Cristi,
Thank you for CxD400 amps received today. Could you give information on how to plug them (power supply and audio), I haven't seen any documentation on you website ?

Nicolas

Thanks Cristi - please let me know what email to use since your PM folder seems to be full.
Hello Cristi!, I am curently attending a training in China and I whant to know if I can buy some amplifiers direct from you so I can save on transport.
Thanks for fast replaying

Duda, i just sent you mail. my inbox is full and i can't seem to be able to delete the messages.
Catalin, we already spoke by mail.

Hi Cristi , I have the IRS 2092 module.
What are the gnd/on off connectors for, between the balanced signal input connectors?

Thanks Cristi.
I intend to use the amp to power my center chn.My Yamaha AVR amp has a 12 v trigger output to turn on external amps, can you explain what I need to do to get the trigger working with the pspc that I bought to power the class D amp?

last question 🙂 on the aux power supply connection I guess I use Vnn+10 but do I use Sgnd or Vnn for the 0v /gnd connector?
IRS2092 AMP 200W 8ohm
Hi Cristi
I would like to build a stereo amp for my 8 ohm speakers.
My requirements are POUT >=200W and DC protection on board.
What is the version you suggest and the appropriate SMPS for the stereo version?
regards
Giuseppe

200W or more on 8R means at least 400W power rating on 4R. Most of the boards unless specified are rated for 4R load. since the speaker protection is needed, the most suitable amplifier board is IRS2092 modular amplifier Connexelectronic one for each channel, 400W or 600W version supplied from a single SMPS800R +-72V for 8R operation.
If I ran three 400W IRS2092 modular amplifiers for LCR 8ohms speakers could I use the one SMPS800R? Would the output for 8R be 200W per channel?
I am also very interested in the 12V trigger question, as I will run these amplifiers from my AV Receiver as a preamp.

for whatever reason, I didn't get any notification that a new message was posted, and I just saw your question now.
If the total power required by the amplifiers is below or same as the rated power of the SMPS, then the amplifier modules can be supplied with SMPS800R. thus if the 400W version modules are used with 8R load, the output power will be just ~200W on 8R, within the limits.
each IRS2092 amplifier module has mute control pin which is active when is pulled low, or connected to GND. default more is run, so if you want to use a 12V trigger, you need to make a simple NAND circuit using n diodes (3 for 3 modules) one NPN transistor and two 2k2 and 4k7 resistors.

What to pick?
Hi there,
I'm wondering what amplifier modules I should choose for my future setup: openbaffle WMTM needing 3 or 4 channels (3 if I parallel the mids). I specially need some power in de bass department, but would like to use the same amps on all channels. All units are 8R, except when parallelling the mids. It will be connedted to a minidsp 4x10HD.
So my thoughts went out to the IRS2092 Stereo Amplifier, 400w to be on the safe site, two modules powered by one SMPS800R@60V. Wtonof those sets should be able to power my OB's I guess.
But what would be reasons not to pick the stereo modules, but go for the CxD400 or CxD300(not balanced)?

If the required power is in rage of 200-300W on 8R, I suggest to chose CxD300-8R modules. If more power is needed, CxD400 module can be configured to deliver up to 400W on 8R or IRS2092 stereo amplifier, latest version being able to deliver over 700W on 4R or 400W on 8R on each channel.
But CxD300 does not have balanced inputs, CxD400 and the stereo amp does. The question is: what actual use is it, since the IRS has single ended input?

... Well, one of the uses might be high impedance. What are the input impedances of all the amps?
CxD400, CxD250-HP and IRS2092 Stereo amplifier have balanced input, with input impedance 20Kr. CxD300-8R and IRS2092 modular amplifier does not have balanced input and their input impedance is 3K. Their input need to be buffered to provide matched impedance. There are several advantages of using balanced input, the noise imunity is higher, and in multi-channel designs the GND loop effects can be easily avoided or reduced if one of the inputs, usually inverted one is tied to GND at the signal source point. Also it allows easier BTL connection by simply swapping inverted input with non-inverted input of one of the channels which has to be 180* out of phase.
Thanks Cristi, so I'm back at CxD400 or Stereo amp. Can you give us the gain values of the different amps and power options? I'd like to know to match the right gain with the miniDSP output.
The voltage gain for CxD400 400W version is 33.5 or 1.2V input signal sensitivity for full output power. values of gain in range of 28 to 40 (input sensitivity of 1 to 1.4V) can be set by changing the value of one or two resistors.
The CxD400 does only list one supply voltage range. Is that for both 200W and 400W versions?
And what about the gain of the Stereo module?
