Hello,
I have recently purchased a Mcintosh MC7300 amp with VU meters. I purchased it from audio classics and they have tested everything and it all meets spec. I am using a decibel meter to see how many watts it takes to get my JBL L-112 to play at 85db level at my listening position.
I would think that when using the same speakers and test track that it would take the same amount of wattage from both the Sansui and the Mcintosh to achieve the 85db reading at the listening position. This is not the case though.
I am assuming that the reading on the Mcintosh meters is correct since it has just been tested and meets spec 100%
What I am wondering is why I am not getting the same wattage reading from both units to achieve the same decibel reading. It is reading a higher wattage on the Mcintosh unit.
The sansui unit is right under 1 watt to get 85db at my listening chair. The Mcintosh is right about 2 - 2.5 watts. I feel like the sansui is making more power than what is showing on the meters.
Is there a way to test and calibrate the meters on a Sansui 9090? How accurate are the meters on a 9090? Have any of you guys ever seen this?
