Getting Started
Thank you for purchasing the Rotel RA-1070
Stereo Integrated Amplifier. When used in a
high-quality music audio system, it will pro-
vide years of musical enjoyment.
The RA-1070 is a full featured, high perfor-
mance preamplifier. All aspects of the design
have been optimized to retain the full dynamic
range and subtle nuances of your music. The
RA-1070 has a highly regulated power sup-
ply incorporating a Rotel custom-designed to-
roidal power transformer and custom-made
slit foil capacitors. This low impedance power
supply has ample power reserves, which en-
ables the RA-1070 to easily reproduce the most
demanding audio signals. This type of design
is more expensive to manufacture, but it is
better for the music.
