Design Features
The e.One Series S300/M300 are
single and dual-mono amplifiers
designed to deliver up to 150 watts
into 8 ohm loads and 300 watts into
4 ohm loads. Each amplifier contains
its own dedicated regulated power
supply for all amplifier stages, including the output section. This is
achieved in a compact and elegant
product through our adaptation of
the latest analog switching amplifier
and power supply technology from
the ICEpower group.
This technology brings unprecedented performance gains in absolute
musical performance. The regulated
power supply and fully balanced
analog switching amplifier architecture liberates your loudspeakers to
perform at their best. The ultra-low
noise operation insures that the most
subtle of musical expressions comes
through with palpable clarity.
The superb measured performance
insures that harmonic and intermodulation distortion don’t interfere with
the pristine beauty or raw power of
the musical message.
The e.One series amplifiers from
Bel Canto insure that you fully
experience the musical intensity
and beauty of your favorite artists.
Warm Up
The amplifier’s sonic performance will start to stabilize after approximately 100
hours of continuous power up. We recommend that the amplifier remains powered for optimum performance.

Unpacking
Unpacking
The S300/M300 box contains:
1 – User's Guide
1 - Power Cable for connection
to utility power [1.85m,
6' long]
1 – S300 or M300 Amplifier.
1 - Owner's Warranty /
Registration Sheet
Carefully inspect your new unit and
check for shipping damage. If there is
any damage, or if any piece is missing, please contact your dealer, distributor or Bel Canto Design.
Save all packing materials as the
packing is specially designed to protect the amplifier for shipping or
transporting it. If you lose or damage
the packing materials or carton,
please contact your dealer or distributor before attempting to transport
the preamplifier.
The power supply is preset for the
proper AC power line voltage before
you receive it. The power cable will
have the correct plug for your local
power system.
If you believe this is
not true, please contact your dealer
immediately. Do not attempt to alter
or change power settings yourself.
This will void the warranty.
Warning!
Do not connect power to this amplifier yet!
This amplifier, like any electrical component, can be danger
unless correct handling procedures are observed and used. Before
powering this preamplifier it is necessary to read and follow proper procedures
concerning its setup and use.
Any tampering of internal parts will immediately void your warranty.
USA customers: For Warranty Coverage complete and mail the Owner's
Registration Papers immediately.

S300 Rear Panel Connections
S300 Rear Panel
Never Connect Either the Positive or Negative Speaker Output to
Any Ground Contact!
Connecting any Speaker Output on the S300 to Ground will cause the amplifier
to go into protection and could damage the amplifier and void the warranty.
1) Power Switch: Power is on when the
switch is toggled to the I position
and off in the O position.
2) Input Connections and RCA/XLR
switch: When using RCA cables for
the input insure that the RCA/XLR
switch is pressed in to the RCA
position. When using XLR cables
insure that the switch is out in the
XLR position. This will generally
insure ideal grounding and minimize
ground noise from interfering with
the audio signal.
3) Output Connections: Attach your
loudspeakers to the output connectors, insure that the polarity of each
speaker is correct and the same so
that no phase inversion can occur.
Never Connect Either the Positive or
Negative Speaker Output to Any
Ground Contact!
4) IEC power cord jack: Connect a
heavy gauge power cord from
this jack to the wall power supply.
Note the power setting indicated
on the back of the amplifier before
connecting the power.
When all connections to and from the
amplifier have been made then double
check everything, insure that the preamplifier is powered on and set to a
Mute setting and power on the S300.

What to do if there is hum or ground noise:
1) Check that the RCA/XLR switch is in
the correct position for the type of
connection being used.
2) Insure that the preamplifier or any
source components are not producing
hum by setting the preamplifier to a
MUTE or Standby setting.
Front Panel Indicator Lamp
The small blue LED lamp indicates that
the power is connected to the amplifier
and that the power switch is in the
ON position. If the amplifier detects
a fault or short circuit in the output
connections then it will go into a
protection mode and stop playing.
If this occurs toggle the power switch
to the OFF position and check the
speaker cabling to insure that no
speaker output is either shorted
together or connected to a ground.
When you are certain that the loudspeaker cabling is correct then power
the unit ON again and insure that the
Blue lamp is lit and that music will
play.
3) The design of the amplifier reduces
the chance for ground loop induced
hum but we still recommend that
you use shorter interconnect cables
to the preamplifier and connect all
power cables to a common outlet
box or power conditioner unit to
reduce the possibility for ground
current noise being induced into the
audio signal path.
Fuse Protection
There is internal fuse protection in the
amplifier. If the power switch is in the
ON position, the power cable is connected to a functioning power outlet at
the correct voltage and the Blue lamp
is not lit, this indicates that the internal
fuse may have blown. If this occurs
contact your dealer, distributor or Bel
Canto for service. There are no user
replaceable fuses or other parts.
Opening the chassis will void your
warranty.
