The Truth Pre Amp
- It has an input impedance too high to measure, output impedance is a couple ohms, bandwidth is to 60Mhz, slew rate is a couple hundred V/microsecond.
- There are no capacitors or resistors (other than the photocell) in the signal path. There is no potentiometer in the signal path.
- It uses photo cells to control the volume. It does not use optocouplers.
- The Truth has a balance control that is not in circuit and the balance does not shift with volume changes.
- It is an "active" device and suffers none of the "problems" that "passive volume control or pre amps" have. It can drive long (30 feet) cables with ease.
- It can run 2 outputs.
- I've had parts of this circuit run for 17 years without a buffer failure failure.
- The Truth was first built in 2010. It is tried and true.
- As far as I know there is nothing like it available for any price.....I could be wrong but I doubt it. I looked "pretty hard and long".
- The price in a black aluminum enclosure is $1050 for single input with OCC copper wire. Single input with OCC silver wire is $1100. Each additional copper input adds $40 to the base price. Each additional silver input is $80 added onto the base price.
- Adding a remote is $100.
- Please call me with any questions........also, there are a couple threads on my forum which may be of interest.
