GRA00046.1-[CA]60P 12/03/01 16:52 Page 3

We are convinced it will give you many hours of
listening pleasure.
The 60P is a powerful, high-quality stereo power
amplifier with an output of outstanding clarity and purity.
It complements our PA20R and PA10 preamplifiers in
performance and appearance.The 60P is an ideal entry
into the world of high-end separate component systems.
It is also perfect for multi-amplifier installations.
low intermodulation distortion
The theoretically-ideal amplifier
reproduces sound perfectly over an infinite
range of frequencies – starting from well
below the audible range and extending far
above the capabilities of human hearing.
Although sound outside the human hearing
range of approximately 20 to 20,000 Hz
cannot be heard,it can significantly distort
the quality of music reproduction through
an effect that audio engineers call
‘intermodulation distortion’.This type
of distortion moves imperfections that
originate outside the hearing range back
into the audible frequencies.To minimise
this effect,TAG McLarenAudio amplifiers
have a frequency response which extends
both above and below the range of normal
human hearing.
welcome welcome

Thank you for purchasing theTAG McLarenAudio stereo power amplifier 60P.
straight line technology
To prevent intermodulation distortion,
an amplifier must respond to very low
frequencies but block any Direct Current
(DC).This is traditionally achieved using
capacitors, which also block some of the low-
frequency signal. In the 60P,a feedback
circuit eliminates DC offset voltage and
allows the signal path to be direct coupled
without any capacitors.This arrangement,
which we atTAG McLarenAudio call
‘Straight LineTechnology’, is easy to describe
but not easy to realise.The design has taken
our expert engineers years to perfect.
supersonic high-frequency response
In order to reproduce high frequencies,the
60P is constructed using highly-rated,high-
precision components.The circuit has been
painstakingly designed to avoid any possibility
power amplifier 60P
GRA00046.1-[CA]60P 12/03/01 16:52 Page 5

of signals picking up interference and to
minimise the effects of intermodulation.
sophisticated muting
The 60P has a sophisticated muting system,
which stops you hearing loud, annoying
switching noises and protects the amplifier
and loudspeakers.
convenient connections
A signal output is provided to connect
another power amplifier in multi-amplifier
systems.It may also be used to tailor the
input characteristics for special purposes.
The loudspeaker output terminals are
duplicated for your convenience in case
you wish to bi-wire your loudspeakers.
substantial power
The 60P’s power rating of 60 watts is
very conservative,as the 60P can typically
provide 72 watts into 8 Ω,115 watts into
4 Ω,and over 150 watts into 2 Ωfor a short
period. Performance of this calibre is
essential to drive even the least sensitive
loudspeakers without distortion, and has
been achieved through the use of a large
power supply (which accounts for the high
weight of the 60P) and highly-specified
output circuitry.Separate power supplies
for each channel maximises channel
separation.
The 60P gives you power with true
hi-fidelity.

We know you are keen to get your 60P working. This section will
have you listening to your favourite music as quickly as possible.
If you fold out the front cover of this manual you will locate
diagrams which will help you find your way around your 60P(1).
Make sure that all the components of your audio system are
disconnected from the AC supply whenever you change any
connections.
On the back of your 60P, you will find four pairs of loudspeaker
terminals, each pair consisting of one red and one black.
The terminals on the back of the 60P use BFA(2) sockets.
The BFA plug pushes into the middle of the terminal.

lettering that you will find on the panels of your 60P
2. In models for countries where the AC supply is 115 V, the terminals accept 4 mm
‘banana’ plugs instead of BFA plugs. 4 mm plugs are not permitted in Europe.
Please see page 15 for more details of the terminals

individual shelves and are not stacked one on top of another
GRA00046.1-[CA]60P 12/03/01 16:52 Page 9

Use high-quality loudspeaker cable terminated in BFA plugs(1) to
connect the red terminal of your right loudspeaker to one of the
red(2) terminals marked RIGHT CHANNEL OUTPUT on the back
of your 60P. Then connect the black terminal of your right
loudspeaker to one of the black terminals marked RIGHT
CHANNEL OUTPUT on the back of your 60P. Connect the left
loudspeaker to a pair of LEFT CHANNEL OUTPUT terminals in
the same way.
loudspeaker
connection
You will need a preamplifier (such as our PA10 or PA20R)
connected to a sound source (such as our CD player CD20R or
tuner T20) to feed into your 60P. Use a good-quality, screened
phono-phono audio cable to connect the output of your
preamplifier to the sockets marked INPUT left and right on
the back of your 60P.
Check that the power button is out so that power is off when
you plug in(1). Using the cable supplied, connect the socket on
the back of your 60P to an AC supply outlet. For the best sound
quality, we recommend that you do not use multi-plug adaptors.
Press the power button in. The blue power LED will come on.
Wait for about 10 seconds for the muting system to switch off(2).
Start playing your sound source.
Turn up the volume, sit back and enjoy the music.

1. The power button is a latching switch. One press will hold it in, the next will
release it
2. The output is muted when the power is switched on to allow all the voltages to
stabilize. This protects your 60P and your loudspeakers and prevents unpleasant
noises from upsetting your listening experience
1. If you prefer to use a cable which does not have BFA plugs, please see page 14
2. If your loudspeaker terminals are not colour coded – red corresponds to positive
(+) or signal and black corresponds to negative (-). For each channel the
terminals of the same colour are connected together

grounding your
system
The INPUT left and right on the back panel of your 60P accepts
the output of a high-quality preamplifier (such as our PA10 or
PA20R)(1).
To simplify multiple power amplifier configurations, additional
OUTPUT left and right sockets are provided. These sockets are
connected in parallel with the INPUT sockets of the same channel.
In addition the OUTPUT sockets provide the facility to modify
the input impedance of the 60P by using a phono plug loading
module. Please consult your retailer for further information.

signal input and output grounding
The AC mains supply normally operates at either 50 or 60 Hz
(depending on which country you are in). Under some
circumstances this can cause an audible hum in your
loudspeakers.
Should you have any problems with hum in your system,
please contact your retailer.
To minimise the possibility of mains hum in your system:
do not link the ground terminals of separate audio units
together.
use screened cable for your signal connections and keep
the left and right channel cables close together.
All the units in the TAG McLaren Audio F3 Series range are
double insulated and do not require safety ground connections.
Your system does not need to be connected to ground (audio
engineers call this ‘floating’). However, if you want to ground
your system, please contact your retailer who will be able to
assist you.
1. The INPUT can accept a line output from a signal source such as a CD player
but, unless the source has a wide-ranging variable output, there will be no
volume control and the sound level may be excessive. This could result in
damage to your loudspeakers

The connection between your 60P and your loudspeakers is
crucial to the sound quality of your entire audio system. Please
follow these recommendations to achieve the best results.
Your 60P is specified to operate with 8 Ωloudspeakers, but it
can be used with 4 Ωloudspeakers. The 60P may also be
connected to loudspeakers which have a transient impedance
of less than 4 Ω(1).
Always switch off your 60P before changing any connections.
Always use high-quality loudspeaker cable.
On the back of your 60P you will find four pairs of loudspeaker
terminals. For each stereo channel (i.e. right and left), there is
one pair of black terminals and one pair of red. This duplication
of the terminals allows you to bi-wire the loudspeakers as
explained on page 17.
We recommend that you use loudspeaker cables terminated in
BFA plugs or spade terminals. These plugs are designed to fit the
terminals on the back of the 60P(1). The BFA plug and socket
ensures that you cannot touch the high-voltage output conductors.
Screw the knob of the terminal all the way in and push the plug
into the centre of the knob.
If you do not have BFA plugs, you can use ‘spade’ connectors.
Unscrew the terminal enough to push the spade into the slot in the
side of the terminal, then tighten the terminal by hand. You should
not use tools to tighten the terminal; over-tightening will reduce
the sound quality.
If you choose to use bare wire, there is a hole in the side of the
terminal to accommodate it. Make sure that there are no strands
of wire sticking out of the terminal.

1. The BFA connector complies with current EU safety standards, which do not
allow the use of 4 mm ‘banana’ plugs. 4 mm terminals are permitted (and are
fitted to the 60P) in countries where the AC supply is 115 volts

GRA00046.1-[CA]60P 12/03/01 16:52 Page 15

The simplest way to connect your loudspeakers is to run a single
cable (consisting of two wires) to each one. For each stereo
channel connect the red terminal on the loudspeaker to the red
terminal on the 60P. Repeat for the black terminals(1).
If your loudspeakers have separate connections for high and low
frequencies make sure these are linked together.
With many high-quality loudspeakers, you can make separate
connections to the high- and low-frequency drivers(1). In such
cases, you may want to run separate cables for the high and low
frequencies as shown in the diagram. To do this, you will need to
remove the links, provided as part of the loudspeaker, which
connect the drivers. Please refer to your loudspeaker instructions
to find out how to do this.
Bi-wiring provides separate paths for high- and low-frequency
signals, improving the sound quality in many cases.

connecting loudspeakers connecting loudspeakers
1. Connecting black to black and red to red ensures that the ‘phasing’ is correct.
If this is wrong it can affect the sound. If your loudspeaker terminals are not
colour-coded, black corresponds to negative (-) and red corresponds to positive
(+) or signal. Please refer to your loudspeaker manual for details
2. This diagram, and those that follow, are for illustrative purposes only; they are
not to scale and do not show all connections
1. The ‘driver’ is the mechanism inside the case of the loudspeaker which actually
makes the sound. Most high-quality loudspeakers have drivers for high, low and
often middle frequencies and the capability to connect them separately.
However, the lack of this facility is not necessarily a sign of low quality
(as some of the finest loudspeakers in the world have proved)

To improve the sound further, you can use separate amplifiers for
high and low frequencies. This will allow you to increase the volume
without distorting the sound. As each amplifier is operating in a
smaller bandwidth, intermodulation distortion may also be reduced.
Connect the left and right output of a preamplifier (such as our
PA10) to the INPUT left and right on one of your 60Ps. Also
connect the left and right preamplifier outputs to the other 60P.
Then connect one 60P’s loudspeaker terminals to the high-
frequency drivers of the left and right loudspeakers. Use the
second 60P to connect to the low-frequency drivers(1).
An alternative connection method is shown here. This arrangement
has the added advantage of allowing you to place each amplifier
close to the loudspeaker it is feeding, thus enabling you to connect
them together with short cables.
Connect the right channel output of a preamplifier (such as our
PA20R) to INPUT left on one of your 60Ps and the left channel
output of the preamplifier to INPUT left on the other 60P.
On each 60P connect OUTPUT left to OUTPUT right.
On each amplifier, connect one of the stereo outputs to the high-
frequency driver and the other to the low-frequency driver.

running in and warming up
TAG McLaren Audio equipment is designed to give optimum
performance for many years.
Just like a high-quality car, the performance of your 60P will
improve during the first few hours of operation. The electronic
components will then have reached and settled down to near-
perfect specification.
Every time you switch on your 60P, the performance will improve
until the components reach their optimum operating temperature.
running in
warming up
Some high-quality loudspeakers have separate drivers for the
middle frequency range as well as high and low. In such cases,
it may be possible (for details refer to your loudspeaker
instructions) to run separate cables for each frequency range
to tri-wire the loudspeakers.
If you wish to do this, you will need to connect two wires to one
terminal. We recommend that you use stackable BFA plugs for
this purpose. These are available from your retailer.
The arrangements described above, and on previous pages, are
only suggestions and do not cover all the connection possibilities
for amplifiers and loudspeakers.
If you want to expand your audio system, please contact your
retailer who will be happy to discuss your specific requirements.

care and maintenance
1. You cannot open the fuse carrier drawer while the plug is in the socket
There is a fuse in the power socket on the back of your 60P.
To change the fuse, unplug the power cable and pull out the fuse
carrier drawer(1).
The fuse carrier contains a spare fuse; this is the first one that you
see when you open the carrier.
There are no other user-serviceable parts inside the 60P.
In order to maintain the appearance of your 60P, you can clean it
as follows:
before cleaning, always disconnect your 60P from the AC
supply.
any grease or dirt on the case may be removed with a soft,
lint-free cloth moistened slightly with a mild solution of warm
water and detergent or washing-up liquid. Do not use any
other solutions. Do not use any solvents or abrasives.
take great care not to get any liquid inside the case.
If this happens, you should have your 60P serviced.
