Mola Mola Ossetra Mono Power Amplifier
SDD INTROS THE OSSETRA MONO POWER AMP…
Combining high power with extremely low noise, the Ossetra represents a major evolution in Mola Mola’s celebrated Trajectum class D amplifier technology.
High-end audio distributor Sound Design Distribution isdelighted to be introducing the Ossetra mono power amp to UK audiophiles. Marking a significant upgrade in Mola Mola’s proprietary Trajectum class D amplifier technology, the Ossetra is a 350W/8 Ohm fully-bridged mono power amplifier in the brand’s signature wave-shaped half-size chassis.
Its design, which is fully balanced from input to output, features a newly engineered power supply, a new discrete class A input stage and all new discrete class A gain stages.
The uprated power supply has allowed Mola Mola’s engineers to realise a significant reduction in noise while improving both dynamic and continuous output power, together with vastly increased current capabilities in a fully-bridged output stage, creating an amplifier which is able to drive practically any load.
The new discrete class A, DC coupled input stage, similar to that deployed by the Mola Mola Makua preamplifier, delivers a high impedance input for the source or preamp, adds gain and ensures that no DC or other signal unrelated noise enters the power stage. In addition, shunt regulators draw from the power supply the current required to dynamically meet load demands across the entire audio band while achieving superior levels of noise rejection.
Input stage distortion at approximately -150dB (~0,000003%) provides for an exemplary power stage performance involving new discrete class “A” gain stages, which generate the gain needed for the Ossetra’s high feedback amplifier design but with significantly reduced noise and distortion. An amplifier bandwidth of over 100kHz keeps the frequency response ruler flat within the audio band.
