Safety Cautions
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR
BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO
QUALIFIED SERVICE PERSONNEL.
Warning: Non-insulated dangerous voltage within the product,s enclosure
may be of sufficient magnitude to constitute a risk of electric shock.
Important operating and maintenance instructions in this user guide.
Warning: To avoid fire or shock hazard, this product should not be exposed
to rain or other moisture.
To completely cut off the power, the electrical plug should be unplugged.
DO NOT TOUCH the vacuum tubes once turned off as they will remain hot
for some time. The radiator on the amplifier may also get very hot in use, do
not touch when operating, cover or obstruct the air flow around it.
RISK OF ELECTRIC SHOCK
DO NOT OPEN
WARNING
01

Please read instructions carefully. Store and retain the operations guide for future reference.
Pay attention to all warning information and operate in accordance with the instructions.
Avoid high ambient temperature use. Do not operate the amplifier in a room temperature over
40℃ or 104℉. Please allow the heat to fully dissipate after use.
Grasp the plug firmly when the power cable is being unplugged. Do not pull the cable to unplug.
This product should not be placed in a dusty, dirty environment or be exposed to very high
humidity (sauna, bathroom etc.)
The plug should be unplugged if the product will not be used for a long time.
Air ventilation should not be blocked or obstructed.
Nothing should be dropped into the amplifier. This could cause damage, especially to the fragile
tubes on top.
Do not expose the product to chemicals such as pesticides, benzene, acids or alkaline.
This product should not be disassembled or refitted by anyone other than HIFIMAN.
To avoid fire, while the amplifier is working, vacuum tubes and air vents should not be
obstructed with papers, tablecloth, curtains or any other items.
Open flames such as candles should not be placed on or near the amplifier.
Highly flammable, liquids should not be dropped or sprayed on the amplifier.
To avoid fire hazard, items containing liquids such as vases or glasses should not be placed on
the amplifier.
Do no operate with wet or oily hands.
There is high output on the output terminal of front panel of the amplifier.
To avoid shock hazard, nothing should be inserted in the output port of the
amplifier except a suitable headphone jack.
The power cable should not be trampled on or be a trip hazard.
Accessories and spare parts used should be specified by HIFIMAN only.

Safety Cautions

Headphone
To avoid risk of electric shock and to protect the diaphragm from being damaged, nothing
should be inserted into the grill on the headphone.
As with the amplifier, the headphone should be kept away from a high temperature environ-
ment ( ambient temperature should not exceed 40℃ or 104℉. )
Keep the headphone away from substances such as alcohol, gasoline, acetone, other solvents,
sulfuric acid, sodium hydroxide or any other corrosive substances.
Do not treat the headphone violently as this may cause permanent damage to the internal
structure and invalidate the warranty.
If the headphone should get wet, do not use a heat gun or hairdryer on the product as this
could permanently damage the headphone's diaphragm. Allow to dry naturally in a warm but
dry environment such as an airing cupboard.
Do not use the headphone with wet hair.
If the product is to be left unused for a long time, please keep in the storage box and seal with
a moisture-proofing agent to prevent mold or corrosion.

Nano-particle coated sub-micrometer thickness diaphragm provides unsurpassed
high frequency response.
The highly resolving audio and extremely high frequency range allows the sound-
stage to be dramatically open and expansive compared to a traditional “moving
coil”type headphone.
Metal mesh stators working in proximity to the ultra-thin diaphragm provide
superior openness and less distortion than other headphones.
Nanometer grade dust cover helps prevent dust and other pollutants settling and
avoiding ensuing distortion caused by electrostatic dust.
Lightweight (only 13.2oz or 374g) and ergonomic design provides superb comfort
for extending listening.
Sturdy and durable, the outer covering is made of 6-series aluminum alloy with an
anodized finish.

Features

Please read the following instructions before connecting this product to a power source for the
first time. Power voltage might vary in different countries and areas.
Please make sure the rated voltage ( for instance, alternating current AC 230V 50Hz or alternat-
ing current AC 115V 60Hz ) on the panel corresponds to local mains voltage. If not, the power
supply should be turned off and the power cable should be disconnected, adjust the voltage
selector with a flat head screwdriver. Make sure the power supply corresponds to the local mains
voltage before reconnecting.

Functions

Initial Setup
12
Open the package box, remove the amplifier and power cable carefully.
Put the device on a stable surface, then remove the protective film from the top panel.
Open the box, remove the vacuum tubes, headphone stand, headphone (separately
packed) .
Take out the tubes carefully. Arrange the tubes in order according to the markings on
them.
Vacuum tube matching has been carried out when manufactured for optimum working
status. For convenience during installation, please use the tubes in accordance with their
numbers.
The tubes have been marked A1~A4(6SN7). Please insert according to Figure 2 as below.
Note: The base on the 6SN7 should be inserted precisely into the tube socket. (Figure 1)
To install: Grasp the tube base, insert gently into the tube socket until it reaches the bottom
of the socket.

Two pairs of electrostatic headphones can be connected to the
amplifier and operated at the same time.
Insert 5-PIN headphone
plug into output port of
amplifier (point the plug
to upward side)

Basic Operation
15
When the "POWER" switch on the front panel is pushed on, the red LED on the front
panel blinks for 30 seconds. When the LED lights up continuously, the unit is ready to
operate.
Plug the headphone into one of the sockets on the front panel.
Select the connected input signal using the“INPUT”selector switch beside the input
connector.
Turn the volume potentiometer clockwise to set optimal volume level. Output sound
level can be read from indicators around the knob.
Press the switch to select the Balanced Input source.
Press the switch again (the switch will reset) to select the AUX Input source.

The Bias Adjustment
16
Turn on the amplifier for 10-20 minutes.
Set the volume to 0 and disconnect headphones and audio inputs.
Connect TP5 with the black probe of a multimeter and measure the DC voltage of the TP1-TP4
terminals in turn. It should read between 5-10V. If the deviation is too large, please adjust the
potentiometer TP1, and then repeat for TP2 – TP4 until the voltage to ground is equal.
Once completed, please wait 10 minutes and test each channel again to ensure voltage stability.
Place the cover back onto the amplifier and turn off the power. You may then reconnect the
audio inputs and the headphones.
* Should you find anything unusual or are not able to replace/adjust the 6SN7 tubes, please
contact your local distributor or HIFIMAN customer service.
