Title: attenuation - where/how is the best way..?
Post by: macdaddy on January 28, 2009, 04:19:21 PM

i use the akg c422, and alot of times i find myself needing to attenuate the signal, and i have been using the pad on the mic. then i read this (http://taperssection.com/index.php/topic,82341.msg1093698.html#msg1093698):

Thus any built-in pads of that type (which, as I said, are the most common type) should never be used unless they are needed to prevent the microphone itself  from overloading.

oops. well i understand the logic, that you are adding noise, and so that leaves me with two options: using the -20db pad on the tmod-p2 (the recorder i use), or using those shure a15as inline attenuators i have. specifically, will the use of one provide better sonic results, or are they the same..? obviously, i would rather run the pad on the p2 'cos it is less gear, but if there are sonic advantages to using the shures, i would use those instead...

thanks, in advance, for any advice, information and insight.

You need to find out where the overloading apear. If your microphones are overloading, you need to use the built-in pad (-10 or -20dB). The output of the microphone is 5mV/Pa (94dB) and that is on the low side. What kind of gain is provided by your mic preamp? Maybe you what input level it can take?
