Class D dual mono power amplifier based on HYPEX NC500 modules. Thanks to the Ncore technology the amplifier is ultra-linear, low noise and distortion (even lower than those typical of the A class or A / B of the highest quality) and also can handle the most difficult loads thanks to an ultra-low output impedance. For the dual mono design each channel has one NC500 amp board powered with one Hypex SMPS1200A700. The I/O board of each NC500 is the baseline produced by Hypex (NC500 converter) with LM4562 op-amps and LDO voltage regulators (LM7815/7915). To increase the performances it's possible to swap the LDO with the HxR voltage regulators. Balanced inputs.
NEUTRAL AND CLEAR POWER AMPLIFIER
I/O BOARD HYPEX UPGRADABLE WITH HxR VOLTAGE REGULATORS
BASIC I/O BOARD
This i / o board realized by Hypex has the advantage of not bringing any color to the audio signal.
The buffer stage uses the LM4562 op-amps with the LDO voltage regulators.
The overall gain (in combination with the NC500 module) is 26db.
The input impedance is 47Kohm.
BASIC I/O BOARD HxR
NC500 CONVERTER + HxR
It is possible to increase the performances of the basic I / O board by replacing the LDO voltage regulators with the Hypex HxRs. In this way, the following improvements are achieved:
ultra low noise
low output independent load impedance
