Operating Tips
Using the pm1400
Once the amplifier has been installed and wired into the system, you are ready to use it. Here are
some tips to help you get the most from it.
• Verify that the switches (Stereo / Mono, Clipping Eliminator and Level Defeat) have been set to the mode
that you want.
• When you power the system up for the first time (out of the carton), it’s a good idea to start with all of the
amplifier level controls turned down (counter clockwise), then advance them slowly, one at a time, so that
you can confirm that each amplifier channel is operating normally.
• Be sure that the Input Level controls are set sufficiently high to allow the preceding device to drive the
amplifier to full output. For most installations, this is wide open (fully clockwise).
• Once you have established settings, it is a good idea to mark them down, either on paper, or on pieces of
tape or sticky-dots attached to the amplifier’s panel.
• In bi-amplified (multi-amp) systems, it is a good idea to start with the low-frequency amplifiers turned off
or down, and to check each frequency range from highest to lowest to ensure that each loudspeaker
component is operating correctly.
Accessory Options
The amplifiers have internal connections for installing a variety of accessories to provide additional features
for specific applications. Some of the options available are:
• A precision attenuator which provides attenuation in 0.5dB increments down to -60dB. Settings are made
with a series of DIP switches on the module. (Order model AT2)
• A programmable two-way electronic crossover that outputs the high frequencies through one channel and
the low frequencies through the other channel. (Order model CX2)
• High quality balanced input transformers for applications that require electrical isolation.
(Order model XFK)
Contact your local Carver Professional Authorized Dealer for information on these and other accessory
modules that are available for the pm1400 amplifier.
