Editorial notes added and some of my usual

typos corrected for rev B$

The JU-06A is a sound module that can be used

in conjunction with the K-25m keyboard unit (sold

separately). The sound can be heard through the

built-in speakers. !

The JU-06A can operate on batteries or on USB

bus power. If you are using batteries, insert four

AA batteries, making sure that the batteries are

oriented correctly. %

When turning the unit over, be careful so as to

protect the buttons and knobs from damage.

Also, handle the unit carefully; do not drop it. %

When the batteries run low, the display indicates

“bLo.” Please install fresh batteries. %

Using the JU-06A in conjunction with the DK-01

Boutique Dock (sold separately) %

For installation / removal / angle adjustment, refer

to the DK-01’s Owner’s Manual. %

Using the JU-06A with the K-25m keyboard unit

###eﬀect !

[PWM] slider # # When the [LFO/MAN/ENV] switch is “MAN” (MANUAL) !

###Adjusts the value of the pulse width. !

###!

###When the [LFO/MAN/ENV] switch is “LFO” !

###Adjusts the depth of modulation produced by the LFO. !

###!

###When the [LFO/MAN/ENV] switch is “ENV” !

###Adjusts the depth of modulation produced by the ENV. !

###WHAT IS PULSE WIDTH?!

###Pulse width is the amount of the upper portion of the pulse wave, expressed as #!

###a percentage of the overall wavelength. !

###!

###If the upper and lower widths are not the same, the waveform is called an !

###asymmetric pulse wave.%

[LFO/MAN/ENV] switch #Selects whether the pulse width value is the ﬁxed value !

###speciﬁed by the [PWM] slider (MAN), is modulated by the 3!

###LFO (LFO), or is modulated by the 8ENV (envelope). !

6VCF%

This is a low-pass ﬁlter that passes the low frequencies and cuts the high frequencies. !

CONTROLLER ## EXPLANATION!

###Frequency components above the cutoﬀfrequency are cut, !

###making the sound mellower.%

[RES] slider # # Resonance boosts the sound in the region of the ﬁlter's cutoﬀfrequency.%

###Higher settings produce stronger emphasis, creating a distinctively “synthesizer- !
