Creek Audio OBH-11 Manuel utilisateur

Thank you for purchasing the OBH-11 Headphone Amplifier. You are now in

possession of a State of the Art product. The functions and operation of the OBH-11

are extremely simple. However, the following notes are provided to explain all

aspects of its design and use.

OVERVIEW

The OBH-11 is a miniature audio amplifier, designed

specifically to drive a single pair of low to medium

impedance (30

-300

) headphones from a line level

source. It is more efficient to have a small amp to do

this rather than waste the power of a full size one when

only driving headphones.

The OBH-11 is compatible with any source at line level.

For example: an average output level CD player can be

connected directly to the input of the OBH-11, just as it

could also be used in conjunction with a stand-alone

pre-amplifier or integrated amplifier which doesn't have

a headphone output.

The OBH-11 is not designed to be connected to the

speaker output of an integrated or power amplifier.

Output level can be controlled by the high quality

volume control on the front panel.

INPUT AND OUTPUT CONNECTIONS

The OBH-11 has two pairs of stereo phono sockets (RCA jacks) on the rear panel.

The first pair is the Input from any line level source, direct from the source or via the

tape output of an amplifier. The second pair of sockets, marked ‘Output’, are to chain

link the signal onto the next component in the system. Therefore, the OBH-11 can

be driven from the Tape Output of an amplifier and the second set of sockets can be

used to link the signal to the Tape recorder input. There is a 2.1mm DC power jack,

with centre positive pin, for connection to a custom Creek OBH type power supply

adaptor. On the front panel there is one 1/4" (6.3mm) stereo socket, for plugging in

the headphones.

INSTALLATION AND OPERATION

Connect the OBH power supply adaptor to the mains socket. Find a suitable place

for the OBH-11 and plug the DC power lead into the rear panel DC jack socket.

Connect a pair of high quality interconnect cables from the output of the source to

the input sockets on the rear of the OBH-11. Refer to the wiring diagrams showing

the different options for connecting the OBH-11 to your system.

Plug the headphones into the socket on the front panel. Push the On/Off button on

the rear to power-up the OBH-11. The small green LED on the front panel will light

when it is ready for use. The front panel volume control should be set to the desired

signal level.

POWER SUPPLY REQUIREMENTS

In common with all electrical appliances, the OBH-11 needs a power source. The

requirements for the OBH-11 is 24 Volts DC at 150 milli Amps current. A custom

power supply has been provided to run it, which must be connected to the unit via

the DC inlet (2.1mm positive centre pin power jack) on the rear panel. The power

supply adaptor should be plugged into the mains socket which should be matched

for the voltage of the country of use.

N.B. Due to the circuitry charging-up it is normal to hear a small thump through the

headphones during switch-on.

Note 1: The OBH should be placed away from transformer hum fields for

low noise operation.

Note 2: When new, it is necessary for the OBH to be ‘burned-in’ for at least

24 hours before its full sound quality potential can be realised.

Note 3: Listening to excessive sound pressure levels can seriously damage

your hearing. Be careful and enjoy the music.
