Introduction
I am very pleased that through a sea of quality audio equipment you have chosen
a BSC product. All the devices we make come from a deep yearning to provide a
perfect vehicle for the creation of a meaningful listening experience. When you
purchase a BSC product you also acquire a piece of my soul, inspiration, and DNA.
My dream has always been to create products that not only bring the listener great
pleasure but to that end grant a deeper understanding and insight into the artist’s
vision. For the rst time in my professional career I was unburdened by another’s
vision and nally able to translate decades of experience into a line of products that
are truly inspired.
BSC hand builds all of it’s products in small quantities to maintain the very highest
quality control standards. Units are subjected to rigorous test standards and leave
our factory a beacon of quality.
In a world of corporate consolidation, it is hard to know who actually is responsible
for designing the products we buy, and where they come from. At BSC not only do
you have a product designed to a singular vision but you also have access to the
designer himself at virtually anytime.
Thank you for your purchase,
Bret D’Agostino

Unpacking and Placement
NOTICE: BSC ampliers are extremely heavy, it is recommended that two people aid in the
unpacking and installation of our products.
Unpacking
1. Place the amplier box on a rm level surface with plenty of room to move around it.
2. Cut the tape from the top of the box carefully, do not stick sharp cutting devices too deep
into the cardboard as you may damage something located at the surface of the package.
3. Remove the Top White Cap from the Outside box. The amplier is now exposed, covered by
a special vinyl cling wrap.
4. Facing the front of the amplier (curved portion) there are handles located on the left and
right side of the unit attached to a special cardboard carrier. With a person on each side reach
down and grab the handles, each person pulling the amplier upward and free from the bot-
tom carton, then walking forward or backward to a free space.
5. The amplier is now free to move to it’s nal location. Remove the vinyl wrap from the unit
before you apply power.

Placement
Ventilation: BSC 5-Series ampliers are class A designs and can get very hot over the top
cover vents. Because of this they should be placed in an area where adequate ventilation is
available. At least 8-10 inches of space over the top cover and 2 inches on either side is rec-
ommended. There should be no obstruction above or below the amplier allowing cool air to
circulate from the bottom upward through the amplier chassis and out of the top cover vents.
NOTICE: The top cover vents should never be covered or obstructed.
Location: 5-Series ampliers can be placed on a oor or inside of an open cabinet. For addi-
tional cooling and vibration reduction an amplier stand can be utilized. Please verify the fur-
niture will be suitable based on the heat and weight requirements of the amplier. It is recom-
mended the amplier be placed as close to the loudspeaker location as possible. This with the
use of minimum length speaker cable will maximize the power transfer to the loudspeaker and
ensure best performance.
CAUTION: Never place the amplier in or around open or running water sources.

Associated Equipment
The BSC 5-Series ampliers are extremely high performance and designed to enhance the
listening experience. It is recommended that associated components be chosen that can best
take advantage of the 5-Series amplier capabilities. Care should be taken in choosing source
components, loudspeakers and cabling. Although all BSC components are designed to be
exible, practical limitations exist for all components and choosing associated components
wisely protects your investment and maximizes the system performance abilities. If there are
any questions or concerns in regards to associated equipment please contact your local dealer/
distributor or BSC directly.
AC Power
BSC 5-Series ampliers are designed to plug directly into any AC outlet and perform as
Designed. Good, clean, and constant power is always a benet to a high performance
audio system. In most cases existing AC power is adequate for installation. When available
a dedicated 15A or 20A line for the amplier is an excellent improvement.
There are several companies that offer products designed to regenerate AC power or Filter
AC power. 5-Series ampliers have excellent noise ltering and ultra quiet power supply
circuitry. They do not require additional noise ltering or AC Line conditioning. In the
event that additional AC Line conditioning/ Filtering is utilized these simple guidelines will
insure proper amplier operation.
AC line conditioning / Regeneration: Many products on the market today are designed to
regenerate and lter incoming AC power, and some products even utilize battery technology
to this end. In the event that the product of choice utilizes an internal power transformer
or supply reservoir to be placed in Series or in-line with the power amplier it is important to
make sure the internal power capacity I.E. transformer/supply/battery size is greater
than TWO times the 5-Series amplier power supply size.
EXAMPLE: An S5 amplier utilizes a 1.4KVA power transformer and is capable of outputting
over 1350 Watts of continuous power. It is recommended that an AC Line conditioner
as described above be capable of at least 2,800 watts of continuous output power.
AC line Filtering: Most of the AC ltering devices on the market today are used in parallel
to the AC power line. Make sure any components utilized are of high quality and adhere to
UL/CE Standards and are not current limiting in any way.
After Market Power Cords: Utilizing an after-market AC power cord is not required for a
5-series product. However, power cords can change the sound in an audio system and
even improve certain qualities you personally listen for. Make sure Power cords utilized are
of high quality and adhere to UL/CE Standards, shielded and are not limiting in any way.
6

Input Connections
Cabling: The 5-Series ampliers are equipped to accept either a Standard XLR type balanced
input cable or a Single-Ended cables via Standard RCA connectors.
Balanced: A balanced cable has three conductors for signal transfer and (typically) a shield:
Pin 1 - Ground
Pin 2 - Non-Inverting (Positive)
Pin 3 - Inverting (Negative)
Balanced cables offer exceptional noise rejection characteristics particularly for long cable runs
but also for short and are the recommended termination for BSC products. 5-Series products
utilize standard locking XLR connectors.
NOTICE: A truly balanced cable has three signal conductors, a cable that only has two
conductors (Hot) and (Ground) is a single ended connection even if XLR
connectors are utilized on one or both sides.
Single-Ended: A Single-ended cable has two conductors for signal transfer and (typically) a
shield:
Center Pin - Non-Inverting (Positive)
Outer Ring - Ground
Single-ended cables were the industry standard for audio connection since the beginning and
are typically the most widely utilized. 5-Series products utilize standard locking RCA connectors.
NOTICE: To minimize noise contamination when using Single-ended inputs, The
5-Series ampliers provide a switch on the back panel labeled XLR /
RCA. When using A single-ended input cable move the switch down to
the RCA position. When using Balanced cables make sure the switch is
in the up of XLR position.

12 Volt Triggers
12 Volt triggers are designed to remote turn On/Off your power amplier and other compo-
nents equipped with 12 volt triggers.
12VDC input: Applying a steady 12 volts DC to the 12VDC Input will effectively bypass the
front panel power switch and turn the amplier ON. When the 12 volts DC is removed the
amplier will shut off. There is one 12VDC Trigger Input, it has a Pink ring and is located at the
top.
NOTICE: 12VDC triggers are terminated with standard 1/8” Mono Jacks.
The tip is 12v Hot (+) and the Sleeve is Ground (-).
12VDC Output: When the power amplier is turned ON there is a steady 12 volts DC output
provided as a convenience to remote turn on another component like another amplier or
Sub-woofer when the power amp is turned on. When the amplier is turned off, the 12VDC
will end and the connected component will shut off. There are two 12VDC Trigger outputs.
Output Connections
Speaker Cables have a special relationship with ampliers in that they are the last electrical
connection in the playback chain before the loudspeaker. They are responsible for the nal
transmission of the delicate audio signal but also provide the power and control conduit that
brings the musical event alive. Cable selection is very important to the overall sonic presenta-
tion of an audio system. It can be considered the last level of system renement after all of the
major components and room set-up has been completed. BSC recommends you take a system
approach to cable purchasing as this will have the best overall tonal balance although it is per-
fectly acceptable to mix and match different manufacturer products.
Speaker Cabling: The 5-Series ampliers are equipped to accept either a Standard Banana
type termination or a 1/4” spaced spade lug.
Spade Lugs: Spade Lugs (or forked lugs) offer excellent surface area and superior clamping
abilities. They are the recommended Speaker cable termination for BSC products. 5-Series
Binding posts are gold plated, and if gold plated lugs are available on your choice of speaker
cable, they will make the best electrical connection despite this other materials can work
extremely well.
Banana Plugs: Banana Plugs are extremely useful when swapping of speaker cables is fre-
quent. When using banana plugs look for the locking (expanding) types as they make the best
electrical connection which is even better if gold plated.
Polarity: BSC ampliers do not Invert polarity, Absolute phase is maintained from Pin 2 (hot)
through all circuitry to the Positive output (+) Make sure Speaker terminations are correctly
connected with the Positive (+) going to the (+) Plus side of the speaker.
Grounding: 5-Series ampliers utilize a single point grounding conguration where all ground
terminations are connected to the same place electrically. The chassis and (-) output are also
directly connected to ground.

Operation
When the AC Power cord is connected to the amplier and plugged into an active AC power
inlet, the amplier is in Standby Mode. No signal can be passed through the amplier, only
the RED Power LED indicator is lit. In this state it can take a command by pressing the POWER
button or it can receive a 12 Volt DC trigger from another component, both of which will turn
ON the amplier.
Power Button: After pressing the power button there will be a soft click and the RED Power LED
indicator will switch to BLUE. After approximately 10 seconds a second click will sound indicat-
ing the amplier is powered ON and ready to play music.
CAUTION: Make sure the Volume control on the preamplier or other source
Component is off or all the way down before you turn ON the amplier.
Because of the extreme power of this product, in some cases, if a full volume
signal were active upon turn-on it could damage the amplier or
severly damage the loudspeaker.
Push the Power button again to turn OFF the amplier.
Brightness Logo Display Control: The Blue illuminated BSC logo is a bold statement that com-
pliments the 5-Series Product design. However, it may not suited to everyones taste. To that
end, there is a Brightness control knob on the back of the amplier chassis provided to dim or
turn on/off the BSC logo as well as the Bias Control indicator LED.
Logo Display Power On/Off - Push the Silver Brightness knob IN until it clicks to Power ON
and again to Power OFF the BSC Logo and the Bias Control LED.
Logo Display Dim - Turning the Silver Brightness knob Counter-Clockwise will dim the BSC
logo and bias level LED, turning the Silver Brightness knob Clockwise will increase
brightness of the BSC logo and bias level LED.

Class A Control: Class A ampliers draw a considerable amount of power from the wall and
additionally generate a lot of heat. Music is frequently played in the background or during
social interactions where focused listening isn’t the main objective. In those cases a lot of extra
power is wasted in unwanted heat generated by classic class A designs. Energy usage being of
major concern to our future at large, and wanting to maximize the ownership experience facil-
itated the addition of a Class A Bias level adjustment switch. The bias switch allows “on the y”
reduction of class A bias on the output stage by 50% and eventually to approximately 98% or
what we call ECO mode. Use of the bias control switch reduces energy and heat used during a
particular listening session without changing the maximum power output capabilities.
Class A levels - There are 3 levels of Class A bias selectable from the front panel control on
the 5-series ampliers.
100% - Represents Full Class A bias for rated power. In this Mode the amplier is
maximized for the very best performance, this is how the amplier was intended to
be measured and heard.
The Knob is in the UP position and the Center LED illuminates Blue.
50% - Represents approximately 1/2 Class A Bias for rated power. In this mode the
amplier effectively becomes a high bias Class A/B amplier. Overall sonic
performance is reduced but power output has not changed. This mode is particularly
good for casual listening, extreme climates, and for a more detailed yet cooler
operating home theater experience.
The Knob is in the RIGHT position and the Center LED illuminates Red.
ECO - Represents approximately 1/8th Class A Bias for rated power. In this mode
the amplier effectively becomes a very cool operating low bias class A/B amplifer.
The listening performance will be reduced yet again as compared to 50% or
100% mode but power output has not changed. This mode is great for
background listening while working or entertaining, extreme climates, ,and for
a more detailed, yet cooler operating, home theater experience.
The Knob is in the LEFT position and the Center LED illuminates Green.

Protection
The 18th century philosopher Voltaire said it best: “With great power comes great responsibil-
ity.” Although the sentiment may be a bit of a stretch for this manual, the point is spot on. BSC
makes extremely fast and powerful ampliers that can drive low impedances with ease. We
have gone to great lengths to make sure the amplier is protected as well as the associated
equipment.
The 5-Series ampliers are protected from the following fault conditions:
Short Circuit / Excessive Current draw: In the event the amplier is shorted while a signal is
passed through it one or more of these protection mechanisms will react.
AC Main Fuse - This can be accessed and replaced on the rear panel. Consult with
BSC, authorized BSC dealer, or distributor for appropriate value information.
Positive or Negative Rail Fuse - These parts can only be replaced by BSC,
Authorized BSC dealer, or distributor
Fuse replacement - The AC main fuse is the only accessible fuse for the end user.
The main AC power fuse is a 3AG 250V 20A FST Blo.
There are several internal fuses that are not to be tampered with unless done so by an
Authorized service technician. Preferably one recognized by BSC.
CAUTION: There are no user servicable parts in BSC 5-Series Ampliers. Any tampering
with the internal contents of the amplifer by non-BSC authorized
Technical personal can void warranty.
After Market fuses - There are several companies that offer special audiophile grade fuses
that claim to improve performance. At this time BSC can not conrm nor deny the results
using these fuses, as long as they mimic the ones used in the unit than there is no reason
for concern.
Excessive DC offset voltage: If there is excessive DC voltage detected at the input of
the amplier or anywhere in the circuit before the speaker terminals the output relays will
open and not allow signal to pass until the fault condition is cleared.
Output protection circuit - The protection circuit is an active device that monitors
the amplier. If the circuit senses DC offset above the specied allowable limit, the
output relay will open and no signal can pass to the loud speaker. Once the
DC source is cleared for approximately a 10 second period the output relay
will engage and music can be played as before. If this persists it is recommended
that you disconnect the Input cable(s) from the amplier and listen to hear whether
the output relays re-engage. If reconnecting the input cable to the amplier causes
the protection to shut off again then the problem is being caused before
the amplier input. Have the preamplier and other source components checked to
make sure they are performing correctly.
12

Protection - Continued
If the output relays do not turn ON after approximately 10 seconds with no cables
connected then there is an internal issue causing the fault. Contact BSC, an
authorized BSC dealer, or distributor to arrange for service.
Excessive Temperature: The 5-series ampliers are designed to run hot, but in the event
the internal temperature is raised above the acceptable set level, the AC power will
disconnect from the power supply circuit. This will prevent any possibility of damage
and initiate cooling the fastest. During this state the front POWER LED will be Blue
even when the main supply is off. At this point press the POWER button to switch the
amplier to stand-by.
Thermal protection: is initialized when the ampliers internal temperature reaches
a point higher in temperature than designed. The biggest cause of a thermal
shut down will be blockage of airow from the bottom of the chassis through
to the top of the chassis. Typical causes for such a failure are:
• Blockage of the top cover vents
• Blockage of the bottom vents
• Space amplier is encased in does not allow enough air circulation and hot air can
not escape at a fast enough rate.
• Bad cable terminations.
• Internal failure
NOTICE: The top cover vents should never be covered or obstructed.
In the event an amplier shuts down thermally, some time must be spent waiting for the
unit to naturally cool off, 10-15 minutes will typically sufce. During the time waiting
for the unit to cool off, check to make sure there are no obvious obstructions
to airow at the top or bottom of the chassis.
EXAMPLE: The amplier has ample height clearance to be placed on most carpeted surfaces.
Sometimes even a heavy shag rug can cause restricted air ow, in this case it
would be best to lift the amplier up with an amplier base or cone feet,
allowing the bottom vents to be free, are popular solutions.
Also check that cable connections are secure, not frayed/ damaged or excessively loose. After
the cooling off period, switch the power amplier back on. If thermal shut down is a consistent
problem please consult BSC, an authorized BSC dealer, or distributor to discuss the fault.
13

After Care
BSC products are designed for a lifetime of effortless performance. All of the internal designs
are supported by the very best components available today, over built and over specied for
the job they are designated to do. Components manufactured outside are of BSC design and
built to the same exacting standards.
All of the external surfaces utilize the highest quality nishes available to maintain color and
luster for years to come. The Outer cosmetic surfaces are painted with an automotive quality
paint process, the Grills, Sub-chassis, and Back panel are nished industrial powder-coat. All of
the remaining nishes are clear anodized. All Assembly fasteners and hardware stainless steel.
BSC products are all Hand Assembled in the USA, manufactured in small batches to ensure the
highest level of quality control.
Cleaning: The 5 series ampliers should require very little cleaning maintenance, with the
exception of dust or ngerprints. It is perfectly safe to use a feather duster or similar to rid the
surface of dust and dirt. Mild non-abrasive solvents and household cleaners are safe for the
nish. Top cover vents should be free of excessive dust or pet hair to maximize air ow.
NOTICE: Cleaning is best done with the unit in stand-by and best if actually unplugged.
