Audio input
connections
There are two types of input signals that
your TC Series amplifier may receive: low-
level (preamp-level) output or high-level
(speaker-level) output.
Low-level (preamp-level)
connections
Connect the left and right preamp output
cables from your head unit, electronic
crossover, low-level equalizer (commonly
referred to as a passive equalizer), or
preamplifier to the left and right INPUT
RCA
connectors on your TC Series ampli-
fier. (See the "Controls and operations"
section for information about adjusting
input level.)
You may want to use high-quality preamp
cables (although noise at this point should
not
be
a factor because the differential
INPUT connectors on the TC Series ampli-
fiers are capable of rejecting radiated noise
induced in cables). If you decide to use
higher-quality preamp cables. use the type
with a shielded, twisted pair of signal wires,
if possible. The separate shield should not
be grounded at the amplifier end.
