Thank you for choosing a Bryston product. We 
welcome any suggestions you may have, or 
comments regarding the operation of your am-
plifier. We consider you, our customer, to be 
Brystons’ most important  resource, and your 
opinion is very much appreciated.  
 
Bryston products are warranted to be free from 
manufacturing defects for a minimum of 20, 
(twenty), years from the original date of  manu-
facture. This includes all parts, labor and one-
way return shipping.  This warranty covers the 
original owner and any subsequent owners. The 
warranty is retroactive for any Bryston product 
purchased within the last twenty years.    

Tampering by anyone other than factory author-
ized personnel voids the warranty. Warranty 
service may be obtained by returning the unit to 
any authorized Bryston dealer or distributor. 
You may also contact the Bryston factory or na-
tional service offices directly at the location 
listed on the rear page of this manual.  
 
Please keep the original box and all packing 
material. This will ensure the amplifier is pro-
tected in the unlikely event you have a problem 
and must return it for service. No warranty card 
is necessary to initiate your coverage. Please 
refer to the back page for more detailed war-
ranty information. 

CAUTION:  Your 14B ST is a Stereo Amplifier 
only and the outputs should never be con-
nected in Series/Bridged or Parallel modes.  
 
Make Sure The Circuit Breaker Switch Is OFF 
Until All Connections Are Made

 
Power Switch(s): 

There are two power switches 

on the 14B. The front panel 

‘ST’ 

Power Switch 

and the rear panel On/Off Circuit Breaker. 
  
The 14B has two, 2-position slide-switches labeled 

Power Up 

and 

Ext Trig 

and

 1-Circuit Breaker  

Factory Settings are: 

 

POWER UP – LOCAL,    
EXTERNAL TRIGGER – LOCAL,  
CIRCUIT BREAKER SWITCH – OFF 

 

 

After confirming that all switches are in the proper  
positions and all input and output connections are  
correctly made, plug the amplifier into the proper 
wall outlet and activate  the circuit breaker switch. 
The power amplified may now be turn on or off us-
ing the front panel 

‘ST’ 

power switch. 

If the rear panel 

power-up 

switch

 

is in the 

‘Local’ 

position and the amplifier is connected to the A/C 
power source the amplifier will turn on/off using the 
front panel 

‘ST’ 

power switch. If for any reason the 

power is removed from the A/C line (ex: power fail-
ure) the amplifier will turn off and 

will not 

turn on 

again after A/C is restored until the front panel 

‘ST’

 power switch is manually reactivated. 

When the rear panel 

power-up 

switch is in the 

‘Auto’ 

position then any time A/C power is sup-

plied 

(Power Bar, Switched power outlet etc.) 

the 14B 

will automatically power-up without having to acti-
vate the 

‘ST’ 

power switch. 

 

The Bryston 14B-ST is a Stereo 2-channel  
power amplifier consisting of two totally inde-
pendent amplifier modules, each with its own 
power transformer and +/-60V power supply. 

Each audio channel provides connections for 
balanced or single ended input and will sup-
ply a minimum of 500 watts of power into 8 
ohms or 800 watts into 4 ohms.
