Tech 21 POWER ENGINE 300 - Manual (Page 2)

T ECH 21, THE COMPANY
Tech 21 was formed by a guitarist possessing the unusual combination of a trained
ear and electronics expertise. In 1989, B. Andrew Barta incorporated Tech 21 and
made his invention commercially available to players and studios around the world.
His highly-acclaimed
SansAmp™ pioneered Tube Amplifier Emulation in profes-
sional applications for recording direct and performing live, and created an entirely
new category of signal processing. While there have since been many entries into
this niche, SansAmp continues to maintain its reputation as the industry standard.
After developing a full line of SansAmp models, Tech 21 expanded its offerings to
include effect pedals; a compact, battery operable MIDI footcontroller, the
MIDI
Mouse; as well as “traditional” style amplifiers for guitar and bass. Each product
is thoughtfully and respectfully designed by B. Andrew Barta himself with the
player in mind.
Our goal is to provide you with flexible, versatile tools to cultivate, control, refine
and redefine your own individual sound. Tech 21 takes great pride in delivering
consistent professional quality sound, studio to studio, club to club, arena to
arena.
P OWER E NGINE S ERIES, AN OVERVIEW
The Power Engine Series concept began as a simple, all-purpose 1x12 open-back
powered cabinet. The goal, initially, was to provide pure, transparent sound to
amplify our own line of SansAmp Tube Amplifier Emulators after having to address
the most often asked question, “Which amplifier should I use with my SansAmp?”
During the engineering process, the Power Engine evolved into a stand-alone “pre-
amp amplifier” that could be used with any direct recording device or preamp from
any manufacturer. The Power Engine was also designed to complement our
Trademark Series of traditional amplifiers for players whose volume requirements
vary from gig to gig.
The next most often asked question was for those with SansAmp rackmount mod-
els: “Which power amp should I use?” It became apparent we should build our
own
instrument power amplifiers for large-venue capacity.
Both formats, 300-watt/4-Ohm mono or 400-watt/8-Ohm stereo, fit into a 2U rack
space. The oversized power supply with a toroidal transformer delivers pneumatic
punch with a natural transient response for tone that is uncolored and unaltered.
These costlier transformers are lighter in weight and reduce stray magnetic fields
that cause interference and hum.
Each model is touring tough and super-reliable. Top-quality Toshiba power transis-
tors and a heat-sensor equipped cooling fan furnish non-stop, full RMS-watt power,
rather than pulse or peak power.
IMPORTANT SAFETY INSTRUCTIONS.
READ AND SAVE THESE INSTRUCTIONS.
HEED ALL WARNINGS.
This unit is powered by potentially hazardous voltage. Therefore, observe
the following safety precautions:
1. Read and follow all instructions before using product.
2. Do not use product near water (such as near a bathtub, washbowl, kitchen sink,
swimming pool, in a wet basement, etc.).
3. Unit should be located so that its location or position does not impede the flow of
air through the ventilation openings.
4. Product should be located away from heat sources such as radiators, heat registers,
or other products, including amplifiers, that produce heat.
5. Product should be connected to a power supply only of the type described in the
operating instructions or as marked on the product.
6. Protect the power cord from being walked on
or pinched particularly at plugs, convenience
receptacles, and the point where they exit from
the unit.
7. Do not allow objects or liquids to penetrate
the enclosure through openings.
8. During heavy use, chassis may get hot to the
touch. Handle with care.
9. Protect unit from strong impact.
10. Unplug product before cleaning. Never
spray liquid cleaners into the amp: wipe with a
clean, lint-free cloth to remove dirt and film.
11. Only use attachments/accessories speci-
fied by the manufacturer.
12. This product should be used only with a
cart or stand that is recommended by the manufacturer. When a cart is used, use cau-
tion when moving the cart/product combination to avoid injury from tipping over.
13. Amplifiers may be capable of producing high volume levels that could cause per-
manent hearing loss or damage, if the exposure to such levels is prolonged. Such dam-
age is progressive and irreversible! If you experience any hearing loss or ringing in the
ears, consult an audiologist.
14. Unplug unit during lightning storms or when unused for long periods of time.
