 PRECAUTIONS
You may seriously damage any transistorized audio
unit by being careless when you first operate it. Care-
lessness is the major cause of audio repairs. Avoid
disappointment by following the precautions listed
here BEFORE plugging in or attempting to operate
your EM-100 or EM-80.
e Before you plug in the power cord please check
that the voltage selector is set to your local current.
If not properly set, turn the knob and reset it to
the correct voltage position.
Voltage settings: 110, 130, 220, 240V (the 150,
260V settings are not connected). U.S., Canadian,
European and Australian models are set to the
proper voltage before shipment.
Make sure the power switch is off before plugging
in the power cord.
Unplug the power cord as a safety measure, or at
the very least be sure the power switch is off,
before connecting or disconnecting any cords.
Protect the unit from heat, humidity, dust and
shocks. Keep the unit away from direct sunlight
or other sources of heat.
Be sure there is sufficient space around, behind and
under the unit for proper ventilation.
Do not switch input selectors while the amp is
in use.

O Rec. Out Jacks
These jacks are for feeding the signal to a tape
deck or recorder for recording. These jacks have
the unusual feature of serving as signal input ter-
minals as well, when the signal is from another
EM unit. See page 5 for details.
@ Echo Jacks
Feed the signal out to an echo unit via the To
Echo jack, then back in through the From Echo

Extra Channels with a Second
Unit
A second unit can be connected
for extra channeis in two ways:
(A) Connect from the sub unit
Rec. Out jacks to the main unit
Aux. jacks. In this case the
volume can be controlled by
the main unit Aux. Volume
knob.
(B) Connect from the sub unit
Rec. Out jacks to the main unit
Rec. Out jacks. In this case
the volume is controlled by the
main unit Master Volume knob.
H you wish a separate volume
control independent of the Mas-
ter Volume, use (A) connection;
if you do not, use (B).
FRONT PANEL PARTS & CONTROLS
EM-80
O Input Selectors
Each selector has three settings. Use LINE for a
signal from an audio unit such as a tape deck, record
player, etc. Use INST. for electric guitar, bass,
combo organ and any other electric instrument.
MIC is for a microphone connection, regardless of
whether the microphone is used for voice or for a
wind instrument, acoustic guitar, etc.
Balance Controls
Each control can be used to divide that channel
input between left and right channels, for all the
outputs. Turning all the way to the left feeds
that signal to the left channel only. The center
position provides even balance between both cha-
nnels.
© Reverb/Echo Controls
If you wish to use either Reverb or Echo, you can
blend the effect into each channel individually with
the continuous control. The reverb effect is built
in, but echo requires a special echo unit.
Connecting the echo unit to the Echo jacks will
change the Reverb to Echo.
Tone Controls
Each channel has its own Treble and Bass tone
controls, which affect each end of the frequency
scale. Turning either knob clockwise accentuates
the tones (high or low) controlled by that knob.
Volume Controls
Each channel has its own Volume knob. Turning
the knob clockwise increases the volume.

volume is independent of the other volume controls,
including Master Volume.
® Monitor Volume Control
Controls the combined volume of the signals from
ali the channels going to the Monitor Out output.
@ Master Volume Control
Used to control the combined volume of the signal
from all the channels going to the Speaker and
Phones outputs.
Phones Jack
This stereo jack can be used for stage or other
monitoring.
VU Meters (EM-100 only)
These meters show the volume level of the unit's
overall output signal from the Speaker jacks (i.e.,
the signal controlled by the Master Volume knob);
they do not show the signal level from the Rec. Out
jacks. If the level is so high that the needle on
either or both channels exceeds +3, sound distortion
will result.
