32. TAPE-2 Monitor Terminal
This terminal offers the same function as the TAPE-1 Moni¬
tor Terminal. For playback through this terminal press in both
the Tape Monitor and Tape Selector Switches.
33.
Phono Terminal
This input terminal functions in two ways according to the
position of the Input Selector Switch. When the selector switch
is in the "phono MM" position, you can connect the output
of an MM-type cartridge. In this case the input sensitivity of this
terminal is 2.2mV with impedance 45k ohms. While in the
"phono MC" position, the phono equalizer stage is changed to
produce higher gain, thus making it possible to connect a
moving coil type cartridge to this terminal. In.this case, the
input impedance is 220 ohms with sensitivity 300/zV.
34.
Aux Terminal
This is an auxiliary input terminal for playback of such
program source of flat frequency response as SW/LW tuner, line
output of tape recorder, and audio output of TV receiver.
Input sensitivity is 165 mV and input impedance 50 k ohms.
35.
Ground Terminal
Connect the earth lead-wire of record player (from tonearm
or motor). This terminal may be used as an earthing terminal of
this tuner-amplifier, which is, however, not always necessary.
36.
Extra AC Outlet (UNSWITCHED)
This outlet is convenient for supply of AC power to other
annexed audio components such as record player, tape recorder
etc. This terminal is independent of the Power Switch (17) of
this tuner-amplifier where the AC power is always available.
The maximum capacity of the terminal is 200W.
Installation
■HBanBHBBManBnnaBaHi
While the R-3045 Tuner-Amplifier has been designed for
maximum ease of installation and operation, we strongly suggest
you read this section through before proceeding to connect and
operate the unit Because the R-3045 incorporates many techni¬
cal and operating refinements, it may be a bit different from
equiprrent you have used in the past.
Placement and Mounting
The R-3045 may be placed in virtually any convenient loca¬
tion, keeping in mind the necessity of connecting cables to your
speakers and an antenna for FM.
Because of its advanced
solid-state construction, the unit produces little heat.
But
certain minimum ventilation requirements are still necessary to
provide optimum operation.
When the R-3045 is placed on an open shelf in a bookcase or
cabinet (mounted in its integral metal case or with the accessory
furniture case) about 10 cm (3") of free space should be allow¬
ed above it.
CAUTION:
The R-3045 employs most up-to-date heatloop type
heat sink for more effective heat dissipation at the
final output stage, and caution should be paid to its
placement.
Place the R-3045 always in horizontal, as
otherwise
heat dissipation becomes
insufficient to
damage the power transistors.
Antennas
Except in fringe areas no additional AM antenna is required
with the R-3045.
For FM, a folded dipole, available from your
dealer, is generally adequate. This section will tell you how to
connect them.
