WHAT’S IN THE BOX?
In addition to the Integrated 1, it’s cover, and the oper-
ating manual you are presently reading (with associated
inserts and warranty card), there are a few more items to
take inventory of before steps are taken to make the
Anthem Integrated 1 operational.
These items are:
• 4 12AU7 tubes (2 matched pairs)*
• 1 12AT7 tube
• 8 EL84 tubes*
• a glove for handling the tubes
• a detachable AC power cord
• a handful of phillips screws
• a phillips screwdriver
After completing an inventory of these items, proceed
to the next steps.
*These tubes are carefully measured and matched in
pairs and octets. Take extra care to keep them from
being mixed and mismatched which would degrade
performance.

A SELECTOR SWITCH
This knob is rotated to select a Line Level Input (L) or
the optional Phono Input (O). The Selector Switch is
bypassed when the Tape/EPL (External Processor
Loop) mode is selected by depressing the Tape/EPL-
Source button (D).
B BALANCE CONTROL
This knob controls the relative balance of the left and
right channels to compensate for any discrepancies
caused by speaker placement, source imbalance, etc.
Full rotation to the left or right of the center detent will
have a ±6dB trim on levels between left and right
channels.
C VOLUME CONTROL
This knob allows variable control over the Integrated 1
output level. Turn it clockwise and the music gets louder!
D TAPE/EPL(EXTERNAL PROCESSOR LOOP)-
SOURCE BUTTON
When this button is in the SOURCE position (button is
not depressed) the signal is routed through the
Selector Switch (A) to the Tape/EPL Output (K) con-
nected with a tape deck or external processor such as
a surround sound decoder. Listening and taping is
done in this mode. When the button is depressed, the
source signal is taken from a tape or processor source
through the Tape/EPL Inputs (N) bypassing the selec-
tor switch.
EL E D
When the LED is lighted the Integrated 1 is “ON”,
receiving power from the power supply.
FM U T E - O P E R ATE BUTTON
When in the OPERATE position (not depressed), this
button will allow normal function. When in the MUTE
position (button depressed), the music signal is cut off
from reaching the Outputs (I,J,).
G ON-OFF BUTTON
When in the ON position (button depressed), high volt-
age power is received by the Integrated 1 circuitry
from the power source. Due to the warm up charac-
teristics of tubes, it will take 30 seconds for the tubes
to pass full signal. It is suggested that the Integrated 1
remain muted or the Volume turned down for this first
minute. When in the OFF position (not depressed), the
Integrated 1 is not receiving power and is not opera-
tional.

HD E TACHABLE AC POWER CORD SOCKET
Plug the Detachable Power Cord into this socket (see
Figure 2). The Integrated 1 is factory set for the correct
operating voltage for the area in which it is sold (see
shipping box for voltage setting). If a different operat-
ing voltage is required, please contact an authorized
Sonic Frontiers or Anthem dealer, distributor or the
factory directly.
I SPEAKER CONNECTION POSTS
These 5 way binding posts accept a connection from
one pair of speakers. The negative connections are to
be made to the black connectors; left speaker to the
terminals marked left and right to the terminal marked
right. The positive connections are determined by the
speakers. If the speakers impedance tends towards
an 8 ohm load, use the left and right positive (red)
posts labeled as 8 ohm. If the speakers are better
represented by a 4 ohm load impedance, use the pos-
itive connectors labeled 4 ohm. Consult your speaker
specification sheet, manual or manufacturer directly if
there is any clarification needed regarding the imped-
ance of your speakers. NOTE: ONLY ONE PAIR OF
POSITIVECONNECTORS MAYBE USED AT A TIME.
UN D ERN O CIRCUMSTANCES ARE TWO PAIR OF
SPEAKERSTO BE CONNECTED TO BOTH 4 OHM AND
8OHM POSTS.
Refer to Figure 2 for further instruction.
J PREAMPLIFIER OUTPUT
This output connects to the single-ended inputs of
other units such as power amplifiers or a crossover
unit; connect left channel to left channel and right
channel to right channel. The set allows the Integrated
to be used solely as a preamp. For the Preamplifier
Outputs to function, an internal jumper connect-
ing the RCA Preamplifier Outputs and Power
Amplifier Inputs must be cut or de-soldered.
See Figure 1.
K TAPE/EPL (EXTERNAL PROCESSOR LOOP) OUTPUT
This output connects to the single-ended inputs of a
tape deck or external processor; connect left channel
to left channel and right channel to right channel. This
output always follows the input selection of the
Selector Switch (A).
LLINE LEVEL INPUTS FOR CD, TUNER
AND AUXILIARY SOURCES
A line level single-ended source connection may be
made to these 4 sets of RCA connectors; connect
left channel to left channel and right channel to right
channel.
M POWER AMPLIFIER INPUT
This input accepts a single-ended RCA input connec-
tion from an external preamp or crossover; connect
left channel to left channel and right channel to right
channel. The signal input at these connections will
bypass all control functions and preamp functions of
the Integrated 1 and will operate only as a power
amplifier. For the Power Inputs to function, an
internal jumper connecting the RCA P reampli f ier
Outputs and Power Amplifier Inputs must be cut
or de-soldered. See Figure 1.
N TAPE/EPL INPUT
This input accepts a single-ended RCA input connec-
tion from a tape deck or external processor; connect
left channel to left channel and right channel to right
channel. These inputs are activated when the
Tape/EPL-Source button (D) is depressed.
CONNECTION FUNCTIONS
NOTE: The Integrated 1 is shipped in the “integrated amplifier” configuration. For use as a separate “preamplifier”
and/or “power amplifier”, refer to Figure 1 and points J and M for instructions.

O OPTIONAL PHONO INPUT
AND GROUND CONNECTION
This input is designed to replace the AUX 2 line level
input when the optional phono input module is
installed. This extra amplification stage provides addi-
tional gain when dealing with sensitive signals from
moving magnet phono cartridges. Connections are
made from a turntable; left channel to left channel and
right channel to right channel. The turntable’s ground
wire should connect to the ground post at the center
of the RCA inputs to prevent any “hum” from interfer-
ing with the signal. See the separate instruction sheet
that comes with this optional stage for more informa-
tion. If your Integrated 1 was not purchased with a
phono stage and you wish to order one, contact your
dealer or Sonic Frontiers directly.
DO NOT CONNECT A LINE LEVEL SOURCE TO THE
PHONO INPUT IF THE OPTIONAL PHONO INPUT IS
INSTALLED. DOING SO MAY OVERLOAD AND
DESTROY THE SENSITIVE CIRCUITRY. THIS DAMAGE
WOULD NOT BE COVERED UNDER YOUR WARRANTY.

S E T T I N G U P
The Integrated 1 comes with thirteen (13) tubes, as follows:
12AU7 (LV1 & V1) PREAMP TUBES
These tubes perform the line level preamplifying function of
the Integrated 1. The preamplifier stage of the Integrated 1
provides 12 db of gain. The 12AU7 tubes may be replaced
with matched pairs of ECC82, E82CC, ECC802S, 5814A,
6189, CV4003 or M8136.

1 2 AT7 (V3) FIRST STAGE AMPLIFICATION TUBE
The first stage of amplification in the amplifier section of
the Integrated 1 is achieved through the use of this dual
triode, amplifying both channels, one per triode section.
The 12AT7 may be replaced with the ECC81, E81CC,
ECC801S, 6201, CV4024or M8162 tube.
12AU7 (LV2 & V2) DRIVER TUBES
These tubes split the phase of the signal and drive the
push/pull pairs of power tubes. The 12AU7 tubes may be
replaced with matched pairs of ECC82, E82CC, ECC802S,
5814A, 6189, CV4003 or M8136.
EL84 (LV4,5,6,7 & V4,5,6,7) POWER TUBES
These tubes provide the last stage of amplification, set up
in push/pull pairs (4 tubes per channel, two per phase).
The EL84 tubes use a non-adjustable fixed biasing
scheme - meaning these power tubes do not require
manual bias adjustment by the user. If one EL84 should
fail, the entire channel (V4 through V7 or LV4 through LV7)
should be replaced with a matched quad set for best per-
formance. The EL84 may be replaced with the EL84M,
6BQ5 or 7189 power pentode tube.
The entire power amplifier section (First Stage to Power
Stage) provides an additional 28 db of gain.

INSERTION OF THE TUBES
1. Using the screwdriver supplied, remove the cover of
the Integrated 1. For your convenience, only two of the
screws are installed at the factory.
2. When handling the tubes, it is recommended that the
cotton gloves provided be worn to prevent skin oils from
depositing on the glass surface and possibly causing the
tube to become prematurely “gassy”, thereby shortening
the tube’s useful operating life.
3. Noting the location of the tube sockets in the top view
photo, inspect the tubes for corresponding labels and
markings. Once locations are mapped, take a tube and
inspect the pins, noting the larger space between two of
the pins (see Figure 3). This space will match with the
socket. Insert each tube into the appropriate tube sock-
et, making sure all pins and pin holes are aligned. Do not
force the tubes into the sockets. “Rock” the tubes gently
while pushing slowly until each tube is firmly seated.
O P E R A T I O N
Before plugging in the Integrated 1, check to see that the
unit is configured for the correct AC line voltage for coun-
try of use. The operating AC line voltage is indicated on
the side of the shipping box. If the Integrated 1 is set
incorrectly for the country in which it is to be operated,
contact the dealer or distributor in your area. If the unit is
configured properly, continue with operation.
Connect the Detachable Power Cord to the Integrated 1
AC Power Cord Socket (H) (see Figure 4). Plug your
Integrated 1 into the AC power source.
All remaining connections are made with co-axial cable
and RCA connectors to or from other single-ended units.
Connect source units to the Integrated 1 Inputs (L); l e f t
channel to left channel and right channel to right channel.
If a tape or other line level recording or processing device
is being implemented, connect the left and right audio out-
put of the unit to the corresponding left and right Tape/
EPL Input (N) of the Integrated 1. Also connect the left and
right Tape/EPL Outputs (K) on the Integrated 1 to the cor-
responding left and right audio inputs of the external
device.
Connect loudspeakers to the appropriate post as
described in the connection section of this manual.
The Integrated 1 is now ready for operation. Power the
Integrated 1 by placing the On-Off button (G) in the ON
position. The tubes will take approximately 30 seconds to
warm up and then the Integrated 1 is functional.
Select a ready source through the Selector Switch (A).
Balance is adjusted through use of the Balance Control (B);
turning it left and right will adjust the left and right levels
respectively in a -6dB adjustment range. The center detent
is an indicator for equal, or balanced, left and right levels.
Volume is adjusted through use of the Volume Control (C).
Turning this control clockwise increases the volume level
of both channels. Be sure the level is sufficiently low when
turning the unit ON or returning to the OPERATE mode
after MUTING, to prevent damage to speakers, amplifiers
Note the larger space
between two of the pins and
holes for proper alignment
of tube and socket.

or the Integrated 1.
To record from a source, place the Tape/EPL-Source but-
ton (D) in the SOURCE position, select the source material
you wish to record via the Selector Switch (A), and com-
mence recording. To play back a tape recording, place the
Tape EPL/ Source button in the TAPE position.
Muting the Integrated 1 is achieved by placing the
Mute/Operate button (G) in the MUTE position (button
depressed); the output signal is then cut off. To resume
listening, place the button in the OPERATE position (not
depressed).
T R O U B L E S H O O T I N G
If at any time the Integrated 1 fails to work properly, consult
this checklist:
1. Check that the AC Detachable Power Cord is plugged into
the Integrated 1 Detachable Power Cord Socket (H) and is
connected to a live source of AC power. For instance, if using
a power bar, check that the bar is turned on.
2. Ensure that all Input and Output connections are secure for
a proper electrical contact.
3. DISCONNECT THE AC POWER CORD, wait 5 minutes,
remove the chassis covers from the Integrated 1 and Power
Supply and check that:
• A slo-blo fuse, with a rating of 2.5 Amp/250 V (1.25
Amp/250 V for European and Asian versions), is installed in
the cylindrical tube next to the large power transformer.
• The AC power fuse is intact and has not blown. If the fuse
has blown, the thin metal conductor will have melted and the
glass may appear “smoked”. If the fuse has blown, replace
with a fuse of the same rating (2.5 Amp/250V slo-blo for 100
to 120 volt countries and 1.25 Amp/250V slo-blo for 200 to
240 volt countries). (See Figure 5)
NOTE: Under no circumstances should you replace the AC
power fuse with one of a higher current rating! Doing so may
cause further damage to the Integrated 1 and will also void
the warranty. In addition, your continued protection from risk
of fire or shock would be seriously compromised.
• Ensure the tubes are plugged firmly into their sockets as
described in “INSERTION OF THE TUBES”.
5. Be sure the rest of the system is functioning properly (i.e.
source unit, power amplifiers, cables and connections, etc.).
6. With tubes, fuses, covers and power cords in place, check
that the LED (E) is lighted (glowing light green). If all of the
above troubleshooting steps have been followed and the LED
is not lighted (remains dark green), contact your dealer or
distributor for assistance.

BREAK-IN TIME
As with all audio electronic products, the ultimate sonic
character of the Integrated 1 will not be realized until and
unless the unit receives a minimum of approximately 70
hours of signal break-in time (i.e. the Integrated 1 is on
and outputting a signal).
PLACEMENT FOR PROPER VENTILAT I O N
Allow at least 4” (15 cm) of clear space above the
Integrated 1 chassis for proper ventilation, making sure the
air vent slots in the chassis cover remain unobstructed.
Also, be sure that the Integrated 1 is placed on a secure,
hard and level surface (not on carpet).
SAFETY INSTRUCTIONS
1. Ventilation - Although your Integrated 1 generates only nomi-
nal heat in use, be sure that the ventilation slots in the top
cover have at least 4” of unobstructed air space above them.
2. Water and Moisture - This product should not be used
near water. To prevent fire or shock hazard, do not expose
this product to rain or moisture.
