Write User
This function allows you to save the settings you 
made on the “Compressor” page.

Rotate the [CURSOR÷VALUE] dial to select 
“YES”, then press the [ENTER/SELECT] but-
ton to save the current settings.

The display shows a confirmation message.

If you don’t want to define the current settings as 
the default state, rotate the [CURSOR

÷VALUE] dial to 

select “NO”, then press the [ENTER/SELECT] button. 
The BK-5 then returns to the “Compressor” page.

There is only one “User” memory for your own settings. By 
saving new settings, you therefore overwrite the previous 
ones.

When you switch on the BK-5, it automatically loads the 
“User” settings.

To edit the Equalizer parameters, use [MENU] button ‰ 
“Mastering Tools” ‰ “Equalizer”.

The equalizer has the same function as the TREBLE, MID 
and BASS knobs on a mixer: it allows you to color the 
sound, or to apply tonal corrections.

The equalizer is now active and will affect the key-
board parts and SMF song or rhythm playback. 
(Select “Off” to switch the equalizer back off.)

Use the [CURSOR÷VALUE] dial to select the 
“Preset” parameter, then press the [ENTER/
SELECT] button.

Rotate the [CURSOR÷VALUE] dial to select 
one of the available presets.

The available presets are:

Threshold

–36~0dB

This parameter allows you to 
set the level the frequency 
band (“High”, “Mid” or 
“Low”) must reach to trigger 
its compressor. The lower 
the value, the more notice-
able the compression will be.

Ratio

1:1.0~
1:INF

Use this parameter to spec-
ify how strongly the level 
should be reduced when the 
band’s level exceeds the 
“Threshold” level. “1:2.0”, for 
example, means that level 
values above the “Threshold” 
level are halved. “1:INF” is 
useful if you set “Threshold” 
to “0dB” or thereabout. This 
produces a limiter effect, 
which means that no signal 
level will ever exceed the 
“Threshold” value. This may 
help you protect the speak-
ers of the PA system etc.

Level

–24~
+24dB

This parameter allows you to 
establish the desired mix 
among the three compressor 
bands. Choose a negative 
value to decrease the level, 
or a positive one to increase 
it. Choose “0” for a band 
whose level is OK as is.

Split High

2000~
12000Hz

These two parameters spec-
ify the frequency where two 
bands are separated. The 
compressor has three bands, 
and so there are two cross-
over frequencies you can 
set: “High” between the 
“Mid” and “High” ranges; 
and “Low” between the 
“Mid” and “Low” ranges.

Split Low

80~800Hz

1. Flat
2. Rock
3. Pop

4. Jazz
5. Classic

6. Standard
7. User
