Using the A/D Input
The MU90R features a special A/D (Analog-to-Digital) Input function that
allows you to connect a microphone, electric guitar or other instrument and
mix in those signals with the MU90R’s Voices. A/D Input is perfect for
singing along with your keyboard performance, since it allows you to blend
the two signals without the need for an external mixer. Or you can use it to
sing or play guitar over backing tracks played from a MIDI sequencer.
There are two A/D Parts — A1 and A2 — and they include several differ-
ent pre-programmed settings that take advantage of the built-in effects of
the MU90R.
The MU90R has two inputs on the front panel. The signals from these
are mixed.
Operation
1
Turn down the A/D INPUT control on the front panel.
2
Connect the microphone, instrument or audio source to the A/D
INPUT jack(s) on the front panel. (Depending on the equipment
you intend to connect, converting adaptors may be necessary.)
