The indicator first comes on as a warning, to either turn down the input level or check the cooling arrangements, after which point the amplifier will mute the input signal. When the cooling fans have returned the output heat sinks back to the normal operating temperature the input signal is un-muted. Th is i n d i c a t o r a l s o i

ENGLISH 5.4.3 Tandem mode In tandem mode two or four of the amplifiers inputs are linked together. To use only one input signal to drive inputs A or B press the (A+B link/bridge) switch and connect a signal to inputs A or B. In this configuration loudspeaker 1 would then be connected across +1 and -1, and loudspeaker 2 across +2 and -2 of the OUTPUT A, B Speakon connector. To use only one input signal to drive inputs C and D press the (C+D link/bridge) switch and connect a signal to inputs C or

ENGLISH Bridged mono mode combines the power of two channels into one loudspeaker. This results in twice the voltage swing, four times the peak power and just less than three times the full power of a single channel. This is because the coil is driven with positive voltage at one pole and an equivalent negative voltage at the other pole. So, if an 8 ohms load is connected in bridged mode, one channel shares one 4 ohms part of the load, and the other channel shares the other 4 ohms part. The pow

ENGLISH 6.5.1 Calculation The current draw can be calculated by dividing the mains input power by the mains voltage. We recommend that you design the power distribution for at least the required current at 1/8 power, or 1/3 power for heavy-duty demands such as concert touring and Industrial music etc. The heat power can be calculated as following: If a headroom figure of at least 5dB (1/3 full power) is used with a 4 ohms load on all four channels of the amplifier.The 1/3 power per channel is th

ENGLISH 10 MAINTENANCE Under normal use the amplifier should provide years of trouble-free service. The only maintenance required by the user is to clean the front grille periodically. In some extreme cases it may be necessary for authorized service personnel to clean the inside of the amplifier. These conditions usually occur after prolonged use, e.g. in environments using "cracked- oil" smoke machines. If you are using your amplifier for heavy-duty use i.e. concert touring or industrial music
