■ APR (Automatic Precision Reception) System
The APR system is Onkyo’s unique computer-controlled system
which automatically chooses the appropriate settings according to
the quality of the FM signal currently being received. This system
selects the appropriate Mode (STEREO or MONO), turns on the
Hi-blend function when the stereo broadcast contains noise in its
higher frequencies, and switches the IF band function to NAR-
ROW when the FM station signal is mixed with interference from
other stations.
● If the FM broadcast is received as a monaural signal, the STE-
REO indicator goes off.
● If the quality of the signal changes once the APR system has
adjusted the settings, the APR system will not automatically
readjust the settings. Change the settings by pressing the buttons
(IF BAND, HI-BLEND, MODE) on the main unit.
■ IF BAND button
When FM stations are mixed or there is interference, this button
corrects this as much as possible. Each press switches it as follows:
NORMAL/NARROW.
Normal mode (NORMAL) is selected for normal reception. Nar-
row mode (NARROW) is selected when other stations may be at
frequencies that are close to the desired station.
NOTE:
Depending on the radio station signal, it may be difficult to receive
RDS broadcasts when IF BAND is set to NARROW. If this is the
case, set IF BAND to NORMAL.
■ HI-BLEND button
Weak FM stations may exhibit noisy and hissy sound quality in
stereo mode. The high blend circuit blends only the highest fre-
quencies into mono, while the rest of the audio range remains in
stereo, with substantially reduced noise and hiss.
Each press switches between ON or OFF.
■ MODE button
If an AM station is being received, this button switches the mode
between auto-tuning and manual tuning.
If an FM station with a very weak and noisy signal is received,
improve the situation by switching to monaural, even if it is a ste-
reo broadcast. At this time, the MONO indicator will light up.
When it is noisy, turning ON HI-BLEND is also effective.
The three settings that can be selected with the MODE button can
be used to improve the reception of FM stations with weak signals.
Auto tuning setting (“AUTO” lights up.): Turn the PRESET/
TUNING dial to begin auto-tuning. The frequency changes in
steps of 50 kHz (or 200 kHz) when tuning an FM station or in
steps of 9 kHz (or 10 kHz) when tuning an AM station.
* The steps in which the frequency is changed differ according to the
country of purchase. The frequency steps shown in ( ) are for the
USA and Canadian model.
Manual fine setting (“FINE” lights up.): Turn the PRESET/
TUNING dial to manually tune in the station. The FM frequency
changes in steps of 25 kHz.
Manual fine monaural setting (“FINE” and “MONO” light up.):
This setting is like the previous one, except it plays the broadcast
in MONO so that even a station with a weak signal can be
received.
■ ANTENNA Button
If antennas have been connected to both the A and B FM antenna
connectors on the rear panel, select the one with better sensitivity
using the ANTENNA button on the remote control.
The antenna A/B selection status will be memorized at the Preset
Station Buttons.
■ FM Stereo Indicator (STEREO)
This indicator lights up when an FM stereo broadcast is being
received. It does not light when a weak FM stereo broadcast is
being received.
■ Signal Strength Indicator
Optimum tuning points are indicated by the number of lighted seg
ments.
Hold down the DISPLAY button to display “FM Signal” and the
signal strength in decibels (dB).
■ Displaying station information
During FM reception of any RDS station with PS, or when charac-
ters are being entered, the PS, or character information is dis-
played.
When you want to see the frequency, press the DISPLAY button.
Press it again to return to the original display.
If there is no PS or character display, the frequency will be dis-
played.
