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).

There are several settings in the setup menu that most will not opt to change, but are there just in-
case… W4S has set the default settings for optimal sonics. Certain systems may benefit from changing these
settings, and is really a personal preference more than anything. PCM Bandwidth selects the range of which
the dac will filter the signal. Allowing higher bandwidths may introduce more information and noise than
desired. IIR stands for Infinite Impulse Response. This is another setting that each customer should tune to
their liking. Please note that these settings offer the slightest sonic differences and may not be really noticed
or appreciated until the unit is fully “broken-in”.

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. When a system doesn’t have enough gain to utilize the bottom
several steps, you can remove them from the table by setting the volume minimum setting to with-in the
playback range of the system. Because of the high output level of the DAC, it may offer the possibility of
higher levels than needed. To prevent the possibility of amplifier overdrive, or possible speaker damage, we
recommend setting the volume Max level with-in your personal preferences. The features listed above are
some of the ways the DAC can adapt to everyone’s system for optimal integration without the worry of having
too much or too little gain.
Example:
When the minimum level for the corresponding input is set to 5, the maximum level will be 65. Basically the
min level is the amount of steps skipped in the first position. When used, the min level is subtracted from the
70 possible steps total. With an inefficient system requiring a volume level of 12 to hear anything, a min level
of 10 removes steps 1-10 and max equals 60. The volume table offers from 3db to 1dB steps as follows: 0 =
mute; steps 1-9 = 3dB; steps 10-24 = 2dB; steps 25-70 = 1dB

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
