When I record mic in on my machine I get a distorted signal even when my levels never go over 0db, why ? Most portable DAT machines are designed for a wide range of applications. Unfortunately, they do not include recording live rock n' roll at high SPL's. The input to the mic preamplifier overloads and is the cause of distortion. The mic preamp is before the record level control, so its gain is not adjustable. With a fixed gain structure the mic preamp can be overdriven and the level meter will not show it. This is a common problem with the Sony D3/7/8/D100/PCM-M1 and the Tascam DAP-1. Oade Audio offers performance upgrades available for both of these models that will eliminate this problem and lower the noise floor of the preamp. This offers the user freedom from overload distortion and less noise !! Back to General FAQ Back to Tapers Section Back to Oade Audio Home
