(Cubed) amplifier! Decades of ongoing research
and development have produced our highest
performing amplifiers yet. Our customers are
a tremendous resource to whom we look for a
measure of success. Please feel welcome to contact
us with feedback and suggestions.
Description
The 14B
3
is a dual-mono design audio power
amplifier with two channels capable of 600 watts
each intended for use in very high performance
professional audio systems. Robust yet beautiful
machined aluminum enclosures house our
proprietary industry-leading circuit designs
resulting in exemplary performance observed both
in the listening space and in the laboratory.
C-Series variants are available in your choice of 17
inch or 19 inch wide non-rack mountable aluminum
dress panels anodized in clear (silver toned) or
black. All models feature rear handles. Nineteen
inch wide C-Series amplifiers include front mounted
handles. PRO amplifiers feature 19 inch wide rack
mountable dress panels with handles in a black
anodized front finish and also include individual
channel trims located on the rear panel.
Features
Bryston 14B

includes the following features:
• Switchable gain: 23dB or 29dB
• Balanced (XLR or TRS) input. Pin 2 positive.
• Single ended (RCA) input.
• SoftStart circuitry for managing inrush current
upon initial power up.
• Wired remote control AC/DC trigger input and
passthrough with supplied connector.
Shipping Box and Packing Material
Please keep the original shipping box and all
packing material. This will ensure the amplifier is
protected in future transport. In the unlikely event
you have a problem and must return it for service,
you must use the proper packing material. Ship
the amplifier only in the original packing material,
as the unit is not insurable by carriers otherwise.
Replacement packing materials consisting of a
shipping carton with plastic foam inserts is available
from Bryston for a small fee.
Installation and Usage
Ventilation
Bryston has deliberately chosen to omit fans from
our amplifiers in an effort to minimize the noise
level in your listening environment. Instead, we use
only passive heat sinks which are fully capable of
maintaining a safe operating temperature of the
amplifier even under loud playback conditions.
For them to work most effectively, air must be
permitted to pass freely through the heat sink fins
and around the amplifier. Maintain a minimum of
3.5 inches of space to each side, top and back of the
amplifier when in use. Do not stack the amplifiers
immediately on top of one another in an enclosed
cabinet. If you must stack the amps, you may need
to utilize fans or another active cooling mechanism
to ensure uninterrupted operation. If you repeatedly
experience channels shutting down due to heat,
rearrange the amplifiers to have more surrounding
free space, or employ an active cooling solution.
Never operate the amplifier in a vertical position.
Connecting to A/C Power
Please check the Data Plate on the right rear of the
amplifier to verify power requirements agree with
your location. See “11. Data Plate:” on page 9.
Before plugging in the power cord, make sure the
Master Circuit Breaker (“7. Master Circuit Breaker:”
on page 9) is switched to the ‘ON’ position. Plug
the IEC-320 C14 end of the power cord into the
amplifier, then plug the other end into an approved
and grounded A/C receptacle. The STATUS LED
should flash green, then switch to red indicating A/C
power is present in the unit. See “10. Power Status
Indicator:” on page 9. The amplifier is now ready
to be powered on.
