1) ThE GROUND-LIFT SwITCh
Next to the sockets for the power amplifier inputs, on the front panel, a
pressure switch labelled
down position, this switch disconnects the ground connection to the amp-
lifier. As mentioned above, it can be used to prevent ground loops due to
dual earthing. Since ground loops always depend on local conditions, it
can be difficult to determine in advance which of the pressure switches
are best to press. The switch positions that provide the least hum are
the right ones. Here, it is a case of trial and error, since there is no
danger of fatal damage.
At Palmer, we tested the TINO SYSTEM under various conditions and were
always able to achieve a noise free result, unless an amplifier or other
device in the chain generated hum internally. It is highly recommended
to power the amplifiers and their associated devices from a power strip/
distribution.
TINO SYSTEM CONNECTED AS SwITChER A / B BOx
The device can also be used as an A / B box. For example, if you use two
combo amplifiers with built-in speakers or amp heads with their own box,
using the sockets
fiers with signal, while the speaker sockets remain unoccupied.
THE FOLLOWING WIRING SHOULD BE APPLIED WITH DISABLED AMPLIFIERS.
