OPERATIONS OF FUNCTIONS
1. Karaoke program
Functions for processing the Karaoke audio signals are described here.
Function
Description
Control register
Coefficient register
Controllable
mode
De-emphasis
De-emphasizes audio input signal that has been emphasized.
Specifies a sampling frequency and on/off of de-emphasis.
OPR[1]
OPR[7:6]
N,E
Input Fader
Controls fade-in/out for audio input signal.
Specifies fade-in/out for each channel after setting fade time (See Note.)
VCR[1:0]
TMR[7:0]
N,E
Voice Cancel
Reduces mid-range signal of inputted audio signal that is located in the center of the sound field such vocal signal
generated by stereophonic CD.
Specifies voice cancel on/off after setting sampling frequency and fade time. (See Note.)
VCR[4]
TMR[7:0]
OPR[7:6]
N,E
Key Control
Changes key of inputted audio signal, and controls key shift for audio input signal. The amount of key shift must
be specified.
KSR[4:0]
N,E
Tone Control
Controls tone of inputted audio signal in three frequency bands.
Specifies the levels for bass (fc = 200 Hz), treble (fc = 5 kHz), and mid-tone (fc = 1 kHz) after selecting a
sampling frequency.
TCR[7:0]
RVR[3:0]
OPR[7:6]
E
Surround
Applies Y mersion surround to audio input signal. One of four types of surround modes is selected and Output
levels for R and L channels are set individually based on the selected surround mode.
KSR[6:5]
C01,C04
N,E
Microphone
level detection
Detects and reads the level of signal input from microphone.
Specifies the time constant for level detection.
MLR[7:0]
C14
E
Microphone
Echo
Applies echo to signal from microphone processed by setting delay and feedback.
Specifies delay time, feedback level and output signal level for L/R.
C05,C08,C0B,C0C
C16,C17,C00,C03
N,E
Stereo Echo
Expands echo by providing stereophonic output.
C1A,C1B
E
Reverberation Echo Damps echo naturally by adding reverb function.
RVR[4]
E
Microphone
key control
Applies microphone echo by subjecting signal inputted from microphone to key shift.
Specifies the amount of key shift and output signal level for L/R.
KER[7:0]
C18,C19
E
Microphone
Y mersion
Applies YMERSION to microphone echo to obtain expansion that is specific to YMERSION.
Specifies output signal level for L/R.
C1C,C1D
E
Soft Mute
Noiseless mute, Specifies on/off.
OPR[3]
N,E
Volume
Controls volume.
Some of the functions can be set in either of KP2 standard mode or KP2V extended mode, some only in KP2V
extended mode.
C02,C06,C09,C0A
C0D,C0E,C0F,C15
C1E,C1F
N,E
Note ; The fade time is applicable to the input fader and voice cancel functions.
