TAG MCLAREN AUDIO PPA20 User Manual - page 4
This arrangement, which we at TAG
McLaren Audio call ‘Straight Line
Technology’, is easy to describe but not
easy to realise. The design has taken our
expert engineers years to perfect.
time constant switching
The PPA20 has a sophisticated muting
system which protects your hi-fi and
prevents annoying, loud switching noises
from reaching the output. A preamplifier
that responds to low frequencies will ‘ring’
for a long time in response to the sudden
voltage changes that happen, for example,
when you select a different input. A muting
system that simply waited for the switching
transients to die down naturally would take
far too long to settle. To overcome this
problem the PPA20 incorporates a
technique developed by TAG McLaren
Audio called ‘Time Constant Switching’.
This changes the characteristics of the
preamplifier during input switching to
reduce the settling time so that the mute
period can be as short as possible.
versatile input loading
The inputs of the PPA20 have the correct
loading for moving magnet and moving coil
cartridges. Each input includes special load
terminals which allow you to tailor the
input to match any cartridge which may
need special, non-standard, loading
characteristics. Gain control is also
provided so that you can select the right
amount of amplification for your cartridge.
Loading and gain settings for each input are
retained in the memory of the PPA20.
high-quality circuitry
The circuits in the PPA20 are ‘no-
compromise’ designs using high-quality,
high-stability components to send a
smooth, clean signal to your amplifier for
excellent sound quality.
The PPA20 unveils, without any
compromise, all of the music information
in your record collection.
