FEATURES
AUTOMATIC VARIABLE SPEED FAN Values shown are for converted chip
levels to within 100W based on actual
measurement data for each amplifier.
New model L-Series are high efficiency
amplifiers with new special design.
New L-Series high power amplifiers make
more efficient use of the AC power more
than conventional amplifier technology.
Also new EIC (electronic Improved Circuit)
engine consumes power efficiency, which
allows the amplifier to produce the same
amount of output power with about half the
input power required and heat loss about
comparing that of conventional amplifiers.

The EIC engine outperforms other
efficiency-enhancing schemes without
degrading sound quality by digital power
supply.
This apparatus should be serviced by qualified service person.
Read all safety instruction before operating the L-Series amplifiers.
1. Install equipment as follow conditions.
Install at the place, not bending curved.
Do not install this apparatus in a confined space such as a book
case or similar unit.
The apparatus shall not be exposed to dripping or splashing and
no object filled with liquids, such as vases, shall be place on the
apparatus.
Locate this apparatus away from heat source, such as radiators
or other device that produce heat.
Do not drop objects or spill liquids into the inside of the apparatus.
2. Keep in mind the following when connecting the apparatus.
To prevent electric shock, do not open top cover.
Connect the power cord with safety after check of AC power.
Connect the apparatus after reading of O/P manuals.
Connect each connection of the apparatus perfectly, If not, It maybe
caused hum, damage, electric shock in case of mis-connecting.

2. CHANNEL A, B
3. POWER, PROTECT LED
For the bridged mono, parallel, operation, volume control can be
adjusted by channel "A" adjust channel "B" to the counter clockwise.
4. POWER SWITCH
Provides power to the unit
1. To avoid loud switching noises, always switch on the power
amplifiers in an amplifier system after all other units have
been switched on.
2. At first, turn the volume fully counter clockwise, then with
approx 2~3 minutes be for switching off.
Turn "0dB" on LED indicator is normal operating.
Adjust volume when CLIP/LIM indicator is lighting continuously.
After switch on for approx 3 seconds. (in rush current)

Power LED on the channel A,B is turn on, when supplying
power to the amplifier.

3. OUTPUT CONNECTORS
Turn the amplifier off before touching the output connection.
the amplifier with any of the conductor portion of the
lengths minimize both loss of power and degradation
of damping factor.
Minimum output operation of amplifier is 4 , 8 .

WARNING: To prevent electric shock, do not operate
SPEAKER CABLING: Larger wire sizes and shorter
Feed up signal to the input "CHA" only parallel mode is for

FULL RANGE
This is for seriate operation per channel sub woofer, x-over
will not be operated.
Permissible adjustment of low cut.
Variable frequency(50~160Hz) by one volume.
Specification of filter -12dB/octave is for subwoofer speaker
mainly.
X-OVER(BI-AMP)
Permissible power supply to input "A" channel connect woofer
speaker to the "CHA" and connect high range speaker to the
"CHB".
It designed -24dB/octave variable frequency.(50Hz~2.5kHz)
LOW CUT
This is to protect speaker from damage by large ultra frequency
or blowing of voice coil, low it designed -12dB/octave variable
frequency.(10~200Hz)
6. MONO OUTPUT
Output connector supplying input CH"A, B" balanced output
connector.
It is convenient to use for sub woofer speaker only.
LIMITER SWITCH
This switch is for grounding between circuit ground and chassis
ground to avoid problems like a electrical potential difference.
When the audio signal drives the amps output circuit beyond
its power capability it clips flattening the peaks of the waveform.
The clip limiter detects this and quickly reduces the gain to
minimize the amount of overdrive limiting occurs only during
actual clipping. Each channel has its own clip limiter and you
can switch it on or off independently.

Wiring the following instructions describe the most common
ways to install your amplifier into a sound system.
1. First, turn off power switch befor connection.
2. Refer to wirning diagram for speaker connection.

3. L series amplifier maybe operated in one of three modes
4. JEDIA assumes no liability for damaged loads resulting from
careless amplifier use or deliberate over powering.
How to connect stereo(2-CHANNEL) MODE
connect the output wiring as shown.
To put the amplifier into stereo mode, first turn the amplifier off,
then slide the stereo-mono switch toward the left, and properly
