ceramic to line

[bobcat]

Ok everyone this is going to sound daft, but i have av high quality audio mixer which has two inputs switchable between mag & ceramic cartridge inputs, what i want to do is retain the mag input but convert the ceramic to a line input ! any ideas or circuits would be greatfully appreciated.

It all depends on how your RIAA EQ network is built into the circuit. You would probably want to rewire your selector switch and bring in the LINE-IN at the "end" or nearly the end of your gain stages.

Post a schem???

There is a high probability that the "ceramic" phono input is already a line level input.

Hi Hanginon is there a set standard for ceramic cart output or should ijust try it by pluggingin acd player and listening to se whether it over drives the signal/
B/c

Hi,

It is highly likely it is a effectively a line input. Ceramic cartidge output
varies a lot, from 50mV to over 1V, though 100mV to 300mV is typical.

The only difference to a normal line input is input impedance, which
is in the few Megaohm range, meaning it will be somewhat noisier
than a lower impedance line input.
