Features
‘Class-T’ Design
‘Class-T’ Digital Technology allows the D400 to
deliver its full rated power from both channels
simultaneously and is 85% efficient so that the
amplifier does not waste energy producing excessive heat.
ELAN HOME SYSTEMS
Digital Level Set/Lockout
All channel levels are matched to within 0.3dB,
making setup easy, accurate, and repeatable.
Level settings are stored within the D400's nonvolatile memory upon exiting setup. This means
that settings are preserved even when a power
outage occurs.
ACE™ (Automatic Clip Eliminator)
Microprocessor-controlled dynamic leveling circuit
eliminates clipping without audio degradation typical with traditional compressor-based clipping circuits. Each amplified output is continuously monitored for signal clipping. Extremely fast transients
are ignored but if ACE sees a consistent clipping
trend, it turns the respective channel down by one
increment. This action is repeated until no more
clipping is detected. Once clipping is absent for
five seconds, ACE will slowly and unnoticeably
begin to restore the original gain settings. This
translates into accurate, high quality audio reproduction at all volume levels.
Vacuum Florescent Display
Blue Signal Presence LEDs show when audio is
present on each input. Red Clipping LEDs indicate distortion, and make fine tuning the amplifier
very straightforward. The Signal Level and Power
LEDs feature adjustable brightness.
A special multi-button key press can be used
to lock the volume settings so that they can not
be tampered with. The user may view their settings when the system is locked, but is unable to
change them.
Advanced Amplifier Protection
Each channel of the D400 is coupled to its respective modular speaker terminal via a high-power
relay. If the processing circuitry senses a fault
condition (over heating, shorted output, etc.), it will
completely disconnect the amplifier channel from
the output load. Faulted conditions will be indicated on the front panel display. After powering down
and finding and correcting the problem causing the
fault condition, the D400 will resume normal operation upon power up.
Single Rack Height Design
The D400’s single rack height design uses space
very efficiently while still producing an abundance
of power.

‘Class-T’ Digital Technology
Explained
The ultimate objective of any audio amplifier
design is to make a high fidelity amp with high
efficiency and high reliability. There are several
basic audio power amp topologies that have been
developed to attain these objectives: Class-A,
Class-B, Class-AB, Class-H, Class-G and
Class-D are the most common. The D400 utilizes proprietary Class-T topology from Tripath™.
Class-T combines the best attributes of several of
these designs and minimizes deficiencies in each
design, as well.
Class-A, Class-B and Class-AB amps have been
around for over fifty years. Basically, these classifications designate the amount of time that the
amp’s output devices conduct during one full cycle
of a periodic signal. Class-A amps are in a state
of conduction 100% of the time. Class-B amps
have a complimentary pair of outputs, which are
biased so that each output is conducting only 50%
of the time. Class-AB amps also have complimentary output pairs but they are biased so that each
output is conducting slightly more than 50% of the
time: this lowers crossover distortion. The vast
majority of audio amps in use today are Class-AB.
A well-designed Class-AB amplifier has good linearity (high fidelity) and poor efficiency (less than
50%). Class-H and Class-G are both voltage-supply varying techniques which are usually applied to
Class-AB type, linear amplifiers. These techniques
give marginal improvement in efficiency at the cost
of a more complex and less reliable power supply.
Class-D amplifiers use output devices which
switch on and off at a fixed frequency. This frequency is usually more than ten times higher than
the highest frequency to be amplified. A passive
filter reconstructs the wave form passing through
the amplifier and removes switching artifacts
that distort sound. Class-D amplifiers use output
devices that are either ON or OFF; never in a state
of mid-conduction. This mid-conduction state is
what causes linear switching amplifiers to be as
inefficient as they are (less than 50% efficiency).
Class-D amplifiers are approximately 85% efficient:
a 35% increase!
D400/D401 INSTALLATION MANUAL
ON/OFF timing results and crossover distortion
issues. Ground Bounce caused by high-current
switching of the output transistors manifests itself
as noise on the audio output. In some Class-D
amplifiers, this high-frequency noise is not completely filtered out, resulting in high frequency
distortion.
Advantages of Class-T Design
Class-T is a combination of Adaptive Digital Signal
Processing and Spread-Spectrum Switching. This
design takes the efficiency of a Class D amp and
combines it with the fidelity of a Class AB amplifier
by dramatically improving signal integrity.
Class-T offers the following improvements over
Class-D:
1. Class-D has a fixed output switching frequency.
Class-T has an adaptive switching frequency
which is dependent upon both input signal
frequency and magnitude. Switching artifacts
are removed in this way, reducing distortion.
The switching signal is constantly being
optimized to match the input signal in order to
yield the highest possible fidelity.
2. Class-D amplifiers have nominal switching
frequencies between 200kHz and 300kHz which
creates artifacts in the 20 to 50kHz audio band.
This can be heard as audible noise. Class-T
amplifiers have nominal switching frequencies
between 600kHz and 700kHz; artifacts from this
frequency are not audible.
3. Class-T design constantly monitors the output
transistors and adaptively corrects for varia tions between and within these transistors.
The Class-T design also monitors and corrects
for ground bounce that the transistors produce
when switching large currents.
4. Typical power efficiency with a Class-T amplifier
is 85% (unreachable by Class-AB amps).Typical
THD + Noise is less than 0.04% (unreachable
by Class-D amps.) Truly the best of both worlds!
As mentioned, each of these amplifier designs
has drawbacks. Class-D amps have tendencies
toward high distortion rates. Crossover distortion, ground bounce, and high frequency artifacts
create most of the distortion in these designs.

Volume Controls
Although it is possible to construct a simple stereo system utilizing one pair of
speakers and a volume control, this amplifier is designed to run best directly
connected to multiple speakers that all ramp volume up and down together.
Most applications that are utilizing the full power potential of this amplfier are
NOT APPROPRIATE for volume controls! Damage may occur to volume controls and the D400 if incorrectly configured.

VCs
Parallel Speaker Outputs
The D400 is a two channel amplifier with six speaker output terminals. Each
pair of terminals is internally wired in parallel with the other pairs. Speaker
outputs 1, 3, and 5 are common; speaker outputs 2, 4, and 6 are common.
Please remember that when additional pairs of speakers are connected to the
amplifier, the impedance drops in half and the output of the amplifier increases
significantly. This is critical when determining the maximum power handling of
a particular speaker.

Setting Channel Levels
Each amp channel can be individually adjusted
from the front panel. Pressing the C button will
toggle between the amp channels — Left and
Right channels can be adjusted independently.
The C button to the left cycles downward, the one
on the right cycles upward. When the desired
channel is displayed on the front panel, use the V
buttons to adjust the level for the selected channel. The V button to the left lowers the volume,
the one on the right raises the volume. Factory
Default is 50.
Set the levels by first lowering them all the way
down, then raise the volume of any keypads
or volume controls to maximum. Slowly adjust
Volume Up for this channel until the red clipping
LEDs begin to light up, then drop the level one or
two steps. Follow this procedure for all channels.
Lockout Mode
The Lockout feature is designed to disable all front
panel functions. Use this feature once the system is fine-tuned and ready-to-go. By locking the
D400’s front panel, level adjustments cannot be
inadvertantly changed.
To place the D400 in Lockout Mode:
1. With the Front Display dark, Press C- and Vsimultaneously.
2. Continue pressing C- and V-. The Front Display
will show the Volume setting momentarily.
3. Four seconds later, the Front Display will read
