MUSICA C101 preamplifier
2
The C101 is substantially the evolution of the preamplifier HP01.
In C101 the circuit of signal amplification is entrusted darlington
transistor technology in configuration DPFETM (Darlington Parallel
Follow Emitter) operating in pure Class A.
The new stadiums input and output HDCA guarantee wide flat
frequency response with high slew / rate and high crest factor.
improvements on the dynamics of reproduction and micro- contrast
are to unprecedented levels.
The volume control is provided by the digital potentiometer PGA2310
Burr Brown who is currently the best potentiometer in high-end
market.
The power transformer is encapsulated with resin and thus
eliminating any possible variation of the original audio signal which
would become dirty through electromagnetic fields.
The main power capacitors are designed on our tight specifications.
They have a very high temperature coefficient and aluminum armor.
Together with the resistors in the metal film 1% tolerance and the
decoupling capacitors in polypropylene audiograde we obtained
results certainly real.,

1. For best performance, please read
this manual carefully. Keep it in a safe
place for future reference.
2. Install the unit in a cool, dry, clean
place away from windows, heat
sources, intense vibration, dust,
humidity, cold, and sources of
humming (transformers, motors,
etc.).. To prevent fire or shock hazard
do not expose the unit to water and
moisture.
3. Never open the equipment. If
something should get into all 'inside,
contact your dealer.
4. Do not operate the switches and
other controls with force. When
moving the unit, first disconnect the
power cord and cables connected to
other devices. Never pull the wires
themselves.
5. The voltage used must be
specified.
Using this product with a current
whose voltage is higher than
specified is dangerous and may cause
fire or other damage. EAM LAB is not
responsible for any damage due to an
incorrect use of the appliance
6. Always set the VOLUME control to
min. before starting playback of the
audio source. Gradually increase the
volume to an appropriate level after
playback has started.
7. Do not clean the unit with
chemical solvents: this could ruin the
finish. Instead, use a soft, dry cloth or
denatured alcohol.
8. In case of malfunction, before
concluding that the unit needs to be
repaired, consult the chapter on
"TROUBLESHOOTING".
9. If you are not using the unit for
long periods of time (eg for a
vacation), disconnect the power plug
10. During thunderstorms,
disconnect the power cord to avoid
any lightning damage the unit.
11. Grounding or Polarization: take
the necessary precautions to ensure
that the grounding or polarization are
not canceled.
Before you start to use read following information

Unpacking:
Carefully remove from the box your
amplifier and keep the original
carton and packing materials for
future trips, expeditions or long-term
storage
Before the installation :
remove your amplifier, taking care to
keep it in the future if you ever
require to be shipped to a service
center EAMLAB to be overhauled or
repaired.
package contents:
Verify that the following acessories
are included in the package:
remote control, power cord and this
manual.
Replacing Batteries
If the remote control only works
when it is near the unit, the
batteries are weak. Replace the
batteries with new ones.
Note
•For replacement use only
batteries model CR3020.
•Make sure the polarity is
correct
•For change battery
remove 4 screw in bottom
side and leave the
electronic board . battery
are bottom of printed
circuit
Use remote control
The remote control transmits a
directional infrared beam. During
operation, be sure to point the
remote directly at the infrared
sensor.
When the sensor is covered or there
is a large object between the remote
control and the sensor, the sensor is
not receiving the signals. The sensor
may not be able to receive signals
properly when it is exposed to direct
sunlight or strong artificial light (such
as a fluorescent light or a flashing).
In this case, change the direction of
light or reposition the unit to avoid
direct lighting.
Note
• Handle the remote control
carefully.
• Do not spill water or other liquids
on the remote control.
• Do not drop the remote control.
• Do not leave or put away the
remote control in the following
conditions: - High humidity or
temperature such as near a heater, a
stove or a bathroom; _ Dusty; -
Expose to temperatures very low or
very high

on the rear panel next
to the socket
No sound
Connecting signal
Input or output cables
incorrect
Check the RCA or XLR
cables and / or the
correct connection
sequence of sources
Distorted sound
The source has an
output signal too high
and preamplifier input
is saturated
Turn down the volume
of the source if it is
equipped with such
control
The signal is low
Switch XLR / RCA on
power amplifier
check the correct
position of the switch
for connecting
balanced XLR or
unbalanced RCA
Main fuse is blow
Current overload
replace with identical
fuse. if the fuse blows
again contact service
center
