Design Features We are proud to Introduce the DAC-2 DSD and SE. During development of the original DAC-2 we recognized that digital streaming technology was progressing at a very fast rate. We created a modular circuit design which would permit future upgrades as the industry progressed, and we can now deliver that promise! The newly refined DAC-2 DSD includes upgrades to the USB interface and digital processing circuitry.
With an oversized toroid, more than 115,000uF of capacitance, 3 stages of filtering and 13 regulation points, the power-supply in the DAC-2 DSD is surely overbuilt. The analog output stages are powered by a separate power-supply to ensure isolation from the digital front-end. House-keeping voltages also use separate supplies to guarantee minimal supply contamination. The digital board is supplied with 7 out of the 13 dedicated regulators to ensure tight tolerances, and consistent power delivery.
Setup Menu With a quick look at the setup options, you will quickly see how flexible the DAC-2 DSD really is. Each type of input can be configured to fixed or variable volume control, and you can also independently choose the level of each. Min/Max volume levels are also adjustable for each input to offer optimal flexibility for those low or high sensitivity systems.
• Toslink Maximum Volume level (0-70) • • • USB Volume select (Variable / Fixed) USB Minimum Volume level (0-70) USB Maximum Volume level (0-70) • • • AES/EBU Volume select (Variable / Fixed) AES/EBU Minimum Volume level (0-70) AES/EBU Maximum Volume level (0-70) • • • • I2S Volume select (Variable / Fixed) I2S Minimum Volume level (0-70) I2S Maximum Volume level (0-70) Discrete Input (On / Off) Front panel operation The front of the DAC-2 DSD offers several features.
*Please Note: Dim settings accessible from the remote* -The DAC-2 DSD se: (Constant ON / Automatic OFF after 2 seconds of no input from remote) -The DAC-2 DSD: (High / Med / Low / Automatic OFF after 2 seconds of no input from remote) USB Configuration The USB interface of the DAC-2 DSD is driverless for Mac systems 10.6-10.9 as well as Linux. The included driver disk has standard drivers as well as ASIO drivers for Windows XP, Vista, 7, and 8.
6. Once the install process has begun follow the on screen instructions. The install wizard will prompt you when the process is complete. If you require more detailed instructions please visit the FAQ page of our website. 7. Connect the DAC to your computer with the supplied USB cable, power the DAC on, and select the USB input. You may be prompted by an install wizard that additional installation steps are required. Follow the on screen instructions.
HT Bypass mode: When the setting under “TRIG” is Off, then the HT Bypass on trigger-in is active. There are a pair of analog inputs (inner most pair of RCA’s) that should be connected to the pre-outs of a surround sound processor to be switched in to bypass the DAC circuitry when in HT mode. When either the HT input is selected, or the trigger input is activated, the HT inputs will be directly connected to the DAC outputs.
remote control if you plan on using the DAC with other W4S products that offer the same features such as the STP or STI products. This will eliminate any interference between the units when the remote is used. Note: For the fixed mode to operate properly, you must set the Min level for that input to (0). Bandwidth / IIR settings There are several settings in the setup menu that most will not opt to change, but they are there just in-case… W4S has set the default settings for optimal sonics.
The Roll-off slope setting configures the PCM filter as pictured below in the 20-20kHz frequency sweep. Fast Slow Volume Min / Max Settings More features that can be found in the setup menu are volume Min/Max settings that can be set differently for each type of input. The volume table for the DAC is 70 steps in size and offers different size steps depending on the location of the step.
Discrete Input Setting Input selection with the standard remote is accomplished by scrolling up or down through all available inputs. While our remote control does not have the option for direct input selection, many universal remotes can support that feature. The Discrete Input Setting (on/off) enables or disables the direct input commands that can be received by the DAC-2 DSD. The database for the Logitech universal remotes has these commands pre-loaded for your convenience.
One will find that the initial 100hours, the unit will start to shed the initial slight “brightness” and somewhat harsh transitions (as some will say). During the second 100 hours, your DAC will start to become more fluid, and smoother overall. Additional time is where the lesser of a change happens, and you will come to enjoy your new product for years to come. After the initial break in period, your unit will be ready to perform when powered on.
If the noise is easily heard at a distance, try putting your source on mute, or pause. If this eliminates the noise, it’s inherent in the source. If the noise is still there when the preamplifier is muted, try disconnecting the inputs to the amplifier. If the noise is still there when the inputs are disconnected, and the inputs are shorted with shorting plugs, then your amplifier may need some servicing.
