USEFUL INFORMATION
JMH is a class D amplifier with a final stage that offers a
maximum power of 60W RMS on impedance of 4Ohm. Small,
light, compact, it integrates a pre-amplifier in JFET technology.
The reasons that led me to use this formula are focused on the
musicality of the product and the great feeling of similar use in the
response to the most famous tube amplifiers.
THE PRE-AMPLIFIER in "cascode" technique proposes an
amazing linearity of signal useful to guarantee great benefits of
interfacing and transparency of the signal to other units.
TONE CONTROL includes three passive filters that act on the
frequencies: 80Hz (low); 560Hz (middle); 5500Hz high.
POWER STAGE employs a class D digital module with PBTL
configuration. Although the connection of a speaker with an
impedance of 4 to 8Ohm is possible. The best performance of
power and linearity can be identified in 4Ohm.
CAUTION!! the bridge ending provides exclusively direct
connection to the cashier (NO NEGATIVE SPEAKER TO GND)
ALL AUDIO CONNECTIONS ARE: 6.3mm MONO JACK.
The Guru advises:
Use a "speaker" cable to connect loudspeaker with a minimum
cross-section of 2X1mm. up to 5 meters.
The recommended power supply to guarantee the correct
performance is with 24Vdc voltage (central positive) with 3
Ampere working current.
JMH is a guitar amplifier not a pedal effect: be very careful to
connect the "SPEAKER" output only and exclusively to a
speaker cabinet. Never connect the "SPEAKER" output to an
input of another amplifier, pedal effect, mixer, computer, or similar
units.
