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. If this happens, the frequency characteristics must be compensated. 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

The Q curve becomes sharper when the numerical value is increased, and smoother when the numerical value is decreased.

Flat frequency characteristics can be made by selecting a Q curve opposite to that of the curve to be compensated.

SETTING–X-OVER

This function allows you to adjust the speaker setting such as cutoff frequencies or slope matched to the speakers you are using. (Crossover)

6.Touchon the right of the display to adjust the setting.

●“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”.)
