- Page 4 NOTES ON TAPE Tape Recorders were first used by professional recording studios in the late 1940’s, soon after WW2. They were adapted from the German Magnetofon that had been used by the German Navy to improve security of communications with their submarines.
- Page 5 the 542’s tape circuit can significantly impact tone, depending on the position of the saturation control and the drive level on the tape circuit. As saturation is increased, low frequency compensation is decreased, and at a drive level of 5 the soft clipper enters the circuit.
- Page 6 function can be useful on many sources like bass and kick drum to find the balance between a clean, boosted low end (low saturation) and a denser, more saturated low end (high-saturation). 15/30 IPS Selects the pre-emphasis / de-emphasis, record / replay tape characteristic. The 15IPS mode has a significant “head bump”...
