●Setting the Digital Z-Enhancer

This unit are provided with 3 types of sound tone effects stored in memory. Select the one you prefer.

∗The factory default setting is “DZE OFF”.

2-1. Select the “DZE”.

3-1. Press the [] button.

3-2. Push the [SEEK PANEL] leftward or rightward to select the tone effect. Each time you push the [SEEK PANEL], the tone effect changes in the following order:

“DZE OFF” ↔ “DZE 1” ↔ “DZE 2” ↔ “DZE 3”

DZE OFF

DZE 1

DZE 2

DZE 3

3-3. When the “DZE 1”, “DZE 2” or “DZE 3” is set, push the [P.CH] button upward or downward to change the DZE level from +3 to –3.

∗The factory default setting is “0”.

3-4. Press the [] button to return to the previous mode.

●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”.

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.

Q curve : 20 Q curve : 1

●Adjusting the bass

The bass gain, bass FREQ (center frequency) and bass Q can be adjusted as follows.

The adjustment can only be performed when the DZE is set to “DZE OFF”.

2-1. Select “BASS”.

2-2. Press the [				] button.

2-3. Push the [SEEK PANEL] leftward or rightward and select from:

“BASS GAIN” ↔ “BASS FREQ” ↔ “BASS Q”
