• 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 "OZE OFF".
2-1. Select "BASS".
2-2. Press the
[~II
ENT] button.
2-3. Push the [SEEK PANEL] leftward or
rightward and select from:
"B GAIN"
+-+
"B FREQ"
+-+
"B Q"
3-1. Press the [UP] or [ON] button to adjust the
gain, the FREQ (center frequency) and the
Q.
B GAIN: -7
to
7
(The factory default setting
is "0")
B
FREQ:
50Hz/80Hz/120Hz (The factory
default setting is "50")
B Q: 1/1.25/1.5/2 (The factory default
setting is "1")
3-2. Press the
[~II
ENT] button to return to the
previous mode.
• 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.

3-2. When the "OZE 1", "OZE 2" or "OZE 3" is
set, press the
[~II
ENT] button. Then
press the [UP] or [ON] button to change the
DZE level from +3 to -3.

The factory default setting is "0".
3-3. Press the
[~II
ENT] 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".
• Compensation of frequency
characteristics
The figure below shows the relationship
between the center frequency, gain and Q
curve.
• 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 "OZE".
3-1. Press the [UP] or [ON] button to select the
tone effect. Each time you press the [UP] or
[ON] button, the tone effect changes in the
following order:
"OZE OFF"
+-+
"OZE 1"
+-+
"OZE 2"
+-+
"OZE
