CLASS A HEADPHONE AMPLIFIER

Volume

OER-11 5E Headphone Amplifier

he OBH-115E is a class A' head-
I phone amplifier designed to drive
two pairs of 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 play-
er or Tuner can be connected directly to
the input of the OBH-11, 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 lack-
ing headphone output, connected in the
tape loop. The volume control on the
front panel is designed to control the out-
put level.

The OBH-IISE has been designed
with zero feedback and is fully ClassA
for improved performance

No expense has been spared to
enable the OBH-118E headphone amp
to faithfully reproduce a music signal.
Only the highest quality components are
used in its unique amplifier circuitry, to
achieve low distortion and noise, with

good stereo separation, including Alps
Blue Velvet volume potentiometer.

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 response. Audio bandwidth is
limited by input and output coupling
capacitors to prevent unwanted signals
damaging the headphones in use,

Input and Output connections. The
OBH-118E has two pairs of stereo
phono sockets (RCA jacks) on the rear
panel for input from any line level source
and chain linking to another product in a
tape loop circuit, together with a DC
power jack for connection to a custom
OBH power supply adapteri There are
two 1/4" (6.3mm) stereo headphone
jacks on the front panel

Power Supply requirements. A
custom High Grade regulated power
Supply (OBH-2) is provided to run the
OBH-115E. This must be connected to
the unit via the DC inlet (2.1mm posi-
tive centre pin power jack) on the rear
panel. The power supply may vary
depending on country of use.
