CARVIN ENGINEERING DATA
OPERATING MANUAL
The HD power amps deliver exceptional sound/reliability, ultra-light weight
9lb (4.1kg) and it’s made in the USA. You’ll appreciate the ultra-light feature,
which comes in part from its heavy-duty aluminum frame. High power, un-
compromised sound and maximum reliability is at its best for both touring
systems and fixed installations. The concert stage is the ultimate test of profes-
sional audio. Concert audio has to be uncompromising, reliable and efficient
and that’s where the HD performs night after night, year after year. The HD is an
American made workhorse backed by 40 years of manufacturing excellence.
HIGH POWER TOPOLOGY
The CLASS D topology features high current MOSFET output devices produce-
ing huge output currents when needed while delivering high slew rate perfor-
mance for crystal clear highs and chest pounding bass – every note is vibrant,
pure and natural. The HD’s headroom reveals its high dynamic power from
the Switchmode power supply that operates at 100,000 Hz. The high efficient
Switchmode supply is a league above toroids saving not only AC power from
the wall but reducing internal heat. The HD easily handles the most difficult
mismatched or reactive loads and is AC generator friendly. The soft-start gently
turns the HD on to prevent tripping AC breakers.
COOL EFFICIENT DESIGN
The Class D output design raises power amp efficiency to the xtreme. The high
efficiency heat transfer system offers the most advanced cooling. Together
these features are the keys to the HD high reliable power. The internal aluminum
heat sink is nearly running cool with just convection, but the added multi-speed
fan keeps it cool and runs quiet under 2 ohms loads in high power operation.
Air is pulled from the rear and exhausted to the front to keep the rear of your
rack cool.
FRONT PANELS & CONNECTING UP
The HD Series feature front panel signal ladder, peak, protect, and bridge LEDs
which let you monitor the status of the amp fast. Both channels use detente
level controls allowing you to see your settings at a glance. Balanced TRS & XLR
input connectors are used to eliminate hum & noise. Speaker outputs feature
heavy-duty binding posts, and combo Speakon™ and 1/4” jacks.
The rear professional accessory group offers a PARALLEL input switch connects
the inputs together eliminating Y cables for patching multiple amp systems. The
accessory group also features a BRiDgE MODE switch to deliver twice the power
into a “mono” load or a 70V distribution system, and a 100Hz 18DB/OCT LOw
PASS CROSSOVER switch for each channel for fast Subwoofer setups.
CONSTRUCTION
The HD construction starts with a heavy 2RU aluminum chassis. All printed circuit
cards are double-sided FR4 military-grade fire retardant with plated through holes
- soldered under, on top and through each component. SMT - surface mount
technology offers “shock-proof” protection. The CB and CE safety seal assure that
each HD meets strict standards for service anywhere in the world. Auto switches
from 120VAC 60Hz or 240VAC 50Hz - no manual switch to change.
