CM49

Common name: Advanced Audio CM49

Production Status: In production

The Advanced Audio CM49 was designed with the vintage Neumann M49 in mind. As with all of our microphones, we did not clone one of the vintage M49 versions. Rather, we used modern designs, circuitry, and components while maintaining the sound of this classic microphone famous for producing smooth pop and soulful vocals. The M49 gained notoriety capturing the distinct vocals of Bob Dylan, Miles Davis, Billie Holliday, and the Beatles ´Help´ overdubs. Additionally, it is considered the classical orchestra workhorse. Renowned for the lush vocal sounds of the 50’s, Advanced Audio’s CM49 touts the same natural and accurate reproduction, but captures a more refined high-end and smooth bottom-end. By using Advanced Audio’s modern 2-stage tube mic circuitry, the CM49 has a much lower output impedance, yielding more headroom than the original. The hand-selected Electro Harmonix 6072a valve is one of the quietest hifi tubes available. The output transformer is our own custom-wound BV18 transformer. This dual bobbin transformer has bi-metal (a mixture of iron and nickel) laminations. It provides very fast damping, resulting in a clear, undistorted transient response. The 8:1 ratio windings, along with the dual-stage circuit, deliver > +10dBu, with less than 1% of distortion.
