6. If an AUX source is connected use the AUX INPUT Level Trim controls on the op of the CL441dsp to adjust the level of the AUX source so that it matches the evel of the OEM source and so that both channels of the AUX source are properly balanced Use similar music or test tones playing through each source unit for best results If the CLIP indicator lights flash or ight continuously reduce the level until they no longer light up 12 That s it You re now ready to enjoy great sound EO DEFEAT MODE If you would like to verify the effect of the ClL441dsp s OEM equalization function you can press the EO DEFEAT button on the top of the unit when it is in OEM Input mode In EQ DEFEAT mode the channel status LED s will flash green and the CL441dsp s response correction is bypassed allowing you to hear the raw response of the OEM audio source The Defeat Mode will stay engaged for up to five minutes or until you press the EQ DEFEAT button again Important Notice for All Users situation do not use the AUX input 10 AMBER steady AUX Input Engaged EQ Defeated This indicates that the AUX input signal is being passed to the CL441dsp s outputs without any equalization RED GREEN alternating EO Active only partial correction was achieved This indicates that the CL441dsp corrected the freguency response to the best of its abilities but failed to achieve a flat respons
