Default TA3020V4-400

TA3020V4-400: 0.02% THD+N @ 112w @ 8 OHMS

For my use the TA3020V4-400 would basically be a 100W amp.

Can you post some FR, POWER v THD+N curves? None in the PDF.

Besides one review at your site are there any other comments about how this amp "sounds".

Can it be mounted vertically on the back of a speaker (thermal considerations)?

What is the best "sounding" amp you sell? (low distortion and noise, "audiophile" etc.)

I can't seem to find or figure out your email from this site or your company sites (probably should add an email me tab) so at the risk of getting excess mail, please send the info to riedlse at gmail dot com.

Default Note to Cristi

Please put an email link on your site or email me. I could really use the amp I ordered ASAP.

Default IRS2092 Modular Amplifier

This amp looks very interesting. I see that this is a new product for you. Are they ready to ship now, in all power levels?

I assume that the supply voltage ranges that are mentioned on the product page are (a) the lower voltage is the min to reach that power level and (b) the higher voltage is the max recommended supply voltage for that configuration? Can a slightly lower voltage be used, e.g. for the 400W version, can a DC supply of +/- 58-60V be used without any problems (just lower output power)?

right now i have modules on stock from each power version. the voltages mentioned are the normal operating voltages, below or above, the under-voltage or over-voltage protection will mute the module. to get the nominal power, the module should be supplied at the nominal voltage which is at the middle of the interval. if lower voltage is needed, please contact me to change the UVLO level.

Default TA3020v4 for bass guitar power amp

I am looking at the TA3020v4 as a power amp for two bass cabinets.

The cabs are 1x12 built around the eminence kappalite 3012LF. Around 450W rms @ 8ohms each.

My plan was to run the module in BTL which should meet my power requirements easily.

My questions are
-Would the TA3020v4 serve my purpose well or is there a better option.
-Would this module be able to withstand Pro audio type usage on a regular basis.
-What differences in performance would I expect between this module and a similarly spec'd PA power amplifier (I am currently using a Crown XTI2000 in dual mono)

Thanks for any help.

Still no answer!! Type and voltage rating would be nice to know. Is 16 volt enough or 35 volt as the caps onboard? Should it be bipolar or electrolytic or does it matter at all? If electrolytic capacitor what about polarity?
