INTRODUCTION
The ELAN D1200 Digital Power Amplifier has been designed from the ground up specifically for
custom installers to provide the ultimate solution for multi-room, whole-house applications. Twelve
channels of clean, powerful audio can be combined in dozens of different ways to suit virtually any
situation that may be encountered in whole-house distributed audio systems. The D1200 uses an
audio bus system that allows inputs and outputs to be combined in many ways without the use of
extraneous patch cables. ‘Class T’ Digital technology and ACE™ (Automatic Clip Eliminator™) allow
efficient use of power, ensuring clean, powerful audio at all volume levels in any application. Remote
triggers and turn-on circuits for each channel enables the installer to integrate this amplifier easily
with any ELAN multi-zone system or in stand-alone applications without additional ELAN equipment.
I. FEATURES
‘CLASS T’ DESIGN
‘Class T’ allows the D1200 to deliver its full rated power from all twelve channels simultaneously
and is 90% efficient so the amplifier does not waste energy producing excess heat.
TWELVE HIGH-POWER CHANNELS
Audio quality is greatly improved when plenty of power is applied to each speaker in
a multi-zone environment. Bass sounds better. Dynamic range is improved. Voices sound
full and rich. The D1200 provides 12 x 100 Watts @ 4 Ohms; ideal for virtually any distributed
audio system. ELAN uses an ultra-high efficiency torroidal transformer and 200,000 uF of bulk
storage capacitance to ensure plenty of power when it’s needed!
UNIVERSAL STEREO BUS
A-Bus and B-Bus inputs and outputs allow the amplifier to be configured in dozens of different
ways to meet the demands of large audio distribution systems. Channels can be assigned to
one of two audio busses in order to be split or combined according to situational demands.
Audio inputs can be A-BUS, B-BUS, Independent, Stereo, or Mono without the use of extraneous
patch cables. Additional amplifiers can be connected from the Bus outputs of the D1200 to
provide greater system expansion.
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.

INDIVIDUAL REMOTE TRIGGER INPUTS/TRIGGER OUT
Six +12VDC Trigger Inputs allow each pair of channels to be powered up and muted
independently. +12VDC Trigger Output turns on and mutes additional amplifiers.
FRONT PANEL DISPLAY AND CONTROLS
High-visibility blue LED display and front panel Channel Select and Volume Adjustment controls
make setup easy. Blue Signal LEDS show when audio is present on each input. Red Clipping
LEDS indicate distortion, and make fine tuning the amplifier very straightforward. Five blue
LEDs fire downward to softly indicate Power status.
DIGITAL VOLUME LEVEL SET AND LOCKOUT
All channel volume levels are matched to within 0.3dB, making volume setup easy, accurate,
and repeatable. Volume settings are stored within the D1200's non-volatile memory upon
exiting setup. This means that settings are preserved even when a power outage occurs. 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 D1200 is coupled to its respective output binding post 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. After finding and correcting the problem causing the fault
condition, simply power the unit OFF and back ON to restore operation.
RACK MOUNT ALUMINUM FRONT PANEL WITH RUGGED HANDLES (D1201)
Amplifier mounts securely to equipment racks. Handles are invaluable when moving, installing,
adjusting or servicing the unit.
CLASS T DIGITAL TECHNOLOGY EXPLAINED
The ultimate objective of any audio amplifier design is to make a high fidelity
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, ClassH, Class-G and Class-D are the most common. The D1200 utilizes proprietary Class-T
topology from Tripath™. Class T combines the best 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 50 years. Basically,
these classifications designate the amount of time that the amps 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 that 50%
of the time; this lowers crossover distortion. The vast majority of audio amps in use today
amp with

D1200/D1201 INSTALLATION MANUAL & USER'S GUIDE ELAN HOME SYSTEMS
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 amps approximately 85% efficient: a 35% increase!
As mentioned, each of these amplifier designs has drawbacks. Class D amps have
tendencies toward high distortion rates. Crossover distortion, ground bounce, and highfrequency artifacts create most of the distortion in these designs. Imperfectly matched
transistors lead to inexact 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.
CLASS T TECHNOLOGY-- WHY IT'S BETTER
Class T is a combination of Adaptive Digital Signal Processing and Spread Spectrum
Switching. This design takes the efficiency of a Class D design 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 switching input.
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 out
put transistors and adaptively corrects
for variations 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 amp
lifier is 85% (unreachable by class A-B
amps,) Typical THD + Noise is less than 0.04% (unreachable by Class D amps.)
Truly the best of both worlds!

B.SIGNAL/CLIPPING INDICATORS
There are twenty-four LEDs on the front panel of the D1200 designated for signal
presence and clipping indication. Twelve blue LEDs indicate when an audio signal is
present on each input. The left most blue LED is channel one, and the rightmost LED is
channel 12. Red LEDs are placed above the blue ones to indicate clipping for each
corresponding channel. Consistent red LEDs indicate over-saturation of the input
signal. Volume should be reduced for the affected channels. See VOLUME
ADJUSTMENTS.
THERE IS NO BENEFIT FROM TURNING THE AMPLIFIER'S VOLUME PAST
THE POINT WHERE THEY CAUSE THE RED CLIPPING LEDs TO LIGHT UP.
