- GG Audio Design is a small and very flexible firm for design and manufacturing of audio equipment. The products are made in small series and mostly to individual orders.
When recording specifically for vinyl records the low frequencies are suppressed and in order to achieve an even linear frequency response at reproduction they need to be suitably raised. This requires the cartridge to be connected to a preamplifier for frequency correction.
frequency suppression in audio recording is
required for limiting the information per
unit recording area. Without limiting the
low frequency amplitudes the width of the
grooves and their separation will become too
big. In addition the nonlinear distortion
will increase and the signal to noise ratio
for high frequencies will worsen.
