CA-D200 200W Stereo Amplifier
Information
The CA-D200 is a new and innovative amplifier design that uses what are called switching technologies. Switching amplifiers and power supplies offer many advantages but present different challenges and a higher degree of complexity than conventional linear designs. Their potential is too great to ignore, however, which is why the Classé Design team now includes engineers with over fifty years combined experience in switching amplifier and power supply design. The result is the CA-D200, the first of its type from Classé; the first of its type—period.
Switching Power Supply
A new Switch Mode Power Supply with Power Factor Correction, provides over 1,000W of clean, stable power to the CA-D200 amplifier circuitry. The SMPS and PFC each operate at over 90% efficiency, yielding impressive benefits for power delivery. The low frequency dynamics, extension and control of the CA-D200 and its ability to effortlessly drive difficult speaker loads can be credited in large part to the powerful and sophisticated power supply it employs. The SMPS with PFC is ideally suited to the demands of the CA-D200’s revolutionary switching amplifier topology.
Switching Amplifier
Some technical limitations have been commonly accepted as inherent in switching amplifiers—until now. Perhaps the biggest limitation is called dead-band time, which translates directly to distortion and tempts designers to employ excessive amounts of negative feedback to compensate. With its proprietary drivers and DSP tools, the Classé Design team solves the dead-band time problem with precision and consistency for each and every CA-D200. On power up, controller circuitry analyzes and adjusts to minimize the dead-band time for each pair of outputs. In this way, part tolerances and drift for each individual amplifier are taken into account. Lastly, the feedback loop is closed using the least amount of negative feedback required. Our linear phase output filters are then employed only to filter the 384 kHz switching frequency, not to roll off the top end of the audio band, as is often done to try to make amplifiers with high dead-band time more listenable. The result is a wide and deep soundstage with extended high frequencies that reveal a musically detailed and open midrange and top end.
Summary
The CA-D200 employs proprietary component parts and DSP technology along with sound engineering practice to optimize its sonic performance at an affordable price of admission for a Classé amplifier. Listen and hear for yourself how beautiful great value can sound.

How to check the current Firmware of your CA-D200
- If the CA-D200 is connected via CAN-Bus (to a SSP), you can check the installed Firmware Version using the Status Screen of your Classé Surround Sound Processor.
- If you have no CAN-Bus connection to verify the Firmware Version then we advise you update the Firmware using the Procedure below in any case. It will take only a minute.
How to update Firmware on a CA-D200
- download the latest Firmware package
- unzip the downloaded file on your local computer
- copy the unzipped file onto a new USB key. This key must be empty. The file must be located at the "root" level
- power off your CA-D200 using the Power switch on the rear of the unit
- insert the USB stick in the front USB port
- Power on the CA-D200 using the power switch in the rear of the unit
- the Firmware update will start automatically and will take less than a minute
- When finished the unit will go into Standby (solid red LED)
What to do when your Firmware Update fails
- simply power down the unit and remove the USB key, the unit will revert back to its previous Firmware Version when your power on again;
Then what...?
- Our first suggestion is to try again using the same USB key;
- If the Update Fails once more, we suggest that you get a new, clean USB key and try again. We have seen updates fail because of fragmentation of the USB key, or because of vendor-specific key issues.
- If the Update still fails, we ask you to send us the APP.LOG and BOOT.LOG files that you will find on the USB Key:
- insert the USB key into your local computer and open the USB key (file explorer)
- you will notice that 2 LOG files have been written to the USB key.
- Copy these log file to your local computer.
- Please send them to Classé Tech Support for further evaluation, with the Serial Number of the unit.
Installation Tips
- All Sigma AMPs can either be installed "Stand Alone" or in a 19" rack. The side panels have been conceived in such a way that, when inverted, they serve as solid rack-mounting ears for installation in a 19" rack. See pages 5 and 6 of the Owners Manual;
- Make sure that the Sigma AMP has clearance in the back for the attached cables;
- We also suggest to position it well away from source components and preamps/processors that may be sensitive to Electromagnetic Fields;
- Do not connect and disconnect speakers on ANY amplifier whilst the unit is switched on, in order to avoid unpleasant and potentially damaging DC (Direct Current) Noises and short circuits.
CAN-Bus & Triggers
Sigma AMPs can be controlled in a number of different ways, other than using the Front LED Button. Please note that a Sigma AMP has protection circuitry that will not allow the unit to be powered on directly after being powered off.
- CAN-Bus
CAN-Bus stands for " Controller Area Network (CAN) Bus". Classé's implementation of CAN-Bus allows for communication and control between Classé components. All you need is to connect the CAN-Bus port as a "daisy chain" and make sure the last unit connected has a "terminator" on the CAN-Bus out.
Note that older Models of Classé equipment may not recognize the newer Sigma SSP Series. In case of doubt, please contact Classé Tech Support. - IR - in and out
The IR in and output port allow for an electrical IR signal to control the "standby" and "operate" mode on a Sigma AMP. This is not an infrared signal, but a electrical signal obtained by using standard IR receivers, distribution amplifiers, and emitters (available from your dealer) that will translate the remote’s flashes of infrared light into corresponding pulses of electricity. - DC trigger
Sigma AMPs will consider the constant presence of a 5V-12V DC signal on the DC input as an "operate" signal. The unit will go into standby when the DC voltage is absent. - RS-232
Sigma AMPs can be controlled using RS-232, a protocol used by Home Automation Systems like Crestron, Control 4, etc.The Sigma AMP is equipped with a RJ-45 port for this purposes. Event though the RS232 connection is made using Ethernet cable, the actual signal is not "RS232-over-IP", but a standard RS232 signal.
For control systems equipped with an (older) DB9 output port, you will need to use a DB9 (female) to RJ 45 (female) adaptor. See the Sigma AMP Owner's Manual.
Wake-on-LAN, Auto Standby and Global Standby
It has come to our attention that some customers are taken by surprise when "a Sigma unit -- or multiple Sigma units -- shuts down by itself", or when a Sigma unit "does not power on when a network command or CAN-Bus command" is sent. This behavior is the result of the interplay between three features: Wake on LAN, Auto Standby and Global Standby.
We herewith explain the features and indicate how each of them can be changed individually.
Wake-on-LAN (WoL)
All units that ship to member countries of the European Union have Wake on Lan DISABLED in order to comply with European "Standby Power" Regulations. That means that the unit will not react to Network nor CAN-Bus commands once it is in Standby; the Communications Module is inactive. This can be changed using the Front Panel LED button (See below).
Auto Standby
All Sigma AMPs worldwide ship with Auto Standby ENABLED. This means that the amplifier will go into Standby (power off) if there is no (significant) audio signal for approximately 15 minutes. This feature can be disabled using the Front LED Button.
Global Standby
All Sigma AMPs worldwide ship with Global Standby ENABLED. Units that have Global Standby enabled will work as a "collective": if one unit goes into Standby, the other units that have Global Standby enabled will follow. Also, please note that this feature will be reset to ENABLED with each Firmware Update.
How to change these settings on a Sigma AMP
A. How to ENABLE Wake-on-LAN
This must be done manually, using the Front LED Standby button of the Sigma AMP.
- The first step is to activate the "Configuration Mode" using the Front LED button:
While holding the LED button depressed, plug in the AC power cord. Once the amber or green LED comes on, let go of the button (make sure you can actually see the light of the button, so put your finger halfway). Do not let go too quickly otherwise the unit will default to standard operation. If you see an alternating Green and Amber LED, you have successfully entered the Configuration Mode. - Once in Configuration Mode, the LED indicates whether each feature is enabled (= solid) or disabled (= flashing).
Wake on Network = Amber LED
flashing = disabled, solid = enabled. - To change from flashing to solid, wait until the color lights up, then press the LED button once and let go. You have now changed the status.
- In order to verify the new Status, wait until the LED passes by again. It will now indicate the new Status.
- To return to normal operation, simply disconnect and reconnect the AC Power Cord.
B. How to DISABLE Auto Standby
This must be done manually, using the Front LED Standby button of the Sigma AMP.
- Enter the Configuration Mode using the procedure mentioned above.
- The Green LED indicates the Status of Auto Standby. Flashing = disabled. Solid = enabled.
- To change from solid to flashing, wait until the color lights up, then press the LED button once and let go. You have now changed the status.
- Follow Steps 4 and 5 outlined above.
C. How to DISABLE Global Standby
This must be done using the CAN-Bus feature of the attached Classé Sigma SSP or CT-SSP/SSP-800.
- Sigma SSP
From the MENU, select STATUS > click RIght Arrow at the top > The CAN-Bus devices now show on screen > Select the unit - CT-SSP/SSP-800
From the MENU, select System Setup > Status > More > select unit > configuration.
Voltage
- The Sigma 2000i can operate on AC Voltages between 110V - 240V.
- Make sure to change the AC Fuse (rear) to match the AC Voltage of your country.
When you change the fuse to accomodate a different AC Voltage, please contact Classé to obtain a new sticker for the back of your unit that indicates the newOperating Voltage. Without this, another user/customer might make a mistake in the AC Voltage and Fuse Value.
Fuse
- The Sigma 2200i has one fuse accessible via the rear panel;
- Make sure that the AC Fuse corresponds to the AC Voltage offered;
