Yamaha REX50 - Manual (Page 7)

& L Output Jacks
These two monaural 1/4" phone jacks deliver the
stereo output signal from the REX50 to subsequent
amplification or mixing equipment. These jacks can
be connected directly to the inputs of guitar amplifi­
ers, keyboard amplifiers, recording equipment or mix­
ing consoles. Since many of the REX50 effects are
true stereo effects, we recommend connecting both
output jacks to the corresponding inputs of a stereo
or two-channel sound system in order to get the best
possible sound. If this is not possible, connect either
of the OUTPUT jacks (L or R) to the amplification
equipment used.
©Stereo Mix Switch
This switch determines whether the signal appear­
ing at the OUTPUT jacks is "effect only" or "effect
plus direct signal." When the switch is ON, the direct
input signal is combined with the effect signal and
delivered to the outputs. When OFF the processed
output of the REX50 only is delivered to the outputs.
The REX50 does allow internal balancing of the in­
put and effect signals as well as output level con­
trol. In normal use, therefore, the STEREO MIX
switch should be turned OFF.
O R&L (MONO) Input Jacks
When using a stereo sound source, such as a stereo
electronic keyboard, plug the instrument's left (L)
and right (R) channel outputs into the correspond­
ing L and R INPUT jacks on the REX50. When using
a monaural source, such as an electric guitar, plug
the instrument's output into the L(MONO) INPUT
jack.
o
Input Level Control
This control should be used in conjunction with the
control panel LED level meter to set the optimum in­
put level for the source used. Adjust the INPUT
LEVEL control so that the - 20 dB and - 10 dB level
meter LEDS light but the CLIP LED almost never
lights while playing the source instrument.
