switched on and the electronic circuits are stable. In case of an error in power supply or

should be repaired by an authorised Stage Accompany service center.
Signal present: these LEDs will light when a input level of more than 40 dB under the
level that would cause maximum power is detected. The signal present LEDs work
dependently of the settings of in- and output of the DSP settings. These LED’s indicates

indication is correct for every connected impedance. When the clip LEDs flash fre-
quently, distortion is to be expected.
