HEADPHONE AMPLIFIER

he OBH-ll is a miniature audio

I amplifier, designed specifically to

drive headphones (from 30 ohms

to 300 ohms) from a line level source,

The purpose is to eliminate the use of a

full size amplifier for boosting the
power, if only headphones are used.

An average output level CD player
or Tuner can be connected directly to
the input of the OBH-ll, or it could also
be used in conjunction with other OBH
products, such as the OBH-8/9 Phono
Pre-amps and OBH-12 passive Pre-amp,
It would also work with a stand-alone
pre-amplifier or integrated amplifier with-
out headphone output, connected in the
tape loop. The volume control on the
front panel is designed to control the out-
put level,

Input and Output connections The
OBH-ll has stereo phono sockets (RCA
jacks) on the rear panel for input from
any line level source, together with a DC
power jack, for connection to a custom
OBH power supply aclaptert There is a
single 1/ " (6.3mm) stereo headphone
jack on the front panel. NB. Only one
source can be amplified as it only has
one stereo input.

Power Supply requirements. In
common with all electrical appliances,
the OBH-ll requires a power source,
and a custom power supply is provided
to run it, which must be connected to
the unit via the DC inlet (2.1mm posi-
tive centre pin power jack) on the rear
panelt Sound quality is greatly
enhanced by using the regulated 24V
OBH-Z High Grade Power Supply (as
opposed to the standard OBH-l). The
power supply may vary depending on
country of use,

No expense has been spared to
enable the OBH-ll headphone amp to
faithfully reproduce a music signal. Only
the highest quality components are used
in its classic amplifier circuitry, to achieve
low distortion and noise, with good
stereo separation.

Great care has also been taken to
match the output circuitry to the special
requirements of modern dynamic head-
phones, providing an extremely flat fre-
quency responset Audio bandwidth is
limited by input and output coupling
capacitors to prevent unwanted signals
damaging the headphones in user
