6. power amplifier s safety circuit has been triggered to shut off the outputs This can occur if the output connection has been shorted the load impedance is too low there is DC voltage at the outputs or if the power amp overheats due to excessive clipping When either of these LEDs is lit up turn OFF the power and check the output connections to verify that they are correct If the output connections are shorted or a speaker is blown correct the problem or unplug the speaker and try turning the amp back on It s also prudent to carefully feel if the amplifier is very hot due to excessive clipping If so allow the amp to cool down before turning the power back on CONTROLS AND CONNECTIONS BACK PANEL 12 15 13 8 BALANCED INPUT CONNECTORS 1 4 TRS amp XLR These balanced 1 4 6 3mm TRS Tip Ring Sleeve phone jacks and balanced XLR jacks are designed to accept line level balanced or unbalanced signals for each channel They are wired Tip Pin 2 Ring Pin 3 and Sleeve Pin 1 Ground Balanced input signals are recommended as they are less prone to AC hum For long cable runs a source of less than 6000 output impedance is needed to avoid signal loss For short cable runs an unbalanced signal input should be suitable Since the TRS phone jacks and XLR jacks are wired together internally for each channel you can parallel these jacks with another amplifier by connecting either the 1 4 jack or the XLR jack
