Additional information 12 Settings Symptom Remedy The Auto MCACC Setup continually shows an error. • The ambient noise level may be too high. Keep the noise level in the room as low as possible (see also Problems when using the Auto MCACC Setup on page 37). If the noise level cannot be kept low enough, you will have to set up the surround sound manually (page 78). • When using only one surround back speaker, connect it to the SURROUND BACK L (Single) terminals. • To use a 5.1-channel speaker set, use the surround speakers for the surround channel, not the surround back channel. • Make sure there are no obstacles between the speakers and the microphone. • If Reverse Phase is displayed, try the following: - The speaker's wiring (+ and -) may be inverted. Check the speaker connections. - Depending on the type of speakers and their installation conditions, Reverse Phase may be displayed even if the speakers are properly connected. If this happens, select GO NEXT and continue. - If the speaker is not pointed to the microphone (listening position) or when using speakers that affect the phase (dipole speakers, reflective speakers, etc.), it may not be possible to properly identify the polarity. After using the Auto MCACC • There may have been some low frequency noise in the room from an air-conditioner, motor, etc. Setup, the speaker size setting Switch off all other appliances in the room and use Auto MCACC Setup again. is incorrect. • Depending on a number of factors (bass reproduction capabilities of the speakers, room size, speaker placement, etc.) this may occur in some cases. Change the speaker setting manually in Speaker Setting on page 79, and use the ALL (Keep SP System) option for the Auto MCACC menu in Automatic MCACC (Expert) on page 69 if this is a recurring problem.

Professional Calibration EQ graphical output Symptom Remedy The EQ response displayed in the graphical output following calibration does not appear entirely flat. • There are cases where the graph does not appear flat (even when selecting ALL CH ADJ in the Auto MCACC Setup) due to adjustments made to compensate for room characteristics to achieve optimal sound. • Areas of the graph may appear identical (before and after) when there is little or no adjustment needed. • The graph may appear to have shifted vertically when comparing before and after measurements. EQ adjustments made using the Manual MCACC setup on page 71 do not appear to change the graphical output. • Despite level adjustments being made, the filters used for analysis may not display these adjustments in the graphical output. However, these adjustments are taken into account by the filters dedicated to overall system calibration. Lower frequency response curves do not seem to have been calibrated for SMALL speakers. • Low frequencies used in bass management (the subwoofer channel) will not change for speakers that have been specified as SMALL in the configuration, or do not output these frequencies. • Calibration is performed, but due to your speakers' low frequency limitations, no measurable sound is output for display. Display Symptom The display is dark or off. You can't get DIGITAL to display when using SIGNAL SEL. Remedy • Press DIMMER repeatedly to select a different brightness. • Check the digital connections and make sure that the digital inputs are assigned correctly (see The Input Setup menu on page 37). • If the multichannel analog inputs are selected, select a different input function. 89 En
