We are convinced it will give you many hours of
listening pleasure.
The PA20R is a high-performance preamplifier which acts
as the command centre for your audio system. It has
microprocessor-controlled relays with gold-plated contacts
for its switching functions and, for added convenience, you
can select inputs, adjust the volume or mute the output by
remote control.‘Straight Line Technology’ gives the PA20R
exceptional sound quality with an unusually
wide and flat frequency response.
Furthermore, by painstaking attention to
detail,TAG McLaren Audio engineers have
ensured that the versatile control facilities
do not affect the excellent sound quality.
In particular, the ‘Time Constant Switching’
system ensures that the muting period is
short even though the frequency response
reaches as low as 0.1 Hz.
versatile input
and recording selection
The PA20R has six selectable inputs and
three outputs for recording. A separate signal
path is provided for recording, with its own
independent input selector, so you can
record one piece of music while listening
to another.The microprocessor-controlled
relay switching system in the PA20R

Thank you for purchasing the TAG McLaren Audio preamplifier PA20R.
includes a lock-out function to prevent
feedback loops when using a tape recorder.
low intermodulation distortion
The theoretically-ideal preamplifier
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 McLaren Audio preamplifiers
have a frequency response which extends
