Sphere Of Application - Palmer PLB2X8 Manual De Usuario

SphERE Of AppLIcATION

Unlike transistor amplifiers, amplifiers with a tube power stage always
require a speaker on the corresponding output. Ideally, the impedance
(ohm rating) of the speaker enclosure and the amplifier output should be
equal. Operating an amplifier without any load at all can result in de-
struction of the amplifier.
The Palmer PLB2X8 load box can be connected safely to a tube amplifier
instead of a speaker in situations where direct sound in the room is not
desired. For example, this is frequently the case in home studios where
minimizing noise is an issue.
The box contains two separate loads, each with an impedance of 8 ohms.
Thus the PLB2X8 is ideal for supplementing the Palmer PDI05 and PGA05,
which do not have a built-in load box.
In addition to 2-channel (stereo) operation, the PLB2X8 can also be used
in one-channel mode. Alternatively, impedances of 4 and 16 ohms are also
available. The load rating doubles.
