When an equalization curve is used, then the VU meter is not consistent with the
effective risk of saturation, as it indicates the signal downstream the equalization.
User should then pay attention to “CLIP” warning appearing even when the bar is not
completely lit. As a general rule, ADC clipping may occur when using equalization at
a VU meter level such as the 2-3 rightmost leds are still off (this indicates a post-
equalization level of -2/-3dB).
9.5. Interfacing a cartridge or a tape head
The
JOPLIN MKII
allows for setting its analog input impedance to 9 different values,
which cover most MM and MC pick-ups requirements. Nevertheless, certain MC
pickups and even tape recorders heads may need different loading.
Due to the
JOPLIN MKII
rear panel small size, there’s no room for a second pair of
RCA sockets to plug loading RCA plugs. Whenever a load is required which is not in
the
JOPLIN MKII
standard set, we suggest to use “T” RCA adaptors, together with RCA
plugs in which the required resistor or capacitor is solded.
9.6. Recording programs
When acquiring on a computer with the
JOPLIN MKII
, a suitable program of application
needs to be used. Several different programs of packages are available for Windows,
Mac and Linux, some of them are freeware, others need to be purchased.
M2Tech
cannot be aware of all the available programs, nor specifically recommend
any of them, nevertheless some indications are useful for the
