· TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor devices in general
can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the
buyer, when utilizing TOSHIBA products, to comply with the standards of safety in making a safe design for the entire system, and
to avoid situations in which a malfunction or failure of such TOSHIBA products could cause loss of human life, bodily injury or
damage to property.
In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as set forth in the
most recent TOSHIBA products specifications. Also, please keep in mind the precautions and conditions set forth in the “Handling
Guide for Semiconductor Devices,” or “TOSHIBA Semiconductor Reliability Handbook” etc..
· The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal
equipment, office equipment, measuring equipment, industrial robotics, domestic appliances, etc.). These TOSHIBA products are
neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunction or
failure of which may cause loss of human life or bodily injury (“Unintended Usage”). Unintended Usage include atomic energy
control instruments, airplane or spaceship instruments, transportation instruments, traffic signal instruments, combustion control
instruments, medical instruments, all types of safety devices, etc.. Unintended Usage of TOSHIBA products listed in this document
shall be made at the customer’s own risk.

l Woofer LPF fo (Sub address 07 (h) / b5~b4)
These bits set cut off frequency (fo) of the low pass filter for W-ch.
Set the bits to 00 (b), fo is 100 Hz (−3 dB point). Set the bits to 01 (b), fo is 125 Hz. Set the bits to 10 (b), fo is
170 Hz. Set the bits to 11 (b), fo is 210 Hz.
Switch on default data is 01 (h).
l Woofer LPF defeat (Sub address 07 (h) / b3)
Set the bit to 1 (b), Woofer LPF is defeated.
This function is for IC testing. so, this bit must be set to 0 (b).
Switch on default data is 0 (b).
l Bass boost switch (Sub address 07 (h) / b7)
Bass boost function is adding W-ch signal to main channel signals. It can boost low frequency signal without
woofer output.
Set the bit to 0 (b), Bass boost is inactive. Set the bit to 1 (b), bass boost is active.
Switch on default data is 0 (b).
