E Series – E15 & E25 Operating Instructions 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.
E Series – E15 & E25 Operating Instructions 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.
Page 10 About Your Amplifier: Dynamic Amplifier Performance Measurements The E15 and E25 are modern 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 amplifiers.
E Series – E15 & E25 Operating Instructions Page 11 Connecting To Your Amplifier: Inputs The inputs are made via 3-pin XLR connectors, which are electronically balanced and should be connected via a high grade twin core screened cable, as follows:...
E Series – E15 & E25 Operating Instructions Page 12 Connecting To Your Amplifier: Speaker Outputs The speaker outputs are via Neutrik Speakon connectors. 2 pole (NL2FC) connectors can be used, but 4 pole (NL4FC) connectors should be used to connect to the bridge/stereo 4 pole output socket.
E Series – E15 & E25 Operating Instructions Page 13 Connecting To Your Amplifier: Bridged (Mono) Operation Use the centre Speakon connector marked Bridge/Stereo, and depress the button between the XLR connectors to the “Channel Link [A]” position. Connect the speaker as follows:...
E Series – E15 & E25 Operating Instructions Page 14 Operating Your Amplifier: Front Panel Controls and Indicators 1: Power Switch: This single pole switch turns the amplifier fully off (but does NOT isolate it from the mains supply). 2: Power LED: This indicates when the amplifier is active. This does NOT indicate the presence of a mains supply when the power switch is OFF.
E Series – E15 & E25 Operating Instructions Page 15 Typical conditions that could cause the protection to be triggered include very high frequency or subsonic input signals, DC in the inputs, short-circuited outputs, or internal high temperatures. The protection circuit can affect both channels or an individual channel, depending on the type of fault.
