D660/D661 INSTALLATION MANUAL
Features
‘Class-T’ Design
‘Class-T’ Digital Technology allows the D660 to
deliver its full rated power from all six channels
simultaneously and is 85% efficient so that the
amplifier does not waste energy producing exces-
sive heat.
ACE™ (Automatic Clip Eliminator)
Microprocessor-controlled dynamic leveling circuit
eliminates clipping without audio degradation typi-
cal with traditional compressor-based clipping cir-
cuits. Each amplified output is continuously moni-
tored 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 repro-
duction at all volume levels.
Vacuum Florescent Display
Channel and Volume settings are displayed on
a blue vacuum flourescent 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 straightfor-
ward. The Signal Level and Power LEDs feature
adjustable brightness.
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 D660'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 set-
tings when the system is locked, but is unable to
change them.
Advanced Amplifier Protection
Each channel of the D660 is coupled to its respec-
tive 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 indi-
cated on the front panel display. After powering
down and finding and correcting the cause of the
fault condition, the D660 will resume normal opera-
tion upon power up.
Single Rack Height Design
The D660’s single rack height design uses space
very efficiently while still producing an abundance
of power.

D660/D661 INSTALLATION MANUAL
‘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 D660 uti-
lizes 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 clas-
sifications 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 complimen-
tary 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 lin-
earity (high fidelity) and poor efficiency (less than
50%). Class-H and Class-G are both voltage-sup-
ply 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 fre-
quency 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!
As mentioned, each of these amplifier designs
has drawbacks. Class-D amps have tendencies
toward high distortion rates. Crossover distor-
tion, ground bounce, and high frequency 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 com-
pletely 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!

System Expansion
ELAN Engineers had flexibility and system expansion in mind when they
designed the D660. To add additional stereo rooms or zones to a basic sys-
tem, simply add another D660. To expand zones or subzones to include more
than six channels of amplification, use the Buffered Loop Outputs to send
audio to additional D660s or other amplifiers.

Triggers
Each channel pair of the D660 has its own Remote
Turn On/Muting circuit. Individual channel pairs
can be turned on or muted independently of any
others. An “ALL ON” port allows all channels
to turn on and mute simultaneously. The Front
Display of the D660 will show “M” next to the
channel number when a channel is in Mute.
The TRIGGER OUT can be used to turn on other
equipment, additional D660s, or to perform auto-
mated functions desired by the user.
ALL ON
To Mute/Un-Mute all channels simultaneously,
simply connect a system-wide 3-24 Volt AC or
DC Triggering Source to the ALL ON Trigger Input
using a 3.5mm mono interconnect cable. Examples
of triggering sources include an ELAN Multi-Zone
Controller’s SYSTEM TRIGGER OUT or REMOTE
OUT, an A/V receiver’s switched outlet connected
to a power supply, or a TRIGGER OUT from anoth-
er ELAN D Series amplifier.
Specific Stereo Pair Triggers
To Mute/Un-Mute specific pairs of channels, a
zone-specific Triggering Source can be used. As
in the ALL ON example, any 3-24 Volt AC or DC
source may be used to trigger these specific
inputs. This application gives additional control
in advanced systems. Examples include: Zone
Specific Trigger Outputs from an ELAN Multi-Zone
Controller, multiple A/V Receivers triggering sepa-
rate D660 inputs, or outboard sensors located in
certain areas to trigger specific inputs of the D660.
TRIGGER OUT
Whenever the D660 comes out of Standby, the
TRIGGER OUT becomes active. As the name
implies, this output sends a +12V 100mA signal
to other devices with a Trigger Input. Examples
of proper usage of the TRIGGER OUT include
muting/un-muting another D Series amplifier,
triggering the switched outlets of a Z•Power
Controller, or triggering an IR sequence using
VIA!®products.

Setting Channel Levels
Each amp channel can be individually adjusted
from the front panel. Pressing the Cbutton will
cycle through all the amp channels — both Left
and Right channels can be adjusted independ-
ently. The Cbutton to the left cycles downward,
the one on the right cycles upward. When the
desired channel is displayed on the front panel,
use the Vbuttons to adjust the level for the
selected channel. The Vbutton 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.
Protection Mode
Should the D660 encounter a potentially damag-
ing situation (impedance too low, gain too high,
dead short on speaker leads, etc.) it will go into
Protection Mode. The front display will read “E”
(for Error) next to the channel number. If this
occurs, turn off the amp, correct the problem that
is causing the Error condition, then turn the amp
back on.
Lockout Mode
The Lockout feature is designed to disable level
adjustment functions. Use this feature once the
system is fine-tuned and ready to go. By locking
the D660’s front panel, level adjustments cannot
be inadvertantly changed.
To Place the D660 in Lockout Mode:
1. With the Front Display dark, Press C- and V-
simultaneously.
2. Continue pressing C- and V-. The Front Display
will show the Volume setting momentarily.
3. Four seconds later, the Front Display will read
“L” next to the channel number. Release the but-
tons.
4. Follow the same procedure to Unlock the amp.
Please Note: If the user tries to change settings
while in Lockout Mode, the Front Display will show
“L” next to the Channel number.

Volume Adjustment
Considerations w/ACE™
Automatic Clip Eliminator
ACE automatically adjusts the D660’s levels down-
ward when it senses a clipping condition. If audio
is playing and the amplifier is clipping (ACE is
performing it’s function), ACE will override Volume
Up functionality and turn the amplifier levels back
down. Volume Down functionality remains.
To save levels at the point where ACE sets them,
Press the Volume Down button. The new levels
will be saved when the display times out.
Factory Default
When your D660 arrives, it is set to a FACTORY
DEFAULT condition. At some point during the life
of this amplifier it may be necessary to put the
unit back into Factory Default mode. If this unit is
moved to a different location or speaker type or
load are changed, the FACTORY DEFAULT proce-
dure should be used:
1. Turn the D660 OFF using the rear Power
Switch.
2. Turn the unit back ON. The Front Display will
read ELAN.
3. Press and hold C+, C-, V+, and V- (all the
front panel buttons at once) while ELAN is
displayed.
4. The Front Display will now read “FACTORY
DEFAULT”.
The Factory default settings are:
• All channels Volume defaults to 50.
• Lockout feature is Disabled.
Display Brightness Levels
The blue Signal and Power LED brightness levels
on the Display can be increased or decreased
from the Front Panel. Press and hold C+ and V+
to cycle between High, Low, and Off. The Red
Clipping LEDs cannot be adjusted.
