UR OBJECTIVE
was to create a compact, full–featured
integrated bass amplifier with a wide bandwidth,
possessing more than adequate power and exceptional
“headroom”
(for extra power demands, when needed),
an amplifier
capable of driving and extracting all the nuances from EA’s expressive line
of speaker cabinets. Our overall design mandate included balancing between two
competing ideals: simple to use, yet extremely flexible.
We took our cue from today’s high–end recording studio equipment, thus creating a
robust integrated amp with an intuitive layout, providing today’s bassist with
exceptional versatility. Notice the “organic” placement of the controls on the Front
Panel. As the signal flows from left to right—from the

ECTION
ACTIVE INPUT:
Low Impedance (Low Z) 10K ohms, optimized for active systems (basses
with internal power pre-amps, i.e., those that use batteries).
PASSIVE INPUT:
High Impedance (High Z) 1meg ohm, optimized for piezo, and/or passive
systems as well as active basses which have low to moderate output levels.
STEREO IN:
This feature allows the input of an outside signal other than the primary
instrument such as a CD player or Drum Machine.
FIRST STAGE OVERLOAD INDICATOR:
A red warning light indicates when excessive input,
dangerous clipping or distortion levels are being sent into this critical first stage of the
iAMP800. Occasional peaks which illuminate the overload LED are not dangerous.
INPUT LEVEL METER:
Used in conjunction with the rotary LEVEL CONTROL (see below),
this 5 LED bargraph helps you monitor the input level into the TONE SHAPING section.
LEVEL CONTROL:
Set this control so that 2–4 LED's illuminate under normal playing
conditions with any tone controls engaged. It is not necessary to light all the LED's to achieve
maximum performance.

POWER SWITCH:
Turns unit on/off.
A/C INPUT:
Use appropriately grounded, three-prong A/C plug.
FUSES:
For 115V, use T10A 250V fuse. For 230V, use T6A 250V fuse.
SPEAKER OUTPUTS:
Two Speakon connectors, wired 1+, 1-.
VOLTAGE SELECT SWITCH:
Use this switch to select 115V or 230V 50/60Hz power source.
COOLING VENTS:
Your iAMP800 is so efficient it needs no cooling fan. Although the
iAMP800 needs no fan, the vents on the side, back and bottom need to be kept clear. If you
are putting your iAMP800 in a rack, consider a 3-space rack for adequate ventilation.

To ensure your iAMP800 meets its rigid design specifications:
■
Every board is pre-tested before it is installed into the amp.
■
Post assembly, each iAMP800 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 Euphonic Audio’s production units are of a consistently
high quality. Careful packaging helps ensure safe transport to the customer.
