Limited Warranty

Carver Professional provides a limited warranty
on all amplifiers (free of manufacturing defects in

when purchased from an authorized Carver
P rofessional dealer. Please consult your dealer
or the factory for specific warranty information.

pm1400 Architects’ and Engineers’ Specifications

The power amplifier being of two channels, shall deliver 475W into 8 Ω per
channel with both channels operating, and 700W into 4 Ω per channel with
both channels operating. The amplifier shall be capable of bridged-mono
operation thereby providing 1400W RMS output into 8 Ω. The amplifier shall
be capable of parallel-mono operation for low impedance operation, there b y
p roviding 900W RMS output into 4 Ω. Each channel shall be equipped with
c o m p ression circuitry that electronically senses the onset of clipping and
engages a specially-designed circuit which virtually eliminates the possibility
of driving the amplifier into distortion. A switch shall be provided to activate
the Clipping Eliminator circuit for both channels. Internal components shall be
fan-cooled. The fan shall operate at two speeds, the speed being determined
by internal operating temperatures. The amplifier shall have a thermal
shutdown system to protect the power devices from over- t e m p e r a t u re
operation. This thermal protection system shall be self-resetting. A pro t e c t i o n
LED indicator shall illuminate and electronically activated relays shall
disconnect the speaker outputs to protect against over- t e m p e r a t u re, short
c i rcuits, DC offset present at the outputs or an internal power supply fault.
The amplifier shall provide delayed activation of the speaker output relays at
t u rn-on. The amplifier shall have a voltage gain of 30.7dB (1.5V RMS sensitivity),
with a provision for internal jumpers to change the gain to 36.7dB (0.775V
RMS sensitivity). Noise shall be at least 100 dB below 700W/4 Ω A-weighted.

Total harmonic distortion shall be less than 0.1% at 1.5V sensitivity. The fro n t
panel controls shall consist of a master power switch and a fuseholder

containing a replaceable 15A slo-blo fuse. Front panel indicators shall include
a green Ready LED which shall illuminate red when a protection circuit is
activated, five yellow Signal Present LEDs and a red Clip/Protect LED for

each channel. Independent level controls shall be provided for each channel.

The level controls shall have an easily accessible internal defeat switch. The
rear panel connections shall include a 1/4-inch TRS jack and an XLR

connector for the input to each channel. Pin 2 of the XLR connector shall be

non-inverting, providing the option of changing the input polarity with intern a l

jumpers. One pair of multi-way binding posts shall be provided for the output

f rom each channel. An easily accessible internal switch shall be provided for

selecting Normal Stereo, Dual Mono or Bridged Mono operation. A 2-position

s c rew terminal barrier strip shall be provided for operating a sequential turn

on circuit. The dimensions shall allow for standard 19” EIA rack mounting. It

shall be 3.5” high and 13.25” deep. The amplifier shall weigh 34 pounds. The

power re q u i rements shall be 120V, 60Hz for domestic versions, and 230V,
50Hz for export versions. The frequency response shall be +0, -3 dB at 5Hz

and 40kHz. The maximum input current re q u i rement for a 700W output into

4 Ω with both channels operating shall be 20 amps at 120V, 60Hz. The power
amplifier shall be a CARVER Professional pm1400.
