Please read this owner's manual in its entirety before operating this unit. After reading this manual, be sure to keep it in a handy place (e. g. , glove compartment). Check the contents of the enclosed warranty card and keep it carefully with this manual. [. . . ] For example, center frequency "250Hz", gain "-8dB" and Q curve "3" can be stored to band 1 on the right channel. LEFT/RIGHT (channel selection) Selects the channel (left or right) to adjust. Set the center frequency (FREQUENCY), gain (GAIN) and Q curve (Q) for each frequency band. X-OVER TIME ALIGN SP GAIN ALL SEAT PRESET RTN 28 DXZ955MC Sound Adjustment English FREQUENCY (center frequency selection) Selects the frequency to be used as the center of the frequency band to be compensated from the range 20Hz to 20kHz. (1/3 octave steps, 31 points) GAIN (gain adjustment) Adjusts the gain (output level) within the range -12dB to +12dB. (1dB steps, 25 points) Q (Q curve selection) Sets one of 1, 3, 5, 7, or 20 as the sharpness of the Q curve. Compensation There is no need to compensate frequency characteristics if they are flat (no peaks or valleys) when you have measured the frequency characteristics with a measuring device. However, sometimes the frequency characteristics rise or fall in some places. Create a frequency curve having characteristics that are opposite to the center frequency of parts where the characteristics rise and fall to cancel out these peaks and values, and make the frequency characteristics as flat as possible. Making the frequency characteristics as flat as possible is called "compensation". On this unit, frequency characteristics can be compensated by P. EQ (Parametric Equalizer). Compensation of frequency characteristics The figure below shows the relationship between the center frequency, gain and Q curve. Q curve (Q) Level F (dB) Q= f Gain (G) 3dB f Frequency curve Center Frequency (F) Frequency (Hz) Flat frequency characteristics can be made by selecting a Q curve opposite to that of the curve to be compensated. Q curve : (Q) Q curve : 20 Q curve : 1 SETTING­X-OVER This function allows you to adjust the speaker setting such as cutoff frequencies or slope matched to the speakers you are using. Each touch of [SP] switches the adjustment items as follows: HIGH MID SUB-W (in the case of 3WAY) REAR (in the case of 2WAY) HIGH. . . Each touch of switches the adjustment items as follows: LPF* LPF SLOPE* HPF HPF SLOPE PHASE LPF. . . * This does not appear when the speaker is selected to "HIGH" in step 4. "LPF" · The adjustment range of "MID" is THROUGH, 630Hz to 10 kHz. (The factory default setting is "2kHz". ) · The adjustment range of "SUB-W" (in the case of 3WAY) or "REAR" (in the case of 2WAY) is THROUGH, 25Hz to 10 kHz. (The factory default setting is "80Hz". ) Q curve The Q curve becomes sharper when the numerical value is increased, and smoother when the numerical value is decreased. DXZ955MC 29 Sound Adjustment English 30 "HPF" · The adjustment range of "HIGH" is 630Hz to 20 kHz. (The factory default setting is "2kHz". ) · The adjustment range of "MID" is THROUGH, 25Hz to 10 kHz. (The factory default setting is "THROUGH". ) · The adjustment range of "SUB-W" (in the case of 3WAY) or "REAR" (in the case of 2WAY) is THROUGH, 16Hz to 250 Hz. (The factory default setting is "THROUGH". ) "LPF SLOPE" and "HPF SLOPE" · The adjustment range is -6dB/OCT, -12dB/OCT, -18dB/OCT. [. . . ] The speaker protection circuit is operating. Wipe the dirt off with a soft cloth moistened with cleaning alcohol. With the SLOPING CONSOLE open, press and hold the [Q] button for 3 seconds or longer. The foreign matter is forcibly ejected. No sound heard. There is a disc other than a compact disc or foreign matter already in place. MP3/WMA files are absent in Write MP3/WMA files onto the disc properly. Use MP3/WMA files encoded properly. CD/MP3/WMA File system is not correct. [. . . ]
