GENERAL INSTRUCTION S Setup Recommendations: Description: General Information: Thank you for choosing a Bryston product. We would welcome any comments or suggestions you may have regarding the operation of y our amplifier. We consider our customer to be Bryston,s most important r e- source and your opinion is very much appr e- c iated. In the unlikely event you have a pro b- lem with your amplifier and must return it for service please keep the original box and all packaging material. The Bryston Po werPac 60/120/300 are high quality modular single channel 60/120 /300 watt power amplifier intended for use in applications wher e portability, quality and flexibility are of prime importance. The PowerPac is a perfect choice for use as a modular power a mplifier which can be attached directly to the rear of your lou d- speaker . It can also be bolted on the wall, or in the wall, for utilization in audio/video su r- round systems (left/right/center/rears) where a non -conspicuous power module is required. Another application would be in multi -room audio systems where single or multiple ampl i- fiers are needed to provide music to other rooms. We recommend that you do not place the amplifier in a totally enclosed area. Allow some space at the top, sides as your Bryston amplifier relies on convection cooling and some air flow is desirable. Make sure the power switch on the front panel of the amplifier is in the off (out) position. Plug the power cord into the front panel of the amplifier, then insert the male end int o the wall outlet. All Bryston amplifiers contain high quality, dedicated circuitry in the power su p- plies to reject RF, line spikes and other power -line problems. Bryston power amplifiers do not r e- quire specialized power line conditioners. Plug the amplifier directly into its own wall socket. Connect your loudspeakers ens uring that the positive (red) and ground (black) te r- minals on your amplifier are connected to the positive and ground terminals on your lou d- speakers. Note: Make sure that the front panel switch for choosing balanced or non - balanced is in the correct position. The Bryston PowerPac 60 monaural amplifier consist of two of Brystons custom power transistors as output devices. The power o utput is 60 Watts @ 8 Ohms. The Bryston PowerPac 120 monaural amplifier consist of four of Brystons custom power transistors as output devices. The power output is 120 Watts @ 8 Ohms. The Bryston PowerPac 300 monaural amplifier consist of eight of B rystons custom power transistors as output devices. The power output is 300 Watts @ 8 Ohms.

BRYSTON POWERPAC 60/12 0/300 Grounding and Ground LIft Switch (except PP300 and PP120): Input and Output Connectors: Bryston PowerPac amplifiers come standard with two input connectors: one u n- balanced RCA/phono connector and a ba l- anced combination XLR - 1/4 -inch jack with fully discrete active input circuitry. All input connectors are gold -plated and sh ould only be used only with high - quality, gold -plated interconnect cable as a poorly plated connector will eventually co r- rode through the gold flash. Bryston offers interconnect cables with heavily gold plated, quality connectors available throu gh any Bryston authorized dealer or directly from Bryston. Output connectors consist of one pair of five -way binding post terminals (1 red and 1 black) that can accept either sta ndard banana plugs, spade lugs, pins or bare wire. Since the binding posts are gold - plated, we recommend gold plated conne c- tors also be used on the speaker cables. All Bryston amplifiers will accept ba l- anced or single -ended (RCA) input conne c- tors. The balanced inputs use combination 3 -pin XLR (pin -1 -ground), (pin -2 -+) and 1/4 -inch tip -(+), ring and sleeve (ground) i n put connectors. A ground lift switch is located on the front panel of the amplifier. It is connected b etween the chassis ground (including the third prong on the power cord) and the signal ground. This switch is normally left in the co n- nected (up) position. Occasionally a multi - amplifier installation or an unusual grounding situation with another component (CD p layer, video recorder, television etc.) will cause a ground loop between the signal ground and the chassis ground. This switc h will reduce the resultant hum in many cases without r e- sorting to a cheater plug by switching to the separated (down) position. Note: this switch does not disconnect the cha ssis from the third prong on the power cord which must be left intact for safety reasons. Power Clipping Indicator Dual colour LED pilot lights indicating GREEN at normal level, flashing \ RED at clipping.
