The Bryston PowerPac Amplifiers are a modular monaural 

version of our very popular stereo amplifiers but designed to 

be utilized in applications where portability, sound quality 

and flexibility are of prime importance.

The PowerPac Amplifiers are a perfect choice for use as a 

portable power amplifier which can be attached directly to 

the rear of your loudspeaker. This provides for the use of very 

short speaker leads resulting in a much improved loudspeaker/

amplifier interface. The PowerPac Amplifiers can also be bolted 

on the wall for utilization in audio/video surround systems 

(left/right/center/rears/backs) where a non-conspicuous 

power module is required. A further application would be in 

multi-room audio systems where single or multiple amplifiers 

are needed to provide music in adjacent rooms. Finally, with 

the recent popularity in passively or actively amplifying the 

individual drivers in your stereo loudspeakers the Bryston 

PowerPac’s would be ideal for use in this capacity.

POWERPAC 120 SST MONAURAL AMPLIFIER

The Bryston PowerPac 120-SST amplifier, is a superior quality, 

modular, single channel power amplifier delivering 120 watts 

at 8 Ohms, or 200 watts into 4 Ohms. The PowerPac 120-SST 

is essentially a monaural version of our very popular 3B-SST 

stereo amplifier but intended for use in applications where 

portability and flexibility are of prime importance.

POWERPAC 300 SST MONAURAL AMPLIFIER

The Bryston PowerPac 300-SST amplifier, is a superior quality, 

modular, single channel power amplifier delivering 300 watts 

at 8 Ohms, or 400 watts into 4 Ohms. The PowerPac 300-SST 

is essentially a monaural version of our very popular 4B-SST 

stereo amplifier but intended for use in applications where 

portability and flexibility are of prime importance.

MONAURAL AMPLIFIERS

POWER PAC 60 ST MONAURAL AMPLIFIER

The Bryston PowerPac 60-ST amplifier, is a no-compromise, 

modular, single channel power amplifier delivering 60 watts at 8 

Ohms, or 100 watts into 4 Ohms. The PowerPac 60 is a modular 

monaural version of our very popular 2B-LP stereo amplifier 

but designed to be utilized in applications where portability, 

sound quality and flexibility are of prime importance.
