POWER OUTPUT
The eM-2002 features ballistically-
weighted power meters that are calibrated in
decibels. The main dB scale has a top value
of +3dB, with OdBequal 100 watts per
channel into 8 ohms.
The meter ballistics include a fixed
amount of overshoot, the needles can move
past the OdBlevel when played loud.
On some musical material, the amplifier
could be reaching its maximum power even
though the meters aren't reaching full scale.
Operation
The front panel power button will turn
the eM-2002 ON or OFF.
$~ When this is pushed in, the
I!!...
standby light will flash for a
p""""
few seconds until the eM-2002
OWE:R
is ready for use.
Gl
When it is pushed out, the
eM-2002 is OFF,and it will not
respond to the remote control.
Then, the only way to turn it
ON is by pushing the button in
again.
--
If the eM-2002 is ON and you use the
remote control power button to turn it OFF,
it will go into the standby mode. There will
be no power to the speakers and all the lights
will go out except for the standby light. The
eM-2002 will respond to the remote control
power button to turn it back on again.

This is because the meters are indicating the
average
power output. Momentary musical
peaks can drive the amplifier to its
maximum output for brief periods, faster
than the meter needles can respond.
The best way to tell whether the amplifier
is overloading is to listen. If the sound
becomes distorted on musical peaks at the
same time the meter needles are "pegging",
you have probably exhausted the eM-2002's
power reserves. If this occurs, you should
reduce the volume level.
A typical listening session would be as
follows:
1. Turn on vour Cl), Tape decks, etc.
2. Turn down the volume control and push
the front panel power button in.
3. Play your Cl), Tape, etc and adjust the
volume as desired.
4. When finished, you can use the remote
control to turn off the eM-2002, by
putting it into standby.
5. The Standby light will stay on, indicating
that it is ready to be turned on at any
time.
6. If you have finished listening for the day,
you should press the front panel power
switch to turn it off. This is a precaution
in case of power surges during the night.
