PTRL NV/3 & RXRL NV/3
Like the previous screen, this screen shows current peak level in the left and right
channel signals in the form of two analogue sliding bars. A vertical line indicates 0dB
position; unstable readings associated with repetitive test signals are possible in
this menu as well.
9.5.9 Screen #06: RDS or SCA auxiliary signal level and modulation
This screen shows current modulation as determined by the auxiliary signal (RDS,
SCA) alone in kHz and peak level expressed in dB for 7.5kHz deviation, i.e. 10% of
maximum modulation. Standard modulation of RDS level is 2kHz, i.e. -11.5dB.
Modulation for an SCA signal is usually higher, typically 7.5kHz, i.e. 0dB.
9.5.10 Screen #07: RH, LH auxiliary signal levels and total modulation in
dB
This screen provides an overview of modulation level in dB for the auxiliary (AUX),
left (L), right (R) and total or multiplex (MPX) signals, as shown in the previous screens.
9.5.11 Menu #09: Internal temperature
This screen shows internal temperature in degrees Celsius. The ambient temperature
sensor detects internal temperature right behind the front panel: at full output power
and rpm, its reading will be several degrees higher than room temperature.
At regular operating speed, external (room) temperature may be up to 6 - 8 °C higher
than internal temperature. Maximum operating temperature allowed (45°C)
corresponds to a 51 - 53°C readout on the screen.
At full power, outer cooler temperature is normally 10-15°C higher than ambient
temperature.
