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 excessive heat.

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

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 straightforward. 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 nonvolatile 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 D660 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 cause of the fault condition, the D660 will resume normal operation 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 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!

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. 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.

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 system, 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 automated 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 another 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 separate 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 C button will cycle through all the amp channels — both 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.

Protection Mode

Should the D660 encounter a potentially damaging 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 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 “L” next to the channel number. Release the buttons.

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 downward 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 procedure 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.
