DPC

1400X

Thank you for purchasing the DPC

1400X! The DPC

1400X represents years of digital power

amplifier research packed into a one rack space power-house. Delivering 1,400 watts into
4 ohms bridged, or 2 x 700 watts into 2 ohms in stereo, the DPC 1400X reaches new output
heights.

With all connections on the back panel and all the controls on the front panel, the DPC 1400X
is certain to make life a lot easier for the installers and in live performance applications. You’ll
also find Peavey’s patented DDT

™

compression circuitry and combo connector inputs two really

convenient and useful extras.

Please read all of this before using the DPC 1400X as it contains important precautions and safety
information.

FRONT PANEL FEATURES

STATUS LEDs (1)
Bi-colored LED used to indicate the status of the channel. Channels A and B have separate Status
LEDs to monitor channel conditions. If both LEDs are not lit at power-up, follow the procedure to
check if the fuse needs replacing. If only one channel’s Status LED is lit check to see it the amp
is in bridge mode (4). If the LED is green, this indicates a normal operation. If the LED is red, then
the amplifier is overheated and will shut down for approximately 5 minutes or until cool enough to
operate safely. If the LED pulsates red, this indicates that there is a problem with the amplifier and it
should be serviced by a qualified technician.

INPUT SENSITIVITY (2)
These controls are used to adjust the input gain of each channel. Maximum gain is achieved with
the control turned fully clockwise. In this position the user will achieve maximum system headroom.
If set lower than full clockwise, lower system noise will occur at the expense of headroom.

SIGNAL LED (3)
Bi-colored LED used to indicate the signal status of a channel. If the LED is not lit, this indicates
no signal at the input. This could be caused by bad cables or the Input Sensitivity (2) being set to
zero. If this LED is green, then a signal is present at the input. If the LED is red, this indicates that
DDT compression is occurring. When DDT compression is disabled a red LED indicates signal clip-
ping.
