The Dual-Stereo-Transistor Pre-amplifier TVV 46
enables a phono mechanism with Magnetic Cartridge
to be used with an Amplifier not containing an input
for a magnetic pickup.

The Dual TVV 46 amplifies the output of the

magnetic cartridge and deliversacorrectly equalized
output signal.

This unit meets or exceeds all the requirements of
DIN 45 500 for Home-Studio equipment [Hi-Fi).

1. Power supply

Before connecting to power line, check line voltage.
The TVV 46 is normally shipped connected for
220 V. To change the line voltage, remove the

protective cover and unsolder the connecting cable
(Fig. i).

Caution - disconnect from power line before
opening unit.

a) Connection to Dual High Fidelity Record Player
with 5-contact power line plug (Fig. 2)

For the direct connection of the TVV 46. use the

connection points provided on the line switch of
the record player marked: >.

Disconnect the power line plug from the line switch

and insert the adapter plugs of the power connection
cable into the boreholes of the plug until they look.

Then connect the power line plug again with the
line switch of the record player.

b) Connectlon to Dual High Fidelity Record Player
with clamp connector (Fig. 3)

if the TVV 46 is to be connected to a high fidelity
record player equipped with a clamp connector
terminal, separate the adapter plugs of the power
line cable at the point Indicated (Fig. 2).

Separate the power line plug of the record player
from the power line, and push the cable of the
TVV 46 into the clamp connector, then tighten
it with a screw driver.

c) Connection to the Dual High Fidelity Record
Player using solder connections

Some special production runs of Dual Hi-Fi units
do not have a clamp connector. Connect the power
line cable of the TVV 46 to clamp connectors 5
and 6 of the power switch in units without voltage
selector. or to connectors 7 and 8, if the unit has
a voltage selector. (See schematic in the record
player operating manual.)

d) Connection to phono units In general

When the TVV 46 is used with another phono
mechanism, it is recommended that power be
supplied via the line switch on the record player or
on the main amplifier so that all will be turned on
or off together.

If need be, the TVV 46 can also be plugged in
directly into a power receptacle.
