Three CD changer system
Three compact discs can be placed in the disc compartment at the
same time and played continuously. You can select any track on
any of the discs, either directly or in programmed play. You can
change two of the discs while the third is playing.
DSP (Digital Signal Processor) system
DSP circuits can recreate the effect of sounds reflected from walls
or ceilings, to obtain the sound presence of real environments
without the need to connect surround speakers.
There are three DSP modes, with matching equalization curves.
Front surround system
The front speakers provide an effective surround sound environ
ment.
In addition, by selecting a DSP mode, you can obtain the sound
presence of a disco, live music performance or concert hall.
VOCAL FADER and MULTIPLEX functions for Karaoke
Using the following functions, you can enjoy Karaoke with your
favorite music software.
VOCAL FADER function
This function makes the vocal part on ordinary discs or tapes
softer, so you can enjoy Karaoke without special Karaoke
software.
You can also use the AUTO VOCAL FADER function to reduce
the vocal part only while you sing with the connected micro
phone.
MULTIPLEX function
This function mutes the vocal part on multi audio discs or tapes,
so that the accompaniment is heard from both speakers.
You can also use the AUTO MULTIPLEX function to reduce the
vocal part only while you sing with the connected microphone.
Direct play function
If a disc or tape is inserted, you can turn the unit on and begin
playback by pressing one of the direct play buttons. This is a
