Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called
Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and
The following techniques should be used to help reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on
your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,
which should be removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges
5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement
ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the
CAUTION : Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together
or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.
Components identified with the IEC symbol in the parts list are special significance to safety. When replacing a component identified with
, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the
parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably
insulated from the supply circuit before retuming the product to the customer.

On early versions of the AVR130,AVR230,AVR330,HK3380,HK3480, when the volume control is turned, the
volume level and display may be erratic, and not track accurately, or the level may progress in an unintended
direction. This may happen on a random basis and depends on where the volume control knob is positioned
after a volume adjustment. During a running production change, new volume encoders were installed.
In the event you receive an AVR model listed above with the complaint “The volume control on my
receiver does not track accurately when turned”, perform the following procedure:
Note: It is important that the various screws do not get mixed up and inserted in other locations upon reassembly. Make

GENERAL DESCRIPTION
The AK4358 is eight channels 24bit DAC corresponding to digital audio system. Using AKM's advanced
multi bit architecture for its modulator the AK4358 delivers a wide dynamic range while preserving
linearity for improved THD+N performance. The AK4358 has full differential SCF outputs, removing the
need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The
AK4358 accepts 192kHz PCM data and 1-Bit DSD data, ideal for a wide range of applications including
DVD-Audio and SACD.
FEATURES
o Sampling Rate Ranging from 8kHz to 192kHz
o 24Bit 8 times Digital Filter with Slow roll-off option
o THD+N: -94dB
o DR, S/N: 114dB
o High Tolerance to Clock Jitter
o Low Distortion Differential Output
o DSD Data input available
o Channel Independent Digital De-emphasis for 32, 44.1 & 48kHz sampling
o Zero Detect function
o Channel Independent Digital Attenuator with soft-transition (3 Speed mode)
o Soft Mute
o 3-wire Serial and I2C Bus µP I/F for mode setting
o I/F format: MSB justified, LSB justified (16bit, 20bit, 24bit), I2S, TDM or DSD
o Master clock: 256fs, 384fs, 512fs or 768fs (PCM Normal Speed Mode)
128fs, 192fs, 256fs or 384fs (PCM Double Speed Mode)
128fs or 192fs (PCM Quad Speed Mode)
512fs or 768fs (DSD Mode)
o Power Supply: 4.75 to 5.25V
o 48pin LQFP Package

24Bit 96kHz ∆Σ ADC
GENERAL DESCRIPTION
The AK5381 is a stereo A/D Converter with wide sampling rate of 4kHz ∼ 96kHz and is suitable for
High-end audio system. The AK5381 achieves high accuracy and low cost by using Enhanced dual bit
∆Σ techniques. The AK5381 requires no external components because the analog inputs are single-
ended. The audio interface has two formats (MSB justified, I2S) and can correspond to many systems like
music instrument and AV receiver.
