LINE TRANSFORMERS AND ATTENUATORS
Line Matching Transformers
A great way to add gain without buying a relatively expensive preamp. Short on gain and don't have the cash for a preamp? Or starting out and want to put as much money into your mics as possible and save for a preamp later (a wise choice) - line matching transformers are the way to go. Clean, inexpensive gain to hold you over until you get the cash to support your upgrade bug. Some options:
Audio Technica (http://www.audiotechnica.com (http://www.audiotechnica.com))
CP8201
CP8305
Hosa (http://www.hosatech.com (http://www.hosatech.com))
MIT-176
Shure (http://www.shure.com (http://www.shure.com))
A85F
Attenuators
Used to reduce a strong signal. For example, if the signal from your mics overloads your preamps inputs, attenuate the signal prior to the preamp using attenuators. Some commonly used attenuators:
Shure (http://www.shure.com (http://www.shure.com))
A15AS | Switchable attenuation: -15, -20, or -25 dB.
Audio Technica (http://www.audiotechnica.com (http://www.audiotechnica.com))
8202 | Switchable attenuation: -10, -20, or -30 dB.
Radio Shack
Sorry, don't have a part # handy, but roll by your local RS and they'll probably have 'em.

is there any reason why i should not switch the shure a15as on the fly..? can i be recording and change the setting, or do i have to have nothing going through the device when switching the attenuatioin..?
