RDS / RBDS Radio (Broadcasting) Data Service — a narrowband digital subcarrier centered at 57 kHz in
the FM baseband that usually provides program or network-related data to the consumer in
the form of text that is displayed on the radio. Occupied bandwidth is ±2500 Hz.
REF reference
RF radio frequency
RFI radio-frequency interference
RMS root-mean-square
ROM read-only memory
SC subcarrier
SCA subsidiary communications authorization  a non program-related subcarrier in the FM
baseband above 23 kHz (monophonic) or 57 kHz (stereophonic)
S/PDIF Sony / Philips digital interface (standardized as IEC958)
TRS tip-ring-sleeve (2-circuit phone jack)
THD total harmonic distortion
TX transmitter
s Microseconds. For FM pre-emphasis, the +3 dB frequency is 1 / (2  ), where  is the pre-
emphasis time constant, measured in seconds.
VCA voltage-controlled amplifier
VU volume unit (meter)
XLR a common style of 3-conductor audio connector
XTAL crystal
Many parts used in the 8300 are surface-mount devices ("SMT") and are not in-
tended for field replacement because specialized equipment and skills are necessary
to remove and replace them. The list below includes substantially all of the parts
used in the 8300 (including surface-mount devices), and inclusion of a part in this list
does not imply that the part is field-replaceable.
See the following assembly drawings for locations of components.
