Adjustable frequency bands: 20Hz to 20kHz (in 1/3 octave steps) 5 Turn the Rotary encoder to adjust the level. 6 Press SOURCE/POWER to select your desired band width (Q). Adjustable band width: 1, 2, 3. To store the adjusted curve 1) Press and hold any one of the preset buttons (1 through 6) into which you wish to store the adjusted curve for at least 2 seconds. 7 To set another channel, repeat steps 3 to 6. 8 After setting, press EQ to return to normal mode. • The frequencies of adjacent bands cannot be adjusted within 4 steps. • EQ mode is automatically cancelled if no buttons are pressed within 15 seconds. • This function is inoperable when DEFEAT is set to ON (page 17). • When you press DISP/B.OUT, you can switch the Level Indicator display to the EQ Adjustment display.

About the Crossover (CDA-9815RB/CDA-9813R only) Crossover: This unit is equipped with an active crossover. The crossover limits the frequencies delivered to the outputs. Each channel is controlled independently. Thus, each speaker pair can be driven by the frequencies for which they have been optimally designed. The crossover adjusts the HPF (high pass filter) or LPF (low pass filter) of each band, and also the slope (how fast the filter rolls off the highs or lows). Adjustments should be made according to the reproduction characteristics of the speakers. Depending on the speakers, a passive network may not be necessary. If you are unsure about this point, please consult your authorized Alpine dealer. 2 way mode Cut-off frequency (1/3 octave steps) Slope Level HPF LPF HPF LPF Low range speaker ---20 Hz 200 Hz ---FLAT, .6, .12, .18, .24 dB/ oct 0 to .12 dB Rear high range speaker 20 Hz 200 Hz ---FLAT, .6, .12, .18, .24 dB/ oct ---0 to .12 dB Front high range speaker 20 Hz 200 Hz ---FLAT, ...
