CARVIN ENGINEERING DATA
OPERATING MANUAL
The HT150 professional amp is designed utilizing Carvin’s 33
years of experience in power amp technology. It meets and
exceeds every standard for professional amplification. The thick
brushed anodized aluminum face plate, large recessed knobs and
heavy-duty steel chassis reflect the manufacturing quality within.
The HT150 “High Energy Transfer” amp carrys the CE approval
for world-wide use.
PURE—TRANSPARENT SOUND
Carvin considers the sound of an amp equally important as its reliabil-
ity. To insure pure, uncolored sound, we designed one of the fastest
responding power amps on the market today. High slew rates deliver
superb transient response. High frequencies are transparent and open—
even at extreme levels. Linear feedback circuits reduce distortion to near
the theoretical zero limit, preventing any type of harshness which would
lead to ear fatigue. The HT150 amp delivers flat, transparent, unaltered
sound—especially important to the studio user. These amps are designed
to deliver non-stop, continuous power and are completely protected from
heat and short circuits.
ULTRA RUGGED FOR TOURING
Every chassis is made from heavy-duty 16 gauge aluminumthat is
light-weight and prevents rust. All internal cabling is neatly tied and
harnessed. Neutrik™ XLR connectors, heavy-duty power switches,
recessed knobs & machined aluminum front panels all give the HT
amps a “tank-like” ability to handle rough, touring transport.
TOTALLY MODULAR
With the HT150, Carvin brings you totally modular construction. If
you ever need an I/O (input/output) connector card because a connector
wore-out, just unplug it and re-install the replacement card in minutes.
You don’t have to de-solder anything. This applies to every aspect of
the HT150 amp including the power supply, power cards, heat sinks
and fans. Everything is connected by heavy-duty connectors for easy
replacement—even the Toroid transformer is a total plug-in.
LOSE THE WEIGHT...NOT THE PERFORMANCE
For some companies weight reduction means cost reduction. Carvin
however, uses expensive TOROID transformers to reduce weight.
Toroids deliver extra amounts of “on demand” current for continuous
operation. This gives the power supply a solid foundation, yielding more
headroom. Not only do toroids deliver high current, but they are known
for reducing stray magnetic fields eliminating hum & noise. This is espe-
cially important for the recording industry.

HT150 POWER AMP
FRONT PANELS & CONNECTING UP
The HT150 features front panel signal, peak and protect LEDs which let
you monitor the status of the amp easily. Also, both channels use preci-
sion 41 detent level controls allowing you to see your settings at a glance.
The EQ expand switch offers “loudness compinsation” by adding additional
bass and treble to improve your sound, especially at lower levels. Balanced
1/4 phone & XLR input jacks are used to eliminate hum & noise. Speaker
outputs feature 1/4” jacks & heavy-duty binding posts that accept up to
50 amp #7 speaker wires. A bridge mode switch allows the HT150 to deliver
its full power into one speaker.
