Connecting Other Components

1. Make sure your amplifier and other
components are turned off.

2. Connect each component's
Output/Play jacks to the corresponding
Input jacks on the back of your amplifier
and, if available, the component’s
Input/Record jacks to the Output jacks
of the HK 980. Use the white, black or
gray plugs to connect Left channel jacks;
use the red plugs for Right channel
jacks.

3. A record player with MM cartridge
must be connected to the Phono Input
jacks and a separate ground wire to the
ground terminal screw above.

Wired Remote Control

To control your amplifier with an
external infrared remote sensor,
connect the wire from the remote sensor
to the REMOTE IN jack on the back
panel. Or, if another stereo component
has a built-in infrared remote sensor
and a Remote Output jack, it may be
possible to connect this jack to the
REMOTE IN jack of your amplifier. All
Harman Kardon products with »Remote
In« and »Remote Out« jacks are
compatible with one another, except for
the Citation 22, 24 and 25.
Other manufacturers' remote sensors
and components may not be compatible,
but it will not hurt to experiment. A
second wire may be used to connect
your amplifier's REMOTE OUT jack to

component. Continue this process to
include additional components (if
compatible).

Connecting Speakers

1. For best performance, use high
quality speaker cables. However,
ordinary copper wire can be used if
the gauge meets the following
requirements:

Wire Min.
Length Diameter

Up to 2.5 meter 1 mm
Up to 4 meter 1.25 mm
Up to 6 meter 1.6 mm
Above 6 meter 2-2.5 mm

2. Avoid rolling excess wire with or near
signal interconnects.

External Power Amplifiers

For applications where higher power is
desired, connect the Pre-Out Jacks to
the Main In Jacks of an external power
amplifier. The level of the output can be
adjusted between -3 and +3 dB with an
internal button. To adjust the level,
gently insert a small screwdriver into the
button and turn clockwise to increase or
counter-clockwise to decrease the
output level.

Speaker System 2

IMPORTANT: When connecting two
pairs of speakers, determine the
impedance of each pair by looking on
the back of the speakers, in your
owner's manual, or by contacting your
dealer or manufacturer.

You can listen to two pairs of
speakers at the same time ONLY if
the impedance of EACH speaker is
NOT LESS THAN 8 Ohms.

WARNING: Do not play sets of

speakers simultaneously except as
recommended above. Amplifier may
overheat.

AC Power

Plug the cord into a 230 VAC wall
socket. Power indicator will light up to
indicate power ON. To completely
disconnect the power input, the main
plug must be disconnected from the
mains.

Independent Remote Control

The system remote of the HK 980 can
control the amplifier and compatible
Tuners, CD Players and CD Recorders.
The remote In jack of units without an
integrated IR receiver must be
connected to the amplifier's remote

Important Notes:

• To remote control a tuner, CD

Recorder or CD Player, the
appropriate input (”TUNER”, ”CDR”
or ”CD”) must have been selected
with the source buttons of the remote
control (selecting on the front panel is
not sufficient).

• Note that DVD players or tape decks

cannot be controlled by the remote.

• To control a compatible CD

Recorder ”CDR” must be selected as
input and the drive to be controlled
(CDP or CDR) must be selected
appropriately with the ”CDP SELECT”
or ”CDR SELECT” buttons.

Operating Conditions

The control unit operates effectively
within a distance of 7 meters and an
angle of 30° from the amplifier. Using
the control near fluorescent lights may
shorten this range, as will any dust or
dirt that accumulates on the front of the
remote control or the remote sensor
area of the amplifier. Also avoid
blocking the line of sight between
amplifier and remote.

The control unit is powered by two AA
batteries, included with your amplifier.
When you replace weak batteries,
replace both at the same time. When
the remote is to be unused for an
extended period, remove the batteries
to prevent damage from corros

GENERAL DESCRIPTION

The OP275 is the first amplifier to feature the Butler Amplifier
front-end. This new front-end design combines both bipolar
and JFET transistors to attain amplifiers with the accuracy and
low noise performance of bipolar transistors, and the speed and
sound quality of JFETs. Total Harmonic Distortion plus Noise
equals that of previous audio amplifiers, but at much lower sup­ply currents.

A very low l/f corner of below 6 Hz maintains a flat noise density
response. Whether noise is measured at either 30 Hz or 1 kHz,

it is only 6 nV/√

the OP275 its high slew rates to keep distortion low, even when

large output swings are required, and the 22 V/µs slew rate of

the OP275 is the fastest of any standard audio amplifier. Best of
all, this low noise and high speed are accomplished using less
than 5 mA of supply current, lower than any standard audio
amplifier.

Hz. The JFET portion of the input stage gives

PIN CONNECTIONS

8-Lead Narrow-Body SO 8-Lead Epoxy DIP

(S Suffix) (P Suffix)

Improved dc performance is also provided with bias and offset
currents greatly reduced over purely bipolar designs. Input off­set voltage is guaranteed at 1 mV and is typically less than

200 µV. This allows the OP275 to be used in many dc coupled

or summing applications without the need for special selections
or the added noise of additional offset adjustment circuitry.

The output is capable of driving 600 Ω loads to 10 V rms while

maintaining low distortion. THD + Noise at 3 V rms is a low

0.0006%.

The OP275 is specified over the extended industrial (–40°C to
+85°C) temperature range. OP275s are available in both plastic

DIP and SOIC-8 packages. SOIC-8 packages are available in
2500 piece reels. Many audio amplifiers are not offered in
SOIC-8 surface mount packages for a variety of reasons; how­ever, the OP275 was designed so that it would offer full perfor­mance in surface mount packaging.

HIGH FIDELITY HEADPHONE AMPLIFIER

FEATURES DESCRIPTION

• 80 mW into 600 Ω From a ±12-V Supply at

0.00014% THD + N

• Current-Feedback Architecture

• Greater than 120 dB of Dynamic Range

• SNR of 120 dB

• Output Voltage Noise of 5 µVrms at

Gain = 2 V/V

• Power Supply Range: ±5Vto±15 V

• 1300 V/µs Slew Rate

• Differential Inputs

• Independent Power Supplies for Low

Crosstalk

• Short Circuit and Thermal Protection

APPLICATIONS

• Professional Audio Equipment

• Mixing Boards

• Headphone Distribution Amplifiers

• Headphone Drivers

• Microphone Preamplifiers

The TPA6120A2 is a high fidelity audio amplifier built
on a current-feedback architecture. This high
bandwidth, extremely low noise device is ideal for
high performance equipment. The better than 120 dB
of dynamic range exceeds the capabilities of the
human ear, ensuring that nothing audible is lost due
to the amplifier. The solid design and performance of
the TPA6120A2 ensures that music, not the amplifier,
is heard.

Three key features make current-feedback amplifiers
outstanding for audio. The first feature is the high
slew rate that prevents odd order distortion
anomalies. The second feature is current-on-demand
at the output that enables the amplifier to respond
quickly and linearly when necessary without risk of
output distortion. When large amounts of output
power are suddenly needed, the amplifier can re­spond extremely quickly without raising the noise
floor of the system and degrading the signal-to-noise
ratio. The third feature is the gain-independent fre­quency response that allows the full bandwidth of the
amplifier to be used over a wide range of gain
settings. The excess loop gain does not deteriorate at
a rate of 20 dB/decade.
