EA’
S QUALITY CONTROL
To ensure your iAMP
®
meets its rigid design specifications:
•
Every board is pre-tested before it is installed into the amp.
•
Post assembly, each iAMP® is bench-tested before its burn-in phase.
•
Each unit is burned-in (turned on and allowed to sit
“in
idle”).
•
Each unit is individually tested with a bass and speaker cabinets.
Additionally, the preamplifier section uses state-of-the-art surface mount components
and construction techniques for lower noise and better reliably. These extensive and
time consuming procedures guarantee that E
A’
s production units are of a consistently
high quality. Careful packaging helps ensure safe transport to the customer.

WARNINGS USED ON THE EQUIPMENT
WARNING
–
ATTENTION
OUTLETS WITH A THIRD PRONG GROUND ARE
REQUIRED. DO NOT USE WITHOUT A GROUNDING PLUG.
WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT
EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.
The lightning flash symbol is intended to alert the user to the
presence of uninsulated
“dangerous
voltage”
within this
product’
s enclosure that may be of sufficient magnitude to
constitute risk of electric shock.
The unit contains no user serviceable components, under no circumstances should
the unit be turned on or plugged in with the top cover removed.
The exclamation point is intended to alert the user to the pres-
ence of important operating and maintenance (servicing)
instructions in the literature accompanying this product.
GROUNDING INSTRUCTIONS
This product must be grounded. If it should
malfunction or break down, grounding provides a path of least resistance for
electric current to travel, which will reduce the risk of electric shock. The product
is equipped with a power cord having an equipment grounding conductor and
a grounding plug. It must be plugged into an appropriate outlet that is properly
installed and grounded in accordance with local codes and ordinances.
DANGER
Improper connection, lack of connection, or modification of the
equipment grounding conductor can result in a risk of electric shock. Check with a
qualified electrician or serviceperson if you are in doubt as to when the product is
properly grounded. Do not modify the plug provided with the product if it will not
fit an outlet; instead, have a proper outlet installed.
Make sure that the speaker connections and AC power connections are both
properly made before powering on the amplifier. Likewise, power off the amplifier
before disconnecting the speaker connections and before removing the AC power
cord from the rear connecto

EFFECTS SECTION
The default setting for the Effects/Tuner Send and Return makes it available on
Channels 1 and 2 (see
“A
Look
Inside”).
Via jumper settings the Effects/Tuner Send
and Return can be available on both channels. This can be changed as a custom
configuration only.
Parallel Effects/Tuner Send Jack:
Connect the
cord going to the effects box, pedal or tuner
here.
Dry/Wet Control:
Use this control to adjust the
level of the signal returning from the effects
chain.
Footswitch:
An optional mono or dual momentary footswitch can be plugged into the
footswitch jack. When using a mono footswitch you will be able to control the IIS
channel switching function as you would with the front panel switch. When using a
dual momentary footswitch (with a stereo plug) you can additionally control the mute
function as you would with the front panel switch. The footswitch does not disable
the front panel controls; rather they continue to work in parallel and picks up where
one leaves off. With a dual footswitch the
“tip”
controls the IIS while
the “ring”
controls muting functions. The configuration of the Footswitch is handled by
S7. See
“
A Look Inside
”
for specific jumper settings. The factory default setting is for a
mono footswitch.
REAR PANEL FUNCTIONS
INPUT SECTION
Source:
Two, 1 MEG Ohm, instrument inputs designed for maximum flexibility for all
musical instrument applications. On channel 2, one optional low impedance Microphone
input with phantom
power may be used in place of the ¼” instrument input.
IIS or Intelligent Input Switching, which can be actuated from the front panel or with
an optional footswitch, is a microprocessor controlled CIRCUIT that senses which
channel is activated and allows for different combinations of channel control. With
your bass plugged into channel 1, the switch will let you access the EQ on channel 1
or channel 2 (i.e. clean/solo). With basses plugged into channels 1 and 2, the IIS will
toggle between Channel 1, Channel 2, or both Channels 1 and 2.
Level Indicator Yellow LED
: The Level Indicator LED is a visual representation of
your input level. The LED should illuminate moderately under normal playing
conditions. Input gain can be adjusted with the Gain control knob.
Gain Knobs
: The Gain knobs allow for maximum signal level and headroom. Gain for
each channel can be adjusted by the Gain knob located on top of the amp.
Power Switch:
Turns unit on/off.
A/C Input:
Use appropriately grounded, three-prong A/C plug.
Speaker Output:
One Speakon connectors, wired 1+, 1-.
Cooling Vents:
The vents on the top and sides of your Micro or Doubler need
to be kept clear.
Using the Gain Knobs:
The yellow LED for each channel
should illuminate moderately under normal playing
conditions with the gain knob about half way up
