The T 758’s internal AM/FM tuner offers very high quality sound from radio
broadcasts. The reception and sound quality will always be dependent to a
degree however on the type of antenna(s) used as well as proximity to the
broadcast origin, geography and weather conditions.
ABOUT ANTENNAS
The supplied FM antenna can be connected to the rear panel FM antenna
input using the included “balun” adapter and should be fully extended
to form a “T”. This folded-dipole antenna will usually work best when
oriented vertically, with the arms of its “T” fully outstretched and arranged
perpendicular to the origin of the desired broadcast. There are no
“rules” however, and experimenting freely with antenna placement and
orientation may yield the clearest sound and lowest background noise.
In areas of poor FM reception, an exterior FM antenna can improve
performance dramatically. If radio listening is important to you, consider
consulting an antenna installation professional to optimize your system.
The supplied AM “loop” antenna will usually provide adequate reception.
However, an exterior AM antenna can be used to improve reception.
Consult an antenna professional for more information.
IMPORTANT NOTE
When using the AVR 4 to carry out AM/FM commands, ensure that the
DEVICE SELECTOR is set to “TUN”.
ASSEMBLING THE LOOP ANTENNA
1
Rotate the outer frame of the antenna.
2
Insert the bottom edge of the outer frame into the groove on the stand.
3
Extend the antenna cord.
SELECTING A TUNER BAND
Press the [AM/FM/DB] button on the AVR 4 while at AMP or TUNER device
selector page. Each subsequent press will toggle you through AM, FM or
DAB band.
Stop (release button) at your desired tuner band.
TUNING AM/FM STATIONS
Upon selecting AM or FM band, use SCAN [
5/6
] on the AVR 4 to perform
slow manual search; press and hold to automatically search.
The front panel [
a/s
] or AVR 4’s [
A/S
] buttons can also be used to tune
for stations.
1
Press [
A/S
] momentarily to step up or down between AM or FM
frequencies.
2
Press and hold [
A/S
] for more than 2 seconds to search up or down - the
T 758’s tuner will stop at the next sufficiently strong signal it encounters.
3
Pressing the [
A/S
] during the search process will stop the search.
DIRECT TUNING
If you know your desired station’s frequency allocation, you can tune
directly to the station.
1
Toggle [ENTER] button to switch between “Preset” and “Tune” mode (see
the lower line of the VFD). Select “Tune” mode.
2
Using the numeric keys of the remote control, key-in the frequency
allocation of the station. For example, to enter 104.50MHz, press “1”, “0”,
“4”, “5” and “0”.
STORING PRESETS (AM/FM/DAB)
The T 758 can store a mix of your 40 favorite AM, FM and DAB radio stations
for immediate recall.
1
To store a desired AM/FM station to a preset, first tune to the desired
frequency (see above), then press AVR 4’s [MEMORY] button. The VFD
will show the next available Preset number - for example, “Preset 4 Free”
in the lower line.
2
Press the [MEMORY] button again to store the desired frequency on
the Preset number shown (“P04” is shown in the upper right corner of
the VFD). Your desired frequency is now stored in the assigned preset
number.
NOTE
If there is no more vacant Preset number, you can overwrite an existing
Preset number by pressing the [
D/F
] buttons to select the Preset
number you want to overwrite.
DIRECT RECALL OF A PRESET NUMBER (AM/FM/DAB)
You can directly recall a desired Preset number.
1
Toggle [ENTER] button to switch between “Preset” and “Tune” mode (see
the lower line of the VFD). Select “Preset” mode.
2
Using the numeric keys of the remote control, directly key-in your
desired Preset number. For example, to enter Preset 5, press “5”.
DELETING A STORED PRESET (AM/FM/DAB)
You can empty a preset by deleting the stored information.
1
Select the preset number to be deleted. For example, “P03”.
2
Press and hold [DELETE] button until the current Preset number shown
in the VFD is extinguished (“P03” becomes “P--”.).
CHOOSING THE TUNER MODE
The AVR 4’s [TUNER MODE] key is a dual-purpose control. Toggle [TUNER
MODE] to switch between “FM Mute On” and “FM Mute Off”. In the normal
position, “FM Mute On”, only the stations with a strong signal can be
listened to, and the noise between stations is muted.
Pressing the [TUNER MODE] button again (“FM Mute Off”) allows distant
and potentially noisy stations to be received. Noise is reduced if the FM
station signal level is less than the FM Stereo threshold (since mono FM is
inherently less noise-prone) though at the sacrifice of the stereo effect.
NOTE
One can store the same channel in two preset locations - one with “FM
Mute On” and another with “FM Mute Off”.
