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 Crown Pro Information Guide 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, turn the amplifier level down and the AC power off to
minimize the chance of short-circuiting the output.

Typical Input
Wiring
If the Mode switch is in “Bridge-Mono” position, only
the Channel 1 input connectors should be used.
2.5—Connect the outputs of the CE-Series amp to your loud-
speakers. For Stereo mode, refer to the Stereo Output
Hookup diagram (Figure 2.4). For Bridge-Mono mode, re-
fer to the Bridge-Mono Output Hookup diagram (Figure
2.5).
WARNING: Output terminals marked with the
symbol
are dangerous when live. External wiring connected to
these terminals requires installation by an instructed per-
son, or should make use of prebuilt wiring and connec-
tors.

Output Wiring Tips
1. Although this amp has Speakon connectors to minimize wiring mis-
takes, we encourage you to choose carefully when selecting
speaker enclosure connectors.
2. To prevent possible short circuits, wrap or otherwise insulate ex-
posed loudspeaker cable connectors.
3. Do not use connectors that might accidentally tie conductors to-
gether when making or breaking the connection (for example, a standard,
1
/4-inch
(6.35-mm) stereo phone plug).
4. Never use connectors that could be plugged into AC power sockets. Accidental AC
input will be an electrifying experience for your equipment. But you will find out real
quick if your speakers are any good at 60 Hz.
5. Avoid using connectors with low current-carrying capacity, such as XLRs.
6. Do not use connectors that have any tendency to short.
7. To maintain good bass response, use the lowest DC resistance cable you can af-
ford and will terminate safely in your connectors.
