O Au LI Ja INPUT 4 waye Description CAP5 has the ability to detect when the amplifier starts to clip or overdrive at its output which can damage loudspeakers and degrade the sound Clipping distortion is caused at high volume levels when the output signal attempts to go outside the maximum voltage that the Clipping amplifier can provide causing the tops of the signal to flatten off When CAP5 detects clipping the volume will be automatically reduced down until CAP5 detects an undistorted output It is possible to disable the clipping detection feature by pressing the CLIP DT button to off when in the 840A V2 System Configure menu Note Disabling the clipping detection is not advised as this feature has been added deliberately to protect the amplifier and loudspeakers Troubleshooting There is no power Ensure the AC power cord is connected securely Ensure the plug is fully inserted into the wall socket and is switched on Check fuse in the mains plug or adaptor There is no sound Make sure the unit is not in Standby mode Check that source component is properly connected Check that TAPE MON is not switched on unless tape input is required Check that your speakers are properly connected If using Speaker B terminals check they are switched on Make sure unit is not in mute mode There is no sound on one channel Ensure that balance control is in the correct position
