Your A60 is supplied with the following components:
The A60 is designed to be connected directly to two
loudspeakers.
• Connect the A60 to each channel of the preamplifier or
• Trigger cable.
• Mains cable.
• One pair of white gloves.
The terminals can accept speaker cables terminated with
spade terminals or banana plugs.
To connect to two loudspeakers
processor using either the unbalanced RCA input, or
the balanced XLR input, as appropriate.
• Put the INPUT switch in the appropriate position for
the inputs you are using.
Please use the gloves when handling the unit to avoid
leaving fingerprints.
• Connect the LEFT SPEAKER + and – terminals to the
If you are using the RCA inputs use high quality stereo
RCA leads.
If any of these are missing please contact your supplier.
We recommend you retain the packaging in case you need
to transport the unit at a later date.
• Connect the RIGHT SPEAKER + and – terminals to the
If you are using the XLR inputs use balanced XLR cables.
2 Positioning
For BEST results position the A60 on a stable audio rack.

WARNING: Leave a space of at least 50mm
around the sides and top of the amplifier to allow
adequate ventilation.
The on/off switch is on the back panel.

appropriate terminals on the left speaker.
appropriate terminals on the right speaker.
For best results with single-wire connections use the
lower pair of terminals.
To bi-wire to two loudspeakers
The A60 provides two pairs of loudspeaker terminals for
each channel, to allow you to connect to the treble and
bass units of each speaker using separate cables.
• Connect one pair of the LEFT SPEAKER + and
– terminals to the treble unit on the left speaker.
• Connect the other pair of the LEFT SPEAKER + and
– terminals to the bass unit on the left speaker.
• Wire the right speaker in a similar way.
The front-panel indicator shows the standby/on status:
For best results when bi-wiring use the lower pairs of
terminals for the mid/high units and the upper pairs of
terminals for the bass units.
5 Connect power
Connect the power connector on the back panel to your
power outlet using the mains cable supplied with the A60.
If this cable is not suitable for your power outlets please
contact your supplier for an alternative cable.
See Best sound, page 8, for information about getting
the best sound from your A60.

WARNING: Before connecting power check that
the required supply voltage, indicated on the back
panel, corresponds to your local AC supply.
If a different voltage is stated on the type plate do not
connect the amplifier to the mains power, and seek
advice from your dealer.

WARNING: Always disconnect the A60 from the
mains power before connecting or disconnecting
any cables.
• Low intensity indicates standby.
• Bright indicates on.

Primare products together, using the trigger cable
supplied with each product, so they switch on or to
standby in sync with the PRE60.
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:

3. Object or liquid entry
This is a Class 1 device and must be earthed.
Take care that objects do not fall and liquids are not spilled
into the enclosure through any openings. Liquid-filled objects
such as vases should not be placed on the equipment.
The power switch is a single-pole switch. When the switch
is in the “Off” position, the appliance is not completely
disconnected from the main power.
4. Ventilation
10. Power-cord protection
Do not place the equipment on a bed, sofa, rug or similar
soft surface, or in an enclosed bookcase or cabinet, since
ventilation may be impeded. We recommend a minimum
distance of 50mm around the sides and top of the
appliance to provide adequate ventilation.
Power supply cords should be routed so that they are not
likely to be walked on or pinched by items placed upon
or against them, paying particular attention to cords and
plugs, and the point where they exit from the appliance.
11. Grounding
5. Heat
Ensure that the grounding means of the appliance is not
defeated.
Locate the appliance away from naked flames or heat
producing equipment such as radiators, stoves or other
appliances (including other amplifiers) that produce heat.
12. Power lines
Locate any outdoor antenna/aerial away from power lines.
6. Climate
13. Non-use periods
The appliance has been designed for use in moderate
climates.
7. Racks and stands
Only use a rack or stand that is recommended for use with
audio equipment. If the equipment is on a portable rack it
should be moved with great care, to avoid overturning the
combination.
8. Cleaning
Unplug the unit from the mains supply before cleaning.
The case should normally only require a wipe with a soft,
damp, lint-free cloth. Do not use paint thinners or other
chemical solvents for cleaning.
We do not advise the use of furniture cleaning sprays or
polishes as they can cause indelible white marks if the
unit is subsequently wiped with a damp cloth.
9. Power sources
This appliance must be connected to a mains socket
outlet using the supplied power cord. To disconnect
this apparatus from power, you must disconnect the
power cord. Make sure the power cord is always easily
accessible.
Only connect the appliance to a power supply of the type
described in the operating instructions or as marked on
the appliance.
If the unit has a stand-by function, a small amount of
current will continue to flow into the equipment in this
mode. Unplug the power cord of the appliance from the
outlet if left unused for a long period of time.
14. Abnormal smell
If an abnormal smell or smoke is detected from the
appliance, turn the power off immediately and unplug the
unit from the wall outlet. Contact your dealer immediately.
15. Servicing
You should not attempt to service the appliance beyond
that described in this handbook. All other servicing
should be referred to qualified service personnel.
