10. both channels 1 amp 2 will be shut down until the fault is cleared Likewise a fault on channel 4 would result in channels 3 amp 4 shutting down etc Limiter operation The amplifier has a separate limiter for each channel and this has been carefully balanced to provide protection against clipping whilst still allowing the full output potential to be realised with music signals Under conditions which would normally cause the output to clip the limiter will automatically reduce the gain to prevent audible distortion Some momentary clipping of music transients will occur but this is generally inaudible and allows the perceived loudness to be greater than if all clipping were strictly eliminated The limiter provides valuable protection for both the loudspeakers and the listener s ears under overdrive conditions Optimising the output of your Microseries System The following combinations drive the largest number of loudspeakers for the greatest area of coverage and use the 4 Ohm capability of the MICROplus for maximum output power 8 MICROdot per channel 2 x MICROdot series 16 Ohm 2 x MICROdot series 16 Ohm 2 x MICROdot series 16 Ohm 2 x MICROdot series 16 Ohm Wired in parallel 8 MICROdot 4 Ohm driven by 80W MICROdot per MICROplus With 4 channels this will give a total of 32 x MICROdot per MICROplus gi G g bel 4 MICR
