OWNER’S MANUAL: Before powering up the equipment, read all safety and operating instructions and follow them as
instructed. Retain the safety and operating instructions for future reference.
ATTACHMENTS: Use only those attachments recommended by the unit manufacturer, as others may cause hazards.
ACCESSORIES: Do not place the unit on an unstable cart, stand, tripod, bracket, or table. The unit may fall, causing
injury to a person or damage to the unit. Mount the unit according to the manufacturer’s instructions with the
suggested mounting accessory.
WALL OR CEILING MOUNTING: Mount the unit to a wall or ceiling only in the manner recommended by the
manufacturer.
WATER AND MOISTURE: Do not use the unit near water (for example, near a swimming pool, bath tub, wash bowl,
kitchen sink, or laundry tub) or in a damp environment (like a basement or outside in the rain).
OBJECT AND LIQUID ENTRY: Do not push objects of any kind into the unit through openings as they could touch
dangerous voltage points and short-out parts, possibly resulting in a fire or electric shock. Avoid spilling liquid of any
kind on the unit. If water or any metal object (such as a paper clip, coin, or staple) accidentally falls inside the unit,
disconnect it from the AC power source immediately and contact Cary Audio Design for further instructions.
HEAT: Position the unit away from heat sources such as radiators, heat registers, stoves, or other units (including
amplifiers) that produce heat.
VENTILATION: Slots and openings in the cabinet create ventilation to protect the component from overheating. These

the unit and an opening behind the unit for airflow. Do not place the unit on a bed, sofa, rug, built- in bookcase, or
rack without adequate ventilation.
GROUNDING OR POLARIZATION: As a safety feature, the unit may be equipped with a polarized alternating
current line plug in which one blade is wider than the other. This plug will fit into the power outlet only one way. If you
cannot insert the plug fully into the outlet, try reversing the plug. If the plug still will not fit, contact a licensed
electrician to update your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
POWER SOURCES: Operate the unit only from the power source indicated on the marking label. If you are unsure of
the type of power supplied to your home, consult your unit dealer or local power company.
POWER CORD PROTECTION: Arrange power supply cords so that they do not suffer from foot traffic or pinching by
items placed on or against them. Pay close attention to cords where plug enter the AC outlet and where they exit from
the unit.
LIGHTNING: For added protection during a lightning storm or when the component is idle for long periods of time,
unplug the unit from the wall outlet and disconnect the antenna or cable system. This will help protect the unit from
lightning and power line surge damage.
POWER LINES: Do not locate an outside antenna system in the vicinity of overhead power lines or other electric light
or power circuits. When installing an outside antenna system, take extreme care to avoid touching the power lines or
circuits; contact with them could be fatal.
OVERLOADING: Do not overload wall outlets, extension cords, or integral convenience receptacles as this increases
the risk of fire or electric shock.
REPLACEMENT PARTS: When replacement parts are required, be sure the service technician has used
replacement parts specified by the manufacturer or those having the same characteristics as the original parts.
Unauthorized substitutions may result in fire, electric shock or other hazards.

FEATURES
The following section describes the HH-1’s basic features. The features are subject to change
without notice or obligation.
PRODUCT FEATURES
The new HH-1 headphone amplifier from Cary Audio is an all-new hybrid design, featuring a tube
input stage feeding a single-ended MOSFET output stage. These MOSFETs were chosen as they
have sonic characteristics very similar to tubes, and the entire amplifier operates fully in class-A at
all output levels. It is extremely simple to connect and operate, featuring a pair of RCA input jacks
and a loop-through output pair, a power switch and a volume control.
Top quality parts are mounted on a heavy gauge fiberglass circuit board, and only two stages of
amplification are used for the shortest possible signal path. A power transformer, rated at three
times what is required for the amplifier’s design, feeds a fully regulated discrete power supply for
the best sound quality. It is designed to drive headphones with an impedance between 30 and 600
ohms. A 30-second muting circuit prevents any annoying pops and clicks when turning on the HH1 headphone amplifier, and ensures that all circuits are fully stabilized before each listening
session.
All of the design and construction features would be meaningless if they didn’t contribute to both
superb sound quality and long-term reliability. Like all Cary Audio equipment, the HH-1 headphone
amplifier is engineered to provide accurate and lifelike musical reproduction, and to do so for many
years. The HH-1 has beautiful cosmetics and contains the latest technology and quality
components to ensure that you enjoy your music, whether used as a stand-alone system in an
office or as part of a serious main music system.

Warranty Card
WARRANTY CARD
IN THE USA: If you are the original purchaser of a new unit purchased from an authorized Cary
Audio dealer, please fill out the enclosed warranty registration card and return it to Cary Audio
within 15 days of your purchase. Cary Audio also suggests that you keep your original packing
cartons in case you ever need to ship the unit. Warranty restrictions apply. Consult the warranty
section at the end of this manual for details. Please be certain to keep a copy of the original sales
receipt from your direct purchase from Cary Audio or your authorized Cary Audio dealer to validate
the warranty if ever needed. The warranty is for the original purchaser only and does not transfer
to any subsequent owner.
OUTSIDE THE USA: Your local authorized Cary Audio distributor will make his own warranty
policy for your country. Please check with them for the terms of warranty for your new amplifier.
PLACEMENT
In general, the location of your new HH-1 Headphone Amplifier is not critical. Certain precautions
must be taken to ensure optimum performance. Avoid extremely hot locations such as near
radiator or other heating units. Keep the top of the HH-1 clear of books, paper or other equipment
to protect against overheating.

OPERATION
CONNECTIONS
SINGLE SOURCE
The Cary Audio HH-1 headphone amplifier is primarily intended as a single source amplifier.
•
RCA line level source (See FIGURE 1 & 2 below).
Connect the line level RCA audio outputs of a CD player or other line level source to the
inputs of the HH-1 headphone for output. This Should ONLY be done using the source’s
fixed output. It is NOT recommended to use a source’s variable output. Doing so could
accidently result in supplying too much gain to the input of the HH-1 headphone amplifier
whereby causing damage to it and/or any connected headphones.
MULTIPLE SOURCES
There are a couple of ways to connect the Cary Audio HH-1 headphone amplifier for listening to
multiple sources.
•
Preamplifier of a Main Audio System (See FIGURE 3 below).
To do this, your main system preamplifier must have a set of line level RCA Record (Tape)
outputs. Do NOT use a standard set of variable preamplifier outputs as this could result in
damage to the HH-1 headphone amplifier and or connected headphones.
By connecting this output (tape output) to the input of the HH-1, any source you have
selected on the preamplifiers record or tape output will be outputted to the input of the
HH-1. This type of output is typically a fixed output whereby eliminating the need to use
the main system preamplifier volume control. To control the volume you only need to use
the volume control of the HH-1 headphone amplifier.
•
Digital to Analog Converter (See FIGURE 4 below).
Connecting the line level RCA analog output of a digital to analog converter to the RCA
input on the HH-1 headphone amplifier can allow for multiple source listening, depending
on the capabilities of the DAC. By simply changing the selected source of the DAC will
change the source sent to the input on the HH-1.
•
Separate Analog Source Selector or Headphone Preamplifier: Usually a part of a
dedicated headphone listening system. (See FIGURE 4 below).
Connecting such a device in front of the HH-1 will allow for switching of multiple connected
sources. To do this, connect the source selector or headphone preamplifier line level RCA
output to the RCA input of the HH-1. Simply changing sources on the analog source
selector or headphone preamplifier will facilitate multiple source listening.
10
OPERATION
OUTPUT
The HH-1 headphone amplifier is designed with a single pair of FIXED line level RCA outputs. The
purpose of this fixed output is to send the signal of the HH-1 headphone amplifier to either a
preamplifier or an integrated amplifier. It is NOT intended to be connected to the input of a power
amplifier.
CAUTION:
• Connecting the RCA output of the HH-1 amplifier directly to a power amplifier’s input
may result in damage to the power amplifier and/or connected speakers.

14
SERVICE AND CARE
TUBE REPLACEMENT
The Cary Audio HH-1 Headphone Amplifier’s tube circuit is designed to offer several years of
performance under normal listening conditions. Please bear in mind that tube degradation is a
slow and subtle process over time. As such, after several years of enjoyment one may not notice
any significant difference in performance. Therefore, we recommend regularly scheduling tube
replacement every two to three years or sooner if usage is heavy. Please follow the procedures
below or contact Cary Audio service for an RMA at 919-355-0010.
•
Tube Replacement Procedure:
o Disconnect any attached connectors (headphones, AC power cord, and audio
cables) from the unit.
o Remove screws holding top cover.
o Remove tubes and replace them with the correct replacement tube (6922 or
6DJ8) being sure the pins are inserted correctly and the tubes are fully seated.
o Take care in handling the tubes properly minimizing any direct contact with
your fingers. A soft, lint free glove or cloth works best.
o Replace top cover and reinstall screws.
CAUTION:
• ALWAYS disconnect the unit from the AC outlet and power cord.
