Fidata HFAS1 Signature Network Audio Server NAS Hi-end Network AUDIO server Network Music Server 2.0TB (500GB *4) X-Cluster SSD 

 A new trend called "Network Music Server"  

However, the problem with this playback method is that the computer is between the audio systems. The

difficulty of connection and setting or the cumbersome "operability", as well as the computer that is prone to

noise, have various problems for the pure audio world. Network audio played directly from a hard disk (NAS)

set up on the network can solve this problem. The source must be concentrated on the NAS. The

smart phone or the like must be used only as a controller to directly download the sound source, and manage

and replay it. As a result, network audio has more than CD performance, and the convenience of free control.

Fidata HFAS1 is an audio-only NAS that is essential for high-quality network audio, so NAS is called a

network music server.

In combination with your favorite USB-DAC, HFAS1 is connected to the network player of the built-in server!

Connect the USB-DAC to an audio machine (single, CD player amplifier, headphone amplifier, etc.) to the HFAS1, which can be used as a built-in server for PCM/DSD to support network audio players. Use the DLNA or OpenHome Media controller app installed on your smartphone or tablet for song selection and operation.

The DAC part responsible for the sound and the controller responsible for the user interface can be arbitrarily

combined.

Those who enjoy music can further expand their enjoyment.

HFAS1  , An audio server engineered for use in high-end systems.

The fidata HFAS1 is a network audio server that was engineered so that you can enjoy high-end audio. You can see evidence of our meticulous, iterative approach from the materials chosen for the chassis to the design of the unit's circuit board and its individual components. This product is the cumulative result of numerous prototypes and countless trial listening sessions. 

The result is an exceptional level of audio quality that befits the unit's high-end name, packaged in an impressive chassis from which every hint of waste has been pared.

X-Cluster SSD unit designed specifically for audio applications

Instead of simply utilizing a single, large SSD,fidata incorporates a new technology known as X-Cluster

Storage Technology to deliver high storage capacity along with the high quality required of audio components.

Dedicated X-Cluster SSD unit for audio

The X-Cluster SSD was developed specifically for the HFAS1-XS20U.
This cluster stripes data uniformly across two SSDs. The resulting ability to access data uniformly across all SSDs in the cluster smooths the load on the power supply load by limitingdeviations in power consumption. In addition, the HFAS1-XS20U features a pair of dedicated linear power conditioners that provide clean power.

X-Cluster Storage Technology

Designers of audio devices must exercise maximum care with regard to power supplies. Featured in the HFAS1-XS20U, X-Cluster Storage Technology is a new, proprietary fidata technology developed from an audio storage perspective to deliver high SSD storage capacity, a more stable power supply, and reduced noise.

A cluster of four SSDs

The HFAS1-XS20U incorporates two X-Cluster SSD units, one on the left and one on the right, for a total of four SSDs. The result is an enormous 2 TB cluster of storage configured in a way that reduces power supply fluctuations caused by uneven data access.

Special treatment with 3.2mm steel plate greatly reduces vibration interference.

thanks to a steel chassis that’s 3.2 mm thick

The HFAS1-XS20U uses a steel plate that is 3.2 mm thick to increase its chassis rigidity. We revisited both the material and the surface finish of the base steel plate, which is 1.4 times thicker than the previous design. The new model’s hot-rolled steel features a black chromate finish, preserving the fidata’s well-received appearance while maximizing its chassis rigidity.

Linear power conditioners

In addition to the HFAS1’s power supply circuit, which consists of a dedicated switching power supply for the storage subsystem and a dedicated power generation circuit that has been tuned with numerous capacitors, the HFAS1-XS20U adds a pair of linear power conditioners for its X-Cluster SSD units. This design contributes greatly to more stable power supply performance.

Parameters

Features

1. Paired with two high-precision , high-stability 50W switching power supplies

For the high-quality playback, the HFAS1 is equipped with a dedicated TDK-LAMBDA 50W power supply unit

(total 100W) in the main unit and the drive unit. The power supply between the system part and the HDD part

is independent from the device part, thereby preventing noise from entering.

2. Dual system independent circuit module

The system part of the substrate and the stored power generation circuit are completely separated to prevent

the power supply noise generated by the hard disk from being mixed into the system. The noise generated by

the internal storage device drive recognition is completely eliminated.

3. Large capacity low distortion electrolytic capacitor

The configuration includes ultra-low ESR electrolytic capacitors with the best audio levels, each of which is

manually screened and rigorously paired to ensure optimal values. Achieve high-precision and stable power

supply.

4.  Connection separation system

Set two LAN ports for "for Audio" and "for Network". "For Audio" connects to the network audio player, "for

Network" connects to the user network, and can transmit the high-definition signals generated by HFAS1

directly to the player.

5. Use a grounding method to prevent noise generation, leakage, and mixing

The biggest problem for audio machines is to prevent noise. The HFAS1 uses a "one-point grounding

method" to optimize the layout of the line and weld the bottom base plate to the ground at a point. Eliminate

the common interface and generate a stable power supply. Keep the entire system stable, thus completely

eliminating the noise.

6. 25MHz low phase noise crystal oscillator

It is equipped with a vacuum crystal oscillator with low phase noise. It suppresses the generation of clock jitter

and achieves the highest precision network transmission with the clock action generated by the high-precision

crystal.

7. USB 2.0 interface selected by audio

By matching the power line with the acoustic grade electrolytic capacitor, the power supply noise generated

between the devices connected to the USB-DAC and the USB drive is suppressed, and high-fidelity signal

transmission quality is achieved.

8. LAN connector with excellent contact performance

Set the two LAN connectors with the signal connectors facing up to maintain stable contact with the LAN

cable lugs. In addition, the DIP type LAN connector is fixed at 14 points by firmly connecting the substrates.

Prevent loose connectors and terminals and prevent deterioration of sound quality due to vibration.
