4. Intelligent clipping detection Indication Volume is reduced automatically 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 amplifier can provide causing the tops of the signal to flatten off When CAPS5 detects clipping the volume will be automatically reduced down until CAP5 detects an undistorted output Note The clipping detection is disabled by default The clipping detection can be enabled in the Setup menu see Setup menu section 12 CXA60 80 CXA60 60W RMS into 8 Ohms 90W RMS into 4 Ohms lt 0 002 1kHz at 80 of rated power gt 0 02 20Hz 20kHz at 80 of rated power 5Hz 60kHz 1dB gt 93 dB gt 105 dB Input A1 A4 unbalanced 370mV RMS Input A1 A4 unbalanced 43 kOhm Unbalanced MP3 jack Coax SPDIF TOSLINK Bluetooth via BT100 not supplied Speakers Headphone Preamplifier Output Sub Output gt 110 at 1kHz N A TOSLINK 16 24 bit 32 96kHz Coax SPDIF 16 24 bit 32 192kHz 600W 0 5W Shelving type Max bass boost cut 10 5dB at 10Hz Max treble boost cut 8dB at 20kHz 115 x 430 x 341mm 4 5 x 16 9 x 13 4 8 3kg 18 3Lbs 13 Technical specifications CXA80 80W RMS into 8 Ohms 120W RMS into 4 Ohms 0 00296 1kHz at
