SSM2019 preamp
Hi!
I know theres another thread about preamp designs... What do you (the preamps profies...) think about taking an SSM2019 in combination with a SSM2142 as ouptput stage. Would this make a usable preamp for uncritical stuff? Toms, dummy-tracks etc.pp. 60dB gain is more than enough. What quality can I expect? Since the place on a 160mmx100mm PCB is limited what compromises can be made. And which shall not? Thanks Thomas |

I can say the INA 103 is pretty good if you want a one-chip solution. Since the place on a 160mmx100mm PCB is limited what compromises can be made. And which shall not? With the INA 103 the big problem is that it's very sensitive to local magnetic fields, so the chip needs to be a few inches away from even a toroidal power transformer. --scott -- "C'est un Nagra.

Interesting - Scott, do you know if the INA163 suffers from the same glitch ? (nice to know BEFORE laying out the PCB) I have no idea. I have only briefly used the INA163. I do know that with the INA103, the noise floor is higher if you use the internal gain setting resistor to set it to 40 dB, compared with using an external resistor to set it to 40 dB. --scott -- "C'est un Nagra.

I like to design with discretes for the front-end. As for output stage, SSM just do a handy package. You can do just as well with other ICs if you know how to configure them. What quality can I expect? Pretty reasonable knowing SSM. Since the place on a 160mmx100mm PCB is limited what compromises can be made. And which shall not? That's a big pcb. What else is on it ? What compromises do you think you might *need* to make ? Graham |

And for about 250 there are some solutions out there. At first I wanted to wait for the RME octapre. But 1000$ for a nearly unused device... Would be another nice mic.

What else is on it ? What compromises do you think you might *need* to make ? I forgot to say, 6-8 preamps. I skiped the idea to buy a mixer for that. I really dont't need it. I have 8 usable to good preamps and channel strips. I just need at least 6 additional preamps. Compromises means layout compromizes. |
