Ready to Rumble! - A Quick Look at the Bijou 600
AudioControl’s Bijou 600 is in a new class of compact, high-powered
ampliers with a built-in audiophile-grade DAC designed specically
to provide greater performance and higher sound quality for all ana-
log and digital systems, including streaming audio components like
Sonos® home entertainment.
The Bijou 600’s powerful amplier delivers 100 Watts of power
per channel into 8 Ohms and 200 Watts per channel into 4 Ohms.
Additionally, the Bijou 600 can be bridged to perform as a 400 Watt
mono-block amplier.
The state of the art Bijou 600 features a built-in high-performance
Wolfson® DAC (digital to analog converter) that dramatically improves
audio quality and performance.
Digital and analog audio-systems can now reach their full potential
across the whole house whether the speakers are free-standing, in-
wall, in-ceiling, invisible, desktop, gaming, in the garden shed etc.
Equipped with AudioControl’s unique patent-pending AccuBASS™
circuitry, the Bijou 600 also rejuvenates the bass response lost in most
digital compression schemes. This results in a richer and fuller audio
performance with better bass and mid-bass response.
Chapter 1: Introduction
In addition, the Bijou 600 acts as a pre-amplier allowing for volume
control, AccuBASS™ and input selection to be eortlessly controlled
from its own RTR-1 Remote Control, from a third-party control system
or another Remote Control.
The net eect is that you will enjoy a more complete listening experi-
ence and hear music with a richness and vibrancy much closer to the
way the artist intended their music to be enjoyed.
We thought that you might be interested to know
that the Bijou 600 won a Consumer Electronics
Association Mark of Excellence Award! It was chosen
by a panel of industry experts for excellence in cus-
tom integration and installed technology as Audio
Product of the Year.

The Bijou 600 has been designed to equalize
and improve the performance of all speaker
set-ups. The power of the amplier combined
with the audio performance and quality of
AudioControl’s Wolfson-engineered, digital to
analog converter (DAC) results in a dramatic
improvement in the performance of all speak-
er set-ups throughout the house.
Shown on the right are just two of the many
types of speaker congurations that the Bijou
600 can work with. The 4.1 speaker set-up
takes advantage of the Bijou 600 amplier’s
stability at 4 Ohms powering four speakers.
In addition, the Bijou 600 can be used as an
incredible Mono amplier with power ratings
up to 400 Watts (see next page).
In both systems shown, the 80 Hz HP lter
allows the main speakers to play the range
above 80 Hz, and the 80 Hz LP lter sends the
frequency range below 80 Hz to a powered
subwoofer. This takes the strain o your main
speakers if they can’t reproduce the low
frequency range, and it conserves amplier
power.
2.1 Speaker
Set-up
The standard set-up for a 2.1
speaker system with two 4 or
8 Ohm speakers plus a pow-
ered subwoofer.
4.1 Speaker
Set Up
The standard set-up where
four 8 Ohm speakers are con-
nected in parallel to form a 4
Ohm load per channel. (The
minimum speaker imped-
ance for this conguration is
8 Ohms.)

Bridged Mono and Powered Subwoofer Speaker Setup
Chapter 3: Hookup Diagrams
This system shows two Bijou 600 ampliers
used in bridged mono mode to produce
400 Watts per speaker into 8 Ohms. A pow-
ered subwoofer is also shown. The Bijou 600
crossover is used to reduce the bass playing in
the main speakers (80 Hz HP) and let it play in
the powered subwoofer instead (80 Hz LP).
The rst Bijou 600 is the Master unit
where all source connections and volume
adjustments are made. The second Bijou
600 is the Link unit, and receives the right
channel analog line-level signals from the
Master unit.

Installation
The Bijou 600 is a compact yet high performance amplier and audio-
phile DAC. As such, it delivers incredible sound performance.
• Care should be taken in finding the best location to place the
unit for optimal performance.
• The Bijou 600 loves speakers and can be situated to fit in with
any speaker set up from the most powerful free-standing speak-
ers to the smallest desktop conguration.
• As with all products made in the USA by AudioControl, the Bijou
600 should not be deep fried or sautéed!
Placement
This may be as good a time as any to have“the talk” about ventilation.
The Bijou 600 features cool-running ecient switch mode power
supplies and Class D amplifiers. It is still an amplier, and therefore
requires good ventilation to cool.
• Place the Bijou 600 on a level, firm surface, avoiding direct sun-
light and sources of heat and damp.
• Do not place the Bijou 600 on top of another power amplifier or
other source of heat.
• Do not place the Bijou 600 in an enclosed space such as a book-
case or closed cabinet unless there is good provision for ventila-
tion. The Bijou 600 will run warm during normal operation.
Chapter 4: Installation
• Do not obstruct the ventilation vents on the top panel, back, or
sides of the unit. “It likes to breathe.”
• Do not place the unit on carpeting, a large sleeping dog or any
thick material that could block the vents.
Optional Accessories
The Bijou 600 has various optional accessories available that allow it
to be installed in a standard 1U rack, surface mounted, in a wall-box,
or on the back of a TV. See page 34 for more details.
RM-209 single rack mount kit - allows one Bijou 600 to be rack
mounted (1U, 19 inches wide).
RM-210 dual rack mount kit - allows two Bijou 600s to be rack
mounted (1U, 19 inches wide).
RM-211 mounting brackets - two L-brackets allow a Bijou 600
to be wall or surface mounted, or used with the RM212 in-wall
box, or RM213 component mount plate.
RM-212 in-wall back box - allows a Bijou 600 to be in-wall
mounted. It also requires an RM211 mounting bracket kit.
RM-213 component mount plate - allows a Bijou 600 to be
mounted vertically to the back of a TV monitor. It also requires an
RM211 mounting bracket kit.

Installation Manual
Chapter 4: Installation
Cables
We recommend the use of high-quality analog and/or digital cables.
All cables should be kept as short as practically possible. Power ca-
bling should be kept as far away as possible from audio cables.
Speakers
The Bijou 600 is designed to work with all 8 Ohm and 4 Ohm speak-
er setups. The Bijou 600 is versatile and flexible and works with the
following speaker installations and more!
• Free-standing speakers
• Invisible speakers – in-wall and in-ceiling
• Extra zone speakers including outdoor
• Televisions and sound bars
• Desktop speakers and gaming speakers
And more……. The Bijou 600 loves speakers and speakers love the
Bijou 600! See the next page for more speaker details.
Note: Do not use the Bijou 600 in systems that are
“common-grounded,” where the negative left and negative right
speaker terminals are joined together.

15
Speaker Connections
Establish a standard connection color code and stick with it. One
conductor of the speaker wire is normally marked by a dierent color
(silver versus copper) or there is ribbing on one side. Typically this
marked conductor is used for the positive (+) speaker leads. Really
good wire has Positive and Negative printed right onto the wire
jacket.
Match the polarity markings on the unit with the polarity markings
on your speakers.
Speaker and Wiring Impedance
Speakers, like other resistors, if wired in parallel“show” lower values
than the individual components. The important thing is to make sure
your speakers are 4 Ohms or greater per channel in stereo or 8 Ohms
or greater when connected in bridged mono mode.
Hereis an example for calculating speakers wired in parallel:
Calculating Impedance
For two 8 Ohm speakers wired in parallel (pluses connected to
pluses) the impedance is 1/8 + 1/8 = 2/8
Then take the inverse or 8/2 = 4 Ω
Often the real world is more complicated than theory, and for speak-
ers this is the case. An 8 Ohm speaker is not 8 Ohms at all frequencies.
Plus passive crossover networks add their own changing conditions.
Be aware of speakers that have signicant dips from“nominal” values
in portions of their frequency range, and speakers that are rated at
unusual impedances, for example 3.5 Ohms. The Bijou 600 is tolerant
of impedance loads down to 4 Ohms, however, all good designs use
some margin of error.
Your choice of speaker wire gauge and the length of the runs, also
aects the speaker impedance load presented to the ampliers. Even
fairly short speaker runs can have signicant resistance if you use a
smaller wire gauge. The downside of this wire resistance is that you
waste some part of the total power available to the speakers.

5. Power Switch – In the OFF position, the AC line voltage is
disconnected from all internal circuits, and no amount of
remote control pressing, input signals playing, RS232 com-
munications, telepathy, or loud yelling will turn it back on. Turn o
the power switch when you are not using the amplier for long
periods of time, such as a nice two-week vacation to a golden
sandy beach somewhere (sigh), or during lightning storms, elec-
trical power outages, or zombie apocalypse. Keep the amplier
turned o when making connections or when disconnecting.
The Bijou 600 can also be used in the ON position, where it will be
a lot more useful and fun. Do not turn it on until all connections
have been made, and you are sure the voltage selection switch is
set to the correct local AC voltage.
6. Voltage Selection Switch – This slide switch allows you to
set the amplier to your local AC voltage. Always make sure
it is in the correct position before connecting the AC power
cord, as the incorrect setting will damage the amplier.
7. AC Input – This is where you connect the supplied AC
power cord. First make sure that the power switch is o,
and the voltage selection switch is in the correct position,
and then push in the power connector rmly to make a
secure connection.

SLEEP DEFEAT - This prevents the Bijou 600 from automatically
going into standby mode, and defeats signal-sensing. Obeys IR
and RS232 commands, and the front panel blue LED will remain
blue constantly indicating normal operation. For optimal energy
savings, this switch should be left in the up (O) position and
the Bijou 600 will detect signal on any of the three inputs and
turn on automatically. If no signal is present, the unit will go into
standby after 8 minutes.
DIGITAL 2 VOLUME DEFEAT - This switch should
be engaged when it is desirable to control the
volume of channel 2 from an external source only,
such as the volume control on an iPod, tablet etc.
Only the volume control is defeated.

See note in BRIDGED
80Hz HP – Internally applies a 80 Hz high pass signal to the
left and right speaker-level outputs. Normally used when
employing a separate subwoofer where the Bijou 600 plays just
the 80 Hz high-pass frequency range in the main speakers. Ideal
for sound-bars and subwoofers. The green high pass LED on the
rear panel will light when this switch is engaged.
ANALOG 3 VOLUME DEFEAT – This switch
should be engaged when it is desirable to control
the volume of channel 3 from an external source
only, such as the volume control on an iPod, tab-
let etc. Only the volume control is defeated.
*
See note in BRIDGED
80Hz LP – Changes the sub/mono output from a full-range
summed mono left/right signal to a summed mono 80 Hz, 18 dB
per octave, low pass signal. Normally used if a subwoofer does
not have a built in crossover. The green low pass LED on the rear
panel will light when this switch is engaged.
HIGH GAIN – When this is engaged, the Bijou 600
provides an additional 10dB of gain for use with
Analog input 3. This helps analog sources with
very low signal output to operate optimally when
playing back music with quiet passages. This
switch should not be engaged when the Bijou
600 is being used as a ‘Link Amplier’.
BRIDGED – Internally routes the left signal of the selected chan-
nel to the speaker outputs, and the right signal of the selected
channel to the bridged mono output. The green bridged LED on
the rear panel will light when this switch is engaged.
*
Note: For a Bijou 600 to be used as a Link unit, set the 3
volume defeat switches and the bridged switch all ON. In this
way, the Link unit is not aected by the remote control. It will
only aect the Master unit.

Installation Manual
Chapter 5: Features
10. Speaker Connector – This is where joy meets world: the speak-
er-level output of the amplier connects to the wiring of your
speakers. The connection is made using the supplied push-on
4-pin Euroblock connector. Make a note of the polarity markings
and make sure they match those of your speakers (positive to
positive or red speaker terminal, negative to negative or black
speaker terminal). If wired incorrectly, then there will be phase
cancellation and disappointing bass performance.
11. Crossover and Bridged LEDs – These three LEDs are on whenev-
er the relevant DIP switches are ON (down). They will help remind
you whenever the HP or LP crossover are on, or that the amplier
is in bridged mono operation. They can all be on at the same time.
In the night, they secretly communicate your recent playlist with
the Altair star system (marketing research department).

12. IR In and IR Out – These 1/8” connectors allow the use of wired
Infrared (IR) remote control systems, such as external IR transmit-
ters, controllers, repeaters and receivers. These external systems
are useful in situations where the Bijou 600 is mounted out of the
RTR-1 remote control’s line-of-sight.
13. Sub/Mono Out – This RCA line-level output is most often used to
send a mono output to feed either a powered subwoofer or a sub-
woofer amplier/passive subwoofer combination. The output is a
line-level gently-mono mix of the left and right currently-selected
input, and it is aected by the volume level, AccuBass level, and
the 80 Hz LP crossover. This output is o when headphones are
used.
