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

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.
