| Threshold T-200. Help me choose a preamplifier For good voltage transfer from preamp to power amp it is better to have a low impedance at the output of the preamp and to have a high impedance at the input of the power amp.We should using a minimum ratio of >1:10 to improve transfer efficien... | |
| Threshold T-200. Help me choose a preamplifier For preamp choice, if you intend to use balanced inputs of the Threshold T-200, be caution of its 2kΩ input impedance! Best to choose a preamp with balanced output impedance 100Ω or less. | |

| Question on Preamp Outputs. @ jasonbourne52 The MC462 has different gain on balanced and unbalanced input. https://www.stereophile.com/content/mcintosh-laboratory-mc462-power-amplifier-measurements | |
| Question on Preamp Outputs. 450watts 8ohms the voltage is 60volts according to ohm's law equations V = I × R and P = V × I or V = √(P × R ) and P = V^2 / R The voltage gain = 60 / 4.2 = 14.3 2.4volts x 14.3 = 34.3volts 34.3volts at 8ohms = 147watts | |
| Question on Preamp Outputs. The bad news is you can't get the max. rated output power from the McIntosh MC462. The good news is the Marantz 8802a won't drive the McIntosh MC462 into clipping and in reality your speakers may not require that much power. | |
