Ved nærmere undersøgelse på arcdb.com så står der følgende : Head amp (optional): 5 Hz to 100 kHz (-3 dB) Head amp (optional): less than 50 nV equivalent input noise with 10 ohms
input (RIAA weighted) På en anden side audiotools.com Head Amplifier An Amplifier that brings the I/O of a transducer
to a common standard. While it may be confusing why a tape head amp
always includes corrective EQ while a moving coil pickup head amp never
has any such this has a really simple explanation, it's the standard
they are amplifying to that dictates it, a pickup head amp is
amplifying a signal to that of an common MM input of a amplifier that
is already specified to have a corrective EQ onboard, while the tape
head amp is bringing a signal to a line, pro or microphone level
standards and all of them expect a straight signal and thus the preamp
needs to perform any necessary alterations to the transducer signal
before going any further. The term "head amp" comes from electric
record cutters, but you had to buy an amplifier to suit the transducer
which was called a cutter head and since the transducers of tape
recorders were called heads as well the name stuck for all transducer
amplifiers that amplify to or from a level signal. Så dermed er den til en Riaa!
