## PWR16 amp input sensitivity 7 years 8 months ago #21367

 Skylinestar Topic Author Offline Junior Member Posts: 24 Thank you received: 2 What's the input sensitivity of PWR16 amp? Any reason why minidsp is not making a PWR8 with more beefy amp?? It will definitely be a better match for the DDRC88. The following user(s) said Thank You: DS21 Please Log in or Create an account to join the conversation.

 dreite Offline Platinum Member Posts: 1785 Thank you received: 777 It specifies voltage gain of 25.8 db on the spec sheet. The advertised power ratings for the PWR-16 amplifier are way too confusing for the average user. The channels are derated depending upon how many are used......peak power versus RMS.....4 ohm versus 8 ohm....etc, etc. If you work the various power ratings backwards to yield a sensitivity number it can get confusing. I think the five-channel peak rating probably provides an indication of the voltage clipping point. If I did the math correctly, I think an input of 0.75VRMS would drive any of the channels to voltage clipping. Ultimately, what you have here is a fairly low powered amplifier with lowish voltage gain. Dave.

 devteam Away Administrator Posts: 9163 Thank you received: 1461 Already a good answer from Dave. Here is a bit more: The input sensitivity in SE mode is: 0.92Vrms at 1kHz for 80W into 4 ohm output It is calculated as follows: Output voltage at 80W into 4 ohm = 17.89Vrm Gain of 80AM2 = 25.8dB = 19.5 => Input sensitivity = 17.89 / 19.5 = 0.92Vrms The input sensitivity in BTL mode is: 0.92Vrms at 1kHz for 160W into 8 ohm output It is calculated as follows: Output voltage at 160W into 8 ohm = 35.78Vrm Gain of 80AM2 = 31.8dB = 38.9 => Input sensitivity = 35.78 / 38.9 = 0.92Vrms DevTeam miniDSP, building a DSP community one board at a time.
