Volume Control; Pre-Amplifier - T+A R 1260 R Betriebsanleitung

NARROW = narrow band
IF filter circuit with a narrow pass band (see also
"WIDE").
PRESET = station memory
The receiver 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
receiver is equipped with an RDS
decoder, and displays the station
name of RDS transmitters in plain text
on its alpha-numeric screen. This is a
great advantage when searching for particular stations.
Search threshold
The search threshold is the minimum field strength value
at which the automatic station search stops. It is set at a
level which automatically skips very weak stations.
Source unit
SOURCE devices are all the elements of a Hi-Fi system
which supply a sound signal, such as tuners, CD-players,
tape recorders. We also have to differentiate between
auditioning sources and recording sources:
An auditioning source is the unit which you are listening
to at any time. This unit can be remote-controlled.
A recording source is a source device, whose output
can be recorded by a recorder via recording output
TAPE. Recording sources cannot be remote-controlled.
STANDBY = 'ready' mode
The receiver can be switched on from the Standby state
from the remote control handset.
TASI
This standardised  interface makes it possible to
loop-in a  surround decoder between the source
select switch and the volume control of the receiver.
The interface automatically detects a decoder which is
connected in this way, and automatically switches to
surround mode. In surround mode the volume and tone
controls of the receiver are disabled, as these functions
are now assumed by the decoder.
Tuning indicator = centre tuning indicator
The centre indicator on the screen allows you to judge
when a station is correctly tuned. When the cross symbol
is in the centre, the station is correctly tuned, and recep-
tion will be as good as is possible. If the cross is left or
right of centre, the tuning can be corrected manually.

Volume control

The receiver is fitted with a two-stage volume control
which allows the input stage of the pre-amplifier to work
at a high level of amplification without overloading the

pre-amplifier.

This is the task of the first volume control. As a result the
signal is at a higher level at the subsequent processing
stages, which substantially reduces background hiss and
distortion where the signal approaches the zero level.
The second volume control, located directly before the
output stage, reduces low-level hiss produced in the pre-
amplifier.
WIDE = wide-band reception
In what is known as the Intermediate Frequency (IF)
stage the signal from the currently selected station is
filtered out of the received signal. With the R 1260 R it is
possible to select either a wide filter 'window' (= broad-
band) or a narrow 'window' (= narrow-band). In the wide-
band setting the reproduction quality is slightly better,
provided that reception conditions are very good, and
that there are no transmitters close to the selected station
which could cause interference.
