With the upgrade of the PD204 to version 1.01,

the following changes have been made.

(1) The limiter parameter setting function in the

SYS SETUP menu of the MENU mode has been

enhanced.

(2) The key operation for the disk copy function

has been changed.

Before you make parameter setting for the in-

Limiter parameter setting

• Limiter parameter setting for input channels 1 through 4 (Limiter CH-Input)

Highlight "Limiter CH-Input" in the SYS SETUP menu and press the [ENTER/YES] key.

The display now shows the screen for setting limiter parameters of the input chan-

nels, including grouping, threshold, ratio and level detection mode.

The limiter parameter setting function has been enhanced and you can now make limiter pa-

rameter setting for the input channels and stereo output busses individually.

With the earlier version, the "Limiter parameter" menu item in the "SYS SETUP" menu of the

MENU mode is provided to make limiter parameter setting for both the input channels and

stereo output busses simultaneously. With version 1.01, the "Limiter CH-Input" and "Limiter ST-

Out" menu items are provided instead of the "Limiter parameter" item.

<Before upgrade> <After upgrade>

• Limiter parameter setting for stereo output busses (Limiter ST-Out)

Highlight "Limiter ST-Out" in the SYS SETUP menu and press the [ENTER/YES] key.

The display now shows the screen for setting limiter parameters of the stereo output

busses, including threshold, ratio and level detection mode.

Grouping setting (available only for "Limiter CH-Input")

You can select "Mono" or "1-4". (The default is "Mono".)

Mono

1-4

Each input channel limiter works independently according to each input signal level.

The limiters for channels 1 through 4 are grouped. All the channel limiters work together ac-

cording to the highest input level among channels 1 through 4.Therefore, when the limiters

work, all signals are compressed at the same ratio and the stereo position of each signal is

maintained.

<Note>:

The limiters for stereo output busses L and R are always linked (grouped) so

there is no "Grouping" setting item.

Key operation for the disk copy function

With the new version, the key operation for executing disk copy is changed. For details about the

disk copy function, see page 107 of the operation manual.

Key operation with the earlier version (see page 109 of the operation manual.)

After the display shows the confirmation message as below, press the [ENTER/YES] key.

Key operation with the new version

After the display shows the confirmation message as below, press the [ENTER/YES] key while

pulling the [REC] key to the right.

Threshold level setting

Ratio setting

You can select "-6dBFS" or "-12dBFS". (The default is "-6dBFS".)

Limiter level detection mode setting

You can select "1:3" or "1:5". (The default is "1:5".)

You can select "Peak" or "RMS" (The default is "Peak".)

Peak

RMS

<Note>:

The RMS mode is available when the FS is 48 kHz or less. When the FS is higher

than 48 kHz, the limiter works in the peak mode.

The level detector detects the peak level of a signal.

The limiter is activated when the peak level of the signal exceeds the threshold level.

If you select "Peak" while you set the threshold level to "-12dBFS", you may feel the limiter

works too sensitively compared to a conventional analog limiter.Therefore when you select

"Peak", it is recommended that you set the threshold level to "-6dBFS".

The level detector detects the RMS level of a signal.

The limiter is activated when the RMS level of the signal exceeds the threshold level.In this

mode, the limiter works similar to a conventional analog limiter.
