the function of each of the connectors on the back panel:
NOTE: contrary to the back panel silk screen label, there is no need to connect a “short” wire as the circuit was changed after the back panels were manufactured.

These instructions help you get the best possible sound from your A35.2.
6.1. Phase
The phase of the AC supply can make a significant difference to the sound.
Use the Polarity Pen supplied with the A35.2 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:
6.2. 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.
6.3. RS232
The RS232 input allows you to connect the A35.2 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.
6.4. Trigger
For convenience the A35.2 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 A35.2 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 A35.2, 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.
6.5. Sense
The A35.2 includes an Auto Sense feature that will put the amplifier into standby if no signal is received for 20 minutes. The amplifier will automatically come out of standby if an input is sensed.
To enable Auto Sense
- Switch the SENSE switch to the ON position.
6.6. Bridged mode
The A35.2 can be used in Bridged Mode, to give up to four times the output power to a single loudspeaker.
To configure the A35.2 in Bridged Mode
- Switch off the A35.2 using the switch on the back panel.
- Switch the OUTPUT switch to the BRIDGED position.
- Connect the input signal to the L RCA or XLR input.
- Switch the INPUT switch to RCA or XLR according to which input you are using.
- Connect the loudspeaker between the RIGHT + and LEFT – speaker terminals.
- Optionally switch the GAIN switch to the +6dB position to give a higher output.
The A35.2 will now operate in Bridged Mode.
NOTE: There is no need to connect a “SHORT” wire as indicated by the text on the back of the amplifier.
