Thank you for purchasing the TAG McLaren Audio phono preamplifier PPA20.
The frequency response of the PPA20 meets the RIAA speci�cation, and a switchable lowfrequency (�rumble�) �lter is included which meets the IEC speci�cation. An additional switchable bandpass �lter allows you to remove noise at both low and high frequencies and a facility is also provided to select mono reproduction.
low intermodulation distortion
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 both above and below the range of normal human hearing.
straight line technology
We are convinced it will give you many hours of listening pleasure.
The PPA20 is dedicated to those who want to get the very best out of their vinyl records. It can accept the output of two turntables and includes the capability to fine tune the signals of both independently.The PPA20 also has switchable filters to enhance your enjoyment of older records which may be damaged or were recorded using non-standard equalisation.

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 affect the quality of music reproduction through
To prevent intermodulation distortion, a preamplifier 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 PPA20, a feedback circuit eliminates DC offset voltage and allows the signal path to be direct coupled without any capacitors.
