The TPA-1 is first and foremost an incredible two-channel audio preamplifier that uniquely combines hand-selected thermionic
(tube) technology while at the same time offering both IR and ADA Bus® remote control of input selection,
volume, mute, on/off, tone and loudness on/off as well as the iPod. The TPA-1’s remote control stage is
completely relay driven, preserving the analog signal path for sound even a purist will relish.

At the heart of the TPA-1 lie three different tube stages. In addition to the preamplifier tube stage, the
tone controls also pass through their own tube stage.  The TPA-1 features a
record output making it possible to share the fabulous iPod sound through a multi-room system.

The TPA-1 has three additional inputs, and for those who still enjoy vinyl, ADA offers the PP-1200 Phono
Preamplifier (for moving magnet cartridges). The TPA-1 can also be ordered without the iPod docking
base. Here, the record output can now be used as a input for a fourth source component.
The TPA-1 is encased in a nickel-plated aluminum chassis.
