Yulong D200 DSD 32bit 384kHz DAC Decoder Headphone Amp

Thank you for choosing Yu Long D200 DAC and headphone amplifier. We believe this product can bring you a whole new experience in the world of music.

This ultra high performance to cost ration, 32bit 384KHZ DSD DAC is developed based on our highly acclaimed Sabre DA8. It comes with simplified operation, compact yet detailed construction, and a full set of interfaces: USB, TOSLINK, SPDIF and AES for digital inputs, and XLR, RCA plus 6.35mm headphone out for its application flexibility.

Further to its first class measurement performance, our sound optimizing team, which is formed by senior hifiers and  professional music industry experts, has spent enough time to fine tune the sound. The result is a perfect balance between  dynamic, resolution, and fullness. It is optimized for all kinds of musics.

D200 utilized ESS9016 as its heart, accompanying OP275 as LPF, OPA1632*2 as buffer and preamp. Headphone output is high current class A design constructed with MJD243/253 transistor with a output short circuit protection. High quality power supply includes Canadian Plitron toroidal transformer and 10 ways independent regulations. All Components are decided by extensive listening test. There is a unique digital shaping and buffer design to improve the digital signal quality. Furthermore, an ultra low phase noise oscillator combined with DPLL automatic frequency switch make a very reliable clock. 

There is a jitter filter which is can be set on (for lower quality digital signals) or off (for high quality digital signals) to best fit your equipments.

The LCD display, together with LED indication light make the operation easy and intuitive. The LCD dims 80% after 5 seconds idle. User settings are auto saved. And you can choose from 2 filter modes and 2 jitter eliminator modes to mix match a sound character you like!

 There is a 80 step volume control, which is a perfect simple set up for studio monitor users. You can turn the pure DAC mode on, which will bypass volume control and shut down headphone amplifier, for a ultimate DAC performance

The USB solution is based on Xmos U, featured 3 low phase noise oscillators in asynchronous mode. It supports DSD and  PCM 32bit 384KHz, and compatible with Mac OSX, Linux and Windows.

1 .LCD display shows the modes. Auto dim after 5 second idle.

2. Input selection. Cycles between Spdif, toslink, aes, usb when pushed. Sampling frequency will be displayed on LCD when signal is locked. DSD logo will be shown when a valid DSD signal is detected.

3.Digital filter mode selection. The default sharp mode has a flat response. When the LED lights up, it is in slow mode which has a slow roll off in high frequency (it is not functional in DSD mode)

4.Jitter eliminator selection. It is bypassed when LED lights up, and sound is tend to slower and softer. When it is on, the sound tend to more focus. However depends on the equipments, you may not hear a difference. 

5.Headphone out. 

!!! Warning: The headphone jack on D200 is VERY tight, please make sure the headphone plug is fully inserted. In case of not fully inserted, the left and right outputs are shorted and will damage the headphone amplifier! The short circuit can not prevent this situation!!! We don't honor warranty to damage under this situation!!!!

!!! Warning:Please turn the volume to minimum before connecting or turning on equipments. It may sound dangerous loud!

Tips: When in pure DAC mode, the headphone amplifier is shut off - however you may still hear minor sounds from the headphone jack. It is normal.

6.Volume control, turn to change output level in 80 steps. It controls all outputs. Press the volume knob for 1 second to change D200 into pure DAC mode. Volume control and headphone amplifier are bypassed in pure DAC mode.

!!! Warning: D200 outputs a full scale signal in pure DAC mode. You must have a volume control in your system, otherwise the output level could be dangerous high, and might permanently damage your equipment and hearing!!!! You may also face angry family members, neighbors and pets! We don't response to any damage under such condition.

7.Unbalanced analogue audio output

8.Balanced analogue audio output. It has an extremely low output impedance, and you can use it as a balanced headphone amplifier. Volume control must be turned on for such application, otherwise the headphone and your hearing may be permanently damaged. We don't response for such damage.

!!! Warning: Do not use regular XLR-RCA conversion adapters or cables , which normally short pin 3 to ground. You will damage the output stage!!! We don't response for such damage. Make sure pin 3 is disconnected if you want to use the balanced output as unbalanced.

9.Spdif coaxial digital input

10.Spdif toslink input

Tips: Some quality equipments have a poor digital signal quality, and might cause malfunctioning under higher bitrates. 

11.AES/EBU digital input

12.USB input. You must install driver for Windows system, and please download from /en/down.asp. 

You must make sure the playback software can self adopt digital file sample rate. ASIO and WASAPI is preferred. Play back software must support DSD mode doe DSD and SACD playback. When valid DSD signal is detected, the LCD will display input USB DSD

13.Voltage selection. 

!!! Warning: Please make sure you choose correct voltage before connecting to mains power. Otherwise you may permanently damage D200 and your equipment. We don't response for such damage.

14.Mains power socket, power switch and fuse box. We include a back up fuse in the fuse cpmpartment.

Tips

Please let D200 warm up for at least 15 minutes for its best ability

Please make sure the air circulation - D200 is warm because of the design.

Please use high quality USB cable. Don't connect D200 via a USB hub, or extension cable (for example most USB ports in the front of tower case). Connect to the one directly on motherboard.

Make sure the mains power's grounding is working. Otherwise there might be a noise.
