Magnetic elds
The device generates strong magnetic elds that can interfere with the function
of poorly shielded devices. The strongest magnetic elds are directly above and
below the power amplier. Therefore, never place sensitive devices such as pre-
ampliers, radio transmission systems, or tape decks directly above or below the
power amplier. When installing the power amplier into a rack, you should place
it in the lowest position, and further equipment such as pre-ampliers in the
highest position.
The following section explains the possible operating modes of the device. Channels 1 and 3
are marked there with ‘A’ and channels 2 and 4 are marked with ‘B’.
