Vocal Harmony; (Psr-740); Setting Up - Yamaha Portatone PSR-640 Owner's Manual

Vocal Harmony

This extraordinarily powerful feature uses advanced voice-processing technology to automatically pro-
duce vocal harmony based on a single lead vocal. Four distinct harmony modes as well as an extensive
selection of preset harmony types are provided. In addition to straightforward harmony, the PSR-740
also lets you change the apparent gender of the harmony and/or lead vocal sound. For example, if you
are a male singer, you can have the PSR-740 automatically generate a two-part female backup. A
comprehensive set of parameters gives you exceptionally precise and flexible control over the vocal
harmony sound.

Setting up

1
Set the INPUT VOLUME control to "MIN."
2
Connect a microphone to the MIC/LINE
IN jack of the PSR-740.
3
Set the MIC/LINE panel switch to "MIC."
4
Adjust the INPUT VOLUME control while singing into the
microphone.
Use the SIGNAL and OVER indicators to determine the
appropriate setting.
With the INPUT VOLUME control at the minimum, sing
or talk into the microphone at the highest expected vol-
ume. Gradually bring the control up toward "MAX" so
that the SIGNAL indicator is lit and the OVER indicator flashes occasionally.
Then reduce the INPUT VOLUME just enough to keep the OVER indicator
from flashing. This should be the optimum level setting
Using the "LINE" setting
Normally, since you will be using a microphone, you may never need to use the "LINE"
setting. However, this may come in handy if you want to use a pre-recorded source (on CD
or cassette tape) with the vocal harmony feature. (For best results, the source should be a
single vocal only; any other singers and instruments in the mix could produce unexpected or
undesired results.)
To do this:
1 Set the INPUT VOLUME control to "MIN."
2 Connect the source to the MIC/LINE IN jack.
Use a stereo-to-mono cable or a "Y" cable to
combine the left- and right-channel output
signals from the source device for input to
the PSR-740's mono MIC/LINE IN jack.
3 Set the MIC/LINE panel switch to "LINE."
4 Adjust the INPUT VOLUME control.
Play the source at the highest expected volume, and adjust the INPUT VOLUME control
to get the optimum input level (as in the "Setting Up" instructions above).

(PSR-740)

• A standard dynamic
microphone with an
impedance of about 250
ohms is recommended. (The
PSR-740 does not support
phantom-powered
condenser microphones.)
• If the OVER indicator lights
regardless of the INPUT
VOLUME setting, the output
level of the microphone (or
other source) is probably too
high. Compensate by
reducing the output level of
the source.
CAUTION
• Never use the "MIC"
setting with a line level
signal (CD player, cassette
deck, etc.). Doing this
could damage the PSR-740
CD player, etc.
and its input functions.
