DESCRIPTION
Class D mono power amplifier based on the HYPEX NC500 with the ultimate Ncore technology. The amplifier is ultra-linear with very low levevels of output noise and distortion (lower even to those of the highest quality class A or A / B power amplifiers). The ALAUDA MB-2 can drive the most difficult loads thanks to an ultra-low output impedance. The power supply is the Hypex SMPS1200A700 board with a filtered EMI/RFI main input load. The i / o board is the high performance ROUGE NCX2 which allows the choice between operational IC (OPA1612) and discrete op amps, adding HxR voltage regulators and monitoring of the amplifier status (on-ready-clip). Balanced and unbalanced input connectors.
NCX2
This power amplifier is equipped with the NCX2 i/o board which offers the possibility of adding discrete op-amps and voltage regulators.
The NCX2, in default, always uses the OPA1612 in the buffer stage, perhaps among the best IC's on the market for transparency and clarity of sound (without adding color), whose power is entrusted to the small and fast TI TPS7 voltage regulators ( LDO).
Basically, therefore, the same circuit as the previous NCX.
The new feautures, which makes NCX2 unique, is that it is nevertheless designed to add a discrete op-amp on DIP8 and the Hypex HxR audiophile voltage regulators.
This "addition", however, does not replace the default setting of the circuit and its basic components (OPA1612 + TI TPS7) since, by moving the appropriate jumpers on the board, the user can always choose and select in any moment the combination (operational-voltage regulator) he prefers:
-
OPA1612 with TPS7 voltage regulators,
-
OPA1612 with HxR voltage regulators,
-
discrete components operational with TPS7 voltage regulators,
-
operational components with discrete components with HxR voltage regulators.
