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

for Mute, when is connected to GND will mute the amplifier, left open will work normally.

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?

Default 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.

Default 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.
