Introduction
Connecting to Headphone Ou
tputs
Most CD players, MP3 players, personal computers, medium to high end stereo receivers
and other audio sources with headphone outputs often make use of single-chip , single-
ended output
headphone
amplifier devices. These devices
may without load pr
oduce
fairly reasonable low
-
distortion sound but
often
lack adequate power to effectively drive
headphones.
This results in low
-
volume, inferior quality (high distortion) reproduction of the audio signal
by headphone sets. Bass signals sound flat and or hi
gher frequencies
sound
distorted
when listening to audio tracks from these inferior
single
-
chip
headphone amplifiers.
This
can be observed when you turn up the volume to your headphones and is evidenced by
increased distortion of the audio signal.
The
X3HA
Headphone Amplifier provides higher headphone drive levels and enhances
audio quality thereby overcoming the weaknesses inherent in lower quality headphone
amplifiers.
As mentioned above, headphone amplifiers in CD players, MP3 players, personal
computer
s and stereo receivers, in most cases, can reproduce audio signals with very
little distortion as long as there is little to no load connected to their output.
The
X3HA
takes advantage of this by firstly presenting a negligible load to the output of
these
headphone amplifiers. The
X3HA
then uses it s own high quality low-
noise pre
-
amplifier stage that drives the bipolar transistor output stages. The
X3HA
employs the
same amplifier design as that used in high end speaker amplifiers. A DC
-
DC converter is
use
d to convert the battery voltage to a full dual
-
rail supply as found in high end stereo
amplifiers.
Connecting to Line Outputs
The
X3HA
can also be connected to the line output of audio playback devices. In most
cases the line output provides a higher qua
lity low distortion audio signal but is insufficient
for driving headphones. The
X3HA
can
amplify the line output signal to a level suitable for
driving headphones. This allows you to take advantage of the superior quality of line
output audio.
