Installation and starting up Installation and starting up Unpack and check carefully there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the product against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively.
Connections and controls Connections and controls Front panel ö ö 1 [CH-A] / [CH-B] | Input gain controls for channels A and B 2 LED indicators [CH-A] /[CH-B] | These LEDs indicate the ready status of the device ([Power]), the input signal level ([Signal]), channel overdrive ([Clip]) and a fault condition ([Fault]).
Page 13
Connections and controls The [Power] LED is permanently lit during operation. The [Signal] LEDs respond to the input signal. If any of these LEDs light up without an input signal present, disconnect the speakers from the power amplifier and turn the input gain controls of channels A and B down to minimum.
