Naim has gone all out to develop this integrated CDX2 optical disc player in the past few years. Recently, the CDX2 has undergone further modifications to improve its performance; in addition to providing a higher degree of flexibility, it also ensures the enjoyment of its sound quality, without compromising, comparable to analog vinyl record players.

\ \
\The obvious modification of the new CDX2 includes the installation of a switchable S/PDIF output port for external digital-to-analog converters, and a BNC connector to correct impedance matching, while also improving the performance of the internal circuit board.\
\ \
\ \
\ \
\CDX2 is a product of the same level, it contains real advanced technology, providing fun music enjoyment.\
\ \
\ \
\ \
\Super high-quality CD player.\
\ \
\Twenty current coordinators are integrated into a powerful full dual regulated power supply with excellent stability.\
\ \
\User-settable multi-function (DIN/phono) output terminal.\
\ \
\Full infrared remote control.\
\ \
\RC5 input terminal, wired remote control for complex installation procedures.\
\ \
\Optional RS232 input/output terminal for a complete set of home automation systems.\
\ \
\The optional "Name" XPS power supply provides six regulated power supplies; this greatly reduces the power supply noise of all circuits.\
\ \
\ \
\ \
\The design of CDX2 has recently been updated, including:\
\ \
\ \
\ \
\Redesigned four-layer style(Instead of two-tier)The motherboard provides better spacing and a wider range of copper surfaces.\
\ \
\New pallet board.\
\ \
\It can be equipped with analog or digital interchangeable S/PDIF output terminals. Only one output terminal can be used at the same time to ensure the sound quality. S/PDIF will be disabled when using the analog output platform.\
\ \
\Ultra-low noise pulse control.\
\ \
\Infrared-can receive modulation or demodulation input.\
\ \
\When developing the CDX2, our main design considerations focused on the integrity and stability of the RF signal read by the laser. The suspended transport and low-volume magnetic fixing system mechanism ensure that the disc rotates accurately and quietly, and is not affected by any mechanical echo .\
\ \
\ \
\ \
\A large number of customized glasses that strengthen the front loading drawer mechanism have been carefully calculated to achieve enhanced robustness and isolation. The addition of anti-vibration and anti-reverberation feet complements its elegant suppressed anti-magnetic chassis to protect its sensitive built-in components from reverberation and micro-noise vibration. In addition, we have also strengthened the internal isolation protection to improve its performance and reduce noise.\
\ \
\ \
\ \
\The route between the main components is as short as possible to protect the fragile signal, and each part of the circuit is powered by an individual regulated power supply. Every part adopts the correct grounding device, and there is no digital or headphone output port.\

HDCD decoding/digital filtering only works when playing encoded discs. Eight times the sampled data is sent to two(One per channel)Burr Brown PCM mono digital to analog converter.\
\ \
\ \
\ \
\An independent and fully optimized master pulse controls all major digital functions, and the pulse settings and layout are for mitigation. The seven-hole analog filter follows the DAC to further eliminate spurious noise.\
\ \
\ \
\ \
\CDX2 is equipped with a comprehensive dual regulated power supply. Its main board is equipped with 20 low-noise regulated power supplies, while the servo control board and display board use individual power supplies. This is an all-in-one machine started by the main power supply, and can be used with XPS ultra-low noise power supply to greatly improve its sound quality.\
\ \
\ \
\ \
\The research work of "Ming" confirms that separating the disc player from the main power supply will achieve excellent results, and "Ming" XPS power supply is a very precise power supply with six independent regulated and ultra-low noise outputs. Equipped with toroidal transformer and six power supply regulators. This ensures that the ultra-sensitive circuit in the CDX2 is completely stable. The same external power supply is also used with the "Name" CDS3 CD player, opening up another way for users to upgrade to other players.\
\ \
\ \
\ \
\All the main control functions are processed by the microprocessor running the software written by "Name". Every aspect of the SAA 7324 servo controller/decoder is controlled by this software: The code written by "Name" optimizes every aspect of performance. For example: when reading each disc, its transport parameters are optimized.\
\ \
\ \
\ \
\We have carefully ensured that the CDX2 player/user interface is as logical as possible, while also providing additional features: such as turning off the display(Can improve sound quality)And cancel the program, allowing users to quickly filter out the audio files they don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t like to listen to.\
\ \
\ \
\ \
\We have incorporated some excellent user functions: In addition to the clear rear panel layout, we have also added an RC5 port and an additional RS232 port, so that complex household equipment can also be seamlessly matched.\
\ \
\ \
\ \
\CDX2 and the flagship CD555 music CD player also have user-configurable output terminals, allowing users to choose DIN and RCA output terminals, so that CDX2 can be connected with cables and parts made by other manufacturers.\
