CE-Series Amps with an Attitude!

—
Connect the inputs
of the CE-Series amp to your mixer,
equalizers, or signal processors ahead of the amp. Three
types of balanced input connectors are provided, allow-
ing you to choose barrier strip,
1 /
4
-inch phone or 3-pin
XLR connectors. You can also choose to use either bal-
anced or unbalanced wiring. (See the information on
“Balancing the Line” in the
Other Issues section for an
explanation of balanced vs. unbalanced wiring.)
If the Mode switch is in “Bridge-Mono” position, only the
Channel 1 input connectors should be used.

Input Wiring Tips
1. For all input connectivity, use shielded wire only. Cables with a foil
wrap shield or a high-density braid are superior. Cables with a
stranded spiral shield, although very flexible, will break down over
time and cause noise problems.
2. Try to avoid using unbalanced lines with professional equipment. If
you have no choice, keep the cables as short as possible. (Refer to
the information on “Balancing the Line” in the Other Issues section.)
3. To minimize hum and crosstalk, avoid running low-level input, high-level output and AC
power feeds in the same path. Try to run differing signal paths at 90° to one another. If you
must use a common path for all cables, use a star-quad cable for the low-level signals.
4. When changing input connectors or wiring, turn the amplifier level controls all the way
down (counter-clockwise) before connecting or disconnecting input plugs.
5. When changing output connections, a professional dude will turn the amplifier level down
and the AC power off to minimize the chance of short-circuiting the output.
