Sure simple, what comes out of 99.9% of hiend poweramps is SE (single-ended), the speaker terminals are + positive and negative is at ground potential. Cheers George. |
BTW, that opamp chops a full audio sign-wave into a negative and a positive,Huh?? No it doesn't. An opamp has two inputs, inverted and non-inverted, and otherwise is a DC coupled amp with very high gain. for audio purposes, to control the gain and allow the opamp to operate in a linear fashion (otherwise the output tends to spend a lot of time at one rail or the other), feedback is applied. The resulting gain is thus then the ratio between the input resistor in series with the inverting input and the value of the feedback resistor. It does not chop the signal or anything like that- the output is single-ended, and in phase with the '+' input and out of phase with the '-' input. |
