2.7.2 Bridge-Mono Mode
Typical input and output wiring is shown in
Figure 2.10.
NOTE: Crown provides a reference of wiring pin assignments for
commonly used connector types in the Crown Amplifier Application
Guide available at www.crownaud i o.com.
OUTPUTS Cconnect the speaker across barrier-strip terminals 1 + and 2+.
IMPORTANT : Set the Bridge/Normal switch in the LCD
screen to " Bridge. " See Section 4. 1.5.
NOTE: In Bridge-Mono mode , only the
Channel 1 Level control is functional (unless you make an
alternate selection via the "Y" menu. See Sect i on 4.1.5) .
2.8 Connect to AC Mains
Connect your amplifier to the AC mains power source (power
outlet) with the supplied AC power cordset. First, connect the IEC
end of the cordset to the IEC connector on the amplifier; then, plug
the other end of the cordset to the AC mains.
WARNING : The t hird prong of this connector (ground) is
an important safety feature . Do not attempt to disable
this gro u nd connection by using an adapter or other
methods .
Amplifiers don't create energy . The AC mains voltage and current
must be sufficient to deliver the power you expect. You must
operate your amplifier from an AC mains power source with not
more than a 10% variation above or a 15% variation below the
amplifier's specified line voltage and within the specfied frequency
requirements (indicated on the amplifier's back panel label). If you
are unsure of the output voltage of your AC mains, please consult
your electrician.

2.9 Protecting Your Speakers
It's wise to avoid clipping the amplifier signal. Not only does
clipping sound bad, it can damage high-frequency drivers. The
built-in clip limiter prevents clipping.
Also, avoid sending strong subsonic signals to the amplifier.
High-level, low-frequency signals from breath pops or dropped
microphones can blow out drivers. To prevent subsonic signals,
use System Architect software to insert a high pass filter (see
Section 4.1.6). Alternatively, switch in high pass filters at your
mixer. Set the filter to as high a frequency as possible that does not
affect your program. For example, try 35 Hz for music and 75 Hz for
speech . On each mixer input channel, set the filter frequency just
below the lowest fundamental frequency of that channel's
instrument.

2.10 Startup Procedure
Use the following procedure when first turning on your amplifier:
1. Turn down the level of your audio source.
2. Turn down the level controls of the amplifier.
3. Turn on the "Power" switch. The Power indicator should glow.
4. Turn up the level of your audio source to an optimum level.
5. Turn up the Level controls on the amplifier until the desired
loudness or power level is achieved. NOTE: In Bridge-Mono
mode, only the Channel 1 Level control is functional (unless you
make an alternate setting with the Y processing block). When
Bridge Preset is used, both Level controls are functional.
6. Turn down the level of your audio source to its normal range.
If you ever need to make any wiring or installation changes, don't
forget to disconnect the power cord.
For help with determining your system's optimum gain structure
(signal levels) please refer to the Crown Amplifier Application
