Product Introduction ▼


 

• Overview of HUD-mini
HUD-mini was developed to realize sound quality that could be attained from Hi-Fi audio equipment only by connecting to USB port of notebook or desktop PC. It has simple and elegant design with easy installation and mobility using external USB DAC, and it was designed as high performance Hi-Fi audio equipment internally applying integrated design to the maximum in small space to make best performance in spite of compact size.

 

• Reproduction of High Quality Sound of 24 bit/96kHz 
It can reproduce high quality sound source of 24 bit/96kHz without any loss by the adoption of updated Vinyl EnvyUSB 2.0 Audio Controller of VIA, and it can display high resolution and Hi-Fi level of audio quality by the adoption of Ti PCM1791A with 24 bit/192kHz specification. Equipped with Highest Grade of OPAMP and High Performance Headphone Amplifier 

It realized high performance and high fidelity audio with very low distortion of THD+N 0.00003% and ultra low noise by the adoption of LME49860 of National Semiconductor for DAC output stage. Also, you can enjoy sufficient sound volume using the headphone of less than 300Ω by the adoption of AD8397 of Analog Device. High quality audio signal which is generated through high-level components is applied to speaker, earphone or headphone as it is providing Hi-Fi level of audio environment.
 

• Equipped with LDO Regulator of High Performance and Ultra Low Noise and Inverter Circuit for Power Stage 
Positive and negative voltages are required to drive high performance OPAMP of dual power type. After the rectification process of USB power supplied via USB port to stable power without noise through LDO regulator and Low-ESR capacitor, the best analog signal with ampleness and density which can be attained from high-end equipments can be created by the provision of consistent dual power to OPAMP circuit via high performance inverter.

 

• Application of high purity TCXO on Clock Generator of USB Controller

 

• Application of high performance ALPS potentiometer on headphone output volume controller

 

• Application of high grade film capacitor of WIMA on a low-pass filter terminal

 

• A total of five special purpose regulators, high performance low-ESR and many tantalum capacitors are applied for supplying stable and high quality power. 

 

• The DAC power terminal is applied with high performance solid capacitors of super low-ESR & high ripple current.

 

• A highest quality metal film resistor of Vishay-Dale applied for high-end audio equipment is adopted. 

 

• DDC function is mounted capable of outputting a USB digital audio signal to the S/PDIF (Optical TX).

 

• 88. 2 kHz is supported that is not supported by most of the USB Audio DACs.

 

• An anti-POP circuit is mounted for removing unnecessary noise generated when power is turned on and off.

⑥ Optical Out (S/PDIF Optical-Out)  
PCM output can be utilized, and can be connected to a receiver amplifier having an optical input function via an optical cable. 
※ A driver to use AC3 pass-through function is activated on the hompage, you can set it on the player.


⑦ USB Port
Connect to USB port of your computer using a bundled USB cable.

 

⑧ RCA Output
Connection to the speaker (amplifier) is made using an RCA cable.

Connecting the Hardware and Utilization ▼


 

 

• Connecting the Hardware and Utilization in Mac OS X
No driver installation is required. HUD-mini will be automatically recognized as USB AUDIO device shortly it is USB-connected to your computer. Then you can enjoy HUD-mini shortly.
System Configuration → Sound, HUD-mini will be registered automatically.

Sample format and bit quality can be changed in the audio MIDI set-up as per the following:

 

07.jpg

 

• Connecting the Hardware and Utilization in Windows XP 
When HUD-mini is USB-connected to your computer, Windows basic USB AUDIO driver will be automatically installed, showing `New hardware Detected` message. [Control Panel] – [Sound and Audio Device] – [Audio], Audinst HUD-mini will be registered automatically. Then you can enjoy HUD-mini shortly.

 

 

• Volume set-up of windows volume mixer

Preferably, volume of windows volume mixer is advantageously set up at a maximum level for sound quality. However, in case of using an ear phone or head phone having a low impedance, an adequate sound volume must be obtained for use through adjustment of volume of windows volume mixer and analogue volume controller.

Cautions when Exchanging OPAMP ▼


 

HUD-mini is replaceable with LME49860 OPAMP of National Semiconductor as a replaceable socket type, such that you may replace OPAMP according to your musical choice. When replacing the OPAMP, use a Phillips screw driver to separate PCB of HUD-mini from the case, pull out the existing OPAMP from the outlet, and mount a new OPAMP to the empty outlet as shown in the picture, where directions of the OPAMP and groove of the outlet must be correctly aligned.

Caution: OPAMP replacement must be performed while connection between HUD-mini and USB cable is disconnected, and OPAMP set-up direction, use standard and driving voltage must be checked in advance. 

 

• Careful attention is needed in set-up direction when OPAMP is to be replaced. Damage and/or functional failure to the product caused by installation of improper OPAMP, erroneous and/or wrong insertion of OPAMP may prevent you from receiving a free repair or service even within a warranty period, such that you are required to carefully replace or install the OPAMP. 
 

• OPAMP standard useable for HUD-mini: DIP Type & Dual Type(Stereo) OPAMP (SMD type is useable by conversion from SMD to DIP, and single type is useable by conversion from single to dual)

 

• OPAMP driving voltages are indicated as minimum driving voltage and maximum driving voltage on website data sheet of relevant manufacturer. ±5V of HUD-mini are supplied to the OPAMP circuit, and check, before installation, whether the voltage is between the minimum driving voltage and maximum driving voltage of the OPAMP to be used.

 

ex) LME49860 : Operating Voltage ±2.5V to ±22V    →  Useable
MUSES01  : Operating Voltage ±9V to ±16V       →  Un-useable
MUSES02  : Operating Voltage ±3.5V to ±16V    →  Useable
