built-in installation less proper ventilation is provided.
(8) These products should be operated from the type of power source indicated on the
marketing label. If you are not sure of the type of power available, consult your dealer or
local power company.
(9) This product is equipped with a 3-wire grounding type plug, a plug having a third (grounding)
pin. This plug will only fit into a grounding-type power outlet. This is a safety feature, if you
are unable to insert the plug into the outlet, contact your electrician to replace your obsolete
outlet. Do not defeat the purpose of the grounding-type plug.
(10) Do not allow anything to rest on the power cord. Do not locate this product where persons
will walk on the cord.
(11) If an extension cord is used with this product, make sure that the total of the ampere
ratings on the product plugged into the extension cord to the waplugged into outlet does not
exceed 15 ampere.
(12) Never push objects of any kind into this product through cabinet slots as they may touch
dangerous voltage points or short out parts that could result in a risk of fire or electric shock.
Never spill liquid of any kind on the product.
(13) Do not attempt to service this product yourself, as opening or removing covers may
expose you to dangerous voltage points or other risks. Refer all servicing to service
personnel.
(14) Unplug this product from the wall outlet and refer servicing to qualified service personnel
under the following conditions:
a. When the power cord or plug is damaged or frayed.
b. If liquid has been spilled into the product.

Stereo D/A Converter CS4334
DESCRIPTION
The CS4334 family members are complete, stereo digital to analog out put systems including
interpolation, 1-bit D/A conversion and out put analog filtering in an 8-pin package. The CS4334
support all major audio data interface formats, and the individual devices differ only in the supported
interface format.
The CS4334 family is based on delta-sigma modulation, where the modulator output controls the
reference voltage input to an ultra-linear analog low-pass filter. This architecture allows for infinite
adjustment of sample rate between 2kHz and 100kHz simply by changing the master clock frequency.
FEATURES
*Complete stereo DAC system: Interpolation D/A, Output analog filtering.
*24bit Conversion.
*96dB dynamic range.
*-88dB THD+N
*Low clock jitter sensitivity.
*Filtered line level outputs
*On-Chip digital de-emphasis
*Popgaurd technology.
