Theta Digital Releases 2nd Generation
of
Acclaimed Dreadnaught Power Amplifier
Upgraded Power Supply and Built-In Citadel Technology Set New Sonic
Standard for Multi-Channel Music and Home Theater Amplification
AGOURA HILLS, CA,
Aug. 15, 2002--Theta Digital, long acclaimed as America's most advanced
manufacturer of high-end digital audio and video products, has built
on the success of its top-rated Dreadnaught amplifier to introduce
the sonically improved and visually enhanced Dreadnaught II Power
Amplifier.
Theta's most significant change was made to
the original Dreadnaught's amplifier modules. Employing technology
developed for its world-class Citadel Monoblock Amplifier, Theta
improved the Dreadnaught's overall sonic performance, resulting
in better imaging and reduced background noise. Superior low-level
detail and improved bass definition provide major advantages for
the reproduction of both two-channel music and movie soundtracks.
The Dreadnaught II's internal electronics
are built on a four-layer circuit board with dedicated layers for
the ground plane and each supply line, ensuring better isolation,
quieter performance, and improved dynamic speed and impact. This
design also significantly improves the symmetry of the balanced
plus (+) and minus (-) signal paths.
The design of the Dreadnaught II's power supply
also underwent a significant upgrade. The single transformer in
the original Dreadnaught was changed to two transformers, both torroid,
in series for the Dreadnaught II. More capacitors were added to
better regulate the power supply. Additional internal bypasses have
been provided for both regulated and unregulated supplies.
The Dreadnaught II's power supply acts as
a huge reservoir, allowing power to be distributed to each module
as needed. Any single channel confronted with a full-level signal
will have the entire current capability of the transformer at its
disposal. In fact, in single-channel power tests, the power transformer
does not limit the output power. Unless all modules are driven to
full power (which never occurs in real-world situations), the channels
not being driven hard effectively lend their portion of the transformer's
power to the more active channels.
Each module contains LED indicators for fuse
and temperature status. Locking XLR jacks ensure a tight, secure
connection. New damping technologies and placements reduce resonance
and mechanical noise.
Output connectors are Cardas Rhodium binding
posts in the single-channel module, and gold-plated binding posts
in the two-channel module. CE-approved versions are supplied to
countries within the European Union.
Each module also incorporates a buss selection
for stereo or surround modes, so that when a user selects stereo
mode from his Theta surround processor, all the energy from Dreadnaught
II's massive power reservoir will be focused on the needs of the
active channels.
Like its predecessor, the Dreadnaught II can
be outfitted with either single- or two-channel modules for up to
ten channels of fully balanced power amplification. The single-channel
module now provides 225W into 8 Ohms, with all 5 channels driven
full out; and over 250W if fewer channels are being driven. One
channel driven into a 4 Ohm load delivers 450 Watts. The two-channel
module delivers a robust 100 Watts per channel into 8 Ohms. All
amplification channels are stable down to 2 Ohms. Both modules accept
input on XLR and RCA connectors.
All Dreadnaught II's undergo rigorous testing
and an extended burn-in period to ensure high reliability.
The modular design that has become a Theta
trademark ensures total flexibility and upgradability in both amplifiers
and preamplifiers. Current Dreadnaughts may be upgraded to the performance
standards of the new Dreadnaught II.
The Dreadnaught II Power Amplifier is available
now from authorized Theta dealers. Configurations from two to 10
channels are available.
