– XiangSheng DAC-01A DAC Decoders/Headphone/PreAmplifier
– Model: DAC-01A Improvement – Dimension: 260mm (W) x 55mm (H) x 167mm(D). – Net Weight: 2.5KG. – Input: 5 Input (1 USB, 1 Coaxial, 1 Optical, 2 Analog RCA). – Output: 3 Output (1 OP Amp, 1 Tube, 1 Headphone). – Headphone Mode: (OP Amp + Buffer Amp). Improve the driveing Curreunt. – Sampling Frequency Rate: (32K, 44.1K, 48K, 88.2K, 96K & 192K). – Sampling IC: CS8416, CS4398. – Transformer: R-TYPE (See photo). – Output OP Amp: OPA2604 x1, LF353N x2. – Output Tube: 6N3. – Panel Color: Sliver or Black. – AC: 110V – 230V which is a small control center: up to 5-way audio input, whether it is a DVD player, CD player, computer, HD player, TV set-top boxes, MP3 (MP5) player, HD HDD player, IPOD and so on, whether digital or analog signals, you can select the input connected to the machine, the machine simply switch knob on the front panel one can get, do not need to unplug the signal line in exchange for going. Greatly simplifies the operation is very convenient. This makes the machine more than just digital decoder, and detached to become a multi-function control center. New and improved DAC-01A upgraded version : First, the improvements : 1, the digital receiver chip used by the U.S. company CIRRUS CS8416. It is currently supporting 24bit, 192KHz most widely used of a chip. 2, the decoder chip used by the U.S. company CIRRUS CS4398, this chip high targets have been introduced a lot, do not waste space and then repeat. This machine is good but the frequency resolving power for CS4398 features designed thin section IV conversion parameters . 3, USB transfer spdif by the upgrade QFP48 package CM102 CM108. When connected to the computer USB port on the motherboard inside the indicator light flashes when playback is used to check the USB chip is working properly. 4, the high cost of R-type transformer power supply , the price is circular, square transformer price multiples , multiple independent windings , multi-stage regulator filtering. Analog, digital power supply independent , analog, digital and independently . 5 , the upgrade version with Philips, Samsung , TDK, Yageo brand chip RC parts, coupled using seven red Weimar Germany WIMA capacitors , etc., so that the sound quality can be guaranteed. 6 , using three pairs of op amp to do the IV conversion , respectively , buffered isolation , pre- amp . 7, the upgraded version of the PCB board using military grade A material production, insulation , stability , pressure and better performance. 8 , the machine default volume control only headphones, line output signal controlled if required , please explain the time of purchase . Otherwise pays shipping amend , or modify. 9 , the machine ‘s volume potentiometer is 148 diaphragm type customization Taiwan , reaching ± 1.5dB (ALPS is only ± 3dB), long life, good symmetry . 10 , can actually support up to 24bit, 192KHz. Found an upgraded version supports the following sample rates : 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4K, 192K.
