Cicognani Engineering JMH Class D 60-Watt Amplifier
Small, light, compact, it integrates a pre-amplifier using jFET technology. The reasons for this combination are focused on the musicality of the sound and a feeling of use that is similar in response to the most famous tube amplifiers.
The pre-amplifier in “cascade” technique offers an amazing signal linearity that provides transparent interface with various pedals and speaker setups.
The Tone section consists of three passive filters that act on the frequencies: 80Hz (low); 560Hz (middle); 5500Hz (high).
The JMH power stage employs a class D digital module with PBTL configuration. Although the connection of a speaker with an impedance of 4 to 8 ohms is possible, the best performance of power and linearity can be achieved at 4 ohms.
