The new Morel MPS 1.550 - Monoblock amplifier provides a unique feature set and installation-friendly design. The MPS 1.550 uses a single-sided circuit layout with all connections on one side of the amplifier, making installation simple and clean. Preamp tuning and setting options are located discretely under a removable panel at the top of the amplifier.
The amplifier is also devised to integrate with OEM audio systems directly through the RCA input with an adaptive connector, and auto turn-on via signal sensing or DC turn-off sensing—features usually found in much more expensive amplifiers.
The MPS amplifiers set new sonic boundaries for affordable amplifiers and a unique feature set that places them at the top of their game.
- The MPS incorporate fully balanced differential inputs that provide superior noise rejection and can endure up to 20 volts of signal input, allowing even factory speaker-level signal to be accepted through the RCA connections.
- High fidelity Texas Instruments OP amps and ultra-low tolerance surface mount components keep the integrity of the audio signal as pure as possible.
- Protection and thermal management are managed via an onboard microprocessor, allowing our engineers to design the amplifier without the need for internal fuses that can impede power delivery to the power supply.
