Stam Audio 1073MPA Preamplifier

Full Description

Advanced replica of classic British EQ

Stam Audio brings the Iconic sound of 1970s British preamps in the form of the 1073MPA. This 19-inch rack-mountable 2-channel preamp is a clone of early British sound engineering technology found in recording studios and broadcasting stations around the globe. The 1073MPA recreates warm, gritty sounds associated with 1073-style preamps installed in world-class mixing consoles. This sound is often referred to as "British Sound" or "British Iron" and is sought after by producers and music enthusiasts.

Built with the finest components

The build of the 1073MPA comprises high-quality components to replicate the characteristics and sonority of the 1073, such as tantalum and polystyrene capacitors. The intricate design covers every precise detail of the original models, it incorporates vintage Carnhill/St Ives input and Sowter output transformers that made the 1073 preamp a successful, timeless classic. The transformers provide excellent low-frequency responses.

Rack mounted British iron

The 1073MPA is a 19-inch rack-mount, which is suitable for your modern mixing console or amp rack. XLR connectors provide balanced signals on both input and output of the preamp and an external power supply ensures a noise-free circuit. The retro style faceplate houses the controls. With 2 channels the 1073MPA can amplify two instruments or microphones with a polarity inverter button to resolve fazing issues. A 48V phantom power button on each allows you to use the preamp with studio mics that require it. Controls for the impedance booster and the line level are next to the 48V and Polarity. The main gain control is a stepped Marconi dial that allows you to select your volume in intervals and the trim knob allows for more precise volume adjustment. Each channel has a 1/4-inch jack direct input for instruments such as guitars. The Stam 1073MPA is a fantastic throwback to iconic British audio engineering that took over the music charts. This item will help you obtain the warm and gritty sound that dominated the last 30 years of the 20th century music scene.
