CAUTION
! Do not locate sensitive high gain equipment such as preamplifiers or tape decks directly above
or below the unit. This unit has a strong magnetic field which can induce hum into unshielded devices that
are located nearby. The field has strongest spots just above and below the unit. Locate the amplifier at the
bottom of the rack and the preamplifier or other sensitive equipment at the top.

amplifier.
The dB control range is as follows: Fully closed (the signal is at zero and not sent to the channels of
the amplifier) or fully open (i.e. at rated power: the signal is not attenuated at all and sent at the input
power into the amplifier channels)
