Automatic Noise Reduction
Like in all other amplifiers there is a slightly hearable murmur in HAISER Sound System if the
volume is set very high. To prevent the user from hearing it during breaks in speech or music, the
amplifier is automatically reduced within a few seconds if the source signal gets under 3 mV. As
soon there is another source signal, the amplifier will be increased again within 300 ms. For cer-
tain uses it might however be necessary to temporarily disable the Automatic Noise Reduction:
Disable Automatic Noise Reduction:
• Hold VOL– in Standby Mode until the red Standby LED slowly flashes one time.
Enable Automatic Noise Reduction:
• Hold VOL– in Standby Mode until the red Standby LED rapidly flashes three times.
