PRECAUTIONS
You may seriously damage any transistorized audio
unit by being careless when you first operate it. Care-
lessness is the maior cause of audio repairs. Avoid
disappointment by following the precautions listed
here BEFORE plugging in or attempting to operate
your EM-150.
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.
U.S., Canadian, European and Australian models are
set to the proper voltage before shipment.
e Make sure the power switch is off before plugging
in the power cord.
e Unpiug 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.
e Be sure there is sufficient space around, behind and
under the unit for proper ventilation.
e Do not switch input selectors while the amp is
in use.
REAR PANEL PARTS
O Monitor Out Jacks
Use these jacks when feeding the mixed signal to
a combination amp/speaker (music amp) unit for
extra power (for large hall performances, etc.).
Q 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.

CONNECTION DIAGRAM
Extra Channels with a Second Unit
A second unit can be connected for extra channels
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.
{В} 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.
If you wish a separate volume control independent
of the Master Volume, use (A) connection; if you
do not, use (B).
FRONT PANEL PARTS & CONTROLS
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.
O 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.
O Input Jacks
OQ VU Meters
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. Qut
jacks. If the level is so high that the needle on
either or both channels exceeds +3, sound distortion
will result.
O Graphic Equalizer
There is 7 Band Graphic Equalizer (+ 12 dB) for
each of the seven separate controls: 60, 150, 400,
1k, 2.5k, 5k and 10kHz. You can obtain optimum
frequency response in any location by adjusting
this control. If howling occurs, this control can
serve as a howling suppressor by towering the level
of selected frequencies.

jacks going to the Speaker and Phones outputs. The
volume is independent of the other volume controls,
including Master Volume.

® Monitor Volume Control
Controls the combined volume of the signals from
all the channels going to the Monitor Out output.

from all the channels going to the Speaker and
Phones outputs.
