Page 8: Installing Your Amplifier: Electrical Considerations
Page 8 Installing Your Amplifier: Electrical Considerations The amplifier has been manufactured to comply with your local power supply requirements, but before connecting the unit to the supply, ensure that the voltage (printed on the rear panel) is correct. The amplifier is fitted with either Auto sensing power supply operation from 110V to 230V Make sure power outlets conform to the power requirements listed on the back of the unit. -
Page 9: Installing Your Amplifier: Mechanical Considerations
Page 9 Installing Your Amplifier: Mechanical Considerations To ensure that this equipment performs to specification, it should be mounted in a suitable rack or enclosure as described below. Like all high power amplifiers, it should be kept away from other equipment which is sensitive to magnetic fields. Also, this amplifier may suffer a substantial reduction in performance if it is subjected to, or mounted close to equipment which radiates high RF fields. -
Page 10: About Your Amplifier: Dynamic Amplifier Performance Measurements
Page 10 About Your Amplifier: Dynamic Amplifier Performance Measurements The I Series amplifiers are the very latest examples of a ‘dynamic amplifier’. This new ‘breed’ of power amplifiers provide very high peak power levels in a much smaller, and lighter, package than previously possible with conventional designs. -
Page 11: Connecting To Your Amplifier: Line Inputs And Outputs
Page 11 Connecting To Your Amplifier: Line Inputs The inputs are made via 3-pin phoenix / eurostyle connectors, which are electronically balanced and should be connected via a high grade twin core screened cable, as follows. A small, flat blade screwdriver is required to terminate connections in these connectors. Left : Hot (signal +) Middle:... -

Page 13: Operating Your Amplifier: Front Panel Controls And Indicators
Page 13 Connecting To Your Amplifier: Speaker Outputs As the currents involved are very high, and to ensure best performance, the speaker cables should be kept as short as possible and conform to the following minimum requirements: Connecting To Your Amplifier: Speaker Outputs Do not connect the inputs/outputs to any other voltage source such as a battery, mains source or power supply, regardless of whether the amplifier is turned on or off. - Page 14 Hi-Z mode voltage. The LED operation is interlocked with the 100V led. This has nothing to do the mains power operation. 16: Foam filter for air inlet, the advanced cooling system incorporated in the I series amplifier requires air sucked in through front of the amplifier, this air is blown from the exhaust vents on the amplifier rear and side.
