Customizing Digital Echo settings (See Figure 1)
When using Digital Echo, you can customize the effect by adjusting the ECHO, REPEAT and DELAY controls.
First set the ECHO level control to 5. Then customize the effect with the REPEAT and DELAY level controls.
REPEAT adjusts the interval repetition of the echo effect. As more REPEAT is applied, more echo intervals
will be heard when using it and vice versa. DELAY adjusts length of each interval. As more DELAY is applied,
there will be more “space” between the starting and ending point of each echo. When the Digital Echo effect
is customized, adjust the ECHO level control as you would a master level control.

Vocal Partner/Vocal Eliminator/Multiplex features v(See Figure 2)
The VOCAL button can switch between three modes
1. MULTIPLEX - With Multiplex media, music and lead vocals are panned hard left and right. With the first
press of this button, the red MULTIPLEX LED is lit, indicating that lead vocals have been removed. This feature
is also known as VOCAL CANCEL. The channel with music only is duplicated so it is heard in both left and right
channels. Some backing vocals will remain if there is overlap in the way they are recorded.
2. VOCAL PARTNER - Pressed two more times, the VOCAL button will illuminate the yellow LED to indicate
VOCAL PARTNER and “guide” or “lead” vocals will be activated. In this mode, the vocal layer will be cancelled
only as long there is Mic activity present. When there is no Mic/Line activity present, the vocal layer appears
for continuity. In other words, while you are singing, the vocal layer is cancelled, and when you are not singing,
the vocal layer is output. This mode is commonly used when a solo singer wants to simulate a duet, with the
KJ-7800 as the “partner.”
3. VOCAL ELIMINATOR - Press the VOCAL button until the center, green LED illuminates. With standard
recordings, you will be able to partially remove lead vocals to turn any recording into a Karaoke performance
or for remixing possibilities. It is not possible for such an effect to entirely remove vocals from a recording
because it operates by selecting certain frequencies that best represent the vocal range in the center of a
mix. Naturally, this removes other tones in these frequencies with it. To return to regular disc playback, press
this button until all three LEDs are unlit.
