Glossary - T+A Elektroakustik T 1210 R Betriebsanleitung

Attenuator
When stations are received close to an unusually
powerful local transmitter,
(whistling and twittering noises) may occur. The
attenuator damps the signal received by the antenna,
and thereby reduces the unwanted effects.
Cable Network
When the T 1210 R's tuner was being developed the
requirements of the European cable network were given
high priority. The tuner copes very well with excessive
signal levels, and its high selectivity avoids many of the
problems involved with cable operation, without any
reduction in reproduction quality.
dB
The unit of measurement for electrical levels is the deci
Bel (dB).
Field strength
The electrical field strength is a measurement of the level
(strength) of the radio signal supplied by the antenna. In
general terms, the higher the field strength of the tuned
station, the better the reception quality.
1. Distance from radio transmitter
2. Obstacles (mountains etc.) between transmitter and
receiver
3. Transmitter output power
4. Quality and direction of the tuner antenna system.
Point 4 is of crucial importance here. It is impossible to
obtain good reception with a poor aerial system.
Your specialist  dealer will be glad to advise you on
the subject of installing or improving your aerial system,
taking your specific local reception conditions into
account.
FM = Frequency Modulation
All VHF radio transmitters use the 'FM' method of
modulation. This technology provides maximum possible
sound quality and interference suppression.
Muting = Hiss suppression
The T 1210 R features automatic hiss suppression which
cuts out the annoying hissing sound between radio sta-
tions, and suppresses very weak stations which cannot
be received with reasonable quality.

intermodulation effects
NARROW = narrow band
IF filter circuit with a narrow pass band (see also 'WIDE').
Preset = station memory
The T 1210 R can store all the settings for 60 stations,
any of which can be recalled simply by pressing a button.
RDS = Radio Data System
Many radio stations broadcast supp-
lementary digital information simul-
taneously with the programme. The
T 1210 R is equipped with an RDS
decoder, and displays the station
name of RDS transmitters in plain text on its alpha-nume-
ric screen. This is a great advantage when searching for
particular stations.
Seek threshold
The seek threshold is the minimum field strength value at
which the automatic station search process halts. It is set
at a level which ignores very weak transmitters.
Standby
The T 1210 R can be switched on from the Standby state
from the remote control handset.
Tuning indicator = tuning centre meter
The centre indicator in the display informs you when a
station is perfectly tuned in.
When the cross symbol is in the centre position, the
station is correctly tuned and can be received at the best
possible quality.
If the cross is in the left-hand or right-hand position, you
can correct the tuning manually.
WIDE = wide-band
In the Intermediate Frequency (IF) stage the signal from
the tuned-in station is filtered out of the received signal.
With the T 1210 R you can choose between a wide-band
filter and a narrow-band filter, with a sharp cut-off.
The wide-band setting
reproduction quality, provided that reception conditions
are very good and that no other transmitters frequency is
located close to the tuned-in station.
