CONNECTING THE T50
Power supply requirements
To operate the tuner it is necessary to first connect the unit to the mains supply via the
power cord supplied. There is an IEC mains connector on the rear panel that contains a
protection fuse and mains switch. The power must be turned On (1) or Off (0) from here.
After switching On the tuner will be in Standby and pressing the STANDBY button on the
front panel will wake it up.
The power cord should be connected to the tuner and to a domestic mains socket
carrying 220-240V AC 50Hz or 110-120V AC 60Hz, depending on country of use.
Should it be necessary to replace the fuse, ensure that you use the same type as
specified on the rear panel.
ie: 5 x 20mm cartridge type
T 500 mA surge resisting for 220-240V 50Hz AC,
T 1 A surge resisting for 110-120V 60Hz AC
T 1A surge resisting for 100V (Japan).
Antenna requirements
To obtain the best quality FM signal, in stereo with low background noise, it is
necessary to use a good antenna (aerial), preferably mounted on a roof of a building, or
in an attic or loft. A 75 ohm co-axial cable should be used to bring the radio signal to
the tuner. Use a good quality 75 ohm co-ax plug to connect the radio signal into the rear
panel socket marked: FM antenna 75 ohms. In some parts of the world 300 ohm
balanced feeder cable is more popular, in which case it should be connected to the 300
ohm terminals only.
If it is not possible to use an outdoor aerial, a balanced 300 ohm indoor T-antenna will
give reasonable results when connected to the 300 ohm terminals. Note that the
direction of the T-piece with respect to the transmitter site will affect the strength and
quality of reception, giving more or less noise, especially on stereo signals.
The AM part of the radio will work very well using a single wire. Pug the 3 metre length
of thin stranded wire provided into the terminal marked AM on the back panel. Adjust
its position with respect to the direction of the transmitter to improve reception.
Output from the tuner
To connect the audio signal from the tuner to an amplifier it is necessary to use a pair
of cables terminated with (RCA) phono plugs. Shielded types of interconnect are
better for reducing hum or other interference pick-up, but unshielded typed like DNM will
produce a better sonic performance.
Don’t sacrifice quality for price in this important area.
