from the bottom of the unit. The feet may be removed from the outside, with no dis-assembly of the
chassis necessary.

The 9130 Amplifier can produce considerable heat during normal operation. The amplifier should be
placed on a hard, smooth surface to allow air to circulate beneath the unit. Additionally, allow at least
one inch of free space on either side, and several inches above and behind the amplifier to allow air
circulation around the heatsinks. This is particularly important when the unit is installed in a closed
cabinet.

In applications where the amplifier is driving low impedance and/or low efficiency loudspeakers at high
levels, thermal shutdown may occur if inadequate ventilation is provided. If this occurs, it may be
necessary to move the amplifier to a location with better free air circulation.

The amplifier should be located at least several inches away from sensitive components, (such as
preamplifiers, tuners, CD players, turntables, etc.) due to the possibility of audible hum or buzz from
magnetic radiation.

The 9130 Amplifier is configurable for either 100, 120, or 230 volt operation. This is accomplished by
moving the Voltage Selector on the printed circuit board. The procedure is detailed in the section
“CHANGING LINE VOLTAGE RATING”.

Make sure that the unit is configured for your local AC line voltage before attempted use. The
configuration is
over a range of 220 to 240VAC.)

16 gauge assembly. Should replacement ever be necessary, be sure to replace it with an identical cord.

Never remove the grounding pin from the male end of the cord. In applications where a grounded outlet

is not available, a ground adaptor should be employed, with the ground tab or wire of the adaptor

connected to a suitable earth ground.

The AC power cord of the amplifier must be connected to a receptacle capable of delivering a minimum

of 600 watts. The convenience outlets of some preamplifiers are not rated for this power level. Before

connecting the amplifier, be sure to check the rating of such outlets, and take into account the power

consumption of any other connected components to determine the total maximum power consumption.

single or dual banana plugs, spade lugs, pin plugs, or bare wires. If using bare wires, it is recommended
that the ends of the wire be tinned with solder so that no stray strands can cause a short circuit to the
chassis or adjacent terminals.

SOFT TURN-

ON/OFF

SYSTEM

The 9130 Amplifier is equipped with front panel mounted Gain Controls. These controls may be used
to attenuate the input signal to the amplifier. The maximum clockwise position of these controls applies
the full input signal to the amplifier. Intermediate positions of these controls will partially attenuate the
signal, and the full counter-clockwise position attenuates the input signal completely.

Most applications will dictate that these controls be set to their maximum clockwise position. In
situations of unusually high level signal sources, or for matching levels in multiple amplifier installa­tions, it may be desirable to use an intermediate position of the Gain Controls. Unless intentionally

introducing different gain levels in the two channels of the amplifier, these controls should normally be

set at the same rotational position.

In the Mono Mode, the Left Gain Control affects the overall gain of the amplifier. The Right Gain Control

has no effect.

The 9130 Amplifier may be operated in the normal two channel Stereo Mode, or may be converted

(bridged) to a higher power, single channel amplifier in the Mono Mode.

Operation of the Stereo/Mono switch must be performed with the amplifier off! Set the Stereo/Mono

Switch in the OUT position for Stereo Mode, or in the IN position for Mono Mode. Mono Mode operation

requires different input and output connections: consult the sections of the manual titled “Inputs” and

“Outputs”.

The 9130 Amplifier is equipped with a Soft Turn-On/Off System that gradually activates the amplifier’s

circuitry to avoid spurious noises as the power supply stabilizes.

At turn-off, this same system rapidly deactivates the amplifier’s circuitry before the power supply begins

to collapse, again eliminating any spurious noises.

THERMAL

PROTECTION

SYSTEM

The 9130 Amplifier is equipped with a Thermal Protection System that constantly monitors the

temperature of the heatsinks. When the heatsink temperature reaches a pre-determined level, the

amplifier’s circuitry is electronically shut down through the same system that provides the Soft Turn-

On function. When the heatsinks cool to a safe operating temperature, normal operation of the
amplifier resumes.

CIRCUIT HIGHLIGHTS

The 9130 employs a single ended, current source driven, differential input stage. This stage is
connected to the rest of the circuitry through a balanced push-pull current mirror system. A combination
current mirror and bias multiplier drive the final output stage driver emitter followers.
techniques are used that dramatically reduce harmonic distortion.

The final output stage uses two multiple lateral MOSFET’s (Metal Oxide Semiconductor Field Effect
Transistors) per channel. These devices, unlike conventional bipolar transistors, have a negative
temperature coefficient, which means that they do not exhibit “thermal runaway”. Thermal runaway is
a phenomenon whereby a transistor heats up as it conducts more current, which causes it to get hotter,
and conduct more current, and so on, until the device self destructs. Since MOSFET’s are inherently
self-protecting, no sonically degrading, complex circuitry is required to monitor and protect the output
devices.

Furthermore, these lateral MOSFET’s exhibit a very linear input to output transfer function. Their

connection in circuits and operating characteristics are very similar to vacuum tubes, which is perhaps

responsible for their widely recognized sonic trait of being very “musical” and non-fatiguing.
Conversion to Mono Mode is accomplished by driving the negative input (feedback point) of the right

channel with the output of the left channel. This causes the right channel to mirror exactly the output
of the left channel, but 180 degrees out of phase. This creates twice the voltage swing to be available
across the two red output binding posts. This simple method of bridging the amplifier (involving only
one resistor) eliminates the costly and sonically degrading inverter circuitry used in other amplifiers.

The Thermal Protection System consists of thermistors (temperature sensitive resistors) mounted to
the heatsinks, connected to a comparator system that activates when the heatsinks reach an unsafe

operating temperature. The output of the comparator system is connected to a small transistor switch

that turns off the input stage of the amplifier, which effectively shuts down the entire amplifier. When

the heatsinks cool to a safe temperature, the amplifier is turned on again.

Special linearizing

The Soft Turn On/Off System cooperates with the Thermal Protection System by sensing the output
of the high voltage power supply. At power up, when both the comparator and power supply have
stabilized to normal operating levels, the Soft Turn On System activates the amplifier circuitry through
the same transistor switch in the input stage. At power down, the system deactivates the amplifier

rapidly before the power supply begins to collapse. This system eliminates spurious noises during the

turn on/off cycle.
The power supply utilizes a large El type transformer with dual multi-tapped primaries to allow alternate

connections for world-wide voltage operation. Selection of the various voltage options is made via a
simple multi-position plug inside the unit.

The transformer feeds a conventional split full-wave bridge rectifier system.

ADDITIONAL INFORMATION

LOUDSPEAKER

LOAD

IMPEDANCE

CONSIDERATIONS

The 9130 Amplifier is suitable for use with a wide variety of loudspeaker types and load impedances.
Operation into impedances below 4 ohms is not recommended, as little additional power is available

below 4 ohms. Operation at very high power levels into low impedances for extended periods may

overheat the amplifier, but no damage will occur due to the Thermal Protection System.

In the Mono Mode, some additional consideration is required when driving low impedances. When a
stereo amplifier is converted (bridged) into a single channel mono amplifier, each half of the bridged
amplifier “sees” only half of the loudspeaker’s load impedance. For example, when driving an 8 ohm
load in the Mono Mode, each channel is actually loaded to 4 ohms. Therefore, it is not recommended

to operate the amplifier in Mono Mode into impedances below 8 ohms. It is usually better to use a stereo

amplifier of higher power rating (rather than two bridged amplifiers of lower power) when driving low
impedances.

GENERAL

TROUBLESHOOTING

If all controls, fuses, cables, etc. seem to be functioning properly, a process of one-at-a-time
is not functioning properly, a one-at-a-time reversal of interconnect and speaker cables from left to right

Ground loops are characterized by a low level hum or buzz in the system. Loops are caused by a

potential, with a single path for each ground connection. Ground loops can exist in two forms: 1) loops
created in audio interconnects, and 2) loops created between earth grounded chassis.

Mounting components to a rack with metallic rails may introduce ground loops between associated
equipment, because the rails can introduce a second ground path. The extent of this problem will
depend on the grounding arrangements of associated equipment. Ground loops can occur in non­rackmounted equipment, though it is less common.

If ground loops occur, and any other component in the system has a three wire grounded power cord,
the first step should be to use a ground adaptor (with the ground tab or wire of the adaptor not
connected) on the power cord plug of the preamplifier. DO NOT cut off the grounding pin on the plug!

It may be necessary to use additional adaptors on other grounded components if more than two
components are earth grounded. (In other words, only one earth ground per system should exist.)
Another potential source of multiple earth grounds is from coaxial antenna or cable service feeds for

FM or video sources, which usually are (and should be) earth grounded. The ground adaptor(s) should
cure this grounding problem as well.

WARNING: The use of ground adaptors (with the ground tab or wire of the adaptor discon-

nected) will eliminate the safety feature of the grounded power cord. This safety feature is

intended to reduce the risk of electric shock should an internal fault in the equipment result in

an electrically “live” chassis. Therefore, this method of ground isolation should be employed

only when absolutely necessary, rather than as a general practice. When using a ground

adaptor for isolation, make sure that the power cord plug is inserted into the receptacle in the

same orientation as if no adaptor were present, to maintain the same hot/neutral polarity.

-ll-

SPECIAL NOTE ON VIDEO CABLE “GROUNDS”: As mentioned above, the ground conductor of
cable service and antenna feeds should be connected to earth ground. Often, however, due to long

feed lengths, especially in apartment distribution systems, this ground will be of poor quality and could

be a source of noise. This interference is usually characterized by a high frequency noise, rather than
a hum or a buzz. If such interference is experienced, a separate earth ground connection should be
made from the cable outlet nearest the audio/video equipment to a known good earth ground.

If ground loops exist due to potential differences in the interconnects in rack mounted systems, then
it is advisable to isolate the preamplifier chassis from the rack rails. This may be accomplished by
sandwiching a thin sheet of insulating material (i.e., plastic washers or several layers of electrical tape,
etc.) between the rack and the preamplifier, and securing the unit with non-metallic (i.e., nylon, etc.)
hardware. It may be necessary to insulate other components so that only one component is directly
connected to the rack rails.

CLEANING/

MAINTENANCE

If the faceplate should become soiled, it may be cleaned with a slightly damp, soft cloth and, if
necessary, a mild detergent. Do not use any abrasive cleaners or solvents. Unplug the power cord
before attempting any cleaning operations.

Except as specifically detailed in the owners manual, there are no user serviceable parts or
adjustments inside the 9130 Amplifier, and all servicing should be referred to qualified, authorized
personnel.

SERVICE POLICY AND LIMITED WARRANTY

If you encounter any difficulty or have any question concerning your 9130 Amplifier, please call our

Customer Service Department weekdays, 8 a.m. to 3:30 p.m., Mountain Standard Time, at 602-967-

3565.
Should you have any doubts as to whether the amplifier is malfunctioning and requires service, please

call us before sending in for repair. All units being returned (regardless of warranty status) must receive
a Return Authorization (RA) number. In addition, we can offer troubleshooting assistance that may
simplify or even eliminate the need for factory service.

The Hafler 9130 Amplifier is warranted to the original owner (non-transferrable) for seven years from
the date of purchase, including parts, labor, and return shipping costs within the Continental United

States, Alaska, and Hawaii. This warranty applies only to products sold in the United States Of
America.

For warranties outside the U.S.A., please contact your local agent.

It is the owner’s responsibility to pay shipping (preferably United Parcel Service, UPS) to the factory:
collect shipments will not be accepted. Units under warranty should be accompanied by a copy of the
dated Bill Of Sale. Use the original carton and all packing material, with the RA number clearly marked
on the outside of the package. Be sure to include a return address, the RA number, a daytime
telephone number, and a brief description of the difficulty, including whether it occurs continuously or
intermittently.

This warranty gives you specific legal rights. You may also have other rights which vary from state to
state.
